: muaj qhov sib nqus permeability tsawg dua li lub tshuab nqus tsev: me ntsis repelled los ntawm cov hlau nplaum.
Diamagnetism txhais li cas?
/ (ˌdaɪəˈmæɡnɪˌtɪzəm) / npe. qhov tshwm sim tshwm sim los ntawm cov tshuaj uas muaj cov txheeb ze permeability tsawg dua kev sib koom ua ke thiab qhov cuam tshuam tsis zoo. Nws yog tshwm sim los ntawm lub orbital motion ntawm electrons nyob rau hauv lub atoms ntawm cov khoom thiab yog unaffected los ntawm kub Piv ferromagnetism, paramagnetism.
Diamagnetism nrog piv txwv yog dab tsi?
Diamagnetic cov ntaub ntawv yog cov cov khoom uas txhua tus electrons tau ua khub thiab tsis muaj electrons muaj dawb. Piv txwv li, ntoo, tooj liab, kub, bismuth, mercury, nyiaj, lead, neon, dej, thiab lwm yam. Superconductors yog cov khoom zoo meej diamagnetic vim lawv tshem tawm tag nrho cov sab nraud magnetic teb.
Diamagnetism siv rau dab tsi?
Cov hlau nplaum superconducting yog cov ntsiab lus tseem ceeb ntawm feem ntau magnetic resonance imaging (MRI)cov tshuab thiab yog cov kev siv tseem ceeb tshaj plaws ntawm diamagnetism. Bismuth, uas yog siv nyob rau hauv cov phom, qhia txog qhov muaj zog diamagnetism. Bismuth tuaj yeem yaj thiab molded kom ntes txhua yam khoom diamagnetic.
Diamagnetic thiab paramagnetic yog dab tsi?
Thaum twg ob lub tshuab hluav taws xob ua ke ua ke hauv lub orbital, lossis lawv tag nrho cov spin yog 0, lawv yog diamagnetic electrons. Atoms nrog tag nrho cov diamagnetic electrons yog hu ua diamagneticatoms. A paramagnetic electron yog ib qho hluav taws xob tsis sib xws. Ib qho atom raug suav tias yog paramagnetic yog tias txawm tias ib lub orbital muaj qhov sib npaug.
