Dab tsi yog txoj hauv kev zoo tshaj los daws cov hlau nplaum seem ntawm cov kab sib dhos?

Ib qho teeb meem ntxhov siab tshaj plaws hauv lub Hoobkas cov neeg ua haujlwm khiav mus rau thaum siv cov hlau nplaum hluav taws xob yog qhov txawv txav ntawm lub cev hu ua residual magnetism. Qhov zoo tshaj plaws, thaum koj tua hluav taws xob, lub tshuab yuav tsum tam sim ntawd tso cov hlau hnyav uas nws tsuas yog nqa. Txawm li cas los xij, tom qab ob peb lub hlis ntawm kev siv tas li txhua hnub, cov tub ntxhais hlau ntawm lub cuab yeej maj mam ua kom muaj zog mus tas li. Thaum lub zog raug txiav thaum kawg ntawm hnub kawg, lub zog sib nqus me me nyob tom qab. Qhov no txhais tau hais tias cov khoom sib zog ntawm cov ntawv hlau yuav nyob twj ywm tag nrho rau lub tuav electromagnet, yuam cov neeg ua haujlwm sib dhos taug kev thiab rub cov hlau ntse tawm ntawm tes. Qhov no rhuav tshem tag nrho qhov nrawm ntawm txoj kab sib dhos uas siv tau thiab kov yeej tag nrho lub hom phiaj ntawm kev muaj tes - pub dawb robotic system. Nws kuj tsim muaj kev nyab xeeb tseem ceeb rau cov neeg ua haujlwm.

Muaj ob peb txoj kev txhim khu kev qha los txhim kho qhov lingering stickiness ntawm lub Hoobkas hauv pem teb. Qhov kev txhim kho yooj yim tshaj plaws yog los lo ib daim nyias nyias ntawm cov khoom tsis yog- cov khoom sib nqus, xws li tooj dag shim lossis ib daim nplaum yas hnyav, ncaj qha rau ntawm lub ntsej muag hlau polished. Qhov no tsim qhov sib txawv me me uas txwv tsis pub cov hlau nplaum seem ntawm kev tuav mus rau cov khoom teeb. Rau kev txhim kho hluav taws xob ntau tshaj lij, ntau qhov kev tswj hwm qib siab ua kom muaj qhov rov qab polarity muaj nuj nqi. Thaum koj tig qhov hloov pauv kom poob lub load, lub kaw lus xa cov hluav taws xob me me rov qab los ntawm qhov tuav electromagnet rau ib feem ntawm ib pliag xwb. Qhov kev poob siab rov qab sai sai no tshem tawm cov khoom seem ntawm cov hlau nplaum thiab lav tias cov hlau hnyav poob tam sim ntawd yam tsis ua raws li cov tshuab. Ua raws li cov kev daws teeb meem yooj yim no ua rau koj cov khoom lag luam niaj hnub txav nrawm thiab nyab xeeb.
