This is a pretty embarassing way to open this article:
NASA legitimately has a plan for this, and no it's not crazy, and no it doesn't involve restarting the core of a planet:

You just put a giant magnet in space at Mars' L1 Lagrange point (the orbital point that is stable between Mars and the sun), and then it will block the solar wind that strips Mars' atmosphere.
Otherwise cosmic rays etc are blocked and interrupted by the atmosphere, not the magnetosphere.
The confident dismissiveness of the author's tone on a subject that they are (clearly) not an expert in, let alone took the time to google, says all you really need to know about how much you should listen to them.
Well, that's a lot saner than nuking the poles.
Doesn't seem like we're near technical feasibility, though - how would you power such a massive magnet in space?
as masterspace noted NASA has actually given it some thought.

It also doesn't completely protect the entire planet just two critical points on the surface.
The linked article says the artificial magnetosphere would encompass the entire planet and points out this includes two critical places where the most atmosphere is lost.
So yes by virtue of it encompassing the whole planet it does cover those two places.. I suppose they wanted to specifically mention them
oh thank you for the correction I misread that bit it would seem
Indeed, "in the future" seems to be doing quite a lot of heavy lifting. As noted, 1-2 Tesla is a pretty powerful magnet - so you'd need a pretty big and powerful magnet.
That is certainly an important catch.
Just because people talk about something at one conference that doesn't make it real, feasible, happening, etc. As the actual people said, it's "fanciful". It's literally just people talking. It doesn't matter where they work.
that's what "some thought" means my guy
You're talking about the people who lowered a car from a rocket crane onto the surface of another planet, you can be thoughtfully critical, but their technical record has earned them a lot more than surface level dismissal.
