Two long, parallel wires are separated by a distance of 0.400 m. The currents 11 and I2 have the directions shown. 5.00 A 0.400 m 2.00 A (a) Calculate the magnitude of the force exerted by each wire on a 1.2 m length of the other. Is the force attractive or repulsive? attractive O repulsive (b) Each current is quartered, so that I1 becomes 1.25 A and I2 becomes 0.50 A. Now what is the magnitude of the force that each wire exerts on a 1.2 m length of the other?
