Features
1. Ndfeb ring or coil magnet has superior magnetic properties than other magnets
2. Higher unit magnetic properties
3. Smaller size and lighter weight in designing devices
4. Mostly an iron based alloy, NdFeB type rare earth magnet is much more prone to surface oxidation or rust, and elimination. Users should consider magnet coating, plating or suitable surface treatment
5. Less prone to chipping during handling
6. Lower temperature coefficient of magnetic properties than ceramic, higher tha
