COMEDK · Physics · 22. Electromagnetic Induction
According to Faraday's law of electromagnetic induction an emf is induced in a coil, if
- A electric flux links with the coil
- B magnetic flux links with the coil
- C magnetic flux linked with the coil changes
- D electric flux linked with the coil changes
Answer & Solution
Correct Answer
(C) magnetic flux linked with the coil changes
Step-by-step Solution
Detailed explanation
According to the Faraday's law of electromagnetic induction, whenever the magnetic flux linked with a coil changes continuously with time, an emf is induced in the coil. Its magnitude is equal to the rate of change of magnetic flux i.e., \[ e=N \frac{d \phi}{d t} \] where, \(N\)…
