In permanent magnets, neighboring atoms align and lock into place to create inseparable north and south poles. For other materials, magnetism can be induced by a field strong enough to coax atoms into alignment. In both cases, atoms are typically arranged in the rigid structure of a solid, glued into a grid and prevented from moving.
