The motional E.M.F depends upon:
Correct answer: D. All answers are correct
- A. Strength of magnetic field
- B. Speed of the conductor
- C. Length of conductor
- D. All answers are correct
Explanation
The factors on which motional emf depends are the magnetic field and velocity and length of the rod. Thus option D is the correct answer.

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.
