Please solve this question in detail. Thanks so much in advance.

The figure below shows two current segments. The lower segment carries current i1 = 0.62 A and includes a circular arc with radius 5.2 cm, angle 180%, and center point P. The upper segment carries current i2 = 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 if i, is reversed? (a) Number Units (b) (c) Number i Units v (d)
