Previously, people always said that the encounter with someone was a destined fate, and when the magnetic field appeared, everyone began to give this fate the "name of science", thinking that two people with similar magnetic fields would attract each other in the dark.
Conceptual diagram of the "magnetic field of the human body"
Of course, there is no scientific basis for this statement. However, the study of magnetic fields is indeed a matter of great concern to many scientists.
Previously, scientists used frogs to do experiments and put them into a strong magnetic field, thus obtaining an anti-gravity frog. So, what happens if you put people into a strong magnetic field? Will we also float like frogs?

As we all know, the earth is very special compared to other planets, such as we have liquid water, suitable temperature, etc., of course, the most important thing is that the earth has a "radiationproof coat", and a strong magnetic field can help us resist a lot of radiation from the universe.
However, the strength of the geomagnetic field is about 0.5 to 0.6 gauss, which is not a high value, and it is still relatively friendly to humans and earthly creatures.

After all, water is resistant to magnetism, and most organisms on Earth have a large number of water molecules in their bodies, in which case if the magnetic field is strong enough, then we can indeed float up. When scientist André Heim discovered the antimagnetic properties of water, he tried to experiment with living things. He wanted to see how the organism would behave when the magnetic field was strong enough.
So he put a frog into the experimental device, and the unknown frog actually levitated after entering, and kept spinning in the air. In this way, Andre Heim successfully used scientific experiments to obtain an "anti-gravity frog".

And this discovery made him very excited, because since he could let frogs float in a strong magnetic field, it meant that people with the same anti-magnetic properties could also levitate in a strong enough magnetic field. In this way, we may not have to leave the earth to experience the feeling of "weightlessness", but it is also difficult to control our actions in this environment.
So, can we create a strong magnetic field that allows people to achieve "anti-gravity"? If you put people into it, will people's health be affected by strong magnetic fields?

What happens when you put people in it?
The magnetic field strength that can first make frogs and other organisms suspended must be greater than 5T, and the concept of strong magnetic field has been constantly updated over the years. For example, a strong magnetic field can refer to a steady-state magnetic field with a maximum of 45T in scientific experiments, or it can refer to an 8T magnetic field generated by a superconducting magnet with an aperture that accommodates only one person for magnetic resonance imaging.
And the duration of the strong magnetic field varies, and the type also varies significantly. If the magnetic field lasts a long time and the value is constant, then this is called a steady-state strong magnetic field. On the other hand, if the duration is very short, it is a pulsed strong magnetic field.

However, no matter what kind of magnetic field, the current strength of the artificial magnetic field is not enough for people to achieve "anti-gravity" in it, and this kind of floating looks very interesting, in fact, the damage to the experimental organism itself is still relatively large.
So, what kind of damage will a strong magnetic field cause to the human body?
Magnetic fields are present around the magnet
According to a previous survey report by the Soviet Institute of Scientific Research, people working in environments with slightly higher magnetic field strength have significantly dilated blood vessels and significantly increased finger temperatures. Exposure to strong magnetic fields may cause decline and hormonal imbalances in central nervous system functions.
Of course, because the antimagnetism of the human body itself is derived from "cells", many scientists will focus on the primary exploration target on the cells and observe the performance of cells in strong magnetic fields.
Cells are the most basic building blocks of the human body
According to research, strong magnetic fields affect the morphology, direction, proliferation and apoptosis of cells, which ultimately affect the human body.
In terms of cell proliferation, multiple studies have shown that strong magnetic fields affect the proliferation of chondrocytes, nerve cells, and embryonic cells, which is unfavorable for humans. But at the same time, it also has a significant inhibitory effect on the proliferation of a variety of tumor cells, which makes scientists think that it may be rationally used in anti-cancer treatment in the future.
According to the data, in 1996, Raylman et al. found that the 7T strong magnetic field can slow down the proliferation of melanoma cells (HTB63), ovarian cancer cells (HTB77IP3) and lymphoma cell lines (CCL86) for 64 hours.

However, on the whole, the strong magnetic field is still relatively large in harm to the human body, so even if it is possible to create a magnetic field that supports the suspension of the human body, it is impossible to put people into it for testing. After all, life safety is still in the first place, even if you want to test, you must wear special protective equipment.
It is worth mentioning that scientists have been studying strong magnetic fields not just to achieve the boring thing of placing people in them and levitating. It is because the strong magnetic field plays an important role in discovering new phenomena and understanding new phenomena, and it has a certain use value in many fields.

Scientific application of strong magnetic fields
The first is condensed matter physics, such as semiconductor physics research and superconductor physics research, strong magnetic fields can provide a good research environment. For example, in the 1980s, people used strong magnetic field technology to discover integer and fractional quantum Hall effects in semiconductor two-dimensional electronic gas.
In the exploration of superconductivity, the magnetic field can effectively regulate the superconducting state, help people understand the characteristics of different superconducting states, and further understand the superconducting mechanism. According to the current research results, the auxiliary effect of the strong magnetic field is still very large.

Secondly, in terms of magnetic materials, the study of strong magnetic fields enriches the phase diagram, variable magnetism, and resistance of magnetic materials of magnetic materials.
Finally, strong magnetic fields have positive significance in chemistry, materials science, microgravity, life sciences, earth sciences and other aspects, such as nuclear magnetic resonance, which many people have done in hospitals, which has contributed to the study of strong magnetic fields.
Familiar MRI instruments
In short, from the current scientific field of strong magnetic field application, its development potential is still very large. And many countries are conducting strong magnetic field research, and the mainland has also developed a steady-state strong magnetic field experimental device.
It is worth mentioning that in addition to the strong magnetic field used in the experiment, some of the lower strength magnetic fields can be applied to magnetic therapy, which is still beneficial to the human body.

The Magical "Magnetic Therapy"
When we introduced the impact of strong magnetic fields on the human body in the previous article, we mentioned that magnetic fields affect the response of cells in various aspects of the human body. On the other hand, magnetic fields can also have positive biological effects. In this case, the magnetic field can be used to treat the disease, generally referred to as magnetic therapy.
Although the magnetic field has not been discovered by humans for a long time, the magnetic therapy on the mainland has a history of more than two thousand years, and it is recorded in the "History" and Shen Kuo's "Record of Forgetting", which is specially made of "magnets".
A wonderful product of nature – a natural magnet
The "Records of History" writes that "the King of Qi's attendants fell ill and refined the five stones to serve them", while the "Record of Forgetting" described the "medicine well" that was placed into the magnet.
However, it should be noted that the strength of magnetic therapy is strictly required, and the effect of treatment also varies from person to person. Therefore, at this stage, the use of magnetic therapy to treat diseases is still relatively small, if the future of medicine can really be used, then it can indeed bring good news to human health.

In addition, human beings should also take precautions and consider the problem of "artificial magnetic field". Because whether it is a future interstellar migration or a legendary magnetic pole reversal, it is necessary for the "artificial magnetic field" to mature as soon as possible.
After all, our flesh is indeed too fragile compared to the harsh cosmic radiation, and once the protection of the magnetic field is lost, then the body will be invisibly bombarded by radiation.
If we can develop a device that maintains the required magnetic field everywhere, even if it is not a strong magnetic field, it will be a kind of adaptation to the cosmic environment.
The Earth's magnetic field protects us from solar radiation
Of course, before this, human beings may need to solve the mystery of the Earth's magnetic field, although the scientific community now generally accepts the self-excited motor theory, but it is difficult to say what new discoveries will be made when we actually reach the core of the Earth.
