A 20 cm copper rod has a mass of 0.05 kg. If this rod is placed in a magnetic field with magnitude 0.6 T that points into the page while suspended in the air by two wires such that a current can flow through the copper rod as shown in the figure below, then what is the magnitude of the minimal electric current needed to overcome the weight of the rod?
