In a 2013 episode of the show Breaking Bad, there is a scene in which Walter is going to steal a supply of methylamine from a train. The rails are a standard distance of 4 ft, 8.5 in. apart. Each rail can carry a current of 10 A and they'll carry current in opposite directions. A rail worker's toolbox sits near the tracks. The base of the toolbox is a 20 cm x 40 cm rectangle (with the 40 cm side parallel to the rails, but 10 cm away). To be safe, the edge, which is made of metal, is insulated from the center, so the base of this toolbox makes a simple rectangular loop, as shown. Take the total resistance of that loop to be R = 15 N. Because of some batteries left in an unfortunate arrangement in the toolbox, the toolbox loop is powered with ε = 9 V. R = 150 10 cm 1 M 40 cm 2 4 + ε = 9V 3 20 cm 4' 8.5" ¯¯¯¯¯¯¯¯¯¯¯ III a. What is the total magnetic force on the toolbox at the instant pictured? b. When calculating the net force, you likely didn't take into account the force that wire 2 exerts on wire 4. Why would this not change your answer?
