Magnetism. Kev nyab xeeb pins, uas yog ua los ntawm cov hlau, raug nyiam mus rau ib lub hlau nplaum. Lub magnetic teb ntawm cov hlau nplaum induces ib tug me me magnetic teb nyob rau hauv lub steel pins, thiab cov opposite magnetic ncej tshaj nyiam ib leeg. Cov pins yuav nyob twj ywm magnetized rau ib lub sij hawm tom qab lub bar hlau nplaum tau raug tshem tawm.
Puas yog tus pin kev nyab xeeb nyiam rau cov hlau nplaum?
Qhov tseeb tsuas yog ob peb yam khoom raug nyiam rau cov hlau nplaum: txhua yam ua los ntawm hlau thiab qhov no suav nrog hlau, piv txwv li. kev ruaj ntseg pins thiab ntawv clips. Tsuas yog lwm ob hlau uas nyiam rau cov hlau nplaum tsis tshua muaj: cob alt thiab npib tsib xee. Cov khoom uas nyiam cov hlau nplaum yog hu ua cov khoom sib nqus.
Pob pins magnetic?
Steel pins stick to magnets. … Txawm li cas los xij, cov hlau nplaum yuav nyiam tus pin los ntawm qhov deb.
Puas yog tus pin hlau nplaum?
Tsis zoo li lwm cov xov xwm tumbling, Stainless Steel Txhaj Pins yog magnetic , uas ua rau kev sib cais yooj yim. Cov xov xwm no yog ua los ntawm cov hlau tsis muaj zog steelcov khoom siv ntxiv rau nws txoj kev ua neej ntev thiab ua haujlwm ntev.
Puas yog daim ntawv clip sib nqus?
paperclips tsis yog ib txwm sib nqus, yog li, ntawm lawv tus kheej, lawv yuav tsis lo ua ke los ua cov saw hlau. Txawm li cas los xij, los ntawm kev siv cov hlau nplaum, daim ntawv clips tuaj yeem ua hlau nplaum ib ntus. Cov hlau nyob rau hauv daim ntawv clip tuaj yeem sib nqus tau yooj yim tab sis yuav plam qhov hlau nplaum sai sai.
