About Inductors
An inductor—also known as a coil, choke, or reactor—is a passive electrical component that stores energy in a magnetic field when current flows through it. When the current changes, the magnetic field varies, inducing a voltage in the wire (Faraday’s Law of Induction). By Lenz’s Law, this induced voltage opposes changes in current, which is why inductors play a key role in circuits.

Take the guesswork out of coil calculations with Coil Inductance Calculator—a simple, reliable tool for students, hobbyists, and professionals.
