Question

Suggest any three methods through which magnets can be made to lose their magnetism.​

Answer 1

Answer:

• 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.
• If a magnet is exposed to high temperatures, the delicate balance between temperature and magnetic domains is destabilized. At around 80 °C, a magnet will lose its magnetism and it will become demagnetized permanently if exposed to this temperature for a period, or if heated above their Curie temperature.
