Question

Explain what happens to the domain in a bar magnet if:

You cut the magnet in half
You drop the magnet onto a hard surface. How does each incident affect the magnetism of the magnet?

Answer 1

1)Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.

2)Permanent magnets can lose their magnetism if they are dropped or banged on enough to bump their domains out of alignment. ... The reason that would be hard to bump a piece of iron and make it magnetic is because of the way vibrations propagate in the material.
