What is the relationship between electricity and magnetism?

Electricity and magnetism are two aspects of the same physical phenomenon: electromagnetism. When electric charges move, they create magnetic fields. Similarly, changing magnetic fields can induce electric currents. This close relationship means that a change in one field can influence the other. For example, an electric current in a wire produces a magnetic field around it, and a moving magnet near a wire can generate an electric current. This principle is the foundation for many devices, such as electric motors and transformers. The connection was formalized by James Clerk Maxwell through his famous equations.
