A conducting bar of length D pivoted at one end is rotating freely with an angular velocity in a uniform magnetic field B as shown below. The other and of the bar is in contact with a stationary conducting wire in the shape of a circle. There is a resistor R between the pivot point and the circular wire. The resistance of the bar and the circular wire are negligible. BO P @ R (a) [10 points] What is the induced current in the loop? (b) [5 points ] What is the direction of the induced current in the loop?
