The magnetism of the round magnetic chunk is composed of strong magnetic materials, mainly including hard alloy, aluminum nickel silicon vanadium alloy, ferromagnet, etc. The magnetic strength is customized by the customer. In general, the magnetic strength is around 50-100 microtesla, depending on the customer's own needs and application environment.
The operating temperature of round magnetic chunks is generally between - 30°C + 80°C, which can meet the requirements of most application environments.
The shape of the magnet：
1. Ring magnet, the shape of the magnet is a ring.
2. Button magnet, the magnet is like a button.
3. Hoof-shaped magnet, the magnet is in the shape of a horseshoe.
4. Bar magnet, the magnet grows into a bar.
5. Square magnet, the magnet is square or rectangular.
6. Round magnet, the magnet is round.
7. Magnet is not invented by man, it is natural magnetite. The ancient Greeks and Chinese discovered a kind of naturally magnetized stone in nature, which they called "magnets". This kind of stone can magically attract small pieces of iron, and always point in the same direction after swinging at will. Early navigators used this magnet as their earliest compass to identify directions at sea. It should be the Chinese who first discovered and used magnets, that is, using magnets to make "compass", which is one of the four great inventions of China.
This Round Magnetic Chunk not only has the characteristic of strong adsorption, but also is very easy to use. You can simply attach it to a desktop, wall, or other object without the need for additional nails, glue, or any other auxiliary materials. From now on, these small magnetic blocks can easily help you manage your books, files, or other items, making your life cleaner and more organized.
