Question

What are the factors affecting mutual inductance of a pair of coils?

Answer 1

Greater coil area presents less opposition to the formation ofmagnetic field flux, for a given amountof field force (amp-turns). COIL LENGTH: All other factors being equal, the longer the coil's length, the less inductance; the shorter the coil'slength, the greater the inductance

Answer 2

Explanation:

We observe that mutual inductance between two coils depends on the number of turns and magnetic flux which further depends on cross section area and permeability. Therefore, it can be concluded that mutual inductance depends on permeability of core, the number of their turns, cross sectional area of the common core.
