Suppose that the magnetic field of the Earth were due to a single current moving in a circle of radius 2910 km through the Earth's molten core. The strength of the Earth's magnetic field on the surface near a magnetic pole is about 6.0 x 10-5 T. How large a current (in the equatorial plane) would be required to produce such a field?
