The characteristic torus structure accompanying an electron or the exemplary earth may be contemplated as two rotating gears manifest in 3 & 4-D space.
From there, one may begin to draw their own conclusions.
The north pole exit of the field swings around its parent system to enter the south pole.
Bisecting the system at the equator leaves you with an expanding system on top and a contracting system on the bottom, conceivable as matter and antimatter (white hole and black hole?), meeting in the middle and generating a continuous explosion which emerges as a 4-D expanding material system (In this case - earth).

A top view presents an expanding system.
A bottom view presents a contracting system.
Perspective:

There is a strong implication of Dirac's anti-matter meeting conventional matter with the resulting explosion constituting the entire magnetic and material system.

One interpretation is we're working with Dirac's otherwise (seemingly) elusive 'anti-matter' and it's role in the sustaining of any system generating or otherwise accompanied by a magnetic field - from electrons, to planets and stars.

Top-north is the outgoing magnetic field, bottom-south is the incoming; they meet in the middle at 'zero point'; at the interior center of the earth.

Consider a self-sustaining system of expansion here, with the 4-D earth omnidirectionally accelerating at the interior of the considered magnetic field.

Note the structure of Riemannian geometry constituting the ingoing and outgoing magnetic fields.

Other interpretations of these proposals about the issued system are invited.

Parallel universes in a Unified Field?
Meshing and rotation of two gears, each causing the other to revolve in the opposite direction, while doing this in harmony - two gears, reciprocally supportive opposite spins; two different portions of the (micro-macro) universe: side by side.
