Electric machines function through the interaction between a rotating component, the rotor, and a non-rotating component, the stator. In an electric motor, the stator provides a magnetic field that dr

The Faraday disk was the first electric generator. The horseshoe-shaped magnet (A) created a magnetic field through the disk (D). When the disk was turned, this induced an electric current radially outward from the center toward the rim. The current flowed out through the sliding spring contact m, through the external circuit, and back into the center of the disk through the axle.
