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.

Iridium (Ir)-doped Fe-Co alloy (Fe-Co-Ir) is one such material, identified through machine learning, that has been shown to possess large magnetic moments, representing the strength and ...

In atoms with filled electron shells, these magnetic moments cancel each other ... At room temperature, a pure bar of neodymium wouldn’t be a magnet at all. In fact, it would need to be chilled ...

Magnetic materials have become indispensable to various technologies that support our modern society, such as data storage devices, electric motors, and magnetic sensors.
