A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.
The film demonstrates an experiment using an apparatus to observe the behavior of electrons in a uniform magnetic field. It explains how electrons are accelerated by an electron gun and then ...
