... Q 5 If the N pole of a bar magnet is held motionless inside the large coil, how will the galvanometer deflect? (a) Positive deflection, because current flows into the red terminal of the galvanometer and out of the black terminal. (b) Negative deflection, because current flows into the black termina ...

The force that a magnetic field exerts on a charged particle moving through it is given by F = qvB sin θ = qvB , where B is the component of the field perpendicular to the particle’s velocity. Since the particle moves in a straight line, the magnetic force (and hence B , since qv ≠ 0) must be z ...

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.
