Diamagnets ( which induce a negative moment ) are attracted to field minima, and there can be a field minimum in free space.
12.
For example, a superconducting sample, which can be considered either as a perfect diamagnet or an ideally hard superconductor, easily levitates in an ambient external magnetic field.
13.
It is also more diamagnetic ( ? = " 4?0 " 4 ) against the cleavage plane, exhibiting the greatest diamagnetism ( by weight ) of any room-temperature diamagnet.
14.
Superconductors may be considered "'perfect diamagnets "', and completely expel magnetic fields due to the Meissner effect when the superconductivity initially forms; thus superconducting levitation can be considered a particular instance of diamagnetic levitation.
