  We classify certain integrable (both classical and quantum) generalisations
of Dirac magnetic monopole on topological sphere $S^2$ with constant magnetic
field, completing the previous local results by Ferapontov, Sayles and Veselov.
  We show that there are two integrable families of such generalisations with
integrals, which are quadratic in momenta. The first family corresponds to the
classical Clebsch systems, which can be interpreted as Dirac magnetic monopole
in harmonic electric field. The second family is new and can be written in
terms of elliptic functions on sphere $S^2$ with very special metrics.
