Question

Hammering of an object for demagnetisation

Answer 1

Answer:

Materials are demagnetized when the magnetic molecules inside a substance are randomly assigned, causing disorder inside the previously aligned magnetic material.

It is also possible to demagnetize a magnet by hitting the ends of the magnet with a hammer, which will alter the order of the magnet. To hit a magnet with an object in general, applying force, is a good mechanism to achieve this objective.
