In the figure, current i-44.9 mA is set up in a loop having two radial lengths and two semicircles of radii a = 5.38 cm and b - 13.2 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 (b) (c) Number (d) Units Units
