28.31 BIO Currents in the Brain. The magnetic field around the head has been measured to be approximately 3.0 pT. Although the cur- rents that cause this field are quite complicated, we can get a rough esti- mate 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?
