1. The problem statement, all variables and given/known data In the following diagram, the brown metallic conductor rod is given a slight push to the left. The black lines are all conducting wires, with the entire setup placed in a perpendicular B-field. Ignore friction. What will happen? 1) The rod slowly come to a stop? 2) The rod continues to move at constant speed? 3) The rod comes to a stop and reverses direction?

The attempt at a solution 1) I think this should be the answer, as kinetic energy has to be converted to electrical current (heating of the wires). The motion has got to die down. However, I cannot identify the retardation force that acts on the rod which is necessary for the motion to stop. 2) I don't think it's gonna move forever as argued above. 3) I seriously doubt this man. Intuition, somehow.
