The resistance of the metal bar with a weight of 3 N and a length of 1.5 m is 10 Ω. The metal rod can move freely on the wires. The magnitude of the magnetic field in the region where the bar is located is 1.6 T and it is in the same plane and right to the circuit. Immediately after the key is closed; a) What is the acceleration of the rod? b) In which direction does the bar move?
