1. A conducting rod of length 0.1 m is pushed along a conducting rail through a constant magnetic field of strength 0.15 T. How fast in meters per second would the rod have to be moved in order to produce an emf of 3 V?

2. Taking the moving rod from the previous question and the result for the current, what force in N would an agent (e.g. a human hand) need to exert on the rod in order to balance the magnetic force on the rod and keep it moving at constant speed?

A conducting rod is pulled horizontally with constant force F= 3.40 N along a set of rails separated by d= 0.380 m. A uniform magnetic field B= 0.600 T is directed into the page. There is no friction between the rod and the rails, and the rod moves with constant velocity v= 4.80 m/s. Using Faraday's Law, calculate the induced emf around the loop in the figure that is caused by the changing flux. Assign clockwise to be the positive...
