Chapter Seventy-Eight: The Landslide

There is only one factor that can make time stand still and the meter fails: the magnetic field effect!

I looked at my surroundings, at the mountains and at the special geographical structures, and the climatic conditions that formed something special, inexplicably invisible.

Perhaps, in the space that we cannot see with the naked eye, there is some kind of "magnetic field effect." ”

The so-called "magnetic field effect" is simply defined as a magnetic field in space that can generate magnetic force.

The magnetic field is a special and intangible substance, and if there is a magnetic field, there must be a magnet. There is a magnetic field around the magnet, and the interaction between the magnets is mediated by the magnetic field.

An electric current, a moving charge, a magnet, or a special form of matter stored in the space around the changing electric field, which is not visible to the naked eye.

Since the magnetism of a magnet is derived from an electric current, which is the movement of an electric charge, a magnetic field is generated by a moving electric charge or a changing electric field.

The basic characteristic of a magnetic field is that it exerts a force on the moving charge in it. This is where the magnetic field exerts on the electric current, the force or moment on the magnet.

Modern theories, on the other hand, state that magnetic force is a relativistic effect of the electric field force.

Similar to an electric field, a magnetic field is a vector field that is continuously distributed over a certain spatial area. The basic physical quantity that describes the magnetic field is the magnetic induction intensity vector b, which can also be illustrated by magnetic inductance lines.

However, as a vector field, the nature of the magnetic field is quite different from that of the electric field.

The magnetic field produced by a moving charge or a changing electric field, or the total magnetic field of the sum of the two, is a vector field with passive spin.

Lines of force are closed families of curves that do not break or cross. In other words, in the magnetic field, there is no source for zài to emit magnetic field lines, nor is there a tail for zài to converge magnetic field lines. The closure of the magnetic field lines indicates that the loop integral along the magnetic field lines is not zero. That is, the magnetic field has a rotation field instead of a potential field (a conservative field), and there is no scalar function similar to the electric potential.

Magnetic induction intensity: the number of magnetic field lines perpendicular to the direction of the magnetic field lines, also known as the density of the magnetic field lines, also known as the "magnetic flux density".

Direction of magnetic field: The north pole of the small magnetic needle is specified, and the direction of the magnetic field force at a point in the magnetic field is the direction of the electromagnetic field.

Speaking of which, I suddenly remembered when I was in school. The physics teacher did a real yàn: a real yàn made with a magnet and a small pile of iron filings, and that lesson mainly talked about magnetic induction lines.

It was that class that made me see the world of our world, as well as space and matter that cannot be seen with the naked eye.

Magnetic Induction Lines: Draw some curves in the magnetic field so that the tangent direction of any point on the curve is the same as the direction of the magnetic field at that point, these curves are called "magnetic field lines:".

The magnetic field lines are closed curves that specify the direction in which the north pole of the small magnetic needle points to the direction of the magnetic field lines. The magnetic field lines around the magnet come out from the n pole and enter the s pole, and the magnetic field lines inside the magnet go from the s pole to the n pole.

A long time ago, I didn't know why magnets were marked with "n" and "s". Afterward. You don't know what physics really means.

The electromagnetic field is the medium of electromagnetic action and is a unified whole. Electric and magnetic fields are two sides of it that are closely related and interdependent. A changing electric field produces a magnetic field, a changing magnetic field produces an electric field, and a changing electromagnetic field propagates in space in the form of waves.

Electromagnetic waves propagate at a finite speed, have exchangeable energy and momentum, the interaction between electromagnetic waves and physical objects, the mutual transformation of electromagnetic waves and particles, etc., all prove that electromagnetic fields are objectively existing in matter. It's "special". It's just that there is no static mass.

The magnetic phenomenon is one of the earliest physical phenomena recognized by mankind, and the compass is a major invention in ancient China.

The magnetic field is widely existent. Earth, stars (e.g., the Sun), galaxies (e.g., the Milky Way), planets, moons, and interstellar and intergalactic space all have magnetic fields.

In order to understand and explain many of these physical phenomena and processes, the magnetic field is an important factor.

In modern science and technology and human life, magnetic fields can be encountered everywhere: generators, electric motors, transformers, telegraphs, telephones, radios, accelerators, thermonuclear fusion devices, electromagnetic measuring instruments, and so on. All of them are related to magnetic phenomena.

Even in the human body, along with life activities, a weak magnetic field is generated in some tissues and organs.

According to scientific research, the magnetic level of the Earth is opposite to the geographical poles. Moreover, in different zones and locations of the planet. The magnetic field is also different.

Judging from the current situation, we should be in a position where we have such a magnetic field of power. It is this magnetic field that affects the failure of our watches and other instruments.

At the moment, I can't care about that much. Only by sending another signal flare can we know whether Qian Cheng has received our signal or not?

The big man saw that the geographical environment here is special, and the failure of our meters and instruments. Coupled with the fact that they themselves have witnessed the passage of time, there is no longer any reason to stop me from firing flares.

I didn't care about the three-seven-twenty-one, and pointed the flare gun that I had just loaded at the sky, and pulled the trigger at once.

With a bright "squeak" sound and a dazzling white light, a long white silver snake slid into the sky. Since there was no external force, the signal flare sent out "soared up to 90,000 miles" and suddenly rose to a very high height.

After reaching a certain height, he dragged his long tail and slid down in a curve.

There is such height and brightness, and in this environment where there is no obstruction of sight. I believe that even the blind man should be able to see it this time. In addition, it is already evening, and the light is even brighter and dazzling.

If Qian Chengzai didn't react or respond as he should this time, then it means that he has indeed encountered some unavoidable difficulties or dangers.

If he doesn't come back, then there's a good chance it's ......

I didn't dare to think about it any longer, so I could only shake my head and not let myself think about it. The more troubled I feel in my heart, the more I have to force myself to think in a good direction.

It was at this moment that suddenly, I heard a loud "click". Before I could react, I felt my feet shake. This shaking almost shook me off my head.

Since I had just looked at the sky, my eyes still had traces of that white light. At this time, it has not recovered all of a sudden, and it is not clear at all. I just wanted to take a closer look at the situation and ask the others what was going on, but there was another shaking under my feet.

Before I could ask, I heard the old ghost shouting, "Everyone, be careful, it's a landslide!" (To be continued......)
