    "abstract": "We study a spin-1/2 charged particle with gyromagnetic factor g\u003e2 moving in a\nplane threaded by a magnetic flux tube. We prove that, if the magnetic field\n(i) has radial symmetry, (ii) has compact support and (iii) does not change\nsign, there is at least one bound state for each angular momentum l in the\ninterval [0,v], where v (assumed positive) is the total magnetic flux in units\nof the quantum of flux.",
