✦ Synopsis

The dynamic theory of helical vortices in a superconducting wire subjected to a longitudinal bias current and axial magnetic field has been developed. Two distinct regimes are identified: vanishing and spreading. The helix radius and the voltage induced by the helix motion are obtained as functions of time. In the presence of an AC current the jumps of the voltage are caused by the helix motion.
