Part A The magnetic field of the brain has been measured to be approximately 3.0 × 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? Express your answer using two significant figures. Ο ΑΣΦ I = ? A
