Question

Which property of two coils describes a change in current in one coil inducing an emf in the other?

विकल्प

• Permeability of the core medium

• Relative orientation

• Self-inductance

• Mutual inductance

Answer 1

Mutual inductance is the property of two coils by which a change in current in one induces an emf in the other. It describes the interaction between the coils, rather than the self-inductance of one coil.
