How to Use Coil Inductance Calculator
You can easily use this Coil Inductance Calculator and calculate the coil inductance. First, provide the coil radius in cm. The calculator will automatically compute the cross sectional area after entering the coil radius. Next, input the solenoid length, number of turns, relative permeability (μr) of the core material, and the permeability of free space (μ₀), which is pre-filled with the default value of 1.26 × 10⁻⁶ H/m. After that select unit for output value to be shown from the dropdown menu. Once all required fields are filled, click the "Calculate Inductance" button to obtain the inductance value. The result will be displayed below in scientific notation for accuracy. If you need to reset the inputs, click the "Reset" button to clear all fields and restore default values.
Coil Inductance Formula
Inductance (L) = μrμ0N2A/l
Where,
- L is the inductance in Henries (H).
- N is the number of turns in the coil.
- μr is the relative permeability of the core material.
- μ0 is Permeability of free space (1.26×10−6 H/m)
- A is the cross-sectional area of the coil in square meters (m2)
- l is the length of the coil in meters (m).
