A flat tape of width b = 0.5 cm made of a type II superconductor in a mixed state is placed in a magnetic field B = 10 T, perpendicular to the surface of the tape and much greater than the value of the first critical field. A current I = 10 A flows through the tape without dissipation. The vortices held by superconductor defects are motionless. Calculate the force F acting on a separate vortex from the side of crystal defects. Assume that the current is distributed uniformly over the sample, and that the vortex structure is created by others, independent of
