Johannes Kepler first published his first two laws in 1609 in his Astronomia Nova [New Astronomy]. The title of this book is completely appropriate, as it is really the first book to attempt to study astronomy as a part of physics. In this post, I will examine certain aspects of the physics proposed by Kepler. It is important to remember that the publication date for the
Kepler's magnetic filament ideas might have been considered erroneous but it was a good guess. Are you familiar with the EU model (I had presumed you were - perhaps wrongly), specifically Clarage's recent take on solar filaments?
Awesome post, thanks. The idea of a magnet with poles at the surface and center is mind boggling. I wonder how Kepler represented that mathematically!
Simple answer: he didn't.

Actually, I did write a note on Michael Clarage's filaments substack post, even mentioning Kepler:
