The earth's magnetic field, with a magnetic dipole moment of 8.0×1022am2, is generated by currents within the molten iron of the earth's outer core. suppose we model the core current as a 3000-km-diameter current loop made from a 1000-km-diameter "wire." the loop diameter is measured from the centers of this very fat wire.
a. what is the current in the current loop?
b. what is the current density j in the current loop?
c. to decide whether this is a large or a small current density, compare it to the current density of a 3.0 a current in a 2.0-mm-diameter wire.
