10. An infinitely long current I flows on either side of a rectangular loop as shown in the figure at the left. Determine an expression for the total magnetic flux that penetrates the loop, in terms of the variables given. Hint: use the following result for the flux due to a single infinitely long line current, and assume that linearity holds for this problem. 11. A rod of mass 0.72 kg and radius 0.06 m rests on two parallel rails that are d = 0.12 m apart and L = 0.45 m long. The rod carries a current of I = 48 A. If it starts from rest, what is the speed of the rod as it leaves the rails if there is a uniform magnetic field of magnitude 0.24 T directed perpendicular to the rod and rails? Answer in units of m/s.
