Xalka demagnetization heerkulka sare ee NdFeb

Saaxiibada qaar aqoon u leh magnet-ka way garanayaan taasNdFeb Neodymium Magnetwaxaa guud ahaan loo aqoonsan yahay inay yihiin wax qabad sare iyo wax soo saarka magnet-ka ee wax-ku-oolka ah ee warshadaha walxaha magnetic hadda.Goobo badan oo tignoolajiyada sare ah ayaa u qoondeeyay inay sameeyaan qaybo kala duwan, sida militariga difaaca qaranka, tignoolajiyada elektiroonigga ah, qalabka caafimaadka, qalabka korantada iyo meelo kale ayaa ku lug leh. deegaanka heerkulka sare ayaa soo jiitay dareen badan. 

Waa maxay sababtaMagnets Joogtada ah ee NdFebhoos u dhacay heerkulka sare?

NdFeb degaussing heerkulka sare waxaa lagu go'aamiyaa qaab-dhismeedka jireed. The magnetic field waxaa dhalin kara by magnetka, sababtoo ah electrons ay sidday maaddadu waxay wareegaan agagaarka atamka jihada gaar ah, taas oo dhalinaysa xoog birlab gaar ah, ka dibna waxay leedahay saamayn. Ku saabsan arrimaha la xidhiidha agagaarka. Laakiin electrons agagaarka atamka si waafaqsan jihada la aasaasay ayaa sidoo kale waxay leedahay xaaladaha heerkulka gaar ah, wax magnetic kala duwan u adkeysan karaan heerkulka waa ka duwan yahay, haddii ay dhacdo heerkul aad u sarreeya, elektarooniga ah ayaa ka leexan doona track asalka ah, ifafaale fowdo ah, walxaha magnetic waqtigan goobta magnetic maxalliga ah ayaa xanaaqi doona, iyo demagnetization.

Si kastaba ha ahaatee, iska caabinta heerkulka ee magnets NdFeb waxay u badan tahay inay ku wareegsan tahay baidu, taas oo ah, in ka badan baidu waxay u muuqan doontaa ifafaale demagnetization, haddii heerkulku sarreeyo, ifafaale demagnetization waa mid aad u daran.

Dhowr xal oo wax ku ool ah oo demagnetization heerkulka sare ee NdFeb, magnets ayaa la soo bandhigay.

Marka hore, ha dhigin sheyga magnetka ee NdFeb heerkul aad u sarreeya, gaar ahaan fiiro gaar ah u yeelo heerkulkiisa muhiimka ah, oo ah baidu, waqti ku hagaaji heerkulka deegaanka shaqada, si loo yareeyo dhacdooyinka demagnetization.

Midda labaad waa in la hagaajiyo waxqabadka alaabada iyadoo la adeegsanayo magnets NdFeb laga soo bilaabo dhinaca farsamada, si ay u yeeshaan qaab-dhismeed heerkul badan oo aan si sahlan u saameynin deegaanka. 

Seddexaad, waxaad dooran kartaa maaddooyinka xoogga badan ee qasabka ah oo leh isku ururin tamar magnetic.Haddaysan ahayn, waa inaad wax yar u hurtaa ururinta tamarta magnetic, oo aad hesho agab leh ururinta tamarta magnetic hoose iyo xoog xoog badan oo xoog leh, laakiin mar dambe ma jirto, waxaad dooran kartaa cobalt samarium;demagnetization dib loo celin karo, kaliyasamarium cobaltwaa la heli karaa.
