Permanent Magnetic Assembly Manufacturer China Rare Earth Magnet Limited
Generally, as we all know, the opposite poles of permanent magnets attract together and the same repel. Thus, in order to connect the same poles together to achieve a concealed S or N pole like the drawing below, what we need is Sandwich Magnet, it is a ferrite magnetic assembly.
Namely, it is to put a non-magnetic material, usually steel, between two magnets, or put a magnet between two steels just like a sandwich. In this way, the steel material can channel the magnetic force into a particular direction to achieve the maximum strength. According to the test with a flat steel plate, surprisingly, the force of sandwich magnet is almost 32 times stronger than the common single one.
The permanent magnet materials are always ferrite magnets, but sometimes neodymium magnet, SmCo or Alnico is also workable according to the special requirements of customers. And the form of steel includes plates, cups, blocks and so on, which mainly depends on its usage. Besides, the customers can choose whether to fix the steel permanently on the magnets by glue or just make them hold on together. In addition, if you want to hang on something or add a hook, it would be better to drill a through hole or a countersunk hole on the sandwich magnet.
In a word, the sandwich magnets are the best option for several applications for its high strength and low cost, such as door latches, money clips and so on.
