Magnetic Dipole Moment of a Neodymium Magnet The Experiment
... The dipole moment of a magnet has its origins in the motion if the electrons in the material. Electrons orbits a nucleus, for example, act somewhat like a current going round a tiny circular circuit. For a variety of reasons (mostly quantum mechanical) the dipole moment of an atom is rarely much big ...

Superconducting magnet
A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic fields than all but the strongest electromagnets and can be cheaper to operate because no energy is dissipated as heat in the windings. They are used in MRI machines in hospitals, and in scientific equipment such as NMR spectrometers, mass spectrometers and particle accelerators.
