... 10. The magnetic field B inside a long ideal solenoid depends on ________. Ans. B = µ0ni so the magnetic field depends on the number of turns per unit length, the current through the solenoid and permeability of medium within the solenoid. For instance if an iron core is placed inside the solenoid 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.
