Dois fios longos retilíneos, estendidos no plano do papel, se cruzam perpendicularmente sem que haja contato elétrico entre eles. Esses fios são percorridos por correntes de intensidades i1 e i2. Sendo i1 a corrente que passe pelo fio vertical com sentido norte-sul, e i2 a corrente que passa pela espira horizontal no sentido oeste-leste. Nestas condições, em quais regiões é possível ser nulo o campo magnético resultante dos dois fios?
