The results consistently yield the mass of an electron as approximately 9.1 ... magnetic field, electron gun, Helmholtz coils, mass of electron, kinetic energy, deflection, circular motion ...
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.
