Magnetism as Energy in the Tree Trunk - Finite-Core Dynamo Hypothesis

In my previous works I proposed that extreme gravitational collapse does not create a singularity but a finite high-density core. In this note I extend my own hypothesis: this finite core can have two parts - inner dense part and outer conductive shell with electric currents. Part of the total energy goes to magnetic field. This can explain magnetar-scale fields of 10^15 G as a natural consequence of the finite-core structure, requiring only 0.00003 percent of the gravitational energy. Stability is given by B_n = 0. My tree model: +F_n = growth, -F_n = collapse, B_n = 0 = balance, S_n = 2F_n = E_core + E_magnetic.
