Magnetic Field of a Nerve Impulse: First Measurements
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 × 10-10 tesla field was measured 1.3 millimeters from the nerve with a signal-to-noise ratio of 40 to 1.
