An electromagnet can be defined as a magnet which functions on electricity. Unlike a permanent magnet, the strength of an electromagnet can be changed by changing the amount of electric current that flows through it. If the current flow is cut, the property of magnetism ceases to exist.
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 in the center of the coil. The magnetic field disappears when the current is turned off.
Feb 11, 2024 · The meaning of ELECTROMAGNET is 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.
Jul 2, 2024 · electromagnet, device consisting of a core of magnetic material surrounded by a coil through which an electric current is passed to magnetize the core. An electromagnet is used wherever controllable magnets are required, as in contrivances in which the magnetic flux is to be varied, reversed, or switched on and off.

Jul 15, 2024 · Electromagnetism, science of charge and of the forces and fields associated with charge. Electricity and magnetism are two aspects of electromagnetism. Electric and magnetic forces can be detected in regions called electric and magnetic fields. Learn more about electromagnetism in this article.
In physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules.
A device consisting of a coil of insulated wire wrapped around an iron core that becomes magnetized when an electric current flows through the wire. Electromagnets are used to convert electrical control signals into mechanical movements.
a device made from a piece of iron that becomes magnetic when a changing current is passed through the wire that goes around it. SMART Vocabulary: related words and phrases.

This article explains What Are Electromagnets in detail. The electromagnets are temporary magnets that are created when the electricity passes through a metal wire coil. When electricity passes through the metal coil, the electric field creates the magnetic field at the core or centre of the coil.
