magnetic clouds

[36grit]

I've read that the voyager has encounted magnetic fields at the edge of our solar system. I'm wondering if these magnetic fields might exist around all or most solar systems, and if they might or probably exist in denser quantites around the edge of a galaxie?

I wonder if the dynamics of these fields might create some kind of algorythmic structure of energy flow, and how or if the energy builds and releases in some fashion.
