So just how much of a magnetic field would be needed to protect Mars and the humans that might someday live on it? Surprisingly, the team writes that the force needed to deflect say, solar wind, is about the same as a regular fridge magnet. But they’d need to generate it over the entire planet, a substantial challenge.
The scientists suggested a few ways to pull it off. These include restarting and circulating Mars’ iron core, creating a continuous solid loop or loop of solid-state magnets, or using a chain of coupled sources with a controlled beam or a plasma torus — a big ring, basically — of charged particles with an artificial current. This means there are options that include hardware in locations as wide ranging as the Martian surface and Martian orbit.
While each option has pros and cons, the team concluded that reigniting Mars’ core is least feasible, and creating a plasma torus with blasted-off moon material would not significantly erode Mars’ satellites. That latter option also somewhat mimics the plasma torus created in Io’s orbit around Jupiter.
Needless to say, creating a magnetic field would require massive resources; the absolute bare minimum of power needed would be around is around 10¹⁷ joules, which was nearly the entire power consumption of all humans on Earth in 2020. That means we’ll likely need to employ nuclear fission reactors as a power source, which team speculates would likely be required for permanent colonization anyway.

Oh well that sounds easy. Let's do it tomorrow then.
I just plug a power strip into itself and everything works great.
They want to squeeze Mars to try and make it’s core molten ? LOL How do they know it already not molten but just Too far away from the Sun
The utter hubris. We can’t even unload container ships anymore, and we’re going to terraform Mars?
No need for a magnetic field - just throw a few GPS satellites up there and people will be able to get around.
We have gone from unbelievable technical lengths to prevent the introduction of ANY microorganism from earth into other planets (”do no harm”) to now thinking about how to create new magnetic fields around other planets to make them hospitable for earth organisms.
Nothing like consistency.
Their magnetic personalities should keep the cosmic rays and solar wind at bay.
Unbelievable, you have just discovered the source of perpetual energy!!!! Shhhhh...least keep it our secret until I can patent it! :^)
Just drill to the core of Mars and blow up about a hundred million nukes or so.
That’s all it takes from my random idea with no scientific thought behind it whatsoever.
Remember the Transform Mars by pumping CO2 into it’s atmosphere , so how must more CO2 can Mars take ,LOL
Gotta love theoretical physics.
Maybe get 'er done before lunch, even. These are probably the same 'scientists' who think that (for the first time in the earth's climate-change history) our entire planet is warming up because of charcoal grills & gas-powered leaf blowers...
Man-made global warming anyone?
Mars doesn't need a magnetic field, it needs a new atmosphere, 78 percent nitrogen, 22 percent oxygen. Both gases can be obtained in the outer solar system, and perhaps even closer. Once introduced, it will take 100,000 or more years for the solar wind to strip the entire thing, if that's even A) feasible and B) related to the magnetic field of the planet.
This might make Marvin very, very angry
How hard can it be?
