Sib nqusFlus Φ
Lub ntsiab txhais ntawm magnetic flux physics yog tus naj npawb ntawm magnetic teb kab perpendicular rau ib cheeb tsam. Peb qhov kev nkag siab yooj yim yog qhov ntsuas lub cev ntsuas qhov loj me me, chav tsev yog Wb, qhia los ntawm Φ, Φ=B × S, B stands rau magnetic induction intensity, S stands rau magnetic ncej cheeb tsam, uas yog hais. , qhov loj ntawm magnetic flux nyob ntawm qhov chaw sib nqus ncej thiab sib nqus induction siv.
Lub flux ntsuas ntsuas yog flux meter. Nrog Helmholtz kauj, tsis tsuas yog cov flux tuaj yeem ntsuas tau, tab sis kuj tseem tuaj yeem ntsuas lub sijhawm sib nqus, vim tias qhov ntsuas tus nqi ntawm cov flux yuav hloov nrog qhov ntsuas ntawm qhov ntsuas flux thiab Helmholtz kauj. Qhov sib nqus flux thiab lub sijhawm sib nqus, nws zoo li qhov sib txawv ntawm qhov hnyav thiab qhov hnyav, qhov hnyav yog cuam tshuam los ntawm qhov gravitational tas li, tib yam khoom hauv ntiaj teb thiab Mars muaj qhov hnyav sib txawv, tab sis qhov hnyav yog tib yam. Kev cuam tshuam los ntawm tus naj npawb ntawm cov kauj hloov, qhov sib nqus flux ntawm tib lub hlau nplaum ntsuas los ntawm cov fluxometers sib txawv thiab cov coils yuav txawv, tab sis lub sijhawm sib nqus yuav tsum yog tib yam.
Thaum cov hlau nplaum nyob rau hauv lub xeev qhib, qhov tseeb remanence tus nqi Bdi (tseem hu ua intrinsic flux density) sib haum mus rau qhov chaw ua hauj lwm yuav xam tau los ntawm kev siv txoj kev sib nqus flux conversion. Bdi =Φ* coil permanence/magnet volume.
