The figure above shows an equal amount of current passing through two parallel wires. Point A is above the wires, Point B is midway between the two wires, and point C is below the wires. The current in the top wire is moving to the left and the current in the bottom wire is moving to the left. What is the direction of the resultant magnetic field due to both wires at points A, B, and C? A-in, B-out, C-in; A-in, B-zero, C-out; A-in, B-zero, C-in; A-out, B-zero, C-in; A-out, B-in, C-out.
