Toshe Zoben Round Arc Magnet na Dindindin na Ferrite
Bayanin Samfura
Ferrite Magnet (wanda kuma aka sani da yumbu magnet) maganadisu ce ta dindindin.
An samo su galibi tushen Strontium (SrFe2O3), wanda aka ƙera shi tare da ƙari na Strontium Carbonate don haɓaka wasan kwaikwayo daga tushen Barium da ba a gama ba (BaFe2O3).
Kyakkyawan ƙarfin tilasta su ya fito ne daga babban anisotropy crystal na strontium iron oxide. Koyaya, ana iya samar da sassan isotropic inda ake buƙatar magnetization mai sauƙi da sauƙi.
Dangane da halayen lantarki, tsayayyar ferrite ya fi girma fiye da na ƙarfe da kayan maganadisu na alloy, kuma yana da kaddarorin dielectric mafi girma.
Kaddarorin maganadisu na ferrite suma suna nuna iyawa mai girma a mitoci masu yawa.
Ferrite ba ya aiki kuma yana da babban juriya ga lalata, acid, gishiri, da mai. Siffofin da aka fi sani suna da sauƙi, kamar diski, tubalan, silinda, zobba, da baka.
Ana amfani da maganadisu na Ferrite a aikace daban-daban a cikin shekaru da dama da suka gabata, kamar lasifika, injina, da janareta.
