Please solve this question in details and explaination. Thanks so much in advance.

In the figure, current i = 62.2 mA is set up in a loop having two radial lengths and two semicircles of radii a = 5.08 cm and b = 10.7 cm with a common center P. What are the (a) magnitude and (b) direction (into or out of the page) of the magnetic field at P and the (c) magnitude and (d) direction (into or out of the page) of the loop's magnetic dipole moment? (a) Number Units (b) (c) Number Units (d)
