In Figure 4, a rod of length L=0.1 m is forced to move along horizontal rails at a constant speed v =5.00 m/s. The rod and rails form a conducting loop with the connecting strip at the right. The rod is known to have a resistance 0.4 92, rest of the loop has negligible resistance. The conducting loop is placed into a magnetic field generated by the long straight wire at distance a=0.01 m from the loop. Find the magnitude of the force that must be applied externally on the rod to make it moving with constant speed.

Question

Q4 . In Figure 4, a rod of length L=0.1 m is forced to move along horizontal rails at a constant speed v =5.00 m/s. The rod and rails form a conducting loop with the connecting strip at the right. The rod is known to have a resistance 0.4 92, rest of the loop has negligible resistance. The conducting loop is placed into a magnetic field generated by the long straight wire at distance a=0.01 m from the loop. Find the magnitude of the force that must be applied externally on the rod to make it moving with constant speed.

. In Figure 4, a rod of length L=0.1 m is forced to move along horizontal rails at a
Q4.
constant speed v =5.00 m/s. The rod and rails form a conducting loop with the connecting strip at the
right. The rod is known to have a resistance 0.4 2, whereas the rest of the loop has negligible
resistance. The conducting loop is placed into a magnetic field generated by the long straight wire at
distance a=0.01 m from the loop. Find the magnitude of the force that must be applied externally on
the rod to make it moving with constant speed.
