Abstract
The charges in live cells interact with or produce electric fields, which results in enormous dielectric responses, flexoelectricity, and related phenomena. Here we report on a contraction of schizosacchraoymces pombe (fission yeast) cells induced by magnetic fields, as observed using a phase sensitive projection image technique. Unlike electric fields, magnetic fields only act on moving charges. The observed behavior is quite remarkable, and may result from a contractile Lorentz force acting on diamagnetic screening currents. This would indicate extremely high intracellular charge mobilities. Besides, we observed a large electro - optical response from fission yeast cells.
