Large ferrite ring, that is, large diameter size ring ceramic ferrite magnet, is much cheaper than rare earth neodymium magnet in price, so it can replace NdFeb in some applications. Today, this article mainly introduces the application and size of large ring ferrite.
Where are large ring ferrites mainly used?
Mostly used for magnetic suspension, speakers (horn), industrial machinery and equipment.
What are the common specifications and sizes of large ring ferrites?
Different customers have different understandings of large. Some customers need 100mm large, some customers need 150mm large, and some customers need a large magnetic ring with an outer diameter of 200mm. The following are some specifications of large ferrite magnetic rings listed by Xiaobian.
