Assume that the magnetic field of the earth is due to charged particles circulating in the molten core of the earth. If the magnetic dipole moment of the earth has magnitude 8.00 x 1023 J/T and we assume that the radius of the circular path taken by the charged particles is 3.50 x 106 m, what is the current produced by those charges? (Give your answer in the form "a.bc x 10^(y) A".)
