Question

At what temperature do magnets lose their magnetism?


Open in App
Solution

  1. The magnet loses its magnetism above the Curie temperature.
  2. There is a reduction in the magnetism of the magnets when heated because the particles in the magnet start moving faster.
  3. This fast movement of the particles misaligns the magnetic domains and reduces magnetism.

Examples :

  1. Heating a magnet strongly.
  2. Hammering the magnet several times or repeated hammering.
