Answers

Answered by vansh2006jaat

Explanation:

Demagnetize a Magnet by Heating or Hammering

You can get the same effect by repeatedly hammering a magnet, applying pressure, or dropping it on a hard surface. The physical disruption and vibration shake the order out of the material, demagnetizing it.

Answered by meghabiswas465

Answer:

Demagnetization randomizes the orientation of magnetic dipoles. Demagnetization processes include heating past the Curie point, applying a strong magnetic field, applying alternating current, or hammering the metal.
