Whether magnets have a big impact on the body or not

First of all, say hello to the landlord! The eyes are very painful and you can't open your eyes, it's best to go to the hospital first to check what the cause is, it shouldn't be complicated.

As for the magnet you are talking about, it is a magnetic field in a broad sense

Scientists explain that when a magnetic field acts on the human body, the degree to which the various systems of the human body participate in the response can be arranged in the following order: nerves, endocrine, sensory organs, cardiovascular, blood, digestion, muscles, excretion, respiration, **, bone. From this point of view, the nervous system and endocrine system are the most sensitive to magnetic fields.

At the same time, in the nervous system that is most sensitive to the action of magnetic fields, especially the hypothalamus and cerebral cortex.

People may be tempted to ask, what kind of harm will a weak magnetic field have on people? The researchers explained that the brains of laboratory rats can be so significantly damaged in a weak magnetic field environment that it is certainly impossible for humans to completely avoid such adverse effects. People are often exposed to some weak magnetic fields in their daily lives, and these weak magnetic fields are usually active around the human brain, such as the hair dryer we use to blow hair, the electric blanket and razor we sleep on.

Although it only takes us a few minutes a day to use these appliances, we shouldn't take the harm they can cause lightly.

The scientists also said that although they have not yet studied whether this kind of damage to the brain from weak magnetic fields will accumulate over time, the possibility of such a cumulative effect cannot be completely ruled out based on the results of the research so far.

In addition, our earth is a big magnetic field! Hehe.

There is a weak magnetic field around the human body that adapts to the geomagnetic field, and if it is strongly disturbed by other magnetic fields, it will have a certain effect, especially if the transformer produces that kind of change, after all, the magnetism generates electricity, and nerve conduction depends on the current.

The magnetic induction strength of ordinary magnets is not high enough to cause harm to people. If it is applied to a certain part for a long time, it is still being studied, but it still has some impact on people who have a pacemaker, so special attention should be paid.

The magnet will also interfere with the CRT, because the CRT is scanned to produce an image by the flow of electrons under the deflection of the magnetic field, and the external magnetic field will distort the magnetic field in the picture tube, so that the electron flow will deviate from the normal scanning trajectory, resulting in image distortion black and white and color display and color spots. Generally, many ** speakers use magnetic shielding technology, which will not cause any impact when placed next to CRT.

A sweep of the horn magnet over the CRT will see a noticeable effect. There is no lifetime hazard to CRT, at most it is a single point of burn caused by long-term image distortion.

I think it will.

The magnetic waves emitted by the magnet and the magnetic waves emitted by the earth will cancel each other out. It is not good for the human body.

If you put it together with your phone, it will be scrapped for a long time.

No, but it certainly has an impact.

The role of the magnet:

1. Physical action.

1), Guide North.

2) Attract small and light objects.

3) The electromagnet can be used as an electromagnetic relay.

4) Electric motor.

5) Generator.

6) Electroacoustics.

7) Magnetic therapy.

8) Magnetic levitation.

9) Nuclear magnetic resonance.

2. Therapeutic effect.

1) The magnet is salty and flat; return to the liver and kidney meridians; quality is heavy and subdued;

2) It has the effect of calming the liver and latent yang, brightening the ears and eyes, calming the nerves, and calming the breath;

3) It is mainly used for the treatment of liver yang dizziness, palpitations, insomnia, dizziness, tinnitus, deafness, kidney deficiency and asthma.

Magnets do not have adverse effects on the body, so you can use magnetic materials with confidence. The earth itself has a very strong magnetic field, so human beings themselves have a kind of adaptation and even dependence on magnetism. A weakly stable magnetic field is good for the body, and magnetotherapy is often used in medical treatment.

Electromagnetic waves, on the other hand, are high-energy waves whose frequency can have adverse effects on the body. Therefore, magnets are not harmful to the human body.

The composition of the magnet is iron, cobalt, nickel and other atoms, and the internal structure of the atoms is relatively special, and it itself has a magnetic moment. Magnets are capable of generating magnetic fields and have the property of attracting ferromagnetic materials such as iron, nickel, cobalt, and other metals.

Magnet type: shape magnet: square magnet, tile magnet, special-shaped magnet, cylindrical magnet, ring magnet, disc magnet, magnetic rod magnet, magnetic stand magnet, attribute magnet:

Samarium cobalt magnets, NdFeB magnets (strong magnets), ferrite magnets, Alnico magnets, iron-chromium-cobalt magnets, industry magnets: magnetic components, motor magnets, rubber magnets, plastic magnets, etc. Magnets are divided into permanent magnets and soft magnets, permanent magnets are added with strong magnetism, so that the spin of magnetic substances and the angular momentum of electrons are arranged in a fixed direction, and soft magnets are with electricity.

It is also a method of adding magnetic force) Waiting for the electric current to remove the soft iron will slowly lose its magnetism.

The midpoint of the bar magnet is hung with a thin wire, and when it is stationary, its two ends point to the south and north of the earth, the one end pointing north is called the north pole or n pole, and the one end pointing south is the guide pole or s pole.

If you think of the Earth as a large magnet, the Earth's magnetic north pole is the guide pole, and the geomagnetic south pole is the north pole. Between magnets and magnets, the poles of the same name repel each other, and the poles of the same name attract each other. So, the compass repels the South Pole, the north arrow repels the North Pole, and the compass attracts the north pole.

Classification: Magnets can be divided into "permanent magnets" and "non-permanent magnets". Permanent magnets can be natural products, also known as natural magnets, or they can be artificially manufactured. Non-permanent magnets, such as electromagnets, only appear magnetic under certain conditions.
