Coil inductance is a measure of the ability of a coil of wire to store energy in a magnetic field. The inductance of a coil can be calculated using the following tool given below.
Coil Inductance Calculator
Inductance: H
Coil Inductance Calculating Formula
L = (N^2 * (mu_r) * A) / l
Where:
- L is the inductance in henries (H)
- N is the number of turns in the coil
- mu_r is the relative permeability of the core material
- A is the cross-sectional area of the coil in square meters (m^2)
- l is the length of the coil in meters (m)
The calculator is designed to calculate the inductance of a coil based on user inputs. To determine the inductance, users are typically required to provide information such as the number of turns, core material, and dimensions of the coil.
The provided formula is specifically applicable to single-layer air-core solenoid coils. It’s important to note that different types of coils, such as multi-layer or toroidal coils, may have different formulas for calculating inductance. The calculator assumes the core material to be either iron or air, and the relative permeability is adjusted accordingly.
