When she wanted to be cheerful, she requested Kerner to magnetise the water she drank, by playing the Jew's-harp.

We might also magnetise the car, say by surrounding it with a coil of wire excited from an accumulator on board.

The Met Office discovered the helicopters act as a conductor for the lightning, which can knock out instrument panels, heat up components and magnetise navigational equipment.

A recording signal which generates a magnetic field strength less than tape's coercivity is unable to magnetise the tape and produces little playback signal. Bias increases the signal quality of most audio recordings significantly by pushing the signal into more linear zones of the tape's magnetic transfer function.

Rebound tonometers determine intraocular pressure by bouncing a small plastic tipped metal probe against the cornea. The device uses an induction coil to magnetise the probe and fire it against the cornea. As the probe bounces against the cornea and back into the device, it creates an induction current from which the intraocular pressure is calculated. The device is simple and easy to use and self-use versions are available.

The domains rotate sideways to a halfway position that weakens the readability of the domain and relieves the magnetic stresses. A write head magnetises a region by generating a strong local magnetic field, and a read head detects the magnetisation of the regions. Early HDDs used an electromagnet both to magnetise the region and to then read its magnetic field by using electromagnetic induction. Later versions of inductive heads included Metal In Gap (MIG) heads and thin film heads.

Called upon to stop "evil white ones" (Kablunets) from using time bombs to destroy fish and other food stocks in the North, Nelvana and her brother Tanero are assisted by Koliak and use the Northern Lights as a gigantic magnet to magnetise the enemy bombs towards the sky by destroying them harmlessly. Commander Toroff, attacks Nelvana and her brother from his Devil Ship with killer boats. Nelvana and Tanero land on Toroff’s ship, and Nelvana instructs Tanero to destroy Toroff's fleet and killer boats. Meanwhile, Nelvana searches Toroff's quarters looking for his plans. Nelvana comes across Toroff’s plans but is soon captures.

There are four possible known methods: # Cooling in field; # Zero field cooling, followed by slowly applied field; # Pulse magnetization; # Flux pumping; Any of these methods could be used to magnetise the superconductor and this may be done either in situ or ex situ. Ideally the superconductors are magnetised in situ. There are several reasons for this: first, if the superconductors should become demagnetised through (i) flux creep, (ii) repeatedly applied perpendicular fields or (iii) by loss of cooling then they may be re- magnetized without the need to disassemble the machine. Secondly, there are difficulties with handling very strongly magnetized material at cryogenic temperatures when assembling the machine.

The width of the head gap is also critical - the narrower the gap, the better the head will be - a narrow gap gives much better transcription in the magnetic domain (which equals to more output with high frequency signals in the case with playback heads). The desirability for a narrow gap means that most practical heads are made by forming a narrow V-shaped groove in the back face of the core, and grinding away the front face until the V-groove is just breached. In this way, gaps of the order of micrometres are achievable. A record head, on the other hand, has a gap typically six times larger than that of the replay head, this gives a larger flux to magnetise the tape.

This was not suspected until 1826, when Felix Savary in France, and later (1842) Joseph HenryJoseph Henry, "On induction from ordinary electricity; and on the oscillatory discharge", Proceedings of the American Philosophical Society, vol 2, pp.193–196, 17 June 1842 in the US noted that a steel needle placed close to the discharge does not always magnetise in the same direction. They both independently drew the conclusion that there was a transient oscillation dying with time.Blanchard, pp.415–416 Hermann von Helmholtz in 1847 published his important work on conservation of energyHermann von Helmholtz, Uber die Erhaltung der Kraft (On the Conservation of Force), G Reimer, Berlin, 1847 in part of which he used those principles to explain why the oscillation dies away, that it is the resistance of the circuit which dissipates the energy of the oscillation on each successive cycle.
