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

e=no of pole*flux*speed*no of armature conductor

In a generator induced emf is proportional to speed hence if speed increses obviously emf increases.

E propotional to Speed.

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.

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

Sonam said:   1 decade ago
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.

According to ohm's law current and voltage are inversely proportional. So voltage decreases.
