Wires 1 and 2 are very long, stationary, and carry a uniform 150-A current. An 80 cm segment of a third long wire has a mass of 5 g and is placed a perpendicular distance a = 12 cm away from wires 1 and 2. It is observed that wire 3 hovers in the air at rest due to gravitational and magnetic forces. wire 1 O a. What must be the current directions in wires 2 and wire 3 to create this equilibrium? Explain your reasoning in 1-2 sentences. a b. Calculate the magnitude and direction of the net magnetic field produced by wires 1 and 2, at the wire 3 location of wire 3. O a c. Calculate the current in wire 3 that maintains this equilibrium. a one of a newcull baision wire 2
