Question

what happen to the magnetic property of the nail after dropping it several times? why

Answer 1

Explanation:

losses it magnrtic property because chage in arrangement

Answer 2

Magnetic property of the nail:

Nails with magnetic properties lose their characteristics when dropped several times. According to the molecular theory of magnetism, each particle of a permanent magnet is arranged in such a way that they exhibit and add up their magnetic strength.

This is because each molecule of a permanent magnet is a magnet by itself. But, if the permanent magnet is dropped down several times then the object gets disarranged. Hence the magnetic field no longer gets added up and finally, the permanent magnet loses its magnetic effect.
