A resposta correta é a alternativa (c) Todas as afirmações estão corretas. Esses experimentos nos dizem que o magnetismo é diferente da eletricidade, que o magnetismo é uma força de ação à distância, que os ímãs têm dois polos, chamados norte e sul, que os polos de um ímã podem ser identificados usando outro ímã e que os materiais que são atraídos por um ímã são chamados de materiais magnéticos.
