The figure below shows two current segments. The lower segment carries current i1 = 0.55 A and includes a circular arc with radius 5.0 cm, angle 180°, and center point P. The upper segment carries current i2 = 2i1 and includes a circular arc with radius 4.9 cm, angle 120°, and the same center point P. What are the (a) magnitude and (b) direction (into or otherwise of the page) of the net magnetic field Upper B Overscript right-arrow EndScripts for the indicated current directions? What are the (c) magnitude and (d) direction (into or otherwise of the page) of Upper B Overscript right-arrow EndScripts if i1 is reversed?
