Ma Tian looked at the reward given by the system, and did not hesitate to start checking the paper - "A Special Electromagnetic Field Exploration".

This view is more than three hours, and it is enough to see the sky from the afternoon.

After reading it, even Ma Tian, who had seen the world, was shocked.

The paper given by the system this time is simply a hanging bomb!

To sum up this paper in one sentence, it can create a special electromagnetic field through a special electromagnetic field material - called "magnetic solid field" in the paper, this magnetic solid field has a strong gravitational and repulsive force, and can be well controlled!

That's right, you read that right, it is the gravitational force and the repulsive force at the same time, and the paper says that these two forces of stable aggregation are called "magnetosolid forces".

An example of an abstract point is magnetic levitation, but unlike magnetic levitation, which only has a repulsive force, it also has a strong gravitational force and can firmly fix the position between the two!

In the paper, the data shows that two pieces of 100 square centimeters of material, spaced 1 meter apart in a straight line, can produce a "magnetic force" of a staggering 10,000 kPa, equivalent to a force of 10 tons.

What is this concept? That is, if Ma Tian produced 100 square centimeters of this material, and then separated them by one meter and put ropes on both sides, it would take 10 tons of force to destroy the "magnetic force" between them! to pull them apart!

If this material is applied to the maglev train, the maglev train will not only have levitation power, but also have strong stability, and can speed at will!

No more worrying about throwing a turn out of a corner due to centrifugal force!

Traction can be achieved without even other energy sources, by changing the magneto-fixed field.

For example, the magnetic field in the track has been changing forward, and the maglev train is pulled forward as a towed object, as long as the magnetic field changes quickly, the maglev train behind can follow as fast as it is.

If the magneto-solid field transformation can reach the speed of light, then the maglev train will also tend to the speed of light!

The more Ma Tian thought about it, the more frightened he became, and in just a few moments, his mind thought of at least three or four powerful uses of this force, this "magnetic solid force", Ma Tian thought that it could be said that it was the fifth powerful force in addition to the four natural forces of the world that had been discovered so far!

Although it was already 6 o'clock in the evening, Ma Tian didn't want to eat it, and continued to look at the "Special Electromagnetic Field Material Production Manual", if Ma Tian was not wrong, this manual is the production of the corresponding magnetic solid field materials.

……

For three days, Ma Tian stayed in the laboratory for three days, and after three days, he came out of the laboratory and brought out a "ring toy".

The appearance of this ring toy is very simple, it is a disc base, and there is a hanging ring on it, and some toy factories may have produced this toy.

"Hua Lao, come and see my newly invented toy?" Ma Tian came to Hua Shuwen's office.

Now Huashuwen Jingcheng is not going back, and has a permanent office in Tianyu Xinghai, announcing that he has taken over the Tianyu Xinghai Hexagram Satellite Launch Base, as well as the Tianyu Xinghai Satellite Launch Plan.

This is the impact of Ma Tian's incident last time, that is, the state specially sent Hua Shuwen to keep an eye on Ma Tian to prevent Ma Tian from coming blindly.

It can also be perfunctory to other countries.

"Toys? Do you still have time to get toys? Hua Shuwen was a little puzzled, but he still looked up at the disc toy that Ma Tian was dragging in his hand.

"Isn't this magnetic levitation? What's famous? Hua Shuwen was a little interested, he naturally didn't think that Ma Tian was just getting something, especially if he had been in the laboratory for three days.

Ma Tian didn't explain too much, just put the disc toy in front of Hua Shuwen's table, and the disc base stretched out its machine feet and fixed it on the table by itself.

“？ Ma Tian, are you going to tear down my table? ”

"Hua Lao, don't worry, can you pull the ring above?" Ma Tian said with a smile.

“？” Hua Shuwen was full of question marks, but he still did it.

"Huh?" Hua Shuwen was stunned as soon as he got his hands on it, although he was almost 50 years old, he couldn't say that he was powerless, how could he pull a magnetic levitation ring and not be able to pull it a little? Even when he looked at it with the naked eye, the ring didn't even move?

He couldn't help but look at Ma Tian, only to see Ma Tian with an inexplicable smile on his face, as if he was looking at his old jokes.

Hua Shuwen was silent, and he didn't believe in evil, so he started to pull with his right hand, but he still looked at the ring and didn't move.

"Huh?" This time Hua Shuwen sensed that something was wrong, he let go of his right hand and began to touch the air under the ring, he wondered if there was a stealth fixation in the middle, causing him to not be able to pull the ring.

As a result, after touching for a long time, I didn't find it, and I didn't believe in evil and began to pull up the ring.

"Ma Tian boy, what are you here?"

After trying for a few minutes, Hua Shuwen finally gave up and asked about the initiator Ma Tian, this thing is a bit beyond his common sense, isn't the normal magnetic levitation a repulsive levitation thing, and it will be destabilized if you pull it out in parallel?

"Hua Lao, guess how hard it takes to pull this ring, of course, provided that the table can't move." Ma Tian didn't answer directly, but asked.

"How do I know? 100 kg? ”

"Huh? The pattern is smaller! Ma Tian shook his head.

"You kid sell me off? Can it still be a ton? Hua Shuwen scolded with a smile, and said a number at random, and his common sense told him that it was impossible.

"Huh? The pattern is still small! Ma Tian looked at Hua Shuwen, and the corners of his mouth continued to smile.

Now Hua Shuwen is not calm, as a big bull in the aviation industry, his physics and materials are definitely among the top in the world, this ring can not be pulled in the first place, it is already a bit contrary to the knowledge he has learned, and now he actually tells him that the force that can withstand a meal is still small?

"Ma Tian, what the hell is this? Don't you tell me that the ring and the disc move only by repulsion? Hua Shuwen's face was full of seriousness, and he realized that Ma Tian might have made something amazing.

Ma Tian didn't want to toss the old man anymore, so he said to himself: "Of course, it's not just repulsion, nor gravity, but a new force-magnetism!" ”

"Magnetism? What is this force? Hua Shuwen's eyes widened.

"As you can see, the power to hold the ring in the air through special blending. I can tell you that after my calculations, it would take about 7.8 tons of force to loosen the ring! Ma Tian said loudly.

"How much? 7.8 tons? At this moment, Hua Shuwen was completely shocked, and an expression of disbelief appeared on his face, "Ma Tian, are you sure you're not joking?" ”

"Nope!" Ma Tian nodded seriously and said.

He had tried it in the laboratory before, but there were no special instruments in the laboratory, and he could only test it with about 3 tons of force with the robotic arm, and the ring and disc were not moving.

According to the mathematical and physical formula he deduced, the rings and discs, which are 23 centimeters apart, need 7.8 tons of force to pull under the current environment. (End of chapter)
