Let us consider the conductor which is moved in between the magnetic poles of the magnet. After some time we increase its moving speed in between the poles, then we will found that the conductor experiences more force in it. Because when we increase the speed of moving conductor then it experience more and more forces (emf).

It can also be derived from the formula,

e=B*L*V.

where e is the induced emf in the conductor when the conductor moves perpendicular to the field.

L is the length of the conductor.
V is the velocity of conductor.

And hence e is proportional to the speed of conductor.

According to faraday's 2nd law of electromagnetic induction magnitude of induced emf in conductor directly proportional to rate of changes of flux linkages to conductor. So when speed of conductor is increased rate of change of flux linkages also changed.

When the speed of conductor moving in presence of magnetic field increases, the number of magnetic lines of force cut by it increases and hence the induced voltage increase.

We know that:

eb = flux*Z*N*P/(60*A).

Hence, eb directly proportional to the speed (N). So as speed increases induced voltage will increase.

When the speed of conductor increases, the flux interact to conductor also increases so that the induced emf is increases in the conductor.

Due to magnetic field flux is produced, if flux increase means induced emf is increased. The flux is directly proportional to induced emf.

Speed of conductor is directly proportional to induced voltage.

So when magnetic field is increased induced voltage also increase.

Speed of conductor is directly proportional to induced voltage.

So when magnetic field is increased induced voltage also increase.

When a voltage is an increase, magnetic flux is produced. So conductor is a move in the magnetic field.
