4A A straight conducting rod has mass m=40.0 g and length |=0.50 m. The rod is horizontally and can slide without friction on two vertical guides from insulating material. The ends of the rod are connected to an electromotive force source, so current flows intensity |=10.0 A. The whole system is inside a horizontal homogeneous magnetic field B, perpendicular to the plane defined by the ends of the bar and the verticals guides. What is the direction and magnitude of the magnetic field so that the conductor is in equilibrium?
