A rod of mass m and radius R rest on two parallel rails that are distance l apart and have a length L . The rod carries a current I ( in the direction shown ) and rolls along the rails without slipping. A uniform magnetic field B is directed perpendicular to the rod and the rails. If it starts from rest, wat is the speed of the rod as it leaves the rails ?

A vertical ring of radius r and resistance on R falls vertically. It is in contact with two vertical rails which are joined at the top. The rails are without friction and resistance. There is a horizontal uniform, magnetic field of magnitude B perpendicular to the plane of the ring and the rails. When the speed of the ring is v , the current in the section PQ is
