I grabbed them with my hands, and they were sucked tightly into a big piece, which was very tough! The child said: it can be decompressed. It's really cool to pinch so hard and decompress! Bucky balls are as magnetic as 4000 gauss, so children should be careful when playing. This dangerous place is first of all worried about being eaten by mistake. In addition, people with intensive phobia should feel uncomfortable at first sight.
Of course, some parents will immediately think of the harm of too strong magnetic force to their health. Our Ming Jian device is also a magnetic therapy instrument, and some parents will ask similar questions. The magnetic field brought by the built-in device is not as strong as that of the bucky ball. The so-called magnetic force is not only determined by the magnetic field strength alone, but also related to the constituent materials. Parents think of strong magnetism and can promote it. Usually we use "gauss" as the unit of magnetic field, and 10000 gauss is 1 Tesla. Gauss and Tesla are also easy to remember. One is a mathematician, and the other is the father of alternating current. The name Tesla is now used in modern electric vehicles because the founder admired him very much since he was a child. So you just need to remember that Tesla is awesome, and you don't have to worry too much if you don't reach the level of Tesla. However, radiation from synthetic materials does cause harm. Therefore, we should carefully use the source of magnetic products and understand the synthetic components.
The principle of using magnetic bars to care for eyes has been in existence since ancient times. Sun Simiao first used magnetic sand and bian stone (also a natural magnet) to treat and care for eyes. Sun Simiao is a very incredible person. I've been wondering how he learned that the eyeball is a magnetic field. Many years later, it was found that when the visual cells on the retina convert light into information, they radiate current. Although tiny, electromagnetic * * * exists, and the human eye itself is a complete small magnetic field. In the human body, eyeball, brain and heart are three places with relatively large magnetic fields. This is different from the energy magnetic field in chicken soup and metaphysics.
There is no doubt that the human eye has a magnetic field. If a person turns his back and someone is staring at him behind him, sensitive people will feel it. In another case, in the Korean drama "You from the Stars", the hostess said that two people would fall in love with her for a few seconds. I wonder if this is also the principle of magnetic field?
