The Maintenance Problem of the Earth's Magnetic Field

Matti Pitkänen


The understanding of the Earth's magnetic field, call it BE for shortly, is still far from complete. One problem is to understand why it can exist stable at all. The idea is that the convective heat flow from the core of Earth provides the needed energy to compensate for the dissipation. Also the understanding of the orientation reversals of BE is poor although numerical simulations can reproduce them. The new view about electromagnetic fields provided by TGD suggests a solution to the maintenance problem. The magnetic fields assignable to monopole flux tubes require no currents as sources so that dissipation does not destroy them. BE would contain the monopole flux part and the purely Maxwellian part.
