iindaba

Isikhokelo: Kutheni le nto iikhoyili zokutshaja ezingenazingcingo kufuneka zongeze izikhewu zemagnethi, ushwankathela le miba mithathu ilandelayo:

1. Ukungena kwemagneti

Njengoko sonke sisazi, umgaqo womgangatho wokutshaja ngaphandle kwamacingo we-QI kwizithintelo zemagnethi kukufakelwa kwe-electromagnetic. Xa i-coil ephambili (i-wireless charging transmitter) isebenza, iya kuvelisa i-interactive magnetic field (i-direction of power itshintsha rhoqo). Ukuze wenze amandla ombane akhutshwe yi-coil ephambili isenzo kwi-coil yesibini (ummkeli wokutshaja ongenazintambo) kangangoko kunokwenzeka, kuyimfuneko ukuba I-magnetism yekhoyili ikhokelwa.

2. Ibhloko yemagnethi

Iphepha lamagnetic alifanele likwazi ukuqhuba ngokufanelekileyo i-magnetism, kodwa liphinde lidlale indima ekuthinteleni i-magnetism. Kutheni uvimba imagnethi? Siyazi ukuba xa intsimi yamagnetic eguqukayo idibana nomqhubi onjengentsimbi, ukuba isinyithi singucingo oluvaliweyo, luya kuvelisa okwangoku, ukuba isinyithi silucingo oluvaliweyo, ngokukodwa isiqwenga sesinyithi, umphumo wangoku we-eddy uya kwenzeka. .

3. Ukutshatyalaliswa kobushushu

I-magnetic field isebenza kwi-coil ye-inductor ukuvelisa i-high-frequency current. Ngethuba le nkqubo, i-coil ngokwayo iya kuvelisa ubushushu. Ukuba obu bushushu abuchithwanga ngokufanelekileyo, buya kuqokelelana. Ngamanye amaxesha siziva sishushu kakhulu ngexesha lokutshaja ngaphandle kwamacingo. Ngokuqhelekileyo, kubangelwa ukufudumeza kwe-coil inductance okanye ukufudumeza kwebhodi yesiphaluka.
