Why don't ferrite magnets rust?
The chemical name of ferrite magnet is iron tetroxide. The main components are: Fe3O4. It is already an oxide of iron, so it is very difficult to be oxidized again. Other magnets (the main component is iron) are made of magnetized metal iron or other elements. Like other iron and steel, they can be oxidized and rusted, and the oxidized part will lose their magnetism.
What are the advantages (advantages) of ferrite magnets
1. Low cost, low price. Raw material cost is cheap.
2. Good temperature stability. It can be used in temperatures of -40 degrees Celsius and +350 degrees Celsius.
3. It is just mentioned that it does not rust.
4. The demagnetization curve is approximately a straight line.
5. Light weight, density is (4.6-5.1) X103kg/M3
6. The anisotropy constant of the magnetic crystal is large.
7. Large coercivity Hc (between AlNiCo alloy material and rare earth cobalt permanent magnet material)
8. High resistivity.
The human body lacks water, the big office drinks water to help longevity
Chinese medicine interprets the consequences of human water shortage. The office drinks longevity. The traditional Chinese medicine is called the body fluid. Under normal circumstances, adults need 2000--3000 ml of water per day. The stronger the physical activity and the more sweating, the need for water. The greater the amount. Drinking water is not timely, and the lack of water in the body will bring many problems. In general, adults every day
