You travel to the north magnetic pole of the Earth, where the magnetic field points vertically downward. There, you draw a circle on the ground. Applying Ampere's law to this circle, show that zero current passes through its area. | Numerade

Earth dipole ** At the north magnetic pole the earth's magnetic field is vertical and has a strength of 0.62 gauss. The earth's field at the surface and further out is approximately that of a central dipole. (a) What is the magnitude of the dipole moment in joules/tesla? (b) Imagine that the source of the field is a current ring on the "equator" of the earth's metallic core, which has a radius of 3000 km, about half the earth's radius. How large would the current have to be? | Numerade

SOLVED:A simplified model of Earth's magnetic field has it originating in a single current loop at the outer edge of the planet's liquid core (radius 3000 km ). What current would give the 62-μT field measured at the north magnetic pole?
