A circular loop has a small bead which can slide on it without friction. The radius of the loop is r. Keeping the loop vertically it is rotated about a vertical diameter at a constant angular speed `omega`. What is the value of angle `theta`, when the bead is in dynamic equilibrium ?

A circular loop is kept perpendicular to a uniform magnetic field. Loop is rotated about its diameter with constant angular velocity.

A very small circular loop of radius a is initially (at t = 0) coplaner and concentric with a much larger fixed circular loop of radius b. A constant I flows in the larger loop. The smaller loop is rotated with a constant angular speed omega about the common diameter. The emf induced in the smaller loop as a function of time t is
