A 2 meters long conductor moves at right angles to a magnetic field of flux density 1 tesla with a velocity of 12.5 m/s. The induced e.m.f. in the conductor will be

he length of conductor is l=2 m

The magnetic field of flux density B=1 tesla

The velocity of the induce emf v= 12.5 m/sec

To find:

The induced emf in the conductor be.

Solution:

The induced emf formula is

E= v.B.l

Putting the above value

we get

E=12.5×1×2

E= 25 V

So the induce e.m.f in the conductor is  25 V
