Problem 1. ( The magnetic field around the head has been measured to be approximately 3.0 x 10-8 G. Although the currents that cause this field are quite complicated, we can get a rough estimate of their size by modeling them as a single circular current loop 16 cm (the width of a typical head) in diameter. What is the current needed to produce such a field at the center of the loop? (1 gauss 1 x 10-4 T, o = 4 x 10-7 T.m/A)
