The E _ J power law can be used to describe the phenomenon of flux-creep in which a superconductor gradually loses its magnetisation over time.

In 2013 Rasing won a 2, 5 million euro Advanced Grant by the European Research Council for a research proposal titled'magnetisation at its fastest '.

When played out loud, this is referred to as Barkhausen noise, the magnetisation of the magnet increases in discrete steps as a function of the flux density.

What is required for in situ magnetisation is a magnetisation method in which a relatively small field of the order of milliteslas repeatedly applied is used to magnetize the superconductor.

26.
In alternating current electromagnets, such as are used in motors, the core's magnetisation is constantly reversed, and the remanence contributes to the motor's losses.
27.
Instead of creating a magnetisation distribution in analog recording, digital recording only needs two stable magnetic states, which are the + Ms and-Ms on the hysteresis loop.
28.
Analogously to polarisation, we get magnetisation \ mathbf { M }, corresponding to a " bound " current density, when a material is penetrated by a magnetic field.
29.
Equivalently, we have to specify the dependence of the polarisation ( hence the bound charge ) and the magnetisation ( hence the bound current ) on the applied electric and magnetic field.

Magnetic media are inherently non-linear, but AC bias was the means whereby the magnetisation of the recording tape was made linearly proportional to the electrical signal which represents the audio component.
