Assume a nerve of 0.50 m in length is stimulated and sends electrical impulses to the brain. along this section of nerve the velocity of the signal is around 0.40 m/s. how long does a signal take to travel the length of the nerve? assuming the charge traveling through the nerve to be that of 100.0 electrons, what would be the current traveling through the nerve? what would be the magnetic field strength 0.01x10 m away from the nerve? what would the maximum force generated by the current through the nerve be at that same distance?
