Diamagnetism-  if you hang a wooden toothpick in a magnetic field, the ends will repel the field, and it'll end up aligning across the field. This is a convenient way to remember the name of this kind of magnetism, diamagnetism, since dia means "across," like the diameter measured across a circle. Diamagnetic materials will repel a magnet, and a diamagnetic compass will point across the magnetic field. That is, it will orient east west.

As weak as it, diamagnetism is pretty darn awesome, because it's a repulsive effect. Any diamagnetic material will levitate in a strong enough magnetic field, like this chunk of graphene. Or, since water is diamagnetic, this frog. In principle, humans could also be levitated this way, though the magnetic fields required would be enormous.
