When your project requires a large number of permanent magnets, it is a good choice to choose to cooperate with a Chinese manufacturer. There are thousands of permanent magnet factories in China, they can provide you with high quality and low price permanent magnet products.
A permanent magnet is a magnet that does not lose its magnetic field. Permanent magnets are made of special alloys (ferromagnetic materials) such as iron, nickel, and cobalt, as well as alloys of several rare earth metals and minerals, such as magnets. Unlike electromagnets, permanent magnets produce a permanent magnetic field without any external magnetic or electrical power source. This permanent magnetic field is continuously generated by the structure of the magnet, which has inherently positive and negative ends.
There are 5 common types of permanent magnets, so which one is the best? The answer is not always straightforward, as it depends on the purpose of the permanent magnet. The five permanent magnets are Alnico, Samarium Cobalt, Ferrite, Flexible Rubber and the strongest permanent magnet, Neodymium magnet.
