n the figure, two concentric circular loops of wire carrying current in the same direction lie in the same lane. Loop 1 has radius 1.50 cm and carries 4.40 mA. Loop 2 has radius 2.30 cm and carries 6.20 mA. Loop is to be rotated about a diameter while the net magnetic field B set up by the two loops at their common enter is measured. Through what angle must loop 2 be rotated so that the magnitude of the net field is 108 T?
