The human nervous system is an electric system. In particular, our brains produce a mag- netic field of approximately B = 3pF. The currents responsible for this field are rather complicated, and not easy to map. Let us, however, estimate the size of theses currents. Model the brain’s electric network as a single circuit. Estimate the size of this circuit by measuring your head’s circumference, and compute the current in your brain
