A rectangular loop is moving parallel to a long wire carrying current `i` with a velocity `v`. Find the emf induced in the loop (Fig. 3.68) if its nearest end is at a distance a from the wire. Draw equivalent electrical diagram.

Explanation

`emf=0`
`(mu_(0)iv)/(2pi)ln((1+b)/a)`
`(mu_(0)iv)/(2pi)ln((1+b)/a)`
