Txoj kab ntsuab yog qhov kev poob qis sib npaug ntawm xoom thiab cov kev taw qhia ntawm Tseeb North thiab Sib Nqus Sib Nqus North Sib Nqus Sab Nraud Raws li tus qauv WMM tam sim no, 2020 qhov chaw ntawm sab qaum teb sib nqus ncej yog 86.50 ° N thiab 164.04 ° Ethiab sab qab teb magnetic ncej yog 64.07 ° S thiab 135.88 ° E. https://www.ngdc.noaa.gov › geomag › GeomagneticPoles

yog sib npaug (kab mob siab). Sib Nqus North thiab South Ncej yog qhia los ntawm lub voj voog ntsuab.
Zoo kab ntawm kev poob qis yog dab tsi?
Thaum ob tug ncej sib dhos, kev poob qis yog xoom, thiab txoj kab ntawm xoom poob yog hu ua kab mob siab Ntawm cov ntsiab lus sab hnub poob ntawm txoj kab mob siab, ib rab koob sib nqus yuav taw rau sab hnub tuaj ntawm qhov tseeb sab qaum teb (positive declination). Ntawm cov ntsiab lus sab hnub tuaj ntawm txoj kab kev nyuaj siab, ib rab koob sib nqus yuav taw tes rau sab hnub poob ntawm qhov tseeb sab qaum teb (tsis pom kev tsis zoo).
qhov kev tsis lees paub nyob qhov twg?
Kev poob qis yog ntsuas qaum teb lossis sab qab teb los ntawm txoj kab hluav taws xob xilethi-aus, raws lub voj voog teev dhau los ntawm nqe lus nug.
Puas declination txhais tias poob?
Kev poob qis ntawm sab qaum teb xilethi-aus ncej yog 90 ° thiab qhov poob ntawm sab qab teb xilethi-aus ncej yog -90 °. … Ib qho kev tsis txaus siab kuj tuaj yeem yog qhov tsis lees paub, tshwj xeeb tshaj yog nyob rau hauv qhov xwm txheej raug cai lossis raug cai. Nyob rau hauv qhov kev txiav txim no, nws yog ib tug npe daim ntawv ntawm qhov kev poob qis, lub ntsiab lus tsis kam lossis tig ib yam dab tsi
Lub ntiaj teb nyob qhov twg tsis muaj qhov sib nqus declination?
Ntiaj teb zoo li lub hlau nplaum loj heev nrog rau sab qaum teb thiab South Ncej. Txawm li cas los xij, cov hlau nplaum North thiab South Ncej tsis ua raws li Geographic North thiab South Ncej.
