In the figure, two concentric circular loops of wire carrying current in the same direction lie in the same plane. Loop 1 has radius 1.70cm and carries 4.40 mA. Loop 2 has radius 2.40 cm and carries 5.70 mA. Loop 2 is to be rotated about a diameter while the netmagnetic field B set up by the two loops at their common center is measured. Through what angle must loop 2 be rotated so thatthe magnitude of the net field is 91.0 nT?NumberiUnits
