[0002] The coil is made of a wire wound around an insulating tube in circles. The wires are insulated from each other, and the insulating tube can be hollow or contain an iron core or a magnetic powder core. The inductor is a device that works on the principle of electromagnetic induction. When current flows through a wire, a certain electromagnetic field will be generated around the wire, and the wire itself in this electromagnetic field will induce the wires within the range of this electromagnetic field. The effect on the wire itself that generates the electromagnetic field is called "self-inductance", that is, the changing current generated by the wire itself generates a changing magnetic field, and this magnetic field further affects the current in the wire; the effect on other wires within the range of this electromagnetic field is called "mutual inductance". The electrical characteristics of the inductor are opposite to those of the capacitor, "passing low frequencies and blocking high frequencies".
