The induced emf can be produced in a coil by
A. moving the coil with uniform speed inside uniform magnetic field
B. moving the coil with non uniform speed inside uniform magnetic field
C. rotating the coil inside the uniform magnetic field
D. changing the area of the coil inside the uniform magnetic field
Choose the correct answer from the options given below:
Answer: (C) C and D only
Translating a coil in a uniform field (at any speed) does not change the flux. Rotating it changes the angle, and changing its area changes the flux: C and D.
