Question

What may be the factors affecting the induced emf?​

Answer 1

Answer:

the factors affecting induced EMF are

1. number of turns

2. the rate of change of flux

i.e if speed of rotation is more the induced EMF is more, speed is less then induced EMF is less

hence,

E= -N∆phi/∆t

Answer 2

Answer:

Minimum things required to induce emf are conductor , flux and movement of conductor in magnetic field. From this equation it can be seen that induced emf depends upon flux density, effective length of conductor, velocity of conductor and angle between velocity direction and flux direction.
