Sib nqus zog , attraction los yog repulsion uas tshwm sim ntawm hluav taws xob nqi hais vim lawv cov lus tsa suab. Nws yog qhov yooj yim zog lub luag hauj lwm rau cov teebmeem xws li kev txiav txim ntawm hluav taws xob motors thiab cov attraction ntawm hlau nplaum rau hlau.
Tsis tas li ntawd, hom quab yuam yog hlau nplaum?
electromagnetic quab yuam
Tsis tas li ntawd, lub cim rau lub zog sib nqus yog dab tsi? Hauv electromagnetics, lo lus "magnetic field" yog siv rau ob qhov sib txawv tab sis zoo sib xws ntawm cov cim B thiab H. International System of Units , H, magnetic teb zog, yog ntsuas nyob rau hauv lub SI puag units ntawm ampere ib 'meter'.
Raws li txoj cai, dab tsi ua rau lub zog sib nqus?
Magnetism yog qhov zog exerted los ntawm cov hlau nplaum thaum lawv nyiam los yog tawm tsam ib leeg. Magnetism yog ua rau los ntawm kev txav ntawm cov nqi hluav taws xob. Txhua yam khoom yog tsim los ntawm cov khoom me me hu ua atoms. Txhua lub atom muaj cov khoom siv hluav taws xob, cov khoom uas nqa hluav taws xob.
Ob lub zog ntawm cov hlau nplaum yog dab tsi?
Cov zog tias a hlau nplaum exerts ntawm tej yam ntaub ntawv, nrog rau lwm yam hlau nplaum , yog hu ua magnetic zog . Cov zog yog exerted tshaj qhov deb thiab suav nrog zog ntawm attraction thiab repulsion. North thiab sab qab teb ncej ntawm ob hlau nplaum sib nyiam, thaum ob qaum teb los yog ob sab qab teb ncej teb ib leeg.

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Cov hlau nplaum ruaj khov puas poob hlau nplaum?
Yog lawm, nws muaj peev xwm ua tau rau cov hlau nplaum ruaj khov kom poob nws cov hlau nplaum. Muaj peb txoj hauv kev rau qhov no tshwm sim: 2) Ntawm qhov demagnetizing magnetic teb: cov hlau nplaum tas mus li nthuav tawm cov yam ntxwv hu ua coercivity, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv demagnetized los ntawm kev siv magnetic teb
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog qhov txawv ntawm lub zog siv zog thiab lub zog thauj khoom?
Raws li nrog cov dav hlau inclined, cov khoom yuav tsum tau txav mus los yog lub zog muaj zog los yog thauj khoom thiab kev siv zog yog lub zog muab tso rau hauv kev txav mus los ntawm lwm qhov kawg ntawm lub fulcrum
Dab tsi yog lub zog quab yuam hauv cov hlau nplaum?
Hauv hluav taws xob engineering thiab cov ntaub ntawv tshawb fawb, thecoercivity, tseem hu ua magnetic coercivity, coercivefield lossis coercive force, yog ib qho kev ntsuas ntawm lub peev xwm ntawm cov khoom siv ferromagnetic los tiv thaiv ib qho kev sib nqus sab nraud yam tsis tau demagnetized
