PS: The so-called magnetic field refers to the space where magnetic force acts. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 The info magnetic field is one of the basic forms of matter existence, which exists in the space around the magnet, the space around the moving charge, and the space around the current. The most common phenomenon in magnetic fields is the mutual attraction or repulsion of two magnetic objects, so the interaction between magnets is carried out by magnetic fields. The magnetic field will also produce a force on the energized conductor, indicating that the magnetic field has the nature of force, and when the energized conductor moves within the magnetic field, the magnetic field force will do work on the energized conductor, indicating that the magnetic field has energy. These manifestations illustrate the materiality of the magnetic field.

The so-called magnetic field refers to the space where there is a magnetic force. The magnetic field is one of the basic forms of existence of matter, and it exists in the space around the magnet, the space around the moving charge, and the space around the electric current.

The magnetic field will also produce a force on the energized conductor, indicating that the magnetic field has the nature of force, and when the energized conductor moves within the magnetic field, the magnetic field force will do work on the energized conductor, indicating that the magnetic field has energy.

1. Type of magnetic field

A constant magnetic field is also known as a static magnetic field, while an alternating magnetic field, a pulsating magnetic field, and a pulsed magnetic field belong to the dynamic magnetic field. A magnetic field that is equal or approximately equal in strength throughout the space is called a homogeneous magnetic field, otherwise it is called a non-uniform magnetic field. The farther away from the surface of the magnetic pole, the weaker the magnetic field becomes, and the magnetic field strength changes gradually.

(1) Constant magnetic field

A magnetic field that remains constant in strength and direction is called a constant magnetic field or a constant magnetic field, such as a magnetic field produced by a ferromagnetic sheet and an electromagnet that is passed through direct current.

(2) Alternating magnetic field

A magnetic field in which the strength and direction of the magnetic field changes regularly, such as the magnetic field generated by the power frequency magnetic therapy machine and the heteropolar rotating magnetic therapy machine.

(3) Pulsating magnetic field

A magnetic field in which the strength of the magnetic field changes regularly without changing the direction of the magnetic field. Like a polar rotating magnetic therapy device, a magnetic field generated by a pulsating DC electromagnet.

(4) Pulsed magnetic field

An intermittent oscillator is used to generate an intermittent pulse current, and this current is passed into the coil of the electromagnet to generate a pulsed magnetic field of various shapes. Pulsed magnetic fields are characterized by the intermittent occurrence of magnetic fields. The frequency of change, waveform, and peak value of the magnetic field can be adjusted as needed.

2. The influence of magnetic radiation in nature on brain dreams

In nature, there are geomagnetic and a large number of cosmic space material rays as well as solar magnetic storm radiation waves. These magnetic waves can have an irritating effect on the human brain and organs. These magnetic waves have a promoting effect on the growth of organisms, and at the same time, there is a certain intrinsic correlation between the human body and the magnetic field. The universe itself is a powerful magnetic field, and without the strong magnetic field of the universe, there would be no synthesis of biological cells in nature, and the creatures on the earth would not exist. Most of the hallucinations in human dreams are caused by space magnetic radiation, and powerful magnetic wave radiation can also cause significant harm to human beings, and can also cause the human nuclear magnetic resonance effect in space. Many strange phenomena in nature are due to the force of a strong magnetic field. It can cause the failure of the carrier pigeon to distinguish the geographical location, the error of human directionality, and the nightmare association of the human brain.

Have you ever heard of haunted houses and ghost lands? In these areas, people have a series of nightmares in which hallucinations, horrors, panics, delusions, and other factors are entangled with death. The strong ray particle waves in space can form the breaking of the molecular bonds of the human body or objects, the invisible cracks of clothing, the superficial scars of the human skin, and the spontaneous combustion without open flames.

If a person falls asleep in an area with a strong magnetic field, it can produce a worse state of dream association. The nightmares that humans have at night also have an associative factor during the day. If you enter an extremely terrifying area during the day (in fact, there is no such thing as a terrifying place in the world, it is the human mind that is at work. It's just a psychological effect), once it's time to sleep at night, your brain's active nervous system will bring you into dreamy associations and recreate terrifying scenes of time and space. Thus forming the human over-belief in dreams.

