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.
