How do you calculate the mutual inductance between two coils?

The formula to calculate the mutual inductance between two coils is given by:

M = (Ī¼ā * Nā * Nā * A) / L

where:

M is the mutual inductance in henries (H).

Ī¼ā is the permeability of free space, approximately 4Ļ x 10ā»ā· H/m.

Nā is the number of turns in the first coil.

Nā is the number of turns in the second coil.

A is the area of the overlapping region of the two coils in square meters.

L is the length of
