A Conducting Bar Is Slid at Constant Velocity Toward the Positive

Multiple Choice

A conducting bar is slid at constant velocity toward the positive x direction, along two conducting rods connected across a resistor R, as shown in the figure here. The current generated by the apparatus increases if the following quantities increase except for

A) the speed of the bar.
B) the strength of the magnetic field.
C) the distance between the two conducting rods.
D) the resistance of the resistor.
E) All of the above increase the current generated by the apparatus; there are no exceptions.
