If a powerful magnet (such as a supermagnet) is covered with a layer of water (that is thin compared to the diameter of the magnet) then the field of the magnet significantly repels the water. This causes a slight dimple in the water's surface that may be seen by a reflection in its surface. Diamagnets may be levitated in stable equilibrium in a magnetic field, with no power consumption. Earnshaw's … WebThe conduction-electron diamagnetism has been calculated for the three-dimensional band structure of graphite.
