Ultra-Fast Moving Vortex in Superconductor (video) The Hebrew University of Jerusalem Share Print E-Mail Loading video... Caption This movie shows vortex dynamics driven by different currents (see meter at the bottom). At low currents (low drives), the vortices are stationary and appear as bright dots. At high currents (high drives) vortices move at 20 km/s and appear to this technique as a smeared line.
