A coil in a circuit refers to an inductor, which means that the wires are wound one by one, and the wires are insulated from each other. The insulating tube can be hollow or contain an iron core or a magnetic powder core, which is referred to as an inductor. Inductors can be divided into fixed inductors and variable inductors. Fixed inductor coils are referred to as inductors or coils. The purpose of a coil is that after power is applied, it can generate electromagnetic attraction, drive the armature of the magnetic circuit to attract, and cause the contacts to shift.
