The magnitude of induced emf in a coil depends on the :
- A amount of magnetic flux linked with the coil
- B amount of electric flux linked with the coil
- C rate of change of magnetic flux linked with the coil
- D rate of change of electric flux linked with the coil
Answer & Solution
Correct Answer
(C) rate of change of magnetic flux linked with the coil
Step-by-step Solution
Detailed explanation
According to Faraday's Law of Electromagnetic Induction, the magnitude of the induced emf ( \(\varepsilon\) ) is directly proportional to the time rate of change of magnetic flux ( \(\Phi_B\) ) through the coil. This is represented mathematically by the formula:…
