Courage magnet manufacturers in China not only provide magnet sales, but also provide magnet FAQs. Today, they answer the questions of netizens: Why is the magnetism of magnets not as strong as before?
The reason why NdFeB magnets are magnetic is that the regular arrangement of iron atoms in the magnet enhances the magnetic properties. Let's think about it in reverse. If the arrangement of iron atoms in the magnet is disrupted, will the magnetic properties weaken or even not exist? We can also do an experiment, put a piece of magnetic steel through fire and then cool it down, we will find that the magnet no longer has obvious magnetic properties, the reason is that after the magnet is heated, the arrangement of its iron atoms is not regular, the arrangement is disordered, so the magnet loses its magnetism.
Another reason is that it is not the same as the previous materials. For example, it was n52 before, and now it is N48.
The above is the relevant introduction about the weakening of magnet magnetism. Our company mainly specializes in rare earth neodymium magnets, ceramic ferrite magnets, motor arc magnets, and multi-pole ring magnets. Customers in need can contact us to quote for you.
