MCQ
Demagnetisation of magnets can be done by
  • A
    Rough handling
  • B
    Heating
  • C
    Magnetising in the opposite direction
  • All the above

Answer

Correct option: D.
All the above
d
Demagnetization processes include heating past the Curie point, applying a strong magnetic field, applying alternating current, or hammering the metal. Demagnetization occurs naturally over time. The speed of the process depends on the material, the temperature, and other factors.
