Inductor and Inductance Calculator

Inductors store energy in a magnetic field when electrical current flows through them. The inductance of an inductor depends on the number of turns, core material, and coil dimensions. Use this calculator to determine missing parameters based on given inputs.

Schematic Diagram and Formula

The inductance (L) is calculated using the formula:

L = (N² * r²) / (9r + 10l)
