  We consider an electron with an anomalous magnetic moment, g>2, confined to a
plane and interacting with a nonhomogeneous magnetic field B, and investigate
the corresponding Pauli Hamiltonian. 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 $N+\epsilon, \epsilon\in(0,1]$. 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.
