Coil circuit is the inductor. Is the guiding line of one to one up each otheraround, wire insulation, and insulation pipe can be hollow, can also containiron or magnetic powder core, referred to as the inductance. The inductancecan be divided into fixed and variable inductance inductance inductance coil,inductance coil short or fixed. With L said, unit (H), Henry Henry (mH),Wahenry (uH), 1H=10^3mH=10^6uH.
