Magnet mgbanaka Neodymium omenala maka moto na ọkà okwu
Nkọwa ngwaahịa
Neodymium bụ metal ductile na ọlaọcha na-acha ọcha. Neodymium bụ paramagnetic siri ike. Ngwa bụ isi nke neodymium dị na magnetik na-adịgide adịgide dị elu dabere na Nd2Fe14B nke a na-eji na igwe eletrik na igwe ọkụ na-arụ ọrụ dị elu, yana na magnetik spindle maka draịvụ ike kọmputa na ikuku ikuku. Neodymium magnetik dị n'ụdị dịgasị iche iche nke ụdị, nha na akara ule. Ihe ndọta mgbanaka dị ka diski ma ọ bụ cylinders, mana nwere oghere etiti.
Mgbanaka NdFeB Njirimara Igwe Ọdụdọ
1. Igwe ọkụ na-arụ ọrụ dị elu
Ihe ndọta mgbanaka neodymium N48H nwere ezigbo nguzogide okpomọkụ. Maka usoro NH nke ndọta NdFeB, okpomọkụ kachasị arụ ọrụ nwere ike iru 120 ℃.
