Magnetic field of a nerve impulse: first measurements.

J P Wikswo, J P Barach, J A Freeman.   

Abstract

The magnetic field of the action potential from an isolated frog sciatic nerve was measured by a SQUID magnetometer with a novel room-temperature pickup coil. The 1.2 x 10(-10) tesla field was measured 1.3 millimeters from the nerve with a signal-to-noise ratio of 40 to 1.
