On stability of a new model of wormhole
  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.
