Magnetism is a force of nature produced by moving electric charges. Sometimes these motions are microscopic and inside of a material known as magnets. Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged ...
Photons are the force carriers not only for magnets but also for electrostatic phenomena like static electricity, and it's whyelectromagnetismis the term we use for effects produced by these phenomena – including light, which is an electromagnetic wave.

Einstein liked to tell a story about when he was five years old and sick in bed how his father brought him a magnetic compass that was the first he�d ever seen. He was fascinated by the fact that the needle always pointed north, pulled by an invisible force. No matter how he twist...

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Learn more abo
electromagnetic radiation. During the late 1960s, physicists discovered that other forces in nature have fields with a mathematical structure similar to that of theelectromagnetic field. These other forces are thestrong force, responsible for theenergyreleased innuclear fusion, and theweak force, ...
