Four long, parallel conductors carry equal currents of I = 6.20 A. The figure below is an end view of the conductors. The current direction is into the page at points A and B and out of the page at C and D. A x B(x l D (a) Calculate the magnitude of the magnetic field at point P, located at the center of the square of edge length l = 0.200 m. T (b) Determine the direction of the magnetic field at point P, located at the center of the square of edge length l to the left to the right upward downward into the page O out of the page = 0.200 m.
