How can you stop a magnet from sticking to certain metals. A: … You can also redirect the magnetic flux lines into a loop to reduce the field strength away from the magnet. The easist way to do this is to put a bar of iron (like a nail) across the two poles of a horseshoe magnet.
What happens when a magnet is cut in half?
You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. 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.
