310 I0 X:0 X:d Two long parallel wires are separated by distance d, and carry current in the y direction. The wire at x=O carries current 3|0 in the positive y-direction while the wire at x=d carries a smaller current IO in the negative y-direction. (a) What is the direction ofthe force on the wire at x=0? What is the direction of the force on the wire at x=d? (b) Indicate the direction of the magnetic field created by each wire in each of the three regions: xd. You can show your answer by drawing appropriate X's and 0's of two different colors on a diagram like the one above, or alternatively make two copies of the diagram. (c) If we introduce a third parallel, current-carrying wire, where should it be placed if we want it to experience zero net magnetic force
