Key Advantages of permnent ring magnets:

1) The Neodymium Ring Magnet are the most powerful commercially produced magnets.
2) The Ndfeb Ring Magnets have a higher Maximum Energy Product, (BH). Max, which can easily reach 30 MGOe and even goes up to 50 MGOe.
3) The Neodymium Magnets can replace SmCo magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade.
4) The Neodymium Magnets has very high strength.
5) Relatively low cost.
6) Compared to AlNiCo and SmCo magnets, relatively easy to machine
