28.29 Two long, parallel wires are separated by a dis- tance of 0.400 m (Fig. E28.29). The currents ₁ and 2 have the directions shown. (a) Calculate the magnitude of the force ex- erted by each wire on a 1.20 m length of the other. Is the force attractive or repulsive? (b) Each 0.400 m 1₂2₂ = 2.00 A current is doubled, so that I becomes 10.0 A and 12 becomes 4.00 A. Now what is the magnitude of the force that each wire exerts on a 1.20 m length of the other?
