(6%) Problem 4: The figure below shows two current carrying wires and the directions of the currents they carry. The wires carry the following currents: I = 7.2 A and I2 = 9.2 A. Wire 1 is at (0, 7.8) mm; wire 2 is at (15.9,0) mm; point P is at (15.9, 7.8) mm. y P 12 x 50% Part (a) What is the magnitude of the magnetic field at point P in teslas?
