The solution with the lowest power, assembly and mass is to create an artificial charged particle ring (similar in form to a "radiation belt"), around the planet possibly formed by ejecting matter from one of the moons of Mars (in fashion similar to that that forms the Io-Jupiter plasma torus), but using electromagnetic and plasma waves to drive a net current in the ring (s) that results in an overall magnetic field.

Is it possible to create an artificial magnetosphere?
Unfortunately, we can't just recreate Earth's magnetic field on Mars. Our field is generated by a dynamo effect in Earth's core, where the convection of iron alloys generates Earth's geomagnetic field. The interior of Mars is smaller and cooler, and we can't simply “start it up” to create a magnetic dynamo.
How do you make a magnetosphere?
Earth's magnetosphere (magnetic field) is generated by a dynamo inside the planet. Dynamo theory is very complicated, but put simply the rotation of the earth produces rotating currents in the molten outer core which act like a giant electromagnet.
How can we create artificial magnetic field on Mars?
The team proposes using Phobos by ionizing particles from its surface, then accelerating them so they create a plasma torus along the orbit of Phobos. This would create a magnetic field strong enough to protect a terraformed Mars.

Can you create a magnetic field?
No, it is not possible to create magnetic waves without an electric field being present. Electric fields are created by electric charges. For instance, if you statically charged up a balloon by rubbing it on your hair, the balloon creates an electric field. Magnetic fields are created by magnets.
Is it possible to create an artificial atmosphere on Mars?
Science fiction has long dreamed of turning Mars into a second Earth, a place where humans could live without having to put on a space suit. The easiest way to do that would be to use carbon dioxide already on Mars to create a new atmosphere, but now researchers say that is impossible.
Can we terraform Mars without a magnetic field?
The planet's lack of a protective magnetic field means the solar wind will continue stripping its atmosphere and water, reverting our changes to Mars or constantly degrading them. To truly terraform Mars, we would need to fix its magnetic field—or lack thereof.
Is it scientifically possible to terraform Mars?
In a 1991 article published in the journal Current Science, scientist D. Balasubramanian explains “greenhouse warming,” which involves warming Mars by melting the planet's polar ice caps and releasing their stored carbon dioxide into the atmosphere. “Terraforming is not possible using present-day technology.”
How can Mars be a magnetosphere?
Mars doesn't have an intrinsic global magnetic field, but the solar wind directly interacts with the atmosphere of Mars, leading to the formation of a magnetosphere from magnetic field tubes. This poses challenges for mitigating solar radiation and retaining an atmosphere.
Can Earth lose its magnetic field?
Scientists don't know what drives pole reversal frequency, but it may be due to convection processes in Earth's mantle. During a pole reversal, the magnetic field weakens, but it doesn't completely disappear.
Why did Mars lose its magnetic field while Earth didn t?
Researchers believe that Mars once had a global magnetic field, like Earth's, but the iron-core dynamo that generated it shut down billions of years ago leaving behind only patches of magnetism due to magnetised minerals in the Martian crust.

So remarkably heating up the core to kick-start convection.
Can a planet be terraformed?
“Artificially creating an atmosphere may be possible, but it would be very expensive and challenging,” Khuller says. “Terraforming an entire planet will probably take a very long time — centuries or more.” But scientists have proposed other, more feasible ways we could make Mars habitable.
What creates Earth's magnetic field?
Generated by the motion of molten iron in Earth's core, the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun.
What would happen if we didn't have magnetosphere?
Without the magnetosphere, the relentless action of these solar particles could strip the Earth of its protective layers, which shield us from the Sun's ultraviolet radiation. It's clear that this magnetic bubble was key to helping Earth develop into a habitable planet.
Creating an Earth-like magnetic field on Mars is impossible
It’s not possible, at least judging by the current scientific progress, to create a magnetic field on Mars that’s similar to the one of Earth. But a new study shows that it’s possible to create an artificial magnetic field on the Red Planet.
