Lodestones, suspended so they could turn, were the first magnetic compasses. The earliest known surviving descriptions of magnets and their properties are from Greece, India, and China around 2500 years ago. The properties of lodestones and their affinity for iron were written of by Pliny the Elder in his encyclopedia Naturalis Historia.Pliny the Elder, The Natural History, BOOK XXXIV.

This inhomogeneous crystalline structure gives this variety of magnetite sufficient coercivity to remain magnetized and thus be a permanent magnet. The other question is how lodestones get magnetized. The Earth's magnetic field at 0.5 gauss is too weak to magnetize a lodestone by itself. The leading theory is that lodestones are magnetized by the strong magnetic fields surrounding lightning bolts.

One of the earliest known references to lodestone's magnetic properties was made by 6th century BC Greek philosopher Thales of Miletus, whom the ancient Greeks credited with discovering lodestone's attraction to iron and other lodestones. The name magnet may come from lodestones found in Magnesia, Anatolia.The Greek term μαγνῆτις λίθος magnētis lithos (see Platonis Opera, Meyer and Zeller, 1839, p. 989) means "Magnesian stone".

Ancient people learned about magnetism from lodestones (or magnetite) which are naturally magnetized pieces of iron ore. The word magnet was adopted in Middle English from Latin magnetum "lodestone", ultimately from Greek (magnētis [lithos])Platonis Opera , Meyer and Zeller, 1839, p. 989. meaning "[stone] from Magnesia",The location of Magnesia is debated; it could be the region in mainland Greece or Magnesia ad Sipylum. See, for example, a part of ancient Greece where lodestones were found.

Paracelsus Paracelsus (1493–1541), a Swiss, was the first physician to use magnets in his work. Many people claimed to have been healed after he had passed magnets (lodestones) over their bodies.

He provides methods for determining the north and south poles of a magnet, and he describes the effects magnets have upon one another, showing that like poles repel each other and unlike poles attract each other. He also treats the attraction of iron by lodestones, the magnetization of iron by lodestones, and the ability to reverse the polarity in such an induced magnet. Peregrinus attributed the Earth's magnetism to the action of celestial poles, rather than to the terrestrial poles of the planet itself.

One of the first drawings of a magnetic field, by René Descartes, 1644, showing the Earth attracting lodestones. It illustrated his theory that magnetism was caused by the circulation of tiny helical particles, "threaded parts", through threaded pores in magnets.

Many early scientists attributed the magnetism of lodestones to two different "magnetic fluids" ("effluvia"), a north-pole fluid at one end and a south-pole fluid at the other, which attracted and repelled each other in analogy to positive and negative electric charge. However, an improved understanding of electromagnetism in the nineteenth century showed that the magnetism of lodestones was properly explained not by magnetic monopole fluids, but rather by a combination of electric currents, the electron magnetic moment, and the magnetic moments of other particles. Gauss's law for magnetism, one of Maxwell's equations, is the mathematical statement that magnetic monopoles do not exist. Nevertheless, Pierre Curie pointed out in 1894 that magnetic monopoles could conceivably exist, despite not having been seen so far.

Time seems to freeze as Grubbs keeps on peering into the chess room. They return and it seems that Bec has made a deal with Lord Loss, and this assures Grubbs that Bec has betrayed them. For as Bec goes back to her room she hugs Lord Loss after he has agreed to something. Something to do with lodestones.

The magnetic field of the Earth aligns the domains, leaving the iron a weak magnet. Drawing of a medical treatment using magnetic brushes. Charles Jacque 1843, France. Magnetism was first discovered in the ancient world, when people noticed that lodestones, naturally magnetized pieces of the mineral magnetite, could attract iron. The word magnet comes from the Greek term μαγνῆτις λίθος magnētis lithos,Platonis Opera, Meyer and Zeller, 1839, p. 989.

Plato’s argument is supposed to be an early example of a so-called genetic fallacy since his conclusion arises from his famous lodestone (magnet) analogy. Ion, the rhapsode “dangles like a lodestone at the end of a chain of lodestones. The muse inspires the poet (Homer in Ion’s case) and the poet inspires the rhapsode.”Sonkowsky, R. P (1983) “Oral Performance and Ancient Greek Literature,” Thompson, D. W., ed.

While in England studying archaeology, Sanborn endeavored to create a structure out of stone to gain a better insight on Romanesque sculptures. From this he has created many works of art that deal with invisible forces. These include the coriolis effect and its use of Newton's laws of motion that govern the motion of an object in an inertial frame of reference. He has also worked on pieces that implemented the Earth's magnetic field using lodestones.

Similar behavior is exhibited by some iron compounds, such as the ferrites and the mineral magnetite, a crystalline form of the mixed iron(II,III) oxide (although the atomic-scale mechanism, ferrimagnetism, is somewhat different). Pieces of magnetite with natural permanent magnetization (lodestones) provided the earliest compasses for navigation. Particles of magnetite were extensively used in magnetic recording media such as core memories, magnetic tapes, floppies, and disks, until they were replaced by cobalt-based materials.

