Question

A magnetised piece of steel is repeatedly hammered. What will be the effect of this?



1.Magnet will lose its magnetism

2.Magnet will become stronger

3.The poles of the magnet will be reversed

4.No effect on magnetism of the magnet​

Answer 1

Answer:

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.

Answer 2

The poles of the magnet will be reversed
