The figure represents two long, straight, parallel wires carrying equal currents extending in a direction perpendicular to the page. The current in the right wire runs into the page and the current in the left runs out of the page.What is the direction of the magnetic field created by these wires at location a, b and c? (b is midway between the wires.)
