Problem 1 A conducting rod of length L is being pulled to the right along a set of frictionless conducting rails. An external force pulls the rod along at a constant speed v. The rod and rails sit in a uniform magnetic field B that points everywhere out of the page. The rails and rod form a closed electrical circuit with a resistor whose value is R. Derive an expression for the power dissipated in the resistor in terms of v, R, L, and B. Use RHR 1 and the concept of motional emf to show that a magnetic force is opposing the motion of the rod.
