Faraday’s law of induction describes how an electric current produces a magnetic field and, conversely, how a changing magnetic field generates an electric current in a conductor. English physicist Michael Faraday gets the credit for discovering magnetic induction in 1830; however, an American physicist, Joseph Henry, independently made the same discovery about the same time, according to the University of Texas. 

It is impossible to overstate the significance of Faraday’s discovery. Magnetic induction makes possible the electric motors, generators and transformers that form the foundation of modern technology. By understanding and using induction, we have an electric power grid and many of the things we plug into it.

Faraday's law was later incorporated into the more comprehensive Maxwell’s equations, according to Michael Dubson, a professor of physics at the University of Colorado Boulder. Maxwell’s equations were developed by Scottish physicist James Clerk Maxwell to explain the relationship between electricity and magnetism, essentially uniting them into a single electromagnet force and describing electromagnetic waves that make up radio waves, visible light, and X-rays.
