Hidden Portals in Earth's Magnetic Field

I'm wondering if portal is the right term to use. Seems like it's bound to be misinterpreted by some irresponsible reporter.

It will be interesting to see more details on how these bridges or threads (I'll avoid calling them portals) affect the magnetosphere, particularly if they are hidden. Are they responsible for previously unexpected behavior in the magnetosphere? Are they a navigation hazard for high orbiting craft?

On the other hand, the video and article seem to be reaching for views and the narration is terrible.

I wonder if you could somehow ride the field lines when these things snap, like some sort of cosmic railgun for firing things off into deep space.
