I often deal with magnets, are magnets harmful to the human body?

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.
