The Department of Terrestrial Magnetism was founded in 1904. Part of their mission included the use of two ships. The Galilee (ship) was chartered in 1905, but when it proved unsuitable for performing magnetic observations, a nonmagnetic ship was commissioned. The Carnegie (ship) was built in 1909 and completed seven cruises to measure the Earth's magnetic field before it suffered an explosion and burned.

This unique construction rendered the ship safe from magnetic mines and was the reason for her very high initial cost of approximately $3,500.000.

Amplified piezoelectric actuators have no sliding parts due to the flexural hinges and do not require lubrication. Lubrication-free performance is important for cryogenics, where traditional lubricants may freeze, and for vacuum applications, where lubricants could outgas or trap atmospheric gasses. Piezoelectric actuators can also be made with nonmagnetic materials, which allows their use in MRI machine.

The backing plate was vital; it would usually be a thick mild steel. Since this was from what vital parts of a ship's superstructure were made, it was possible to cast plastic armour in situ between existing plates and temporary wooden shuttering, usually to a thickness of . Where this was not possible, armoured plates could be factory made. Wooden backing could also be used when nonmagnetic protection was needed near the ship's compass.

Another famous vessel built on Shooter's Island was , built for the Carnegie Institution of Washington for use in magnetic surveys in the Pacific Ocean. The brigantine yacht was named after industrialist and philanthropist Andrew Carnegie, who was a friend of Mr. Downey. It was built entirely of wood and nonmagnetic metals so as not to interfere with magnetic measurements. The island came under the control of the Tidewater Oil Company in 1903.

The SRR was introduced by Pendry in 1999, and is one of the most common elements of metamaterials. As a nonmagnetic conducting unit, it comprises an array of units that yield an enhanced negative effective magnetic permeability, when the frequency of the incident electromagnetic field is close to the SRR resonance frequency. The resonant frequency of the SRR depends on its shape and physical design. In addition, resonance can occur at wavelengths much larger than its size.

A single cell SRR has a pair of enclosed loops with splits in them at opposite ends. The loops are made of nonmagnetic metal like copper and have a small gap between them. The loops can be concentric, or square, and gapped as needed. A magnetic flux penetrating the metal rings will induce rotating currents in the rings, which produce their own flux to enhance or oppose the incident field (depending on the SRRs resonant properties).

Low magnetic motors or nonmagnetic electric motors are designed to provide a reduced emanating magnetic stray field signature. These electric motors are manufactured from as little magnetic material as possible. The parts and components used to manufacture these electric motors are selected from materials with a low magnetic permeability. There are three major means of reducing the emanating magnetic stray fields of an electric motor: a dedicated electric and magnetic layout, electromagnetic shielding and additional compensating coils.

With the advent of SCUBA diving, the canteen watches, limited to 49 feet, needed to be replaced. The military needed watches, issued in 1961 for special forces, that could be submerged up to 400 ft and were nonmagnetic. A new spec needed to be included to accommodate this; spec 22717A, which superseded several previous specs. With SCUBA's commercial and public use, as well as the natural evolution of watches, the military started buying the commercial dive watches that were entering the market.

Instead, all of these iron sulfide concretions were created by the precipitation of iron sulfides within anoxic marine calcareous ooze after it had accumulated and before it had lithified into chalk. Marleka fairy stone from Stensö in Sweden. Iron sulfide concretions, such as the Kansas Pop rocks, consisting of either pyrite and marcasite, are nonmagnetic (Hobbs and Hafner 1999). On the other hand, iron sulfide concretions, which either are composed of or contain either pyrrhotite or smythite, will be magnetic to varying degrees.

All the units in pit 2 have currently uneconomic Ni grades.

From 1998 to 2000, the McLaren Formula One team used Mercedes-Benz engines with beryllium-aluminium-alloy pistons. The use of beryllium engine components was banned following a protest by Scuderia Ferrari. Mixing about 2.0% beryllium into copper forms an alloy called beryllium copper that is six times stronger than copper alone. Beryllium alloys are used in many applications because of their combination of elasticity, high electrical conductivity and thermal conductivity, high strength and hardness, nonmagnetic properties, as well as good corrosion and fatigue resistance.

