The repulsion between bismuth and the magnets is so strong, it causes the metal to levitate. But why is bismuth so strongly ...

However, a magnet may be attracted to or repelled from another magnet. For example, bringing a north pole and a north pole together will cause the magnets to push away from each other or repel.

When this is done, the magnet in between wants to repel away from the plate above, only to find that as it gets closer to the plate below it is equally repelled, creating a stable system.
