Michael Faraday’s electromagnetic rotation experiment demonstrated that a magnetic pole could be made to move continuously in a circle around a current-carrying wire.1

Building on the discovery by Hans Christian Ørsted that an electric current produces a magnetic field, Faraday realized that the resulting magnetic force was circular. By constructing an apparatus to isolate this effect, he successfully transformed electrical energy into mechanical energy, creating the world's first electric motor.1
