Two current carrying straight wires AB and CD are kept one above the other, and a magnetic needle is kept between and at the same distance from both wires at Pas shown in the figure. Discuss the direction of magnetic field at point P. What happens if the polarity of the cell "CT, is reversed. (Assume that same amount of current passes through the two wires).
