First, the history of magnetized water
Magnetic force is one of the four basic forces in nature. The compass of one of the four great inventions in ancient China is an example of the clever application of magnetic force. Li Shizhen, a medical scientist of the Ming Dynasty, discovered that the magnetically treated water had the effect of “removing sputum, long skin”, “long drinking, having children, suitable for wine” and “aphrodisiac”. Fitness, treatment of a variety of diseases. However, the magnetic material used by the ancients is a naturally occurring natural magnet, magnetite, whose magnetic properties are very low compared with modern synthetic magnetic materials.
Second, the high-strength magnetic king - NdFeB
In 1983, the third generation of NdFeB was introduced. Its magnetic field strength is more than ten times that of ordinary magnets. Its service life is more than ten years. It is the highest energy product (MGOE) discovered by human society. Magnetic material, known as the "permanent magnet king." Widely used in high-tech fields such as national defense, aerospace technology, microwave, communications, electronics, and healthcare.
