I-Demagnetization Curves

Ijika le-Demagnetization, noma i-BH curve iyiquadrant yesibili ye-hysteresis yezinto eziqinile zikazibuthe ezihlanganisa nezibuthe zomhlaba eziyivelakancane.Inikeza ulwazi mayelana nezici kazibuthe zikazibuthe, okuhlanganisa amandla kazibuthe kanye nokumelana ne-demagnetize.Ikakhulukazi ijika ekushiseni okuphezulu linikeza ireferensi ebalulekile konjiniyela ukubala futhi bathole izinto ezifanelekile zikazibuthe kanye nebanga ukuze bahlangabezane nemfuneko yabo yokusebenza.Ngakho-ke silungiselela amajika okukhipha kazibuthe emazingeni okushisa ambalwa aphezulu okushisa ozibuthe be-Sintered Neodymium kanye nozibuthe be-Samarium Cobalt ngaphambi kwebanga ngalinye elitholakalayo.Sicela uchofoze iseli ngalinye ukuze uthole amajika alo demagnetization ngokulandelana.
