Question

What is Dependence of Mutual Inductance?

Answer

Dependence of Mutual Inductance - (i) Number of turns (N₁, N₂) of both coils, (ii) Coefficient of self-inductances (L₁, L₂) of both the coils, (iii) Area of cross-section of coils, (iv) Magnetic permeability of medium between the coils (μ_r) or nature of material on which two coils are wound, (v) Coupling factor K between primary and secondary coils, (vi) Distance between two coils (As, d ↑ = M ↓), (vii) Orientation between primary and secondary coil (for 90° orientation, no flux relation i.e. M = 0)
