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.
It explains how electrons are accelerated by an electron gun and then deflected by a magnetic field created by Helmholtz coils. The experiment measures the mass of an electron by analyzing the ...
