Verhoogen proposed that this entity's growth releases heat to a surrounding body that creates Earth's magnetic field via dynamo effects.
Marvin Herndon proposes that this entity contains a large amount of uranium sulfide acting as a breeder reactor. Verhoogen proposed that this entity's growth releases heat to a surrounding body that creates Earth's magnetic field via dynamo effects. Gubbins and Loper attribute that phenomenon to gravitational convection in that surrounding layer. This entity has been estimated to rotate a degree per year faster or slower than the earth at large. Discovered in 1936 by Inge Lehmann, for 10 points, name this solid nickel-iron ball with temperature estimated to be around 5700K, younger than the earth as it, as J. A. Jacobs predicted, is freezing out of the liquid layer outside it.
