In Fig. the bar AC has a mass of 50 g. It slides frictionlessly on the metal strips 40 cm apart at the edges of the incline. A current I flows through these strips and the bar, as shown. There is a magnetic field |Bx|=0.02T directed in the -y direction. How much must I be if the rod is to remain motionless? Neglect the slight overhang of the rod.

The figure below Shows two long metal rails placed horizontally and parallel to each other at a separation i. A uniform magnetic field b exists in the vertically downward direction. A wire of mass m can slide on the rails. The rails are connected to a constant current source which drives a current I in the circuirt. The friction coefficient between the rails and the wire is μ. (a) What should be the minimum value of μ which can prevent the wire from sliding on the rails? (b) Describe the motion of the wire if the value of μ is half the value found in the previous part.
