The strongest magnetic field in the universe

The finding has been possible thanks to data from the Chinese Insight-HXMT satellite and the work of Chinese and German scientists, it is a field of more than 1600 million teslas. This is not only the strongest magnetic field measured directly to date, but it is also the first detection of an electron cyclotron absorption line in an ultraluminous x-ray source, to put it more simply, a cyclotron is a type of a particle accelerator, but in nature the lines in a magnetic field can also accelerate particles producing great energy, that energy can be released in the form of powerful x-rays and those x-rays are what the satellite can ultimately detect.

In this way the power of the magnetic field can be calculated and this process has allowed a direct measurement of the magnetic field of the surface of the neutron star called GRO J1008-57, this neutron star belongs to a very specific subtype is a pulsar growing x-rays, as a pulsar it emits powerful rays of electromagnetic radiation that periodically reach the earth, but luckily it is very far away, this neutron star is about 22 thousand light years from us.

But since a magnetic field of such power is so powerful, although it may seem strange to you, the earth's magnetic field is ridiculously small compared to that of this neutron star, the earth has 30-60 microtesla, it is actually a little less than the typical a fridge magnet, although here size does matter and on a large scale the earth's magnetic field is enough to protect us.

The large MRI equipment in hospitals reaches up to 3 tesla, a respectable figure that is also reached by some neodymium industrial magnets, whose intensity is capable of erasing credit cards from a distance.

The large hadron collider uses a 4 key magnetic field in order to drive the particles and make them collide, but it is after 10 teslas when strange things start to happen, for example, andre geim won the nobel prize for physics In 2010, but ten years earlier, together with his colleague Konstantin Novoselov, he won the Ig Nobel, which is the anti-Nobel or Novel Prize for the absurd, since it rewards the craziest research. They won it for creating a 17-key magnetic field with which they managed to levitate a frog, it is believed that conscious they could levitate a human.

We haven't gotten that far as the largest artificial magnetic field created to date is 45 keys, which wouldn't happen even with more power is something we've seen in the movies, they strip the iron out of the blood and that's that the magnetic properties of iron change depending on where you are. Human beings have between 3.5 to 4 grams of iron in our body, more than half is in hemoglobin, which, when oxygenated, becomes day Magnetic, this means that it repels magnetic fields and if we add to this that the water in our body is also diamagnetic, the result is that in the face of a powerful magnetic field our body would repel it and this is the explanation that we could levitate the same thing that it did the body of the floating frog, but if we keep increasing the power things can get very ugly.

It is not very clear, among other things because we have never been able to carry out experiments at such a power, but it is suspected that between 10,000 and 100,000 Tesla the atoms begin to act strangely and a person subjected to a magnetic field of that intensity could melt. or disintegrate and we are still talking about up to 100,000 teslas. The news neutron star is 16 thousand times more powerful, the physical phenomena that can occur in its environment can be simply amazing and surely deadly for humans.
