A wire carries an I1 = 7.45-A current along the x-axis, and another wire carries an I2 = 5.00-A current along the y-axis, as shown in the figure below. What is the magnetic field at point P, located at x = 4.00 m, y = 3.00 m? magnitude      Use the expression for the magnetic field around a current-carrying wire to find the magnitude and direction of the magnetic field contribution from each of the two currents. µT direction              Two current-carrying wires lie along the axes in the x y coordinate plane. The wire along the x-axis carries current I1 in the +x-direction and lies on top of the wire along the y-axis, which carries current I2 in the +y-direction. Point P is in the first quadrant at (4.00, 3.00) m.
