Turn the Universe

After nearly a month of violent bombing, Hanyu Xiaotian has basically accepted his fate that will accompany him with the knowledge of science and technology that has made him a little overwhelming in the next few years.

In fact, he had planned to graduate as soon as possible, but until today, a full month after he started school, these freshmen hadn't even seen any symbol of a rune!

This is very different from the purpose of Han Yu Xiaotian's coming here, how could he just leave so dingy?

Since I have chosen this place as my first stop in the world, I can't give up halfway, right?

What's more, after this period of "in-depth study", Han Yu Xiaotian unexpectedly discovered that this Xiaobai's scientific and technological knowledge has a subtle promotion of his magical powers!

"Today we are talking about cosmic magnetohydrodynamics. Magnetohydrodynamics is a subject that studies the interaction between conductive fluids and electromagnetic fields. It is a branch of theoretical astrophysics. Conductive fluids moving in electromagnetic fields are subject to Lorentz force on the one hand. , While also generating induced electromotive force.

The former causes the fluid motion to be affected by the electromagnetic field, and the latter causes the electromagnetic field to be affected by the fluid motion, thus forming a coupling between the flow field and the electromagnetic field.

Plasma can be regarded as a continuous medium under certain conditions, and magnetohydrodynamics is a macroscopic method for studying plasma theory. In fact, the development of magnetohydrodynamics has always promoted the development of plasma dynamics..."

A three-level rune master with a white beard is talking on the podium, and a pointer is continuously decomposing the multi-dimensional changes of the cosmic magnetic field fluid on the high-precision video screen, and the mouth is foaming.

"Most matter in the universe is in a state of gas and plasma. Inside stars, the gas is almost completely ionized. The gas in the interstellar space around hot stars is generally highly ionized. Magnetic fields are universal in the universe.

There are also magnetic fields on stars, and the magnetic field strength of the observed magnetic variable stars can reach tens of thousands of Gauss. The field strength of neutron stars is even greater, reaching 1012~1014 Gauss. There are also magnetic fields in interstellar space and intergalactic space. "

Finally, the master concluded: "Magnetohydrodynamics turbulence is often associated with the generation and maintenance of the magnetic field in the universe. The irregular motion of turbulence generally stretches the lines of magnetic force and increases the magnetic field. On the other hand, turbulence also increases the magnetic field. Of course, the magnetic field will also have an adverse effect on the turbulent motion.

Well, that's all for today's class, get out of class is over! "

Magnetic field~, cosmic turbulence~, increase loss~

A few words flickered in Hanyu Xiaotian's mind. During this short two-hour course, he suddenly felt that he had a new understanding and insight into the application of the magnetic field of the Heavenly Demon.

It turns out that the cooperation between the magnetic forces should be...the effect is the best; it turns out that to maximize the magnetic force, the loss of these turbulent forces should be reduced; it turns out that you need to pay attention to forming a perfect magnetic field. There are so many factors...

"Well, if I want to reduce the magnetic field of the celestial demon again and strengthen the power of the magnetic field, perhaps according to the master, it is not to reduce the magnetic lines, but to increase the encryption, and let them form a streamline vortex as much as possible. ....."

Han Yu Xiaotian kept thinking.

Obviously, this Magnetohydrodynamics class has given him a lot of inspiration, and he feels that he has even touched the key to the next stage of advancement of the magic magnetic field.
