Motional e.m.f induced in a coil is dependent on?
Correct answer: D. All of these
- A. Magnetic field
- B. Orientation
- C. Length
- D. All of these
Explanation
The factors on which 'Motional emf' depends are nothing but, the 'magnetic field, velocity, and length of the rod'.

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.
