- Electric charges are surrounded by an electric field. Moving electric charges are also surrounded by a magnetic field. Electric current flowing through a coil of wire is an electromagnet. The spin of the electron makes it behave like a very small magnet. Electric currents in the molten outer core of the Earth make it behave like a giant magnet.

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.
Jul 18, 2024 · Electromagnetism is a fascinating area of physics that explores how electric charges produce magnetic fields, and vice versa. This fundamental interaction is governed by the laws of physics and is crucial for understanding how everything from electric motors to MRI machines operates.
Key points. An electromagnet uses an electrical current to generate a magnetic field. There are three ways to strengthen an electromagnet: increasing current. increasing the number of turns of...
Sep 6, 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.
