alleryMutual inductance M between two coils is defined by EMF induced in coil 2:
AEMF₂ = M × (dI₁/dt)
BEMF₂ = M / I
CEMF₂ = M × Φ
DEMF₂ = M × I₁
Answer & Solution
Correct answer: A. EMF₂ = M × (dI₁/dt)
EMF₂ = -M dI₁/dt.
Mutual inductance M (henries) measures flux linkage between two coils per unit current. Reciprocal: M₁₂ = M₂₁.
