The figure below shows two current segments. The lower segment carries current iq = 0.56 A and includes a circular arc with radius 8.1 cm, angle 180°, and center point P. The upper segment carries current iz = 2i1 and includes a circular arc with radius 4.4 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 B for the indicated current directions? What are the (c) magnitude and (d) direction (into or otherwise of the page) of B ifi¡ is reversed? (a) Number i Units (b) into (c) Number i Units
