Question

a vertical rod of length l is moved with velocity v toward east. the vertical component of earth magnetic field is B and angle od dip is Theta. the induced emf in rod​

Answer 1

Answer:

The answer will be Blvcotθ

Explanation:

According to the problem the rod is having the length of l

and the velocity of v towards the direction of east

The magnetic field is B here.

Let the  induced emf of the rod is e

we know that   e = Blv

Now it is given that the magnetic field is created vertically,

Therefore the vertical component of the magnetic field is Bsinθ

   e =   Bsinθ x l x v cosθ

        =Blvcotθ
