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.

Inductors, coils and chokes are passive devices that are designed to resist changes in current and store energy in the form of a magnetic field. In their simplest form, inductors consist of a wire ...

Magnetic field instruments are devices used to measure the magnetic field or flux around permanent magnets, coils, and electrical devices. They include meters, gauges, sensors, recorders, and other ...

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 ...
