Detailed Solution

A solenoid is a type of electromagnetic coil.
A solenoid is a term that refers to a wire coil that is used as an electromagnet. Electromagnets are magnets in which the wire is wrapped around an iron core. When an electric current is applied to the iron core, a magnetic field is formed around it. When the power is turned off, the magnetic field vanishes. The wire-wound core of the magnet is ferromagnetic or ferrimagnetic. The most common material used in the core is iron. The magnetic field created is governed by the availability of electricity. A permanent magnet does not require power, and its magnetic field cannot be controlled. Solenoids, MRI machines, hard discs, relays, motors, loudspeakers, and generators all use electromagnets.
