Can we use paramagnetism to create a magnetic field on Mars?

AI Thread Summary
Mars lacks a magnetosphere, contributing to its thin atmosphere, unlike Earth, which has a significant magnetic field that protects it from solar wind. The presence of Iron (III) Oxide on Mars, which exhibits paramagnetism, raises the question of whether strong magnets could be used to create a magnetic field on the planet. However, the feasibility of deploying trillions of strong magnets is impractical. An alternative suggestion is to re-melt Mars' core, allowing the movement of ferromagnetic fluid to generate a magnetic field naturally. This approach highlights the differences in the physics behind Mars' early magnetic field compared to Earth's.

Well I must admit, when it comes to magnets I haven't a clue. I know that Mars has no magnetosphere and it's why it has such a thin atmosphere. The Earth's magnetosphere, if I understand right, is not very strong, but the Earth is a rather large magnet, so it's affect on solar wind extends far out into space.

The surface of Mars is abundant with Iron (III) Oxide, which exhibits paramagnetism (atoms align in an externally applied magnetic field, amplifying the overall strength of the magnetic field). Could we not strategically place very strong magnets over the surface of Mars and take advantage of paramagnetic effects to give Mars and magnetosphere?

And where are you going to get the trillions of strong magnets you need?
 
That's just silly. All you really need to do is re-melt Mars' core! The circulating ferromagnetic fluid will eventually create the field for you.
 
Mars' core could be "gooey" or even completely molten -- meaning that Mars' early Magnetic Field was powered by different Physics from Earth's.
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
