Abstract :
We model and simulate the microscopic electromagnetic fields induced by ion currents passing through nanochannels based on membrane currents data obtained by A. L. Hodgkin and A. F. Huxley in their experiments on squid giant axons. We find that compared with magnetic field, electric field affects ion motion much more considerably, and we further discuss the effect of such electric fields on the spread of Na+ concentration and the simulation shows that the field remarkably accelerates the diffusion process of ions left the channel.
