This page focuses on calculating inductance for common configurations such as solenoids, toroids, and straight wires. How to Calculate Inductance. Inductance is calculated based on the geometry of the conductor and the magnetic permeability of the material within or around it.
This tool is designed to calculate the inductance of a coil of wire given the length of the coil, the number of turns, the loop radius, and the permeability of the core material.
This tool is designed to calculate the inductance of a length of wire given its diameter and length. Note that self-inductance of a wire is often not measured since it is only a part of a circuit's loop. To use this calculator, just enter the diameter and length of the wire.
This single-layer coil inductance calculator is an interactive online tool specifically designed to calculate the inductance value of a single coil of thin round-wire based on the coils loop inductance value. Electric inductance is usually represented by the letter L, and is expressed in Henrys (H).
Use this online calculator to determine the inductance of single-layer and multilayer air-core coils. Both metric and English units of measurement are supported.
Using this formula, the inductance of a 1 meter circumference loop of 14 gauge wire is. 1.12 μH; for 16 gauge wire it's 1.17 μH; and for 18 gauge wire it's 1.21 μH. Note the weak dependence of inductance on wire diameter, due to the natural log in the expression.
Calculate how many turns of wire must be wrapped around a hollow, non-magnetic (air) core 2 cm in diameter and 10 cm in length in order to create an inductance of 22 mH. You may use the permeability of free space (μ 0 ) for the μ value of the air core.
