A) the strength of the magnetic field
B) the speed with which the magnet is moved
C) the number of turns is the coil
D) the resistance of the coil
E) the area of cross-section of the coil
Correct Answer: D
Solution :
Whenever a magnet is moved either towards or away from a conducting coil, the magnetic flux linked with the coil changes and therefore an emf is induced in the coil. The magnitude of induced emf \[e=-N\frac{d\phi }{dt}\] \[e=-N\frac{d\,(BA)}{dt}\] Time interval dt, depends on the speed with which the magnet is moved. Therefore, the induced emf is independent of the resistance of the coil.