As a result of oppressions and tribute demanded from them by Laputa, the Lindalinians rebelled against their governor and constructed tall towers at each of the four corners of the city. On top of these, they placed powerful lodestones, or magnets. The result of this was that when Laputa approached them, it was pulled toward these towers more swiftly than the king had expected. As a test, the Laputans then dropped several pieces of adamant, the substance from which their island was constructed.

Kempelen made it a point to traverse the room during the match, and invited observers to bring magnets, irons, and lodestones to the cabinet to test whether the machine was run by a form of magnetism or weights. The first person to play against the Turk was Count Ludwig von Cobenzl, an Austrian courtier at the palace. Along with other challengers that day, he was quickly defeated, with observers of the match stating that the machine played aggressively, and typically beat its opponents within thirty minutes.Standage, 30.

Lodestone attracting some iron nails Hall of Gems of the Smithsonian Lodestone attracting small bits of iron A lodestone is a naturally magnetized piece of the mineral magnetite. They are naturally occurring magnets, which can attract iron. The property of magnetism was first discovered in antiquity through lodestones. Pieces of lodestone, suspended so they could turn, were the first magnetic compasses, and their importance to early navigation is indicated by the name lodestone, which in Middle English means "course stone" or "leading stone", from the now-obsolete meaning of lode as "journey, way".

The process by which lodestone is created has long been an open question in geology. Only a small amount of the magnetite on the Earth is found magnetized as lodestone. Ordinary magnetite is attracted to a magnetic field like iron and steel is, but does not tend to become magnetized itself; it has too low a magnetic coercivity (resistance to demagnetization) to stay magnetized for long. Microscopic examination of lodestones has found them to be made of magnetite (Fe3O4) with inclusions of maghemite (cubic Fe2O3), often with impurity metal ions of titanium, aluminium, and manganese.

Any writings Nicander may have made on the subject have since been lost. Written in approximately 600 CE, book XVI of Etymologiae by Isidore of Seville tells the same story as Pliny, but places Magnes in India. This is repeated in Vincent of Beauvais' Miroir du Monde (c. 1250 CE) and in Thomas Nicols' 1652 work, Lapidary, or, the History of Pretious Stones, wherein he describes Magnes as a "shepherd of India, who was wont to keep his flocks about those mountains in India, where there was an abundance of lodestones".

Hamilton was born on 22 March 1686 to James Hamilton and his wife Elizabeth Reading. His elder brother Robert was baptized on 12 July 1687 but died shortly afterwards, making James the heir apparent, with the style of "Lord Paisley", when his father succeeded as 6th Earl of Abercorn in 1701. A scientist, Hamilton became a Fellow of the Royal Society on 10 November 1715, and published Calculations and Tables on the Attractive Power of Lodestones, a book on magnetism, in 1729. He was a Freemason and was Grand Master of the Premier Grand Lodge of England in 1725–1726.

According to Aristotle, Thales thought lodestones had souls, because iron is attracted to them (by the force of magnetism).Nathan Ida, Engineering Electromagnetics, Springer, 2015 Aristotle defined the soul as the principle of life, that which imbues the matter and makes it live, giving it the animation, or power to act. The idea did not originate with him, as the Greeks in general believed in the distinction between mind and matter, which was ultimately to lead to a distinction not only between body and soul but also between matter and energy. If things were alive, they must have souls.

There are some unsourced claimsMark E. Eberhart(2007):Feeding the fire: the lost history and uncertain future of mankind's energy, p.14 that a perpetual motion machine called the "magic wheel" (a wheel spinning on its axle powered by lodestones) appeared in 8th-century Bavaria. This historical claim appears to be unsubstantiated though often repeated. Early designs of perpetual motion machines were done by Indian mathematician–astronomer Bhaskara II, who described a wheel (Bhāskara's wheel) that he claimed would run forever.Lynn Townsend White, Jr. (April 1960). "Tibet, India, and Malaya as Sources of Western Medieval Technology", The American Historical Review 65 (3), p. 522-526.

When a "simple child" named Bran who can run incredibly fast comes to Bec's demon-besieged rath, she and a small consignment of warriors go with him, including the chief's son, Connla, who is "largely untested" in battle; Goll, an old warrior; Lorcan and Ronan, two teenage twins; Fiachna the blacksmith; and Orna, a female warrior. During the journey, the group is attacked by demons, but luckily manage to hide near some ancient lodestones which protect them with powerful Old Magic. Eventually, Bran leads them to a crannóg, where everyone is dead except a druid, Drust. The druid tells them about a tunnel to the demons' world, and how he aims to destroy it.

Therefore, they decide to destroy as many lodestones as they can before Bec can get to them, and go to the only lodestone that they know the location of, the one at Carcery Vale. Grubbs, Kernel, Kirilli and two werewolves Curly and Moe with the help of the government and military of the world are quickly there by plane, which the werewolves hate and helicopter which they love. When they get there, they walk around Dervish's old mansion for a while, before going to the cave. They remove the dirt and go into the tunnel and the second cave with the lodestone after Kernel tells Grubbs this might be exactly what Bec and Lord Loss want them to do.
