When currents in wires run parallel, the wires attract due to the magnetic fields from the currents and the Lorentz force. The currents can also be ... contact Ricky Chu at ricky_chu AT sfu DOT ca.

We find that the Lorentz-force back-action can be so large that, in combination with complex nonlinear Josephson dynamics, it generates intrinsic self-sustained oscillations. The flux quantization ...
