Behavior of a Collection of Magnets
... We know that an unmagnetized (unrubbed) nail does not interact with another unmagnetized nail. We also know that a magnetized (rubbed) nail does interact with another magnetized or unmagnetized nail, even when they don’t touch.

Interactions between Electricity and Magnetism
... Mag/Elec Interactions Electro-magnets If you coil a wire into a helical form (like wrapping a wire around a cylinder) and run a current through it, each circular coil creates a small mag field. The mag field from each coil “adds up” to create what looks like a magnet with a North and South po ...

So how does an electricity generator work
... An electric generator converts mechanical energy into electrical energy. It is based on the principle of electromagnetic induction, a scientific law that was discovered by British scientist Michael Faraday and American scientist Joseph Henry in 1831. The principle states that when an electric conduc ...

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.
