What is the effect of increasing the number of turns in a coil on the induced emf when the magnetic flux linkage changes?.
- A.The induced emf decreases
- B.The induced emf remains the same
- C.The induced emf increases
- D.The induced emf becomes zero
Model answer
What a good answer should say
- The induced emf increases
Explanation
Why this works
Increasing the number of turns in a coil increases the total magnetic flux linkage. According to Faraday's law, the induced emf is proportional to the number of turns, so more turns result in a greater induced emf for the same rate of change of magnetic flux.
