Query: N=2 superparticle near horizon of a magnetized Kerr black hole   Melvin-Kerr black hole represents a generalization of the Kerr black hole to
the case of a non-vanishing external magnetic field via the Harrison
transformation. Conformal mechanics related to the near horizon limit of such a
black hole configuration is studied and its unique N=2 supersymmetric extension
is constructed.
