Question 27





Q27:Two long, parallel wires are attracted to each other by a force per unit length of mN/m. One wire carries a current of A to the right and is located along the line y = m. The second wire lies along the x axis. Determine the value of y for the line in the plane of the two wires along which the total magnetic field is zero.
