Abstract

A scheme is evaluated to attempt noninvasive detection of small transient bioelectric currents, like those flowing in nerves, by measuring the Lorentz forces generated by pulsatile ionic currents when exposed to steady magnetic fields. The data suggest that dipole moments on the order of 10 nA-m in small objects would be detectable by this approach. Since a cross product relationship between the magnetic field and current dipole exists, current flow vector direction information is obtainable by manipulating the magnetic field direction.
