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.
Jan 16, 2024 · In this article, we will understand the meaning of electromagnet, properties of electromagnet, advantages and disadvantages, the right-hand rule of electromagnetic field, uses of electromagnet, and the difference between permanent magnets and electromagnet.
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.
An electro magnet is a temporary magnet made by winding wire around an iron core. When current flows in the coil the iron becomes a magnet, and when the current is turned off it looses it's magnetic properties. Suggest Corrections. 333. Similar questions. Q. What is electromagnet.

Electromagnets are magnets whose magnetic field is generated by electricity. The magnets used for decoration on your refrigerator are different from this type. It is made from metal materials that are permanently magnetized. These magnets are used in refrigerators because they continuously generate magnetic fields.
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.
The magnetic field, produced with the flow of an electric current in a magnet, is known as the electromagnet. It usually consists of a wire wound in a coil, and the current through the wire creates the magnetic field, which is concentrated in the hole, representing the center of the coil.
