Question

29.33 A 0.250-m-long bar moves on parallel rails that are connected through a 6.00-Ohm resistor, as shown in Fig. E29.33, so the apparatus makes a complete circuit. You can ignore the resistance of the bar and rails. The circuit is in a uniform magnetic field B = 1.20 T that is directed out of the plane of the figure. At the instant when the induced current in the circuit is counterclockwise and equal to 1.75 A, what is the velocity of the bar (magnitude and direction)?
