This invention discloses an assembly method of aluminum electrolytic rectifier DC bus-bar, especially to an indoor aluminum electrolytic rectifier DC bus-bar magnetic vortex defend solving method.

The result shows that in the presence of inhomogeneous magnetic field. the shear Alfvenwaves will be able to form localized vortex structures through their self-interactions.

These solutions belong to the intrinsic electromagnetic vortices, the corresponding magnetic field perturbations and the longitudinal current are continuous on the boundary of the vortex.
