Qhov Tseem Ceeb Qhov txawv - Dia vs Para vs Ferromagnetic Khoom

Raws li cov khoom sib nqus, cov ntaub ntawv tuaj yeem muab faib ua tsib pawg loj; diamagnetic, paramagnetic, ferromagnetic, ferrimagnetic thiab antiferromagnetic. Qhov sib txawv tseem ceeb ntawm diamagnetic, paramagnetic thiab ferromagnetic cov ntaub ntawv yog cov ntaub ntawv diamagnetic tsis nyiam mus rau sab nraud magnetic teb, thiab paramagnetic cov ntaub ntawv yog attracted rau sab nraud magnetic teb whereas ferromagnetic cov ntaub ntawv muaj zog attracted rau ib tug sab nraud magnetic teb.

Diamagnetic Materials yog dab tsi?

Diamagnetic cov ntaub ntawv yog cov ntaub ntawv uas tsis nyiam rau sab nraud magnetic teb. Qhov no yog vim hais tias cov atoms los yog ions nyob rau hauv cov ntaub ntawv no tsis muaj unpaired electrons. Yog li ntawd, cov ntaub ntawv diamagnetic yog repelled los ntawm magnetic teb. Qhov no tshwm sim vim hais tias qhov induced magnetic teb yog tsim nyob rau hauv cov ntaub ntawv no mus rau lub opposite kev taw qhia rau cov sab nraud magnetic teb. Qhov no induced magnetic teb ua rau cov creation ntawm ib tug repulsive quab yuam. Diamagnetism tuaj yeem pom hauv cov ntaub ntawv uas muaj symmetry ntawm cov qauv hluav taws xob thiab tsis muaj lub sijhawm sib nqus mus tas li. Thiab tseem, lub diamagnetism tsis nyob ntawm qhov kub thiab txias.

Qee yam piv txwv ntawm cov ntaub ntawv diamagnetic suav nrog;

1. Quartz (silicon dioxide)
2. YCalcite (calcium carbonate)
3. dej

Piv txwv li hauv quartz, muaj silicone atoms thiab oxygen atoms nyob rau hauv daim ntawv ntawm SiO_{2. Lub xeev oxidation ntawm Si atom yog +4, thiab lub xeev oxidation ntawm O atom yog -2. Yog li ntawd, tsis muaj cov electrons uas tsis tau ua ke hauv ob lub atoms.}

Cov Khoom Siv Paramagnetic yog dab tsi?

Paramagnetic cov ntaub ntawv yog cov khoom uas nyiam mus rau sab nraud magnetic teb. Qhov no tshwm sim vim hais tias cov ntaub ntawv no muaj unpaired electrons nyob rau hauv lub atoms los yog ions nyob rau hauv cov ntaub ntawv no. Cov hluav taws xob tsis sib xws no tuaj yeem tsim kev sib nqus sib nqus.

Daim duab 02: Garnet

Cov ntaub ntawv Paramagnetic tuaj yeem sib cais los ntawm lwm cov ntaub ntawv siv cov khoom siv sib nqus sib nqus sib nqus. Cov kev sib cais no siv cov hlau nplaum nrog lub zog ntawm 0.2-0.4 Tesla. Qee qhov piv txwv ntawm cov ntaub ntawv paramagnetic suav nrog;

1. Ilmenite (FeTiO₃₎
2. Hematite (Fe₂O₃₎
3. Chalcopyrite (CuFeS₂₎
4. Garnet (Fe-silicates)

Cov khoom siv Ferromagnetic yog dab tsi?

Cov ntaub ntawv ferromagnetic yog cov ntaub ntawv uas nyiam nyiam rau sab nraud magnetic teb. Cov ntaub ntawv no muaj ntau dua unpaired electrons nyob rau hauv lawv cov hlau atoms los yog hlau ions. Thaum cov ntaub ntawv zoo li no tau nyiam mus rau qhov chaw sib nqus sab nraud, lawv tau txais cov hlau nplaum sib nqus thiab tuaj yeem coj tus cwj pwm zoo li cov hlau nplaum me me. Hauv kev lag luam nplai, cov ntaub ntawv ferromagnetic raug cais los ntawm lwm cov ntaub ntawv siv cov khoom siv sib nqus sib nqus uas siv cov hlau nplaum nrog 0.04 Tesla.

Daim duab 03: Magnetite

Qhov sib nqus sib nqus feem ntau yog induced magnetic yob separator. Qee qhov piv txwv ntawm cov ntaub ntawv ferromagnetic suav nrog;

1. Magnetite (Fe₃O₄) - muaj ob qho Fe²⁺ thiab Fe^{3+ Ob lub ions no muaj cov electrons tsis sib xws.}
2. Iron (Fe)

Summary – Dia vs Para vs Ferromagnetic Materials

Cov ntaub ntawv diamagnetic tau yooj yim sib cais los ntawm lwm cov ntaub ntawv vim tias lawv pom muaj zog ntawm cov hlau nplaum. Cov ntaub ntawv paramagnetic thiab cov ntaub ntawv ferromagnetic tuaj yeem sib cais los ntawm kev siv cov hlau nplaum sib nqus sib nqus los ntawm kev hloov lub zog ntawm cov hlau nplaum siv hauv cov khoom sib nqus. Qhov sib txawv ntawm diamagnetic, paramagnetic thiab ferromagnetic cov ntaub ntawv yog cov ntaub ntawv diamagnetic tsis nyiam mus rau sab nraud magnetic teb, thiab paramagnetic cov ntaub ntawv yog attracted rau sab nraud magnetic teb whereas ferromagnetic cov ntaub ntawv muaj zog attracted rau sab nraud magnetic teb.
