How are electromagnetic waves formed? Will it cause harm to the human body?

Electromagnetic waves are formed by the conversion of electricity and magnetism in the electromagnetic field, and if they accumulate to a certain amount, they will cause harm to the human body. Of course, the harm to the human body is also the result of experimental research, and there are not a large number of people to do scientific experiments, so we don't have to worry too much, just pay more attention to life. <>

How is electromagnetic wave formed, electromagnetic wave is a form of movement of electromagnetic field, the changing electric field will produce a magnetic field, that is, the current can produce a magnetic field, and the changing magnetic field will produce an electric field. The changing electric field and the changing magnetic field constitute a unified field, which is the electromagnetic field, and the propagation of the electromagnetic field in space forms electromagnetic waves, also commonly known as "radio waves", which are generally invisible and intangible. When the frequency of electromagnetic waves is very small, they cannot propagate freely in space, so they need to propagate with the help of intermediate materials, and when the frequency reaches a certain value, they can propagate freely in space.

In fact, there are a lot of electromagnetic waves in life, the infrared and visible light emitted by the sun is the strongest electromagnetic radiation in nature, when it irradiates the human body, it will produce a thermal effect, making people feel hot, hot and painful, which is caused by electromagnetic radiation. Generally speaking, if you can't go to the sun, there is no big problem, but if you sun is too long or the sun is too strong, it will cause damage and cause certain harm to people. <>

The second is that the electronic products in our lives, such as induction cookers, microwave ovens, mobile phones, computers and other electronic devices, can produce electromagnetic waves of a certain intensity, generally speaking, the electromagnetic wave radiation generated by these electronic devices is not very strong, and will not cause much harm to our human body. However, studies have shown that if electromagnetic waves accumulate in the human body to a certain amount, it will bring many diseases to the human body, so we should pay more attention in our lives and try to stay away as much as possible.

The generation of electromagnetic waves, the family of electromagnetic waves, the discovery of electromagnetic waves, the strength of electromagnetic waves.

Electromagnetic waves are generated because a magnetic field is generated around the changing electric field, and the changing electromagnetic field forms electromagnetic waves in the process of propagation. It is very harmful to the human body.

Electromagnetic waves are a type of energy. There will be electromagnetic waves in ordinary environments, which will be basically harmless to the human body, but will cause irreversible damage to the human body under high-frequency electromagnetic waves.

The principle of electromagnetic wave generation is that the changing electric field will produce a magnetic field (that is, the current will produce a magnetic field) As long as it is charged, there is a magnetic field, which will cause more or less harm to the human body, so it is best not to discharge electrical discharges in the bedroom, and it is best to turn off the mobile phone when sleeping, and the computer radiation is greater, and people who often work in front of the computer should drink more green tea to reduce radiation damage.
