Questions
Figures (a) and (b) show a square loop of side a rotating about the given axes in a uniform magnetic field such that the field is perpendicular to the axis in both cases. Angular speed of rotation is both cases being the same,
detailed solution
Correct option is C
We know that the moment of inertia of a symmetrical planar body about any axis lying in its plane and passing through its centre is same. Further, angular velocity is also same in both cases. Thus, induced emf is also same.Similar Questions
An elasticized conducting band r is around a spherical balloon T (figure). Its plane passes through the center of the balloon. A uniform magnetic field of magnitude 0.04 T is directed perpendicular to the plane of the band. Air is let out of the balloon at 100 cm3s-1 at an instant when the radius of the balloon is 10 cm. The induced emf in the band is
