What is the electromagnetic force?
Quick Answer
The electromagnetic force is the interaction between electric charges and magnets. It explains electricity, magnetism, light, and most everyday chemical and material behavior.
The Full Story
The electromagnetic force acts between charged particles and is responsible for electric fields, magnetic fields, and electromagnetic radiation such as visible light. It is carried by photons, which are massless and travel at the speed of light in vacuum. James Clerk Maxwell unified electricity and magnetism in the 1860s, and quantum electrodynamics later described the force at the particle level. Because it has infinite range, it shapes everything from atoms and molecules to radio, X-rays, and chemistry.
