3) Calculate a magnetic field In the above figure, a current of 1.5 A flows to the right in the top wire and back to the left in the bottom wire. The pair go off effectively "to infinity" at the edge of the picture. The round part on the top wire is a semicircle. a) Calculate the contribution of the round part of the wire to the magnetic field at its center of curvature ("" in the figure). b) Calculate the contribution of the bottom wire to the magnetic field at the same point. c) Explain why the straight parts of the top wire do not contribute to the magnetic field at the same point. d) What is the total magnetic field at that point, and in what diretion does it point? 3) Calculate a magnetic field In the above figure, a current of 1.5 A flows to the right in the top wire and back to the left in the bottom wire.
