Inductance of Air Core Inductor Calculator

Formula & Equations for inductance of air Core inductor Calculator

Inductance of an Air core coil inductor

L = (N² x d²) / (18d + 40l) … μH

Where,

• N = Number of turns,
• d = Inductor Coil Diameter,
• l = Inductor Coil Length.

Also;

The inductance of an air core coil inductor can be also calculated using the below equation.

L = (0.2 x d²x N²) / (3d + 9l =10b)

• L = Inductance (in μH)
• d = Diameter of the inductor coil (Inches)
• l = Length of the indutor coil (inches)
• b = Diameter of the coil winding wire (inches)
• N = Total turns of wire
