Question:

A conducting rod of mass m is in contact with two vertical conducting rails separated by a distance L, as shown in FIGURE 23-52. The entire system is immersed in a magnetic field of magnitude B pointing out of the page. Assuming the rod slides without friction,

(a) Describe the motion of the rod after it is released from rest.

(b) What is the direction of the induced current (clockwise or counterclockwise) in the circuit?
