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 simplest generator consists of just a coil of wire and a bar magnet ... as this helped to concentrate the magnetic field.

Getting a magnetic field to ... of current regulation ICs. The coils can be made in house if necessary, with each winding getting about 800 turns of enameled wire. The rest of the circuit is ...

They are positioned with more of their surface area inside the magnetic field ... Casting) wire, hand-wound exactly eight times to create an innovative rectangular shape. The coils used in ...
