[0002] Coil usually refers to a ring-shaped wire winding. The most common coil applications include: motors, inductors, transformers and loop antennas. The coil in the circuit refers to the inductor. It means that the wires are wound one by one, the wires are insulated from each other, and the insulating tube can be hollow or contain an iron core or a magnetic powder core, referred to as inductor. Inductor can be divided into fixed inductor and variable inductor. Fixed inductor coil is referred to as inductor or coil. It is represented by L, and the units are Henry, millihenry, microhenry, 1H=10^3mH=10^6uH.

[0003] There are many kinds of coils, and a magnetic field generating coil is one of them. For example, a Chinese patent discloses a magnetic field generating coil, and the patent number is: CN209933830U, which includes a circular or nearly circular coil wound by a wire, a shell for accommodating the coil, a terminal for connecting an external magnetic stimulator, a lead wire extending from the coil to the outside of the shell to connect with the terminal, and a handle fixed to the shell and the connection between the coil and the lead wire. The shell is consistent with the shape of the coil, and the surface of the coil is also covered with a sealed insulating layer.
