Coil Inductance Calculator

Calc the inductance of a coil

$4.99 · Designed for iPad

Coil Inductance Calculator helps you quickly calculate the inductance of a coil of wire. Just enter the number of turns, loop diameter, wire diameter, and the permeability of the medium to get instant results. Features: • Easy input for number of turns, loop size, and wire thickness • Supports multiple measurement units for diameter values • Instant inductance calculation in henries (H) • Handy reference formulas included Formula: L = Inductance (H) N = Number of turns D = Loop diameter d = Wire diameter μ0 = Permeability of free space (4π×10⁻⁷) μr = Relative permeability 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. Thanks for your support!
