Question

A pair of parallel conducting rails that are L = 22 cm apart lies at right angles to a uniform magnetic field of 0.4 T directed into the page, as shown in the figure below. A R = 14 Ω resistor is connected across the rails. A conducting bar is moved to the right at 2 m/s across the rails.

1)What is the current in the resistor? (Express your answer to two significant figures.)

2)What is the magnetic force on the bar due to the induced current? (Express your answer to two significant figures.)
