Aluminium foil floating above the induction cooktop thanks to eddy currents induced in it. A conductor can be levitated above an electromagnet (or vice versa) with an alternating current flowing through it. This causes any regular conductor to behave like a diamagnet, due to the eddy currents generated in the conductor.Thompson, Marc T. Eddy current magnetic levitation, models and experiments.

A magnetic dipole over the superconducting surface. The field between the magnet and surface is the same as between this magnet and a symmetric one. The method of images may also be used in magnetostatics for calculating the magnetic field of a magnet that is close to a superconducting surface. The superconductor in so-called Meissner state is an ideal diamagnet into which the magnetic field does not penetrate.

The superconductor is first heated strongly, then cooled with liquid nitrogen to levitate on top of a diamagnet. In a very strong magnetic field by means of diamagnetic levitation, even small live animals have been levitated. It is possible to levitate pyrolytic graphite by placing thin squares of it above four cube magnets with the north poles forming one diagonal and south poles forming the other diagonal. Researcher have even successfully levitated (non-magnetic) liquid droplets surrounded by paramagnetic fluids.

An ideally hard superconductor is a type II superconductor material with an infinite pinning force. In the external magnetic field it behaves like an ideal diamagnet if the field is switched on when the material is in the superconducting state, so-called "zero field cooled" (ZFC) regime. In the field cooled (FC) regime, the ideally hard superconductor screens perfectly the change of the magnetic field rather than the magnetic field itself. Its magnetization behavior can be described by Bean's critical state model.

Diamagnetism is a quantum mechanical effect that occurs in all materials; when it is the only contribution to the magnetism, the material is called diamagnetic. In paramagnetic and ferromagnetic substances, the weak diamagnetic force is overcome by the attractive force of magnetic dipoles in the material. The magnetic permeability of diamagnetic materials is less than the permeability of vacuum, μ0. In most materials, diamagnetism is a weak effect which can only be detected by sensitive laboratory instruments, but a superconductor acts as a strong diamagnet because it repels a magnetic field entirely from its interior.
