The EMF does not depend on which of the following?
A. The magnetic field strength
B. The number of electrons in the magnetic field
C. The velocity of the wire in the field
D. The length of the wire in the magnetic field

Answer :

Answer:

Explanation:

When a wire of length L is moved with velocity v , perpendicular to magnetic field B , EMF will be produced at its two ends . EMF can be calculated with the help of following expression

EMF = BLv

As per this formula , EMF produced will not depend upon number of electrons in the magnetic field.

So B is the right choice.
