Pb thin film sample and the experimental set-up. a 3D representation of a 10 × 5 µm2 AFM scan of the sample of 75 nm-thick Pb film patterned into a 10 µm-wide strip with a 5.7 µm wide constriction. Indicated are the directions of the applied magnetic field B a, current I, the Lorentz force acting on vortices F L, and the screening (Meissner) current density J M that is maximal along the edges. b SEM image of the same sample with corresponding distribution of the Meissner current J M(x) across the construction in absence of vortices and applied current. Scale bar is 2 µm
