Question

Comparing the mutual inductance M₁₂ of coil 1 with respect to coil 2 with the mutual inductance M₂₁ of coil 2 with respect to coil 1, it turns out that A)M₂₁ is always greater. B)M₁₂ > M₂₁. C)M₁₂ < or = M₂₁. D)M₁₂ = M₂₁. E)M₁₂ is always greater.

Quizplus · Accepted Answer

The mutual inductance between two coils is a property of the pair and is the same regardless of the order, so M₁₂ = M₂₁.
