"Iron powder is sprayed to verify the magnetic field. After all, directly observing the magnetic field is an extremely difficult thing to do, and it is not accurate. However, the magnetic field can be easily observed through the extremely fine iron filings, and it is helpful to judge the strength of the magnetic field. Li Yuzhang saw the confused expressions of several people around him, so he explained.

In this virtual real room, I saw iron powder like a mist suddenly spraying out, filling the entire room. In an instant, several outsiders tried to shut their mouths. The fine iron powder is like the flying flour.

"Haha......" Seeing the appearance of several people, some of the experts in the research room began to laugh.

"Several, just breathe at ease, this is the virtual real room. It's just 100% projection of the other side, and it's all light and shadow. Seeing the appearance of several people, Li Yuzhang kindly reminded this.

Oh...... The four of them blushed a lot.

But it's no wonder that the simulation technology here is more advanced than the outside, and it is understandable that it is a real environment that makes people think that it is a real environment.

With the spraying of iron filings, a large amount of fine iron powder is magnetized in the air, forming thin lines that are weaker than a hair, and they are supported in the air out of thin air, as if a three-dimensional lantern-like network grows in the air.

"Look, compared to an electromagnet, this magnetic field is empty in the middle."

Sure enough, under the guidance of Li Yuzhang, the four of them found that in a blank area about one meter near the sphere, there was almost no iron powder.

Without waiting for these people to ask, Li Yuzhang began to explain: "In fact, the reason is very simple, that is, liquid sodium metal also has its own magnetic field in rotation, and the two magnetic fields cancel each other, which has become the current situation." Of course, we are still studying this mechanism, and we don't have a clue yet.

Normally, magnetic fields will cross each other, just like water ripples; But the magnetic fields here cancel each other out, as if they disappeared out of thin air.

But I believe that once this phenomenon is thoroughly studied, it will bring us great benefits. First of all, I don't need to use this huge, bloated, energy-intensive, and dangerous magnetic field generator. This thing, because there is a large amount of liquid metal sodium that rotates at high speed, even if it uses the new materials unique to the master company, it still cannot guarantee 100% safety.

Okay, so let's move on to the second test, which is the protection against charged particles.

According to existing research, cosmic radiation, solar storms, etc., the main components, and even the most common harmful components, are charged particles. That's why we use lasers to test protection.

The first step is the normal sunlight intensity. ”

In the meantime, the magnetic field generator has been restarted, and the iron filings have been carried away by the wind.

A ray of light hits a magnetic field; However, this light does not shine directly on the magnetic field generator, but is distorted as if the light enters the water and is refracted. But this time, you saw something more beautiful than refraction.

When the light hits the magnetic field, it instantly begins to scatter radioactively, like ink dripping into water, and the charged particles are deflected under the action of the magnetic field, and only a small amount of mild light hits the surface of the generator. Most of them form a beautiful halo in the magnetic field, like the aurora of the earth. There are also two faint rays of light that are ejected from the poles of the generator, and a small amount of light spreads through the magnetic field to the rear of the generator.

At the same time, the colorful colors of the generator also envelop the generator, bringing a dreamlike beauty.

"It's beautiful!" The four spectators were stunned by the beauty in front of them.

What is even more surprising is the researchers, especially Li Yuzhang. "Big discovery, big discovery! The ability to protect against this magnetic field is more than we can imagine! And, I think I'm seeing another application of magnetic fields!

Fast, increase the brightness, with ten times the intensity of sunlight! ”

Ten times the intensity of sunlight still does not penetrate the magnetic field, and the beautiful light response is even more beautiful.

100 quilts!

It still hasn't penetrated the magnetic field, but the current magnetic field generator seems to have been transformed into a jewel, and it is dazzling. That's the light that is separated by the magnetic field. There were also two bright single rays of light, erupting from the poles with scorching heat.

"I think I saw another laser cannon technology! This would be a terrifying technology, and it would be able to be combined with a magnetic field generator. ”

Next, the field of electric currents of different intensities was experimented, and even a low-intensity solar magnetic storm was simulated. And all the tests have shown that this one device is enough to protect the safety of the space shuttle near the Earth's orbit. The energy consumption is a bit large, especially in the case of resisting solar magnetic storms, and the energy consumption exceeds the energy consumption of 5.6 million kWh.

"It's a good technology, it's really good for protecting the fragile space shuttle for long expeditions in the sky. That is, the energy consumption is a bit large! Liu Haibo is very excited, the master company has solved such a problem. However, energy consumption is a new and increasing problem! In space, the status of energy is definitely the first place.

"Ahem!" Li Yuzhang was very dissatisfied with the pickiness of these guys, "In terms of batteries, the company is tackling key problems, and the third-generation battery technology should be soon." ”

"Hehe, then I'll be relieved!" Liu Haibo smiled heartlessly.

"Alright, come with me and I'll show you the most advanced magnetic field generator, which is a tiny device that can be implanted in a helmet as a protective device for spacesuits. It's a new gift for your expedition. With it, you will be able to work safely away from the Earth's magnetic field without worrying about the unpredictable radiation in the universe. ”

"That's a good idea!" Liu Haibo rubbed his hands with a look of anticipation. And even Li Canglan, who was relatively quiet next to him, was the same. As an astronaut, I understand the dangers of space radiation all too well. Why does ultraviolet light have a germicidal effect? That's the power of radiation! And the radiation in space is many times more powerful than ultraviolet rays, and if there is no protection, it can easily penetrate a steel plate with a thickness of ten centimeters, and it will not be weakened too much. Powerful radiation can cause DNA mutations, causing unpredictable crises.

After layers of inspection, I came to a real yàn room that was 100 meters deeper underground; However, even here, the advanced technology can only be viewed in the safe room of holographic projection. Because although this extremely advanced magnetic field generating device is good, it is also more dangerous and has the characteristics of being difficult to control.

Li Yuzhang took the initiative to introduce: "This magnetic field generating device imitates Jupiter's magnetic field. Jupiter has the most powerful ordered magnetic field in the solar system, and its magnetic field can extend beyond Saturn's orbit, and its magnetic field is more than 20,000 times stronger than that of Earth. But it is well known that Jupiter is a gaseous planet, and according to existing theoretical calculations, Jupiter does not have a solid core.

And only recently has this principle been theoretically resolved. That is, it is believed that in the core of Jupiter, there is a high-speed rotating and changing hydrogen atomic matter.

At pressures more than 150 times greater than the Earth's core, hydrogen is compressed to the limit and mutates into a substance with metallic properties, which we call 'metallic hydrogen', which has far more properties than iron in the creation of magnetic fields.

Because, it can rotate around itself. And now we're working on this technology.

However, the actual conditions are extremely harsh, and it is the use of high pressure and more than 3,000 laser irradiation to maintain such pressure; In the real environment, human beings themselves are inaccessible. But according to the current progress of research and development, within half a year, we will hopefully apply it to spacesuits. ”

"With this weapon, space exploration is worry-free!" Bangs Haibo's eyes lit up. As for the practical application, Liu Haibo has never been worried, the R&D strength of the master company is unimaginable to the world!
