ka'idar aiki na magnetron

A cikin fasaha, wasu ƙirƙira sun taka muhimmiyar rawa wajen canza duniya kamar yadda muka sani. Ɗayan irin wannan ƙirƙira shine magnetron, wani muhimmin sashi a cikin tanda na lantarki. Yadda magnetron ke aiki ya cancanci bincika yayin da yake bayyana hanyoyin da ke bayan wannan na'urar juyin juya hali.

Idan ya zo ga magnetrons, abubuwan da suka fi dacewa sun kasance a kusa da hulɗar tsakanin filayen lantarki da Magnetic. Wannan hulɗar da ke cikin bututun injin yana haifar da haɓakar raƙuman ruwa mai ƙarfi na lantarki, galibi a cikin nau'ikan microwaves. Waɗannan tanda na microwave suna ba da damar microwave don yin aikin dafa abinci cikin sauƙi.

Magnetron yana ƙunshe da abubuwa masu mahimmanci da yawa, kowannensu yana ba da manufa ta musamman a tsarin aikin gabaɗayan. A tsakiyarsa akwai cathode, filament wanda ke fitar da electrons lokacin zafi. Wadannan electrons suna jan hankalin zuwa ga anode, silinda karfe a tsakiyar magnetron. Yayin da electrons suka kusanci anode, suna cin karo da filin maganadisu na waje wanda magnets ke kewaye da anode.

Wannan filin maganadisu ne ke taka muhimmiyar rawa a yadda magnetron ke aiki. Saboda ƙarfin Lorentz, lantarki mai motsi yana samun ƙarfi daidai gwargwado ga alkiblarsa da kuma layin filin maganadisu. Wannan ƙarfin yana motsa electrons tare da hanya mai lanƙwasa, suna juyawa a kusa da anode.

Yanzu, a nan ne ainihin sihiri ya faru. Siffar siliki ta anode tana da rami ko resonator wanda ke aiki a matsayin ɗaki mara kyau. Yayin da electrons ke motsawa a kusa da anode, suna wucewa ta cikin waɗannan resonators. A cikin wadannan kogo ne electrons ke fitar da makamashi a cikin nau'in igiyoyin lantarki.

Haɗin filin maganadisu da resonator yana ba wa electrons damar sakin makamashi ta hanyar aiki tare, ƙirƙirar microwaves masu girma. Ana sarrafa waɗannan microwaves ta hanyar eriyar fitarwa zuwa cikin kogon dafa abinci na tanda microwave.

Yadda magnetron ke aiki ya canza yadda muke dafa abinci da zafi. Ingantacciyar ƙira da isar da injin microwaves yana ba da damar sauri, har ma da dafa abinci, abin da ba a iya misaltawa a baya. A yau, tanda microwave kayan aikin gida ne na gama gari godiya ga kyakkyawan ƙirar magnetron.

A cikin labarai na baya-bayan nan, ci gaban fasahar magnetron ya haifar da farin ciki a cikin al'ummar kimiyya. Masu bincike suna binciko hanyoyin da za a ƙara haɓaka aiki da ƙarfin ƙarfin magnetrons. Wannan zai iya haɓaka ƙarfin tanda na microwave da kuma aikace-aikace a wasu wurare kamar radar da sadarwa.

Gabaɗaya, abin mamaki ne yadda magnetron ke aiki, yana nuna ƙarfin binciken kimiyya mai ban mamaki. Ta hanyar yin amfani da hulɗar tsakanin filayen lantarki da na maganadisu, magnetrons suna share hanya don dacewa da ingantaccen dafa abinci. Tare da ci gaba da ci gaban fasaha, za mu iya hango cewa za a sami mafi kyawun aikace-aikacen fasahar magnetron nan gaba.
