Qallooca Demagnetization, ama qalooca BH waa rubuc labaad ee hysteresis ee qalabka birlab adag oo ay ku jiraan magnets dhulka naadir ah. Waxay bixisaa macluumaad ku saabsan sifooyinka birneedka ee magnetka, oo ay ku jiraan xoogga goobta magnetic iyo iska caabinta demagnetize. Gaar ahaan qalooca heerkulka sare wuxuu siinayaa tixraac muhiim ah injineerada si ay u xisaabiyaan oo ay u ogaadaan walxaha magnet ku habboon iyo darajada si ay u buuxiyaan shuruudahooda shaqo. Sidaa darteed waxaanu halkan kuugu diyaarinaynaa qaloocyada demagnetization ee dhowr heerkul shaqo oo sarreeya oo loogu talagalay magnets Neodymium iyo Samarium Cobalt magnets oo hore u sii qaadaya darajo kasta oo la heli karo. Fadlan ku dhufo unug kasta qaloocyada demagnetization siday u kala horreeyaan.
