Magnetic Levitation

The video explores different types of magnetism, focusing on diamagnetism, a weak form of magnetism present in all materials. It explains how an external magnetic field affects electrons, causing a repulsive effect. Examples include levitating diamagnetic materials like graphene and frogs. The video also touches on the complexities of nitrogen's diamagnetism and contrasts it with paramagnetism in oxygen. Finally, it discusses superconductors, which exhibit perfect diamagnetism by expelling magnetic fields entirely.
