The change in flux linkages can be caused in which of the following ways ?
Correct answer: D. All of the above
- A. The flux is constant with respect to time and is stationary and the coil moves through it
- B. The coil is stationary with respect to flux and the flux varies in magnitude with respect to time
- C. Both the changes mentioned above occur together, i.e., the coil moves through a time varying field
- D. All of the above
Explanation
Flux linkages change either when a stationary coil moves through a magnetic field, when the flux varies around a stationary coil, or when both effects occur together. Each case produces induced e.m.f. according to Faraday's law.
