What is the difference between solenoid and electromagnet

A solenoid is an inductor. Not all the inductors are solenoids. A solenoid is a coil with a ferrous core that moves. An inductor is a wire coil with a fixed core, which may or may not be present. The magnetic field strength for this uniform field can be given by:.

When the solenoid is palced in a material with a relative permeability , the term is replaced by , where is the relative permeability of the material. An electromagnet is a magnet whose magnetic properties are produced by an electric current. When the current is switched off, the electromagnet no longer displays magnetic properties.

The simplest way to make an electromagnet is to make a solenoid, pass current through it and then place a piece of soft iron inside the solenoid. Cute Hell Jul 23, Upvote 8.

Electromagnets can be of various types ranging from simple solenoids to superconducting electromagnets , bitter electromagnets to explosively pumped flux compression generator.

Thus, electromagnet can be considered as a universal set and solenoid is one of its subsets. Sign up to join this community.
