Needed to produce such a field at the center of the loop

Reference no: EM13538930

The magnetic field of the brain has been measured to be approximately 3.0 x 10^-12 T. 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 current is needed to produce such a field at the center of the loop?
