Yintoni kuFacebook ngoku

Ukuthetha ngento na ngoku eyabangelwa, akunakwenzeka ukuba ukukhumbula ukucikideka le yamachiza enkulu yexesha lakhe - Michael Faraday. Eneneni, ngokwenxalenye ngenxa yomsebenzi wakhe namhlanje, singakwazi sonke kunandipha iingenelo impucuko ezifana nombane. Emva koko, ngenkulungwane ye-19, izinto imichiza (neebhetri) ngumthombo kuphela wamandla ombane. Emva experiments Faraday ihlabathi waba ezifumanekayo umbane, leyo zatshintsha imbali liphela kwixesha elizayo.

Phambi ko 1831 yemvelo babeyazi ubukho zombane kunye ngemagnethi. Oku kwakukholelwa ukuba intsebenziswano ezinamanqwanqwa amabini okanye ngaphezulu iintlawulo (electron okanye ion) yenza uhlobo oluthile kwempixano - yasendle yombane. Kodwa amacala mobile ezinxulumene amasimi ngemagnethi. Kucacile ukuba lo gama kukho zonke zinto zifuneka kuqala ukuze ukufunyanwa, yaye akukho mfuneko yokuba ulinde ixesha elide.

yoqheliso magnetic kwaye yoqheliso ngoku yabhaqwa ngo 1831 phantse ngexesha elinye zizazinzulu-ziingcali ezimbini - Faraday no Henry. Okumangalisayo kukuba, efanayo kwenzeka kuzo zonke iinkalo zobunjineli yombane (umzekelo, i "uyise" mpikiswano radio kangaka kude). Njengoko Faraday kuqala yapapashwa iziphumo zovavanyo kunye nentsingiselo wabo kubo, loo nto ixela ukuba discoverer ye isenzeko ebizwa ngokuba "induction yangoku."

Enye yemifuniselo ukuba ukurhwaphilizela kubo ubukho amandla (ngumtshangatshangiso yombane ngu inkcazelo Isazinzulu) ukuba sidalwe kumqhubi yangoku. Ukususela emancamini omabini malunga yentonga yesinyithi inxeba eyeka ezimbalwa wire. Izigqibo kwelinye icala eqhagamshelwe galvanometer, yaye kwelinye icala ukuya wire ke umbane evela kwi ibhetri. Ngexesha galvanometer ukubandakanywa battery kwabhalwa imbonakalo okwexeshana umsinga wombane. Oku kwenzeke xa amandla icinyiwe. Ingqikelelo senziwe malunga inkangeleko ethile intsimi amandla ukuvelisa yangoku.

La mava elilandelayo eyaziwa: ukuba nezigqibo Ikhoyili encinane lalibonelelwa evela ombane ibhetri, kwaye ajike lokumpompoza yangoku. Uye wangena kubude umbindi jiko ngaphezulu, ekupheleni leyo idityaniswe galvanometer. Xa nokukha kunye nokwazisa kwi isixhobo coil kwabhalwa imbonakalo amasuntswana icala wayalela motion. Le nto ke iye ngokuba yoqheliso magnetic, kunye nentshukumo kwamasuntswana kuthiwa "uqhutyelwe lwangoku".

Kwathi kanti, unobangela yinto magnetic (magnetic field) imigca leyo abawela ngengxabano umqhubi. Amandla ngoku wayenga kuxhomekeke rhoqo kule kona. Ngaphezu koko, andinjalo siseko, ukuba umgca umbhexeshi i iwela ngobunzulu ukuba intsimi ngokwayo esijikeleziswa okanye lo mhlaba otsalayo utshintsha (umzekelo, ngamandla wayo ezahlukeneyo kwi ulwazi lokuqala).

ulwalathiso kuFacebook ngoku kwi umqhubi nayo hayi ngengozi. Yinto eyaziwayo ukuba ngeenxa nayiphi na umqhubi apho umsinga wombane, imagnethi ekhoyo kunye imigca yalo kwempixano. Ukuziqhelanisa kwabo kuxhomekeke ulwalathiso intshukumo yangoku.

Apha umqhubi yaziswa imagnethi kulo phambi yomtya evaliweyo uyacengeka yi isindululo kwamasuntswana icala. Ngokusekelwe kwiipropati ekhoyo ehlabathini umqhubi kukho lentsimi yayo ngemagnethi. Ngaphezu koko, line yayo ukugogeka wayalela ngendlela efana ukuvala utshintsho kunokwenzeka endle zaseprayimari, ebangela isizukulwana lokuqala kuFacebook yangoku.

Enyanisweni, intsimi zasesekondari ayikho "vumela" utshintsho zaseprayimari. Ukuba uyakhumbula isakhiwo atom ngayo izinto eziphathekayo, kuquka ukuhamba zesinyithi, iba physics ngokucacileyo le meko: ngumongo ion ukutsala electron ezilahlekileyo ukuze kubuyiselwe imeko yayo sokuqala yokuphumla. Ngenxa yokwanda ezinkulu "enkqonkqoza phandle" electron amandla enomtsalane ifuna 'ukubuyekeza' impembelelo lwangaphandle. Ngako oko, xa ukunciphisa endle emhlabeni lesibini zibangelwa intshukumo amasuntswana kwi umqhubi uyasixhasa.
