twg magnetic teb yog qhov muaj zog tshaj

Lub zog ntawm cov hlau nplaum feem ntau yog ntsuas hauv chav ntawm Gauss lossis Tesla. Ib Tesla yog sib npaug rau 10,000 Gauss. Muaj ob hom hlau nplaum thaum nws los txog rau magnetic teb: cov hlau nplaum ruaj khov thiab electromagnets. Cov hlau nplaum tas mus li, raws li lawv lub npe implies, muaj ib qho chaw sib nqus mus tas li uas ib txwm muaj. Electromagnets, ntawm qhov tod tes, tsim cov hlau nplaum tsuas yog thaum muaj hluav taws xob dhau los ntawm lawv.

Uas tau hais tias, cov hlau nplaum ruaj khov tuaj yeem muaj qhov sib nqus zoo dua li cov hlau nplaum ntawm tib qhov loj. Qhov no yog vim qhov sib nqus ntawm cov hlau nplaum tas mus li yog ib qho khoom muaj nqis ntawm cov khoom nws yog tsim los ntawm, whereas lub zog ntawm ib tug electromagnet yog nyob ntawm tus nqi ntawm cov tam sim no ntws los ntawm nws.

Cov hlau nplaum ruaj khov tshaj plaws paub yog cov hlau nplaum neodymium. Cov hlau nplaum no yog tsim los ntawm cov hlau nplaum ntawm neodymium, hlau, thiab boron, thiab tuaj yeem muaj lub zog hlau nplaum txog li 1.5 Tesla. Lawv yog siv nyob rau hauv ntau yam kev siv, xws li hluav taws xob motors, generators, thiab magnetic resonance imaging (MRI) tshuab.

Electromagnets kuj tuaj yeem muaj qhov sib nqus muaj zog, tab sis lawv lub zog yog nyob ntawm tus nqi tam sim no uas ntws los ntawm lawv. Qhov muaj zog tam sim no, qhov muaj zog ntawm magnetic teb. Electromagnets yog siv rau ntau yam kev siv, xws li nqa cov khoom hnyav, lub zog hais lus, thiab hauv MRI tshuab.
