Zoo Siab
Covmagnetization los yogsib nqus sib cais Nws yog txheej txheem uas ua kom zoo dua ntawm cov yam ntxwv sib nqus ntawm qee yam tshuaj txhawm rau cais cov khib nyiab sib txawv.
Hlau nplaum yog qhov tshwm sim ntawm lub cev uas cov khoom ua kom muaj zog txaus lossis quab yuam quab yuam. Txhua yam ntaub ntawv raug cuam tshuam los ntawm cov hlau nplaum, txawm li cas los xij, qee qhov cuam tshuam rau ntau dua li lwm qhov.
Cov khoom siv nrog cov khoom siv hlau yog nyiam rau cov hlau nplaum. Yog li ntawd, thaum qee qhov me me ntawm cov hlau tau tawg ntawm lwm cov khoom, lawv tuaj yeem sib cais ua tsaug rau cov hlau nplaum.
Txhua qhov chaw sib nqus muaj qhov tshwj xeeb siv. Kev siv zog yog muab los ntawm tus naj npawb ntawm cov kab ntws uas dhau los ntawm ib cheeb tsam. Txhua lub hlau nplaum muaj lub zog sib nqus sib nqus ze rau nws saum npoo peb. Gradient teb yog qhov nrawm uas qhov kev siv zog nce mus rau qhov sib nqus.
Lub zog ntawm cov hlau nplaum yog nws lub peev xwm los nyiam cov ntxhia. Nws nyob ntawm nws lub zog hauv cheeb tsam thiab nws cov gradient teb.

Cov ntxhia tau muab cais raws li lawv cov kev sib nqus sib nqus hauv:
- Paramagnetic.Lawv dhau los ua cov hlau nplaum los ntawm kev siv daim teb sib nqus. Yog tias tsis muaj thaj chaw, tom qab ntawd tsis muaj kev sib nqus. Ntawd yog, cov ntaub ntawv paramagnetic yog cov ntaub ntawv nyiam rau cov hlau nplaum, tab sis lawv tsis dhau los ua cov khoom siv hlau nplaum tas mus li. Lawv tau muab rho tawm nrog kev siv sib nqus sib nqus siab.
- Ferromagnetic.Lawv tau ntsib kev sib nqus siab thaum siv daim teb sib nqus thiab tseem muaj cov hlau nplaum txawm tias thaum tsis muaj chaw sib nqus. Lawv tau muab rho tawm nrog kev siv qis sib nqus sib nqus.
- Diamagnetic.Lawv tawm tsam qhov chaw sib nqus. Lawv tsis tuaj yeem rub tawm cov hlau nplaum.
Piv txwv ntawm magnetization
- Recycling ntawm tsheb. Tsheb tau ua los ntawm cov khoom sib txawv. Thaum lawv raug pov tseg, lawv raug tsoo thiab tom qab ntawd, ua tsaug rau cov hlau nplaum muaj zog, tsuas yog cov khoom siv hlau uas tau muab rho tawm, uas tuaj yeem rov ua dua tshiab.
- Hlau thiab leej faj. Hlau tuaj yeem muab rho tawm los ntawm kev sib xyaw nrog leej faj ua tsaug rau cov hlau nplaum.
- Cov menyuam siv. Cov hlau nplaum sib nqus tau siv los cais cov khoom siv hlau (hlau muaj) hauv cov khoom ntws ntawm cov menyuam thauj khoom lossis cov khoom hla.
- Sib nqus sib nqus. Kev teeb tsa cov hlau nplaum sib nqus hauv cov kav dej thiab cov channel tso cai rau tshem tawm tag nrho cov xim hlau uas ntws hauv dej.
- Mining. Magnetization tso cai rau hlau thiab lwm yam hlau sib cais los ntawm cov pa roj carbon.
- Xuab zeb. Tshem tawm cov ntaub ntawv hlau tawg thoob plaws hauv cov xuab zeb.
- Dej ntxuav. Magnetization tso cai tshem tawm cov ntxhia ntxhia los ntawm cov dej ntws, zam kev kis kab mob.
