A conducting rod OA of length l is rotated about its end O with an angular velocity `omega` in a uniform magnetic field directed perpendicualr to the rotation. Find the emf induced in the rod, between it's ends.

Text Solution

Verified by Experts

It is an example of motional emf where velocity of different points upon conductor are different,
so, `e= int de`
`= int Bv_(x)dx`
`= int B omega X dx`
`= (1)/(2) B omega t^(2)`
