Magnetism is an invisible force or field caused by the unique properties of certain materials. In most objects, electrons spin in different, random directions. This causes them to cancel each other out over time. In magnets the molecules are uniquely arranged so that their electrons spin in the same direction.
But first let's understand what is physics!
