Inductor Calculator: Single and Multi-Layer Coil Inductance

This page provides information about inductor calculators, specifically focusing on inductance calculations. We’ll cover calculators for single-layer coils and multilayer, multi-row coil types. The equations and formulas used by these calculators are also explained below.

Inductor Calculator - Single Layer Coil

Here’s an example using the single layer coil inductor calculator:

EXAMPLE #1

• INPUTS:

  • LOOP DIAMETER = 10 inches
  • COIL LENGTH = 20 inches
  • NO. OF TURNS = 10

• OUTPUTS:

  • INDUCTANCE = 10.20408 µH
