A wire loop confined in a plane is rotated in its open plane with some angular velocity. A uniform magnetic field exists in the region. Find the emf induced in the loop.

Text Solution

Verified by Experts

`i=V(Bxxl)`
`=vvBl. Cos theta`
`theta is the angle between normal to plane and B which is 90^(@)`
`Hence emf induced = 90^(@).`
`so, i=vBl cos 90^(@)=0.
