Question

(6 pts) 6. A conducting bar lies on frictionless rails. A resistor R is connected across the left-hand ends of the rails and all other resistance in the circuit is negligible. The whole apparatus is immersed in a uniform magnetic field that is directed out of the page. The bar is moving to the left with speed . Points a and b are at each end of the resistor, asg shown in the sketch. (a) points a and b are at the same potential b) point a is at higher potential than point b (c) point a is at lower potential than point b

Explanation / Answer

Here

when the bar moves to the left , the flux through the loop is decreasing the induced magnetic field will be out of plane

which makes induced current counterclockwise

as the current is from a to b

hence, the point a is at the higher potential than point b