Modern generators have the excitation generator on the same shaft as the turbine and main generator; the diodes needed are located directly on the rotor. The excitation current on larger generators can reach 10 kA. The amount of excitation power ranges between 0.5-3% of the generator output power. The rotor usually contains caps or cage made of nonmagnetic material; its role is to provide a low impedance path for eddy currents which occur when the three phases of the generator are unevenly loaded.

The rotor has no conductive windings or electrical connections; it consists of a solid disc of high tensile strength magnetic steel, with narrow slots cut in its circumference to create a series of narrow "teeth" that function as magnetic poles. The space between the teeth is filled with nonmagnetic material, to give the rotor a smooth surface to decrease aerodynamic drag. The rotor is turned at a high speed by an electric motor. The machine operates by variable reluctance (similar to an electric guitar pickup), changing the magnetic flux linking two coils.

1: Superexchange for MnO Superexchange was proposed by Hendrik Kramers in 1934 when he noticed that in crystals like MnO, there are Mn atoms that interact with one another despite having nonmagnetic oxygen atoms between them (Fig. 1). Phillip Anderson later refined Kramers' model in 1950. A set of semi-empirical rules were developed by John B. Goodenough and Junjiro Kanamori in the 1950s. These rules, now referred to as the Goodenough–Kanamori rules, have proven highly successful in rationalizing the magnetic properties of a wide range of materials on a qualitative level.

By far the most important step in their development was the invention of the magnetic influence firing principle, which utilizes the magnetic interference field of passing ships. Naval mines with magnetic fuzes are effective, inexpensive and easy to deploy. An electric motor produces two types of magnetic fields: a dynamic alternating stray field, whilst running and a static remnant or residual magnetic during standstill. To avoid detection it is necessary to reduceMAGNETIC SILENCING REQUIREMENTS FOR THE CONSTRUCTION OF NONMAGNETIC SHIPS AND CRAFT (METRIC), Department of Defense these signatures at the source as much as possible.

In these cases, the bore of the toroidal LGR can be partially filled with the liquid sample without requiring a special sample holder. This setup allows one to characterize the magnetic properties of, for example, a ferrofluid. Alternatively, if the liquid sample is nonmagnetic, the entire toroidal LGR can be submerged in the liquid (or gas). In this case, the dielectric properties of the sample only modify the effective capacitance of the resonator and the changes in f_0 and Q can be used to determine the complex permittivity of the sample.

Some klystrons employ permanent magnets. If a technician uses ferrous tools (which are ferromagnetic) and comes too close to the intense magnetic fields that contain the electron beam, such a tool can be pulled into the unit by the intense magnetic force, smashing fingers, injuring the technician, or damaging the unit. Special lightweight nonmagnetic (or rather very weakly diamagnetic) tools made of beryllium alloy have been used for tuning U.S. Air Force klystrons. Precautions are routinely taken when transporting klystron devices in aircraft, as the intense magnetic field can interfere with magnetic navigation equipment.

Copper also adheres poorly to TaN, but well to Ru. By depositing a layer of ruthenium on the TaN barrier layer, copper adhesion would be improved and deposition of a copper seed layer would not be necessary. There are also other suggested uses. In 1990, IBM scientists discovered that a thin layer of ruthenium atoms created a strong anti-parallel coupling between adjacent ferromagnetic layers, stronger than any other nonmagnetic spacer-layer element. Such a ruthenium layer was used in the first giant magnetoresistive read element for hard disk drives.

Two weeks later, Thrasher steamed for Charleston, South Carolina, her home port, to join Mine Force, Atlantic Fleet. But for a visit to Havana, Cuba, the wooden-hulled nonmagnetic coastal minesweeper spent the remainder of 1955, operating in South Carolina and Florida waters. She assumed duties as an active element of Mine Force, Atlantic, on the last day of the year; and, on New Year's Day 1956, her home port was changed to Yorktown, Virginia. The minesweeper's duties there included search and rescue missions for aircraft downed off the Virginia coast.

Aggressive efforts to protect nesting sites by covering them with wire mesh has significantly reduced the impact of raccoon predation on loggerhead sea turtle eggs. On Bald Head Island in North Carolina, wire mesh screens are used on every confirmed nest to prevent excavation by resident red foxes. A new concern with the steel cage technique is interference with the normal development of the nestlings' magnetic sense due to the use of ferrous wire, which may disrupt the turtles' ability to navigate properly. Efforts are underway to find a nonmagnetic material that will prevent predators gnawing through the barrier.

