Lamulo la Faraday

Kukhazikitsa malamulo a Faraday

Michael Faraday anali wasayansi yemwe anali ndi gawo lalikulu pantchito za sayansi. Tithokoze katswiriyu, zinthu zambiri zomwe timagwiritsa ntchito masiku ano zimayendetsedwa ndi Lamulo la Faraday. Kulowetsa pamagetsi ndi njira yomwe magetsi amatha kuyambitsidwa ndikusintha kwamaginito. Kulowetsa kwamagetsi uku ndikogwirizana mwachindunji ndi lamulo la Faraday.

Munkhaniyi tikukuwuzani zamakhalidwe onse ndikufunika kwamalamulo a Faraday.

Makhalidwe apamwamba

munda wamagetsi

Pali mitundu yosiyanasiyana ya mphamvu zomwe zimayendetsa maginito. Mphamvu yomwe imakumana ndi waya yomwe imadutsa mtsinje ndi chitsanzo chapadera cha malamulo a Faraday. Poterepa, mphamvu yomwe waya amakumana nayo kudzera pamagetsi imatheka chifukwa cha ma elekitironi omwe akuyenda kapena pamaso pa maginito. Izi zimachitikanso kwina. Titha kusuntha waya kudzera pamagetsi kapena kusintha kukula kwa maginitowo pakapita nthawi ndipo zimatha kuyambitsa magetsi.

Lamulo lofunikira kwambiri kuti athe kufotokoza kulowetsedwa kwamagetsi ndi lamulo la Faraday. Anadziwika ndi Michael faraday ndipo imayesa ubale womwe ulipo pakati pa maginito osintha kwakanthawi ndi magetsi omwe amapangidwa ndikusintha. Tikapita kumalamulo a Faraday timawona kuti ili ndi mawu awa:

"Mphamvu yamagetsi yoyenda mozungulira yotsekedwa imafanana molingana ndi kuchuluka kwa kusintha kwa nthawi yamagetsi yomwe imadutsa pamtunda uliwonse ngati dera lokha ngati m'mphepete mwake."

Kuwonetsera kwamalamulo a Faraday

Kutulutsa kwamagetsi

Tikuwonetsa zomwe lamulo la Faraday likunena ndi chitsanzo. Tiyeni tiwunikenso zoyeserera za Faraday. Apa tili ndi batire lomwe limayang'anira ntchito yamagetsi ku koilo yaying'ono. Ndi gawo lamagetsi lamagetsi maginito amapangidwa kudzera potembenuka kwa koyilo. Koyilo pali zingwe zachitsulo bala pa olamulira ake. Chophimbacho chikamalowa ndikutuluka chachikulu, chimakhala ndi maginito omwe amapanga magetsi mkati mwa koyilo. Mphamvu iyi imatha kuyezedwa ndi galvanometer.

Kuchokera pakuyesaku, malamulo a Faraday atha kupangidwa ndikupeza mayankho ambiri. Zotsatira zonse za kuyesaku zidakhudzana ndikupanga mphamvu zamagetsi ndipo ndizofunikira pamalamulo a Lenz, omwe amagwiritsidwa ntchito potengera magetsi amakono kwambiri omwe tili nawo masiku ano.

Tiyeni tiwone mwachidule nkhani ya Michael Faraday yomwe adatha kukhazikitsa lamuloli. Tikudziwa kuti wasayansi uyu Iye ndiye adayambitsa malingaliro apakati pamagetsi ndi maginito. Adadzipereka kuti afufuze za sayansi iyi. Anali wokondwa kwambiri pomwe wasayansi waku Danish wotchedwa Oersted adatha kuwonetsa mwamphamvu ubale womwe ulipo pakati pamagetsi ndi maginito. Izi zidachitika mchaka cha 1820. Poyesa izi adatha kutsimikizira kuti waya yomwe ikuchitika pakadali pano imatha kusuntha singano yomwe inali ndi maginito kwathunthu komanso kuti anali mkati mwa kampasi.

