In the figure, two concentric circular loops of wire carrying current in the same direction lie in the same plane. Loop 1 has radius 1.30 cm and carries 4.40 mA. Loop 2 has radius 2.70 cm and carries 6.40 mA. Loop 2 is to be rotated about a diameter while the net magnetic field B set up by the two loops at their common center is measured. Through what angle must loop 2 be rotated so that the magnitude of the net field is 100 nT? & Number i Units
