What is the phenomenon where a changing magnetic current in a coil induces an electromotive force in an adjacent coil called?
A. Self-induction
B. Mutual induction✓ Correct Answer
C. Eddy current generation
D. Magnetic hysteresis
💡 Solution & Explanation
Mutual induction is the process whereby a varying electric current in one coil generates an electromotive force in a neighboring coil through electromagnetic coupling. Self-induction occurs when the changing flux affects the same coil carrying the current. This principle serves as the foundational operating mechanism for electrical transformers and induction coils.
