Suppose the 14-Acurrent in the straight wire in Figure
Chapter 22, Problem 82(choose chapter or problem)
Suppose the 14-Acurrent in the straight wire in Figure 2246 is reversed in direction, but the current in the loop is unchanged. (a) Calculate the magnitude and direction of the net force acting on the loop. (b) If the loop is extended in the horizontal direction, so that it is 1.0 m high and 2.0 m wide, does the net force exerted on the loop increase or decrease? By what factor? Explain. (c) If, instead, the loop is extended in the vertical direction, so it is 2.0 m high and 1.0 m wide, does the net force exerted on the loop increase or decrease? Explain.
