O magneto \u00e9 um dispositivo de igni\u00e7\u00e3o autossuficiente utilizado em motores de combust\u00e3o interna, como os de aeronaves, para gerar a centelha que inflama a mistura ar-combust\u00edvel nos cilindros. Seu princ\u00edpio baseia-se na indu\u00e7\u00e3o eletromagn\u00e9tica e no controle do fluxo magn\u00e9tico.<\/p>\n\n\n\n

  1. Enrolamento e N\u00facleo de Ferro:<\/strong> O magneto possui um n\u00facleo de ferro cercado por dois enrolamentos: prim\u00e1rio e secund\u00e1rio. Estes enrolamentos s\u00e3o bobinas de fio condutor que armazenam energia na forma de campos magn\u00e9ticos.<\/li>\n\n\n\n
  2. \u00cdm\u00e3 Permanente:<\/strong> Um \u00edm\u00e3 permanente gira entre os polos do n\u00facleo de ferro, gerando um fluxo magn\u00e9tico vari\u00e1vel.<\/li>\n\n\n\n
  3. Indu\u00e7\u00e3o no Enrolamento Prim\u00e1rio:<\/strong> Esse movimento c\u00edclico do \u00edm\u00e3 induz uma corrente alternada no enrolamento prim\u00e1rio. Este processo \u00e9 regulado por um componente chamado platinado<\/strong>, que funciona como uma chave mec\u00e2nica.<\/li>\n\n\n\n
  4. A\u00e7\u00e3o do Platinado:<\/strong> Em um ponto espec\u00edfico do ciclo, o platinado se abre, interrompendo a corrente no enrolamento prim\u00e1rio. Essa interrup\u00e7\u00e3o faz com que o fluxo magn\u00e9tico varie abruptamente.<\/li>\n\n\n\n
  5. Indu\u00e7\u00e3o no Enrolamento Secund\u00e1rio:<\/strong> A r\u00e1pida mudan\u00e7a no fluxo magn\u00e9tico gera uma alta tens\u00e3o no enrolamento secund\u00e1rio. Esta tens\u00e3o elevada \u00e9 necess\u00e1ria para criar uma fa\u00edsca que atravesse o gap da vela de igni\u00e7\u00e3o.<\/li>\n\n\n\n
  6. Disparo da Vela de Igni\u00e7\u00e3o:<\/strong> A alta tens\u00e3o do secund\u00e1rio \u00e9 conduzida para a vela de igni\u00e7\u00e3o, gerando a fa\u00edsca que inflama a mistura no cilindro.<\/li>\n<\/ol>\n\n\n\n
