In the figure below, a long circular pipe with outside radius R = 3.2 cm carries a (uniformly distributed) current i = 5.80 mA into the page. A wire runs parallel to the pipe at a distance of 3.00R from center to center. Find the magnitude and direction of the current in the wire such that the net magnetic field at point P has the same magnitude as the net magnetic field at the center of the pipe but is in the opposite direction. magnitude direction MA into the page Wire O- R P.
