introduction to magnets and magnetic fields
... The diagrams below represent pivoted loops in the presence of magnetic fields. The pivot is the rod in the center of the loop. The directions of currents and fields are indicated. Use the right-hand rule to determine the direction of the force on each side of the wire and indicate the direction of t ...

ELECTROMAGNETISM
... People had tried similar experiments before, but only with static electricity, not with a moving electric current. For instance, they had hung batteries so that they were free to rotate in the earth's magnetic field, and found no effect; since the battery was not connected to a complete circuit, the ...

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.
