Coil Inductance Calculator
iOS Universel / Utilitaires
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.
