A metal crossbar of mass m=1kg rides on a parallel pair of long
horizontal conducting rails separated by a distance L=1m and
connected to a device that supplies constant current I=1A to the
circuit. The rails are frictionless but tilted upward so that they
make an angle ?=30 with the horizontal. The magnetic field is
directed vertically downward. What minimum value of B is needed to
keep the bar from sliding down the rails? (Hint: consider the
gravity of the bar and the normal force of the rails).
