Magnetic field due to current carrying semicircular arcs.

The problem states:

Two semicircular arcs have radii R2 = 7.80 cm and R1 = 3.15 cm, carry current i = 0.281 A, and share the same center of curvature C. What are the (a) magnitude and (b) direction (into or out of the page) of the net magnetic field?


Solution Summary

The two semicircular arcs are concentric and with different radii form a current carrying loop. Magnetic field at the center is calculated.
