Question

The magnitude of the magnetic dipole moment of Earth is $8.0 \times 10^{22} \mathrm{J} / \mathrm{T}$ . (a) If the origin of this magne- tism were a magnetized iron sphere at the center of Earth, what would be its radius? (b) What fraction of the volume of Earth would such a sphere occupy? Assume complete alignment of the dipoles. The density of Earth's inner core is 14 $\mathrm{g} / \mathrm{cm}^{3} .$ The magnetic dipole moment of an iron atom is $2.1 \times 10^{-23} \mathrm{J} / \mathr The magnitude of the magnetic dipole moment of Earth is$8.0 \times 10^{22} \mathrm{J} / \mathrm{T}. (a) If the origin of this magne- tism were a magnetized iron sphere at the center of Earth, what would be its radius? (b) What fraction of the volume of Earth would such a sphere occupy? Assume complete alignment of the dipoles. The density of Earth's inner core is 14\mathrm{g} / \mathrm{cm}^{3} .$The magnetic dipole moment of an iron atom is$2.1 \times 10^{-23} \mathrm{J} / \mathrm{T}$. (Note: Earth's inner core is in fact thought to be in both liquid and solid forms and partly iron, but a permanent magnet as the source of Earth's magnetism has been ruled out by several considerations. For one the temperature is certainly above the Curie point.)
