Explain how changing magnetic flux linkage induces electromotive force (emf).
Model answer
What a good answer should say
- Changing magnetic flux linkage induces an electromotive force (emf) according to Faraday's law of electromagnetic induction.
- This law states that the induced emf in a circuit is directly proportional to the rate of change of magnetic flux linkage through the circuit.
Explanation
Why this works
This answer is strong because it directly references Faraday's law, which is fundamental to understanding electromagnetic induction. The question tests the student's ability to connect the concept of changing magnetic flux with the resulting emf, demonstrating their grasp of the underlying physics principles.
