A uniform magnetic field B exists in a vertical direction as shown in Fig.313. Find the emf induced in the loop if the loop is roated with a uniform angualr velocity ω about (a) an axis passing through the center and perpendicular to the plane of the loop. (b) the diameter.

A bar magnet is released from rest and starts falling through a metal ring as shown in fig A wire loop is suspended from a string that is attached to point P in the drawing. When released but in case (II) it has been cut through. discuss the motion of the magnet in both cases when it is above the ring and below the ring as well. consider ywo cases from left to right in case (I) the ring is solid all the way around the loop swings downward through a uniform magnetic field
