Uma espira circular condutora de raio 30 cm é percorrida por uma corrente elétrica de intensidade 2,0 A, no sentido anti-horário. Outra espira de raio 15 cm é concêntrica à anterior e está situada no mesmo plano da primeira. Determine a intensidade e o sentido da corrente elétrica que, percorrendo a segunda espira, anula o vetor indução magnética resultante no centro do sistema. (Considere: µ0 = 4π.10-7 T. m/A e π = 3,0).
