Get Price### Inductor Wikipedia, the free encyclopedia

An inductor, also called a coil or reactor, is a passive twoterminal electrical component which resists changes in electric current passing through it. It consists of a conductor such as a wire, usually wound into a coil. Energy is stored in a magnetic field in the coil as long as current flows. When the current flowing through an inductor changes, the timevarying magnetic field induces a
