COMO UM IMÃ FUNCIONA? IMÃS PARECEM MINHOCAS! Quando você quebra um ímã — digamos, um imã em barra com um polo norte em uma ponta e um polo sul na outra — algo curioso acontece: você não obtém um pedaço só com N e outro só com S. Em vez disso, surgem dois ímãs menores, cada um com seu próprio N e S. #ciência #física #curiosidades #ima #educação
