Abstract

The current-driven vortex motion in a resistively shunted long Josephson junction is calculated. It is shown that the force on the vortex exerted by an ac Josephson current or a bias current routinely assumed for studying Josephson transmission lines is a Lorentz force, whereas the driving force on the vortex acted by a transport dc Josephson current is a London force, which could have an expression apparently similar to that of a Lorentz force with an opposite sign. © 2007 American Institute of Physics.
