1. Cov hlau nplaum mos tsis muaj qhov "magnifying iav" muaj nuj nqi, tab sis vim nws yog tus neeg xyuas pib zoo ntawm cov hlau nplaum, nws tuaj yeem sib sau ua ke ntawm cov hlau nplaum nyob ze, uas yog, qhov chaw sib nqus nyob ze yog distorted, lub magnetic teb nyob rau hauv lwm yam. qhov chaw ua sparse, thiab nws lub zog magnetic teb hloov nrog lub zog ntawm sab nraud magnetic teb.
2. Cov hlau nplaum mos teb rau cov nthwv dej electromagnetic, tab sis cov lus teb amplitude nws txawv nrog ntau zaus. Yog tias qhov zaus yog siab, cov lus teb me me.
3. Hluav taws xob thiab hlau nplaum yog sib cais. Muaj ib qho chaw sib nqus nyob ib ncig ntawm lub teb hluav taws xob thiab rov ua dua. Nws ua tau manifests nws tus kheej nyob rau hauv daim ntawv ntawm ib tug concentrated magnetic teb.
