Electromagnetism is a fundamental force of nature that explains the relationship between electricity and magnetism. It is based on the principle that an electric current produces a magnetic field around it, and a changing magnetic field induces an electric current. This relationship was first described by James Clerk Maxwell's equations, which show how electric and magnetic fields interact and propagate through space. Electromagnetism plays a crucial role in many aspects of modern technology, including electric motors, generators, and electromagnetic waves like light.