Faraday adatha kupanga zoyeserera zingapo. Chimodzi mwazinthuzo chinali chophatikizira ma waya awiri ozungulira mphete yachitsulo. Kuti muwone ubale womwe ulipo pakati pa magetsi ndi maginito, adadutsa mphamvu yamagetsi kudzera pa imodzi mwa ma solenoid kudzera pa switch. Zamakono zinapangidwira mzake. Faraday akuti mawonekedwe amagetsi amayenda chifukwa cha kusintha kwa maginito komwe kumachitika pakapita nthawi.

Zotsatira zake, chifukwa cha kuyesaku, a Michael Faraday adatha kuwonetsa ubale womwe ulipo pakati pa maginito ndi magetsi. Zambiri zimachokera pazonsezi zomwe zidakhala gawo lamalamulo a Maxwell.

Malamulo ndi zitsanzo za Faraday

lamulo la faraday

Kuti tipeze ubale pakati pa maginito ndi magetsi, njira iyi ikuperekedwa.

EMF (Ɛ) = dϕ / dt

Komwe EMF kapena Ɛ imayimira Electromotive Force (the voltage), ndipo dϕ / dt ndiye kusiyanasiyana kwakanthawi kwa maginito ϕ.

Zinthu za tsiku ndi tsiku monga uvuni wamagetsi zimatheka chifukwa cha lamulo la Faraday. Tidzawona zina mwa zitsanzo za kugwiritsa ntchito malamulo a Faraday m'moyo watsiku ndi tsiku. Tikudziwa zimenezo pafupifupi ukadaulo wonse wamagetsi womwe tili nawo lero watengera lamulo la Faraday. Makamaka, ndikofunikira pankhani yazida zonse zamagetsi monga ma jenereta, ma transformer ndi ma motors amagetsi. Tiyeni tipereke chitsanzo: kuti tithe kupanga makina apompopompo, chidziwitsocho chimatengera kugwiritsa ntchito diski yamkuwa yomwe imazungulira kumapeto kwa maginito. Chifukwa cha kayendedwe kazungulira kameneka, makanema enieni amatha kupangidwa.

Kuchokera pamfundo iyi pakubwera kupangidwa konse kwa zinthu zovuta monga thiransifoma, chosinthira chamakono cha jenereta, maginito ananyema kapena mbaula yamagetsi.

Kulumikizana pakati pa kupatsidwa ulemu ndi mphamvu yamaginito

Tikudziwa kuti maziko a malamulo a Faraday ndi ovuta. Kukhala wokhoza kudziwa kumvetsetsa kwamalingaliro kokhudzana ndi kulumikizana komwe kulipo ndi mphamvu yamaginito pama tinthu omwe ali ndi vuto ndikosavuta. Mwachitsanzo, kulipiritsa kwa waya wosuntha. Tikuyesera kufotokoza kulumikizana pakati pamagetsi ndi mphamvu yamaginito. Timaganizira zamagetsi zomwe zimatha kuyenda mkati mwa waya. Kenako, timayika waya pamalo ofukula maginito ndikuyiyendetsa molunjika kumunda. Ndikofunikira kuti kuyenda kwa izi ndikuthamanga kwanthawi zonse.

Zonse ziwiri za waya zizilumikizidwa ndikupanga chingwe. Tithokoze chifukwa cholumikizidwa ndipo mwanjira imeneyi tikutsimikizira kuti ntchito yonse yomwe yapangidwa yopanga magetsi mu waya izitha ngati kutentha kwa waya. Tsopano tiyerekeze kuti munthu akukoka waya ndi liwiro nthawi zonse kudzera pamagetsi. Pamene tikukoka waya tiyenera kugwiritsa ntchito mphamvu kuti maginito azitha kugwira ntchito paokha. Komabe, mutha kusintha komwe gululi likufuna. Gawo lamphamvu lomwe timagwiritsa ntchito limabwezeretsedwanso, ndikupangitsa kuti pakhale mphamvu yamagetsi yamagetsi yamagetsi yomwe imayenda kudzera pa waya. Ndikupatuka uku komwe kumakhazikitsa mphamvu yamagetsi.

Ndikukhulupirira kuti ndi chidziwitsochi mutha kuphunzira zambiri zamalamulo a Faraday ndi mawonekedwe ake.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
