We prove a lower bound on the number of bound states for the case when B is of a compact support and the related flux is $N+ε, ε\in(0,1]$. In particular, there are at least N+1 bound states if B does not change sign. We also consider the situation where the magnetic field is due to a localized rotationally symmetric electric current vortex in the plane. In this case the flux is zero; there is a pair of bound states for a weak coupling, and higher orbital-momentum "spin-down" states appearing as the current strength increases.6 pages, LaTeX, to appear in Proceedings of QMath7, Prague 1997, published in the Birkhauser series "Operator Theory: Advances and Applications; the final version with a correction in Thm 2Mathematical PhysicsCondensed MatterQuantum Physicstext
