Two co planar concentric circular coils of radii a and b are placed in the y z plane such that the common center of the coils is origin a b A current i flows in the outer coil Now the inner coil is moved along the x axis with a constant speed v keeping its plane unchanged The emf induced in the inner coil is maximum at A a V B 3a V C D t 4 t a 2v
