Trouble with Maxwell`s Electromagnetic Theory: Can Fields Induce
... The textbook says that this was “found” by Maxwell. But did Maxwell prove what the textbook says he “found”? Sadly, the answer turns out to be no. Not only that Maxwell did not prove it by any experiment but nobody proved it experimentally in the 150 years that have passed since then. What Maxwell d ...

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.
