Injection molding magnetic ring wholesale for magnets we are not unfamiliar, childhood played rectangular a small black magnet, only understand that magnets can attract each other will be independent of each other, but do not know the working principle of the magnet and its magnets also have other types, and even always think that magnets only one kind of appearance and a tone. So what is the magnet, what is the plastic magnetic ring wholesale, this article we come to understand.

Magnets are natural substances and can be made by human hands. A magnet is an object that can form an electromagnetic field. It can absorb all metals containing ferromagnetic materials, such as nickel, cobalt, steel and other metals. Diamagnetic chemicals such as copper or aluminum cannot be magnetized with the magnetic field of the magnet. The magnet has S and N2 degrees generally called S is the magnet of Antarctica, the N pole is the magnet of the North Pole, and the relativity of the Earth is that the North Pole of the earth magnetic field is S pole, Antarctica is N pole. Opposite-sex magnets attract opposite-sex friends, and homosexuals repel each other.

The wholesale cost of ferrite plastic magnetic is generally iron, cobalt, nickel and other molecules, and other types of natural magnets will continue to have other costs. For example, Ndfeb magnet magnet is made of neodymium, iron, boron produced by the square crystal structure crystal, is the strongest magnetic magnet at this stage, also known as super strong magnet, there are sintered and bonded NdFEB magnet these two. Ferrite is a metal metal oxide, ferrite resistance than metal, aluminum alloy permanent magnet material. Samarium cobalt is made of samarium, cobalt and other metallic Greek soil raw materials by smelting into aluminum alloy sintering. Aluminum nickel cobalt is based on the production process is not the same to be divided into sintering and forging. At this stage, the most commonly used in the market is ascribed to Ndfeb magnet and ferrite. When I was a child, I saw that kind of ferrite.
