About Inductance Calculation

What is Inductance & Its Calculator?

Inductance is the property of an electrical conductor to oppose a change in the electric current flowing through it. It is denoted by the symbol L and measured in Henries (H). An inductance calculator is a tool that helps engineers and hobbyists estimate the inductance value based on the physical parameters of a coil, such as its dimensions, number of turns, and core material.

Understanding and accurately calculating inductance is crucial for designing filters, oscillators, transformers, motors, and various radio frequency (RF) circuits. Different coil structures (e.g., single-layer, multi-layer) and core materials significantly affect the final inductance value.
