When the magnet is in motion relative to a coil, an induced e.m.f. is produced. It does not depend upon:
Correct answer: A. Resistance of the coil
- A. Resistance of the coil
- B. Pole strength of the pole
- C. Motion of the magnet
- D. Number of turns of the coil
Explanation
The explanation is given below:Option A Is correct according to the equation given below as induced emf only depends on the rate of change of flux and number of turns in the coil. It does not depend on the resistance of the coil. The induced current depends on the resistance and since the product of induced current and resistance is constant, emf induced is also independent of the resistance of the coil.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
