A very long wire carrying current I is bent into the shape shown in the diagram. Apply the general result obtained in class from the Biot-Savart Law, B = mu_0I/4pi r(cos theta_1 - cos theta_2), to find the net magnetic field B, magnitude and direction, at point P. Show all your work in detail: very specifically show what are theta_1 and theta_2 for each segment of the wire. Simplify the answer. Use extra pages if needed.
