Converting a magnet to a non-magnet is called demagnetisation. Magnets are made from magnetic metals – iron, nickel and cobalt. These are the only pure metals that can be turned into a magnet.

A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail. An iron core ...

Both theoretically and, recently, experimentally, the limit for magnetic sensitivity is set at Planck’s constant – an infinitesimally small value at 6.62607015×10 Joule-seconds, and generally labeled ...

Multiferroic materials, in which electric and magnetic properties are combined in promising ways, will be the heart of new solutions for data storage, data transmission, and quantum computers.

A Korean research team has succeeded in securing a basic technology for further improving the completeness level of ...
