Magnet-ism

This is a lazy post. First, a video of a ferrofluid, a liquid with creepy nanoscale magnets suspended in it. Who ever said physics wasn't evil?



Speaking of evil, here is a famous frog levitating in a magnetic field. Everything is diamagnetic if the external field is strong enough...but only frogs are unlucky enough to get used in these experiments.
