Query: Wormhole solutions in the presence of nonlinear Maxwell field   Generalizing of the Maxwell field to nonlinear electrodynamics theories, we
look for the magnetic solutions. In initial approximation these models give the
usual linear electrodynamics. We consider a suitable metric and investigate the
properties of the solutions. Also, we use the cut-and-paste method to construct
wormhole structure. We generalize the static solutions to rotating spacetime
and obtain conserved quantities.
