A fannin fasaha, wasu ƙirƙira sun taka muhimmiyar rawa wajen canza duniya kamar yadda muka san ta. Ɗaya daga cikin irin wannan ƙirƙira ita ce magnetron, wani muhimmin sashi a cikin tanda na microwave. Yadda magnetron ke aiki ya cancanci a bincika domin yana bayyana hanyoyin da ke bayan wannan na'urar juyin juya hali.
Idan ana maganar magnetrons, tushen ya ta'allaka ne akan hulɗar da ke tsakanin filayen lantarki da maganadisu. Wannan hulɗar da ke cikin bututun injin yana haifar da samar da raƙuman lantarki masu yawan mitoci, galibi a cikin nau'in microwaves. Waɗannan tanda na microwave suna ba wa microwave damar yin aikin girkinsa cikin sauƙi.
Magnetron ya ƙunshi muhimman abubuwa da dama, kowannensu yana da manufa ta musamman a cikin tsarin aiki gaba ɗaya. A tsakiyarsa akwai cathode, wani filament wanda ke fitar da electrons lokacin da aka dumama shi. Daga nan sai waɗannan electrons su jawo hankalin anode, silinda na ƙarfe a tsakiyar magnetron. Yayin da electrons ke kusantar anode, suna haɗuwa da wani filin maganadisu na waje wanda maganadisu ke kewaye da anode ɗin ke samarwa.
Wannan filin maganadisu ne ke taka muhimmiyar rawa a yadda magnetron ke aiki. Saboda ƙarfin Lorentz, electron mai motsi yana fuskantar ƙarfi a tsaye zuwa ga alkiblar motsinsa da kuma layukan filin maganadisu. Wannan ƙarfin yana motsa electrons a kan hanya mai lanƙwasa, yana juyawa a kusa da anode.
To, a nan ne sihirin ya faru da gaske. Siffar silinda ta anode tana da rami ko resonator wanda ke aiki a matsayin ɗakin da babu komai. Yayin da electrons ke motsawa a kusa da anode, suna wucewa ta cikin waɗannan resonators. A cikin waɗannan ramuka ne electrons ke fitar da makamashi a cikin nau'in raƙuman lantarki.
Haɗakar filin maganaɗisu da kuma resonator yana bawa electrons damar fitar da makamashi ta hanyar da aka daidaita, wanda hakan ke haifar da microwaves masu yawan mitoci. Sannan ana tura waɗannan microwaves ta hanyar eriya mai fitarwa zuwa cikin ramin girki na tanda na microwave.
Yadda magnetron ke aiki ya kawo sauyi a yadda muke girki da dumama abinci. Samar da ingantaccen tsari da isar da microwaves yana ba da damar dafa abinci cikin sauri, har ma da sauri, wani abin da ba a taɓa tunaninsa ba a da. A yau, tanda na microwave kayan aiki ne na yau da kullun na gida godiya ga kyakkyawan ƙirar magnetron.
A cikin labaran da suka gabata, ci gaban fasahar magnetron ya haifar da farin ciki a cikin al'ummar kimiyya. Masu bincike suna binciken hanyoyin da za a ƙara inganci da samar da wutar lantarki na magnetrons. Wannan zai iya haɓaka ƙarfin tanda na microwave da kuma aikace-aikace a wasu fannoni kamar radar da sadarwa.
Gabaɗaya, abin mamaki ne yadda magnetron ke aiki, yana nuna ƙarfin binciken kimiyya mai ban mamaki. Ta hanyar amfani da hulɗar da ke tsakanin filayen lantarki da maganadisu, magnetrons suna buɗe hanya don dafa abinci mai sauƙi da inganci.
