In a sense it can. Scientists have used magnets as sources of high-pressure and high-temperature fluid to generate both heat and electricity. However, the two are not closely related — electricity, in contrast to heat, is actually generated through movement. The main advantages of magnetic fields include high precision and versatility, and because it can be generated at a number of different temperatures, it is highly versatile.
Could such a thing occur in our Universe?
As far as we can tell, no. Magnetic fields are relatively weak — much less powerful than they are in the Earth’s core; very weak even for low-temperature gases in the outer reaches of the Galaxy.
Could such a thing already happen?

Well, on Earth the magnetism you feel in your hair and toes is probably due to the rotation of the Earth around its axis. As I have mentioned before, rotating around the north pole is pretty far away from the center of gravity so the energy needed to produce high-pressure fluids is small. That’s why you’re probably not seeing high-pressure air at the edge of the Earth. And there’s nothing like a big magnet field in the upper atmosphere to make that happen — a magnet can produce a large amount of heat, but it won’t create large enough magnetic fields to start something from nothing.
What is a magnet field?
Well, a magnet field is basically the energy of a magnetic field when viewed from the distance.
Can we produce it here on Earth?

As a matter of fact, we have found that we can. Scientists in Switzerland have developed a unique way of creating a magnetic field in the upper atmosphere. In the process they have created a magnetic field in the upper atmosphere, and this has been able to drive some very specific and extremely precise devices – the so-called magnetars.
What could these devices do?
In principle, in the case of those magnetars, they will be capable of generating electricity. What is needed to accomplish that is a magnetic field, and magnetic fields are the key component of the magnetars. The researchers are currently working on making this magnetic field as dense as possible through a superconducting material, which can act as a conduit for the flow of electric current.
