About “the currents responsible for the Earths magnetic field lose energy to electric resistance”, did you mean electric current? And how does the electric current being generated in the core?
Reply Yes, I meant electric currents. As to how they are generated–it’s a long story. This file is part of a collection of web pages “The Great Magnet, the Earth” giving a historical review of the Earth’s magnetism, Its home page is http://www.phy6.org/earthmag/demagint.htm and the “dynamo mechanism” generating such currents is discussed in section 12 and beyond, and also in the technical review “A Millennium of Geomagnetism” included in the collection. Please, find your answer there!
