  We investigate the stability of the wormhole of the
Mors-Thorne-Ellis-Bronnikov type. In our model the matter inside it consists of
a radial magnetic field and an ideal phantom-fluid. Properties of the matter
are described in section 1, 2 and 3 of this paper. We consider spherical
perturbations only and find examples of the stable wormholes against these
perturbations.
