Acurrent carrying wire (with current i) travels to the right. a loop of length a and width b (a> b) is at a distance b above the wire. the sides of length a are parralell to the wire. two resistors (r1, r2) are placed on each side of length b. a conducting rod is pulled to the left at constant speed v along the sides of length a, perpendicular to the wire. what is the magnetic flux of each part of the loop as a function of time?
