Sababtoo ah dhererka, iyada oo aan lagu dhejin kiis aan magnet ahayn, magnetized axial magnetized magnetized waa u fududahay dadka inay ku qabtaan faraha ka dibna si ballaaran ayaa loo iibsadaa oo loo isticmaalo codsiga soo jiidashada guud ee dadka caadiga ah ee nolol maalmeedka. Waxa kale oo loo yaqaan sida dhululubo magnet dhul dhif ah, dhululubo Neodymium magnet, NdFeB dhululubo magnet, iwm.
Caadiyan Neodymium cylinder magnetized magnetized dhex dhumucdiisuna waxay si toos ah u soo saaray iyada oo la cadaadinaya block adag oo ah dhululubo semi-dhammeeyay. Waa sahlan tahay oo raqiis ah in lagu sameeyo bir bir ah oo qallafsan ilaa cabbirka magnet-ka la dhammeeyey. Marka hore, shiidida xudunta la'aanta ayaa loo isticmaalaa in lagu shiido dhexroorka saxda ah. Marka labaad dhumucda ama dhererka diyaaradda waxaa lagu shiidi doonaa magnet dhululubo ah oo dhammaatay, ama la jarjaray dhowr qaybood oo birlab ah oo dhererkoodu ka gaaban yahay. Haddii dhererka magnet-ka ugu dambeeya ee Neodymium cylinder uu aad u dheer yahay, tusaale ahaan 60 mm ama sifooyinka magnetic loo baahan yahay waa sarreeyaa, riixitaanka magnetka dhululubada si toos ah way adag tahay in la gaaro xoogga birlabeedka sare. Kadibna waxaa laga yaabaa in la soo saaro oo laga farsameeyo blocks magnet leydi ah.
Yurub iyo Mareykanka shirkado badan ayaa bixiya wax iibsiga online ee cabbirada caadiga ah ee Neodymium magnets leh darajooyin sare, sida N40, N42, N45, N52, iwm
