1. Neodymium magnets waxay inta badan ka kooban yihiin neodymium, iron iyo boron.Birta magnetka ku jirta ayaa daxalaysa haddii ay hawada gasho.
2. Taasi waa sababta dhammaan magnets neodymium ee xooggan ee warshadeena ay ku daboolan yihiin dahaarka difaaca, dahaarka ilaalintu waa mid aad u dhuuban (heerka micron) oo aan wax saameyn ah ku yeelanin adhesion magnet neodinio.
3. Neodymium magnets ayaa lagu heli karaa dahaar badan oo kala duwan iyo xulashooyin dhejis ah.Dahaarka ugu caansan ee magnet-ka neodymium waa nikkel plating.Inkasta oo inta badan loogu yeero si fudud sida "nikkel plating," doorashadan nikkel dhab ahaantii waa dahaadh saddex-lakab ah oo ka kooban lakabka nikkel, lakabka naxaasta, iyo daahan nikkel ah.
4. Nikkel caadi ahaan loo isticmaalo (NI-CU-NI), zinc, copper, epoxy resin, dahab, qalin, passivation, daahan PVC, iwm.
