I would appreciate more context.

Yeah... me to... this is... what am I watching?

A mechanical analogy, a model, a visual tool.  The spiral plunger is analogous to Bz.  Pushing down on the plunger is like negative Bz which makes a connection at the pole and transfers energy (though mechanical not magnetic) to the globe.  Pulling up on the plunger like as a positive Bz makes no connection at the pole and no energy is transferred.  A toy model and memory aid that negative Bz is needed to create the connection and energy transfer to spark aurora and geomagnetic storms.

Doesn’t load for me 😕

Yeah that's an animated gif.  Here is the longer version from YouTube:

In the model the downward push is turning/transforming into kinetic energy, akin to the Earth increasing its spin. I think a lot of the energy from the Sun is delivered to the poles and is reflected from the artic/Antarctic ice, or deflected off the magnetic sphere.

Perhaps put metallic streamers on your top-model and the light reflected from the streamers would be analogous to the Bz.

This is just my impression of it, but I understand what you are saying.
