Igwe ndọta dị nro1J85/ FeNi 85 / Ni80Mo5
A na-ejikarị eme ihe na mpaghara abụọ maka ntụgharị ike na nhazi ozi
Na ike ụlọ ọrụ, tumadi na elu magnetik nwere elu magnetik induction na ala isi ọnwụ nke alloy. Na ngwá electronic, tumadi na ala ma ọ bụ ọkara alloy nwere nnukwu magnetik permeability na ala mmanye ike. N'ebe dị elu, a ga-eme ya na mpempe dị mkpa ma ọ bụ alloy elu resistivity. Na-ejikarị mpempe akwụkwọ ma ọ bụ warara.
Ihe ndọta dị nro na-agbanwe maka ojiji, n'ihi na a na-eme ka ikuku magnetik na-agbanwe agbanwe n'ime ihe ahụ, na-akpata ọnwụ, obere nkwụsị nke alloy, nke ka ukwuu na ọkpụrụkpụ, na-abawanye ugboro nke oghere magnetik ọzọ, eddy ugbu a na-efunahụ ukwuu, magnetik na-ebelata ihe ndị ọzọ. Maka nke a, a ga-eme ka ihe ahụ dị ntakịrị (teepu), na elu ya na mkpuchi mkpuchi, ma ọ bụ iji usoro ụfọdụ na-eme ka ọkpụkpụ na-emepụta ihe mkpuchi oxide, ihe alloys ndị a na-ejikarị magnesium oxide electrophoresis mkpuchi.
Ígwè-nickel alloy na-abụkarị n'ụzọ ndọta ọzọ, tumadi maka ígwè yoke, ọsọ agba anọ, obere ihe ngbanwe ike na ihe mkpuchi magnetik.
