Rau piav lub phenomenon ntawm ferromagnetism , Weiss tau npaj ib lub tswv yim hypothetical ntawm ferromagnetic domains . Nws postulated tias cov atoms nyob sib ze ntawm lub ferromagnetic cov ntaub ntawv, vim muaj qee qhov kev sib pauv kev sib tshuam, los ntawm ntau qhov chaw me me, hu ua thaj chaw.

Hais txog qhov no, koj txhais li cas los ntawm magnetic domain?

A sib nqus domain yog ib cheeb tsam hauv ib Sib nqus cov khoom nyob rau hauv uas lub magnetization yog nyob rau hauv ib tug uniform kev coj. Qhov no txhais tau tias tias tus kheej Sib nqus lub sijhawm ntawm atoms yog ua ke nrog ib leeg thiab lawv taw tes rau tib qho kev taw qhia. Cov no yog tus ferromagnetic , ferrimagnetic thiab antiferromagnetic cov ntaub ntawv.

Tsis tas li ntawd, yuav ua li cas sib nqus domains? A sib nqus domain yog cheeb tsam uas lub Sib nqus teb ntawm atoms yog pawg ua ke thiab ua kom zoo. Tab sis, thaum cov hlau ua magnetized, uas yog dab tsi tshwm sim thaum nws yog rubbed nrog ib tug muaj zog hlau nplaum , txhua yam zoo li Sib nqus cov ncej lined thiab taw tes rau tib qho kev taw qhia. Cov hlau ua ib hlau nplaum.

Ntawm no, piv txwv li ferromagnetism yog dab tsi?

Ferromagnetism yog cov txheej txheem yooj yim uas qee cov ntaub ntawv (xws li hlau) tsim cov hlau nplaum ruaj khov, lossis nyiam cov hlau nplaum. Hauv physics, ntau yam sib txawv ntawm cov hlau nplaum yog qhov txawv. Ib hnub piv txwv ntawm ferromagnetism yog lub tub yees hlau nplaum siv los tuav cov ntawv ntawm lub qhov rooj tub yees.

Dab tsi tuaj yeem ua rau kev sib txuam ntawm cov khoom sib nqus hauv cov khoom siv?

Ferromagnetic cov ntaub ntawv ua magnetized thaum lub sib nqus domains nyob rau hauv lub khoom yog ua ke . Qhov no ua tau yuav ua tau los ntawm kev tso lub khoom nyob rau hauv lub zog sab nraud Sib nqus teb los yog hla hluav taws xob tam sim no los ntawm khoom . Ib txhia los yog tag nrho cov domains tau ua ua ke.
