Magnetic Confinement Demonstration: Motion of Charged Particles
... The circular motion produced by a magnetic force on a charged particle can be understood by using Newton’s Second Law, F = ma. The force exerted by a magnetic field, B, on a moving particle of electrical charge, q, with velocity, v, is F = qvB whenever v and B are perpendicular. Setting this equal t ...

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.
