Besinokubukela iimagnethi eziwela kwimibhobho yobhedu yonke imini [Ividiyo]

Iimagnethi azitsalwa kubhedu, kodwa iimagnethi ezomeleleyo ziyasebenzisana nobhedu ngendlela emangazayo. Ukuba ulahla umazibuthe we-neodymium ezantsi ngombhobho wobhedu yehla. Okukhona umazibuthe womelele kwaye utyeba ngombhobho, kokukhona ucotha ukuwa. Thatha ujongo.

Le vidiyo ithunyelwe ku-YouTube ngendlela ebuyayo ngo-2010, kodwa sayibona ngale ntsasa sibulela kwi-tweet evela kwi-astronaut / kwi-Bowie yaseKhanada engumlingisi uChris Hadfield.

Mholo ngalentsasa! Iimagnethi kumbhobho wobhedu -zenzela ividiyo engaqhelekanga engajonganga nto: http://t.co/2ObBc89l Hayi

Inkcazo yevidiyo ngu-YouTuber JamesRB1995 icacisa okwenzekayo:

Iimagnethi ze-neodymium zinamandla amakhulu kwaye nangona zingatsaleki kubhedu, zisavelisa ii-eddy currents eziphazamisa ukuwa njengoko kubonisiwe kwividiyo. Umthetho kaLenz wenza uvavanyo olukhulu kubantwana ukuba babe ngabantu abadala. Kwakhona, kuhle kumatheko xa incoko iqhubeka.

Ukuba awuqhelananga Umthetho kaLenz , IWikipedia iyichaza ngolu hlobo:

Ukunyanzelwa kombane (i-emf) ihlala inika amandla kumhlaba wamagnetic ophikisana notshintsho lwangempela kwi-magnetic flux.

Ngokusisiseko icacisa indlela imijikelezo yombane ehambelana nomthetho wesithathu kaNewton kunye nolondolozo lwamandla.

Le vidiyo yokuqala ifumana le ngongoma, kwaye sayijonga ngaphezulu kwamaxesha ambalwa, kuba iyamangalisa ngokwenene, kodwa saya kwiYouTube ukufumana okungakumbi. Sifuna iimagnethi ezinamandla, iipayipi ezijiyileyo kunye nomgangatho wevidiyo ongcono. Nantsi ividiyo yakutshanje enombhobho omkhulu wamafutha kunye nezinye iimagnethi ezinamandla ngokwenene.

Yonwabele.

Ngeli xesha kwikhonkco elinxulumene noko

• Ulwelo luyehla umdaniso kwaye lwahlule ukubetha ukubetha kwemagnethi
• Indoda ifaka iimagnethi ezindlebeni zayo ukuze izisebenzise njengeentloko ezingabonakaliyo
• Iiseli ezitsala umtsalane kumanxeba, kwaye ngoku siyayazi indlela
