This is the NEODYMIUM SPHERE MAGNETS Rare Earth, also it is the neodymium magnet, the neodymium magnet is the third generation rare earth permanent magnet.
The Physical Properties of Neodymium Permanent Magnete Super Strong Magneti Neodimio Rare Earth Aimant Neodyme:
It have two mainly classification, the sintered neodymium magnet and bonded neodymium magnet.
The picture's product is the sintered neodymium magnet.
1. Magnets grade: from N35 To N50, from N Series to AH Series.
2. Magnets size: 3mm to 50mm for diameter can be available.
3. Magnetism direction: Always magnetized via diameter direction.
4. Magnets coating: Nickel, Zinc, Black Epoxy, Ag, Au Etc.
also,we can drill hole on the ball....
