A alternativa correta é a letra "a) I e II estão corretas". A primeira afirmativa está correta, pois o magnetismo é a propriedade de atração e repulsão de certos metais e ímãs, que possuem um polo positivo e um polo negativo. A segunda afirmativa também está correta, pois a propriedade magnética de dipolo informa que polos iguais se repelem e polos opostos se atraem.
