problem 33
Figure 30-52 shows a rod of length L = 10.0 cm that is forced to move at a constant speed v = 5.00 m/s along horizontal rails. The rod, rails, a connecting strip at the right form a conducting loop. The rod has a resistance of 0.4 Ohms; the rest of the loop has negligible resistance. A current I = 100 A through the long straight wire at a distance a = 10.0 mm from the loop sets up a (nonuniform) magnetic field through the loop. Find the emf and current through the loop. At what rate is thermal energy dissipated? What is the force on the wire?
It’s the same problem in the 7th ed. Ans 240 μV, so same answer. I didn’t check thee others yet.