The dependence of the resistance of a material (due to the spin of the electrons) on an external field is called magnetoresistance. This effect can be significantly amplified (GMR - Giant Magneto-Resistance) for nanosized objects, for example when two ferromagnetic layers are separated by a nonmagnetic layer, which is several nanometers thick (e.g. Co-Cu-Co). The GMR effect has led to a strong increase in the data storage density of hard disks and made the gigabyte range possible. The so-called tunneling magnetoresistance (TMR) is very similar to GMR and based on the spin dependent tunneling of electrons through adjacent ferromagnetic layers.

MCSR magnetic system cores are free from nonmagnetic gaps, and owing to this effect in case of the reactor connection to the network it will be in no-load condition. Herewith, the value of reactive power consumed from the grid will not exceed 3% of nominal magnitude. To increase reactor load as for reactive power, its operating range should be offset to non-linear area of hysteresis characteristic; and this is achieved for the account of additional biasing of magnetic system. At connection of regulated dc voltage source to the control windings, increase of the bias flux is ensured.

Potential-pH diagrams for iron oxides in water It would thus appear microaerophilic or anaerobic conditions create a suitable potential for the formation of BMPs. Moreover, all iron absorbed by the bacteria is rapidly converted into magnetite, indicating the formation of crystals is not preceded by the accumulation of intermediate iron compounds; this also suggests the structures and the enzymes necessary for biomineralisation are already present within the bacteria. These conclusions are also supported by the fact that MTB cultured in aerobic conditions (and thus nonmagnetic) contain amounts of iron comparable to any other species of bacteria.

In a ferromagnetic workpiece, the heating is caused mainly by hysteresis, as the electromagnetic field repeatedly distorts the magnetic domains of the ferromagnetic material. In practice, most materials undergo a combination of these two effects. Nonmagnetic materials and electrical insulators such as plastics can be induction-welded by implanting them with metallic or ferromagnetic compounds, called susceptors, that absorb the electromagnetic energy from the induction coil, become hot, and lose their heat to the surrounding material by thermal conduction. Plastic can also be induction welded by embedding the plastic with electrically conductive fibers like metals or carbon fiber.

One prominent model is the so-called half-metallic ferromagnetic model, which is based on spin-polarized (SP) band structure calculations using the local spin-density approximation (LSDA) of the density functional theory (DFT) where separate calculations are carried out for spin-up and spin-down electrons. The half- metallic state is concurrent with the existence of a metallic majority spin band and a nonmetallic minority spin band in the ferromagnetic phase. This model is not the same as the Stoner Model of itinerant ferromagnetism. In the Stoner model, a high density of states at the Fermi level makes the nonmagnetic state unstable.

Copper and its alloys have a huge variety of uses that reflect their versatile physical, mechanical, and chemical properties. Some common examples are the high electrical conductivity of pure copper, low-friction properties of bearing bronze (bronze that has a high lead content— 6–8%), resonant qualities of bell bronze (20% tin, 80% copper), and resistance to corrosion by seawater of several bronze alloys. The melting point of bronze varies depending on the ratio of the alloy components and is about . Bronze is usually nonmagnetic, but certain alloys containing iron or nickel may have magnetic properties.

One of a class of new minesweepers constructed entirely of nonmagnetic materials, Implicit conducted shakedown training in California waters during mid-1954. She then began an operational pattern which was to continue for three years: minesweeping exercises, fleet maneuvers, and training cruises in the California-Mexico area. The ship then got underway from her home port, Long Beach, California, 7 August 1957 to join the U.S. 7th Fleet in the strategic Far East. During this deployment, Implicit operated with Japanese ships, Nationalist Chinese minesweepers, and with regular units of the U.S. 7th Fleet on their daily mission of maintaining peace and security in the area.

Partly owing to the "X" arrangement of the stern planes, the Type 212 is capable of operating in as little as 17 metres of water, allowing it to come much closer to shore than most contemporary submarines. This gives it an advantage in covert operations, as SCUBA-equipped commandos operating from the boat can surface close to the beach and execute their mission more quickly and with less effort. A notable design feature is the prismatic hull cross-section and smoothly faired transitions from the hull to the sail, improving the boat's stealth characteristics. The ship and internal fixtures are constructed of nonmagnetic materials, significantly reducing the chances of it being detected by magnetometers or setting off magnetic naval mines.

