Magnetism yog lub zog tseem ceeb hauv qhov xwm txheej uas ua lub luag haujlwm tseem ceeb hauv ntau yam kev tshawb fawb thiab thev naus laus zis. Hauv plawv ntawm magnetic phenomena yoghlau nplaum, tshwj xeebmuaj zog hlau nplaum, uas muaj cov khoom tshwj xeeb uas tuaj yeem muab faib ua xya hom sib nqus sib txawv. Kev nkag siab txog cov hom no tuaj yeem txhim kho peb txoj kev nkag siab ntawm cov hlau nplaum muaj zog ua haujlwm thiab lawv cov kev siv hauv lub neej txhua hnub.
1. Ferromagnetism: Qhov no yog hom hlau nplaum feem ntau, thiab cov ntaub ntawv xws li hlau, cobalt, thiab npib tsib xee muajmuaj zog hlau nplaum. Cov hlau nplaum muaj zog ua los ntawm cov ntaub ntawv no tuaj yeem khaws lawv cov hlau nplaum txawm tias tom qab cov hlau nplaum sab nraud ploj mus.
2. Paramagnetic: Nyob rau hauv hom no, cov khoom muaj ib tug tsis muaj zog attraction rau lub magnetic teb. Tsis zoo li cov ntaub ntawv ferromagnetic, cov tshuaj paramagnetic tsis khaws lawv cov hlau nplaum tom qab sab nraud magnetic teb ploj.Cov hlau nplaum muaj zogtuaj yeem cuam tshuam cov ntaub ntawv no, tab sis cov nyhuv yog ib ntus.
3. Diamagnetism: Tag nrho cov ntaub ntawv muaj ib co degree ntawm diamagnetic zog, uas yog ib tug tsis muaj zog daim ntawv ntawm magnetism. Cov hlau nplaum muaj zog tuaj yeem tua cov ntaub ntawv diamagnetic, qee zaum ua rau lawv levitate, nthuav tawm qhov kev sib cuam tshuam zoo ntawmsib nqus rog.
4. Antiferromagnetism: Nyob rau hauv cov ntaub ntawv antiferromagnetic, lub sij hawm sib nqus sib nqus nyob ib sab yog ua raws li cov lus qhia rov qab, tshem tawm ib leeg tawm. Qhov no ua rau tsis muaj net magnetization txawm nyob rau hauv lub xub ntiag ntawm ahlau nplaum muaj zog.
5. Ferrimagnetism: Zoo ib yam li antiferromagnetism, cov ntaub ntawv ferrimagnetic muaj qhov sib txawv ntawm lub sijhawm sib nqus, tab sis lawv tsis sib npaug, ua rau muaj kev sib nqus hlau nplaum. Cov hlau nplaum muaj zog tuaj yeem cuam tshuam nrog cov ntaub ntawv no, ua rau lawv siv tau ntau yam kev siv.
6. Superparamagnetism: Qhov tshwm sim no tshwm sim hauv me me ferromagnetic los yog ferrimagnetic nanoparticles. Thaum raug cov hlau nplaum muaj zog, cov khoom no nthuav tawm cov hlau nplaum uas muaj suab npe, thaum tsis muaj qhov sib nqus, cov hlau nplaum ploj.
7. Supermagnetic: Hom no piav txog cov ntaub ntawv uas ib txwm tsis yog hlau nplaum tab sis ua cov hlau nplaum thaum raug cov hlau nplaum muaj zog.
Hauv kev xaus, kev kawm magnetism, tshwj xeeb tshaj yog los ntawm lub lens ntawm cov hlau nplaum muaj zog, qhia txog lub ntiaj teb complex thiab fascinating. Txhua hom hlau nplaum muaj cov khoom tshwj xeeb thiab cov ntawv thov uas yog qhov tseem ceeb rau kev nce qib hauv kev siv tshuab thiab cov ntaub ntawv tshawb fawb. Kev nkag siab txog cov hom no yuav tsis tsuas yog txhim kho peb txoj kev paub txog kev sib nqus phenomena tab sis kuj qhib qhov rooj rau kev siv tshiab ntawm cov hlau nplaum muaj zog hauv ntau qhov chaw.
