Consider the physical system shown in the figure which consists of two long current- carrying wires. A 71 cm segment of each long wire is shown. 4 A wire 1 22 cm wire 2 11 cm a a. If the net magnetic field at point a is out of the page, is the force between the wires attractive or repulsive? Explain in 1-2 sentences. b. Calculate the current in wire 2 given that the magnetic field at point a is out of the page with a magnitude of 21 AT. c. Calculate the magnitude of the force exerted by wire 1 on wire 2