A young man and one of his companions went hunting in the mountains, unaware of the presence of a strong geomagnetic field in this area (in fact, it is better to say that it is more powerful magnetite). Night falls. The two hunters drifted off to sleep. One of them couldn't sleep after tossing and turning, recalling what he had seen and heard during the day. Unconsciously, I gradually fell asleep. In his sleep, he entered a large complex of buildings alone, dilapidated and dilapidated. The ruined walls are broken, and there is a bleak and terrifying scenery everywhere. From time to time, there was a wolf howl, which was terrifyingly quiet, and I felt that there was an invisible figure following me, and my heart was pounding all the time. Could it be that the ghosts of the world's legends are right in front of you? I'm so scared! Thinking about it, a gray-white figure suddenly flashed in front of him, jumping and suddenly disappearing. Damn! The soul was frightened, he was terrified, he turned around and ran, but his limbs were weak, and he couldn't run no matter how he ran. I saw a white-haired female ghost with fangs and claws, green fangs, and a long tongue suddenly appeared in front of him, scared to death! He was so scared that he said, "Damn! Mom", the female ghost was still scratching his face and body. It doesn't matter if he is shocked, he is so anxious that he shouts for help! Shouting and shouting, he suddenly woke up. At this time, his heart was still pounding. With this shout, he woke up his companion next to him. The companion poked him in the hand and said, "Hey! Wake up! What's wrong with you? So, he rubbed his misty eyes and said, "My mother! It's scary! Somehow, there was a female ghost chasing me, and she scratched me with her claws and covered in blood. "Hey! I see, are you having a nightmare? You scream so loudly, can I not wake up? I also stabbed you with my hand. Said the companion next to him. The two of them went back to sleep while talking.

Everyone has heard of the supernatural incident in Fengmen Village, Jiaozuo, Henan Province, China! This is the same as the above-mentioned dream causes. Hallucinations in human dreams caused by the natural environment are common. Magnetic radiation is a double-edged sword, which can benefit or harm humans. The human perspective of Roentgen rays, the imaging mechanism of nuclear magnetic resonance, the treatment of infrared diseases, long-distance satellite information communication, radar, radio astronomical telescopes, etc., all show its great powers. Strong magnetic radiation will form the thinking extension of the human brain, leading to the brain's delusional associative judgment. Electromagnetic and natural environmental influences can cause the human body to act in harmful ways to society. In addition, the horror caused by high-rise buildings to human beings, the serious pollution of the environment and many social disadvantages will have huge psychological pressure on human thoughts.

3. Cosmic magnetic field

(1) The solar magnetic field

The general magnetic field of the sun refers to the weak magnetic field in the quiet area of the sun, the strength is about 1x10-4~3x10-4 Tesla, it is polar opposite in the north and south polar regions of the sun, and the observation in recent years has found that most of the magnetic flux tubes through the photosphere are concentrated on the surface of the sun called the magnetometer area, its radius is 100~300 kilometers, the field strength is 0.1~0.2 Tesla, and most of the magnets appear in the boundary and activity area of rice grains and super rice grains. If you think of the Sun as a star, you can measure its overall magnetic field of about 3x10-5 Tesla, which is reversed from east to west.

(2) Magnetar

Stars with strong magnetic fields. Usually the spectral type is a, and the magnetic field can be as strong as 3 ters (Slav). The magnetic field strength of magnetars is still changing, so they are also called magnetos. Most magnetovariables are A-type special stars. In some magnetovariables, not only the magnetic field changes periodically, but also the luminosity and spectroscopy. The photochange period is 1~25 days, and the amplitude change is generally not more than 0.1.

"Magnetar" (magar) is a type of neutron star, they all have an extremely strong magnetic field, through the decay generated by it, so that it can continuously release high-energy electromagnetic radiation, mainly X-rays and gamma rays. The theory of magnetars was developed in 1992 by scientist Robert Brown. Robert Duncan and Christopher. Christopher Thompson first proposed that in the years that followed, this hypothesis was widely accepted to explain observable objects such as soft gammarepeaters and anomalousx-raypulsar.
