Question:

Figure 23-42 shows a zero-resistance rod sliding to the right on two zero-resistance rails separated by the distance L = 0.500 m. The rails are connected by a 10.0-Î© resistor, and the entire system is in a uniform magnetic field with a magnitude of 0.750 T.

(a) Find the speed at which the bar must be moved to produce a current of 0.175 A in the resistor.

(b) Would your answer to part (a) change if the bar was moving to the left instead of to the right? Explain.
