Question

write the different ways through which magnet can be made to lose their magnetism.
​

Answer 1

Via heat: ferromagnet materials will lose their magnetism if heated above a point known as the Curie temperature. Via a demagnetizing magnetic field: permanent magnets exhibit a characteristic called coercivity, which is the ability of a material to withstand being demagnetized by an applying an magnetic field.

Answer 2

Answer:

Magnetized metal objects lose their magnetism if the objects become sufficiently hot.

With increasing temperature, atoms in a metal vibrate more energetically, eventually it causes the atoms to lose their magnetic alignment and any magnetic field the metal possessed.

Hope this helps you....
