Nyob rau hauv lub siab hais tias tag nrho cov teeb meem yog tsim los ntawm elementary hais uas muaj ib spin, muaj magnetic teb rau txhua qhov teeb meem, tab sis nws tsuas yog yog tias cov molecules raug teeb tsa uas nws tuaj yeem tsim kom muaj nuj nqis los qhia qhov loj me me, xws li ferromagnets. Lub ntiajteb txawj nqus yog lub zog ntawm qhov, tsis yog ib yam, lossis qhov teeb meem.

Yog li ntawd, tib neeg puas tsim ib qho chaw sib nqus?

Biomagnetism yog qhov tshwm sim qhov twg magnetic teb yog tsim los ntawm cov khoom muaj sia, tshwj xeeb tshaj yog los ntawm tib neeg lub cev; (Sib txawv ntawm magnetic teb siv rau lub cev, hu ua magnetobiology).

Ib tug kuj yuav nug, dab tsi muaj magnetic teb? A magnetic teb yog ib vector teb uas piav txog cov Sib nqus cuam tshuam ntawm cov nqi hluav taws xob hauv cov txheeb ze kev txav thiab cov khoom siv hlau nplaum. Cov teebmeem ntawm magnetic teb feem ntau pom nyob rau hauv cov hlau nplaum ruaj khov, uas rub rau Sib nqus cov ntaub ntawv (xws li hlau) thiab nyiam los yog tawm tsam lwm yam hlau nplaum.

Ntawm no, puas tag nrho cov atoms muaj magnetic teb?

Txij li thaum tag nrho teeb meem yog tsim los ntawm atoms thiab tag nrho cov atoms muaj electrons uas nyob rau hauv motion, ua txhua lub atoms muaj magnetic teb ? Txij li thaum magnetic teb tsim los ntawm kev txav ntawm cov electrons nyob rau hauv opposite lus qhia, lawv ntxiv mus rau xoom. Zuag qhia tag nrho magnetic teb zog of atoms nrog tag nrho khub electrons yog xoom.

Cov hlau nplaum puas tuaj yeem pom los ntawm tib neeg lub qhov muag?

Magnetoreception (tseem magnetoception) yog ib qho kev nkag siab uas tso cai rau lub cev los ntes a magnetic teb kom pom kev taw qhia, qhov siab lossis qhov chaw. Tib neeg tsis xav tias muaj ib Sib nqus kev nkag siab, tab sis muaj protein ntau (lub cryptochrome) nyob rau hauv lub qhov muag uas ua tau ua haujlwm no.
