Two very long wires are parallel to each other separated by a distance d.  The same current flows through each wire but in opposite directions.  See the arrows in the diagram.  Let I = 1 Amp and d = 0.1 meter.

a)  What is the direction of the net magnetic field due to the two, long wires in the space between the wires? Explain your answer.

b)  Calculate the magnitude of the net field at point P, which is half-way between the wires.

c)  Calculate the magnitude of the magnetic force per unit length due to wire #1 on #2.

d)  Determine the direction of the force calculated in part (c) and explain your answer.
