What is an Inductor?​

An inductor is a passive device that stores magnetic energy. Any conductor carrying electric current exhibits inductive properties and can be considered an inductor. To enhance the inductive effect, practical inductors are typically cylindrical coils formed by winding a long wire, as shown below:

Physical Inductor Component

An inductor consists of a coil formed by winding a conductor. When an electric current passes through the coil, it generates magnetic flux and stores energy. The parameter that characterizes the ability of an inductor to generate magnetic flux and store magnetic energy is called inductance, denoted by L.
