Question

If you cut a magnet in half does each half become a magnet

Answer 1

yes if you cut a magnet into two halves then halved act as a magnet

Answer 2

Think of a magnet as a bundle of tiny magnets, called magnetic domains, that are closely packed together. Each one reinforces the magneticfields 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.
