Electromagnetic induction yog ib qho kev nthuav dav heev. Nws tuaj yeem siv los tua cov drones lossis recharge gadgets. Dab tsi lom zem technologies ntawm peb lub sij hawm yog txuam nrog electromagnetic induction?
Koj tuaj yeem ya tau ntev npaum li cas? "Txog thaum muaj roj txaus," hais tias tus neeg nyiam dav hlau. "Txog thaum lub roj teeb tag," hais tias tus tswv ntawm ib lub drone fashionable. "Ntau npaum li koj nyiam," hais Samer Aldhaher ntawm Imperial College London. Ua kom pom qhov muaj peev xwm ntawm kev siv hluav taws xob xa hluav taws xob wireless, tus kws kho mob tuaj yeem hloov kho yooj yim ntawm cov khoom me me quadcopter yuav hauv khw thiab tshem tawm cov roj teeb onboard los ntawm nws. Hloov chaw, ib qho yooj yim kauv ntawm tooj liab daim kab xev yog ntsia rau ntawm lub drone - nyob ze rau qhov inducing tooj liab kauj, lub cuab yeej tseem nyob rau hauv huab cua ntev npaum li koj nyiam.
Tus tsim ntawm Aldracher system yog qhov yooj yim heev, tab sis txawm tias yooj yim dua - ib qho cuab yeej rau kev ua kom pom hluav taws xob induction nyob rau hauv wireless xa hluav taws xob, lub rooj sib txoos uas tau qhia hauv YouTube video ntawm Ludic Science channel. Txhawm rau ua rau lwm tus xav tsis thoob, nyiam tus menyuam: txhua yam uas xav tau yog lub kauj ntawm tooj liab, lub transistor, lub roj teeb uas peb yuav hloov lub zog, thiab LED uas peb yuav sim teeb. Tag nrho cov ntsiab lus tau piav qhia hauv daim vis dis aus, thiab tsis txhob ntshai tias nws yog lus Askiv, daim duab kos yog qhov yooj yim dua.
Nws yog ib qho kev txaj muag uas cov tshuab yooj yim no tsis muaj txiaj ntsig zoo: lub tshuab hluav taws xob induction faib lub zog tsis yog kev taw qhia, thiab tus tsov ntxhuav feem ntawm nws tau ploj mus yam tsis tau ncav cuag lub cuab yeej raug them. Txawm li cas los xij, radiophysicists nrhiav txoj hauv kev zoo tshaj plaws los hla qhov kev txwv no. Piv txwv li, Ossia tab tom txhawb wireless "chargers" ua rau hauv phab ntsa lossis ua cov khoom siv dawb - thiab muaj peev xwm them taus txawm tias lub gadget muaj zog tshaib plab li iPhone. Ib qho tshwj xeeb module ntawm lub smartphone nws tus kheej xa tawm cov teeb liab tsis muaj zog, qee qhov (ob qho tib si ncaj qha thiab los ntawm kev xav los ntawm cov khoom nyob ib puag ncig) poob rau ntawm cov khoom siv them nyiaj thiab tso cai rau koj los txiav txim siab txoj haujlwm ntawm lub smartphone hauv qhov chaw. Tus so yog qhov teeb meem ntawm kev siv thev naus laus zis: cov lus teb high-zog pulses raug xa mus rau tib cov lus qhia nyob rau hauv qhov kev coj rov qab, nrog rau zaus ntawm 100 Hz.
Zoo, kom tau mus rau hauv qab heev thiab nrhiav seb cov cuab yeej zoo li no ua haujlwm li cas, tsis muaj dab tsi zoo dua li saib cov yeeb yaj kiab qub. 20-feeb nrov science zaj duab xis "Electromagnetic induction". Tshaj tawm xyoo 1978 ntawm Lennauchfilm, nws tsis yog qhov qub, ib yam li cov cai ntawm physics tsis tau laus.

Peb yuav yeej li cas. Cov xov xwm Fab Kis xav tsis thoob los ntawm Lavxias nrhiav tub sab hauv Paris
Lub festering lub koob npe nrov ntawm lub sub-Parisian suburb ntawm Saint-Denis tau ntev dhau lub koob meej ntawm tag nrho cov "rookeries" thiab "raspberries". Thiab txhua tus neeg Fabkis paub zoo tias txawm nyob hauv nruab hnub nrig, yog tias koj nres ntawm lub teeb tsheb, txhua lub qhov rooj ntawm koj lub tsheb yuav tsum kaw, thiab lub qhov rais tsa, tsis muaj ib qho tawg
Peb txheej ntawm tib neeg kev tshawb fawb: kev xav, kev xav thiab kev paub
Tsuas yog nrog kev pab ntawm intuition, ib tug neeg tuaj yeem nkag siab qhov sib txawv ntawm kev txawj ntse, kev xav thiab kev xav ntawm tus ntsuj plig. Logic yog li cas lub siab paub qhov tseeb; intuition - yuav ua li cas cov kev muaj tiag, ntsuj plig
Hloov chaw ntawm kev kawm thiab kev paub, kev tsis paub thiab kev tsis muaj peev xwm kis tau
Muaj ib tug loj mythology txuam nrog kev kawm ntawv thiab qhia txog kev paub. Lawv nthuav dav lub qab ntug, ua kom muaj peev xwm txhim kho lawv txoj kev xav, tsim ib tus neeg muaj peev xwm, ntxiv nws rau txhua qhov kev nplua nuj ntawm kab lis kev cai. Tab sis lub dav ramified systems ntawm kev kawm loj ntawm lub xyoo pua nees nkaum muab tso rau hauv lub conveyor tso tawm, raws li lub sij hawm muab tso rau hauv kev siv los ntawm Solzhenitsyn, "kev kawm", cov kws tshwj xeeb uas tsis paub dab tsi tab sis lawv cov lag luam
Tsis pub leejtwg paub patrons ntawm ob lub kiv puag ncig thiab kev tsov kev rog nyob rau hauv Russia
Thaum lub Cuaj Hlis 2008, lub tswb nrov ntawm St. Daniel's Monastery rov qab los ntawm Asmeskas lub nroog Harvard mus rau Moscow. Raws li koj paub, cov tswb no raug coj tawm ntawm Russia xyoo 1930 los ntawm Asmeskas tus thawj coj Charles Richard Crane. Tawm tswv yim txog kev xa rov qab ntawm lub tsev teev ntuj tswb rau lawv lub tebchaws, cov xov xwm Lavxias tau hais meej tias Crane "txuag lub tswb ntawm kev puas tsuaj." Leej twg yog Charles Richard Crane?
Neurosurgeon: kev nco qab tsis muaj qhov chaw hauv lub cev, thiab kev sib txuas ntawm lub hlwb thiab kev xav yog qhov tsis paub tob
Academician, lub taub hau ntawm lub neurosurgical department ntawm Republican Scientific thiab Practical Center rau Neurology thiab Neurosurgery, neurosurgeon Arnold Fedorovich Smeyanovich rau 47 xyoo ntawm kev xyaum tau ua lub hlwb phais nyob rau hauv yuav luag 9000 tus neeg mob
