A conducting rod is free to move along 2 parallel conducting rails. On one end a resistor, R, connects the two rails which forms a circuit. The rails are oriented along the y axis of a coordinate system. There is a constant magnetic B aligned with the z axis making it perpendicular to the plane of the rails and rod. If the rod is given an initial velocity of vo, and hence a kinetic energy of m*vo2 /2, mathematically demonstrate that as the rod rounds to a stop in an infinite time the power lost in the resistor as heat is equal to the initial kinetic energy.

The loop consists of a single turn of flexible conducting wire that is wrapped around a flexible mount such that the dimensions of the rectangle can be changed. (Total length of the wire is not changed). As the edge length x is varied from approximately zero to its maximum value of approximately 4.0cm, the magnitude of the torque t on the loop changes. The maximum value of torque t is 4.8 * 10-8N m. What is the current in the loop?
