The magnetic dipole moment of Earth has magnitude 8.00 x 1022 J/T. Assume that this is produced by charges flowing in Earth's molten outer core. If the current is measured to be 2.08 x 109 A, what is the radius of the charges' circular path?
Helmholtz coils are frequently used in experiments because they create a uniform magnetic field about their central axis. For example, they are traditionally used in the experiment for the measurement of the charge-to-mass ratio of the electron. Helmholtz coils are two coils separated by a distance equal to their radius that carry equal currents in the same direction." Suppose the radius of the coils is R 18.00 cm and each coil carries a current of /== 11.50 A and has N 340.0 turns. The coils are in the yz plane where one coil's center is at x = 0 the other coil's center is at x = R. -X=R 00
