Superconductors

Superconductors may be considered perfect diamagnets (μr = 0), and have the additional property of completely expelling magnetic fields due to the Meissner effect when the superconductivity initially forms. The levitation of the magnet is further stabilized due to flux pinning within the superconductor; this tends to stop the superconductor leaving the magnetic field, even if the levitated system is inverted.

These principles are exploited by EDS (Electrodynamic Suspension), superconducting bearings, flywheels, etc.

In trains, a very strong magnetic field is required to levitate a massive train. The JR–Maglev trains have superconducting magnetic coils, but the JR–Maglev levitation is not by the Meissner effect.
