... horizontally from back wall towards the front wall, is deflected by a strong magnetic field to your right side. What is the direction of magnetic field? Solution: Here , An electron beam, moving horizontally from back wall towards the front wall so, the direction of current will be in the opposite d ...

... Lenz's Law An induced current flows in such a direction that the induced magnetic field it creates opposes the action of the inducing magnetic field. If you find this statement of Lenz’s law confusing, you are not alone. The problem stems from the number of events which are occurring simultaneously. ...

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.
