#3. (20 points) Three long current carrying wires were placed as shown in the figure. The directions of the currents are as seen in the figure and their magnitudes 13 = 20 A. are I, = 8 A, I, = 20 A and P. 8 cm (a) (5 points) Find the magnetic field at point P due to current I,. Give your result in vectorial form. (b) (5 points) Find the magnetic field at point P due to current /2. Give your result in vectorial form. (c) (5 points) Find the magnetic field at point P due to current I3. Give your result in vectorial form. (d) (2 points) Find the net magnetic field at point P due to currents 1,, 1, and 13? Give your result in vectorial form. (e) (3 points) Explain in detail how you found the directions of the magnetic fields generated by the three currents. #3.
