1. It is a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
2. a core of magnetic material (such as iron) surrounded by a coil of wire through which an electric current is passed to magnetize the core.
DEFINITION:
1. An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil.
2. An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.
An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.
Explanation:
An electromagnet is a device that sends electricity through a coil of wire to produce a magnetic field. Electromagnets are used in millions of devices around the world, from hard disk drives and MRI machines, to motors and generators.
