Background
An inductor is a circuit element that generates an electromotive force due to a change in a current passing therethrough, thereby resisting the change in the current. The most primitive inductor was the iron core coil of which faraday found electromagnetic induction in uk in 1831. The inductor is similar in structure to a transformer, but has only one winding, and generally consists of a bobbin, a winding, a shield, an encapsulating material, a magnetic core or an iron core and the like. If the inductor is in a state where no current is passing, it will try to block the current from flowing through it when the circuit is on; if the inductor is in a current passing state, the inductor will try to keep the current unchanged when the circuit is opened. Inductors are typically comprised of a bobbin, winding, shield, potting material, core or core, and the like.
