  We show that it is possible to simulate an anyon by a trapped atom which
possesses an induced electric dipole moment in the background of
electromagnetic fields with a specific configuration. The electromagnetic
fields we applied contain a magnetic and two electric fields. We find that when
the atom is cooled down to the limit of the negligibly small kinetic energy,
the atom behaves like an anyon because its angular momentum takes fractional
values. The fractional part of the angular momentum is determined by both the
magnetic and one of the electric fields. Roles two electromagnetic fields
played are analyzed.
