1.

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

Answer»

SOLUTION :`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.
