Paramagnetism, hom magnetism yam ntxwv ntawm cov khoom tsis muaj zog txaus nyiam los ntawm cov hlau nplaum muaj zog, muaj npe thiab tshawb xyuas los ntawm tus kws tshawb fawb Askiv Michael Faraday Michael Faraday English physicist thiab chemist Michael Faraday yog ib tus kws tshawb fawb loj tshaj plaws ntawm lub xyoo pua 19th. Nws ntau qhov kev sim ua rau muaj txiaj ntsig zoo rau kev nkag siab ntawm electromagnetism. https://www.britannica.com › biography › Michael-Faraday

pib hauv 1845. Feem ntau cov ntsiab lus thiab qee qhov sib txuas yog paramagnetic.
Lub hauv paus chiv keeb ntawm paramagnetism yog dab tsi?
Paramagnetism yog vim muaj qhov tsis sib xws ntawm cov khoom siv hluav taws xob hauv cov khoom, yog li feem ntau cov atoms tsis tiav atomic orbitals yog paramagnetic, txawm tias muaj kev zam xws li tooj liab. … Ib qho chaw sib nqus sab nraud ua rau cov hluav taws xob 'spins los ua kom sib npaug mus rau lub tshav pob, ua rau muaj kev ntxim nyiam.
Curie txoj cai ntawm paramagnetism yog dab tsi?
Raws li Curie txoj cai ntawm paramagnetism, lub zog ntawm magnetization nyob rau hauv tej yam khoom paramagnetic txawv inversely nrog rau qhov kub thiab txias siv rau cov khoom, uas txhais tau tias qhov kub ntawm paramagnetic ntau dua. cov khoom yog, qhov tsawg dua yuav magnetization nyob rau hauv cov khoom.
Puas yog tib neeg paramagnetic?
Al- txawm tias lub cev yeej muaj dia- thiab paramagnetictshuaj, peb yuav kaw peb tus kheej ntawm no rau ferromagnetic khoom; tshwj xeeb, peb yuav cuam tshuam nrog cov teb tsis tu ncua ntawm ferromagnetic hais, ua tom qab siv daim teb tau raug tshem tawm.
Lub ntsiab lus twg qhia qhov paramagnetism tshaj plaws?
Iron oxide, FeO, muaj tus nqi siab heev ntawm 720. Lwm cov ntaub ntawv suav tias muaj zog paramagnetic xws li hlau ammonium alum (66), uranium (40), platinum (26), tungsten (6.8), cesium (5.1), aluminium (2.2), lithium (1.4) thiab magnesium (1.2), sodium (0.72) thiab oxygen gas (0.19).
