Name: KS Problem 1: (30 pts, total) Two long conducting rails (with negligible resistance, length 1) are spaced a distance w apart and are connected on the right hand side by a resistor R. A uniform magnetic field of magnitude B is directed perpendicular to the paper and going into the page. An additional conducting rod makes contact with the metal rails on the left-hand side. You grab bold of the rod (using insulating gloves so as to not transfer charge to you) and move the rod to the right at a constant speed v. a) (12 pts.) Find the magnitude and direction of the induced current flowing through the rod. Justify your current direction choice! Aintu the page b) (10 pts.) Find the magnitude and direction of the force exerted by the magnetic field on the moving rod, due to the current flowing through it. F=ilBsino c) (8 pts. What is the rate at which you do work to keep the rod moving at constant speed v? How does it compare to power dissipated through the resistor? dw at = Power P: Vr = 1 ? R= B² (²1² , R R
