What is electromagnetism?
Quick Answer
Electromagnetism is the fundamental force that acts between electrically charged particles and produces electric and magnetic fields. It governs light, electricity, magnetism, and most everyday forces.
The Full Story
Electromagnetism is the interaction responsible for electric charge, magnetic fields, and light. It explains why electrons stay bound to atoms, why magnets attract or repel, and why radio waves, visible light, and X-rays are all part of the electromagnetic spectrum. James Clerk Maxwell unified electricity and magnetism in the 1860s with a set of equations that predicted electromagnetic waves. In modern physics, the electromagnetic force is carried by photons.