Those included modifying the aircraft electrical systems, replacing parts with nonmagnetic materials and adding compensators. By spring of 1953 the system was proven to be able to collect vector geomagnetic data and began operations that included intensity, dip and variation data for Project Magnet. With proven success the Hydrographic office and the United States Coast and Geodetic Survey, which also had magnetic survey responsibility over U.S. territory, arranged for the approval of the member states of the International Hydrographic Organization (IHO) of the project with provision that magnetic variation charts be published at five year intervals (Epochs) by the Hydrographic Office. The introduction of the proton precession magnetometer enabled supplemental data collection from steel hulled ships making the extreme measures used for Carnegie unnecessary.

The bank, just off Bermuda, was of particular interest at the time to the Navy's Project Artemis in which an initial installation of a horizontal and a vertical string of hydrophones were installed during 1961. A unique opportunity came on 14 November 1963 when the volcanic island of Surtsey emerged off Iceland when a project aircraft was in the area to fly a survey of the emerging island at altitude. During July 1966 the dormant island was resurveyed revealing a magnetic anomaly not evident in the original survey. By the late 1980s the RP-3D Project Magnet aircraft, specially built using nonmagnetic materials aft of the main cabin door, was named Roadrunner and had the distinctive squadron livery of international orange and white.

"Cataclysmic variables (CVs) are close binary systems consisting of a white dwarf and a red-dwarf secondary transferring matter via the Roche lobe overflow." Both fusion- and accretion-powered cataclysmic variables have been observed to be X-ray sources. The accretion disk may be prone to instability leading to dwarf nova outbursts: a portion of the disk material falls onto the white dwarf, the cataclysmic outbursts occur when the density and temperature at the bottom of the accumulated hydrogen layer rise high enough to ignite nuclear fusion reactions, which rapidly burn the hydrogen layer to helium. Apparently the only SSXS nonmagnetic cataclysmic variable is V Sagittae: bolometric luminosity of (1–10) x 1037, a binary including a blackbody (BB) accretor at T < 80 eV, and an orbital period of 0.514195 d.

A minehunter uses an imaging sonar to detect and classify targets and then sends out divers or remotely operated vehicles to inspect and neutralise the threat, often using small charges that are detonated remotely.

For example, they are often soundproofed by mounting machinery on shock absorbers or by using quiet electrical drive, low magnetic electric motors and usually have a wood, fiberglass or non-ferrous metal hull, or are degaussed to reduce magnetic signature.Design Guide and Requirements for Equipment to Achieve a Low Magnetic Signature, Ministry of Defence.

At a later point he resumed his formal graduate work with a fresh appreciation of its direct applicability to his area of interest. In 1925 Scott gained his first employment by the National Bureau of Standards in Washington, D.C. Starting in September 1927, after having held his position with the National Bureau of Standards for roughly one year, he became employed by the Department of Terrestrial Magnetism (DTM) of the Carnegie Institution of Washington, which became a pivotal point for him in his professional career. As an observer at DTM's magnetic observatory, he worked in Huancayo, Peru, in the Andes 100 miles east of Lima, before joining the staff of the famous nonmagnetic sailing ship, Carnegie, two years later. Carnegie was a vessel built for DTM's worldwide survey of the geomagnetic field.

Three methods to quench the PJTE have been documented: changing the electronic charge of the molecule, sandwiching the molecule with other ions and cyclic molecules, and manipulating the environment of the molecule. Fig. 3. Ab initio calculated energy profiles of CuF3 in the ground and lowest excited states as a function of the angle α, typical for this class of electronic e2 configurations, showing the formation of two equilibrium geometries by the PJTE on two excited states, one of which is undistorted, but magnetic, the other being distorted, but nonmagnetic Hidden PJTE, spin crossover, and magnetic-dielectric bistability. As mentioned above, there are molecular systems in which the ground state in the high- symmetry configuration is neither degenerate to trigger the JTE, nor does it interact with the low-lying excited states to produce the PJTE (e.g., because of their different spin multiplicity). In these situations the instability is produced by a strong PJTE in the excited states; this is termed “hidden PJTE” in the sense that its origin is not seen explicitly as a PJTE in the ground state.
