Two straight conducting rails form a right angle where their ends are joined. A conducting bar in contact with the rails starts at the vertex at time t = 0 and moves with constant velocity v along them as shown in Fig. A magnetic field `vec(B)` is directed into the page. the induced emf in the circuit at any time t is proportional to

A conducting rod, with a resistor of resistance R. is pulled with constant speed v on a smooth conducting rail as shown in figure. A constant magnetic field vecB is directed into the page. If the speed of the bar is doubled, by what factor does the rate of heat dissipation across the resistance R change?

The two conducting rails are placed perpendicular to each other, such that their ends are joined as shown in figure. A conducting bar is now placed over the rails and start moving with constant velocity v starting from the vertex at time t = 0.
