Earth's Charge and the Charges of the Van Allen Belts

Authors: Jacob Biemond

In this paper three separate charges are distinguished for the Earth and its magnetosphere. First, it is assumed, that the Earth and its nearest atmosphere bear a net negative charge QE. Secondly, a positive charge Qi and a negative charge Qo are proposed for the inner and outer Van Allen belt, respectively. Thirdly, a belt with net zero charge (electron slot) will be assumed to be present between both charged belts. According to the three tori model, recently developed for pulsars and black holes, equilibrium may exist between the charges QE, Qi and Qo. Three expressions for the Coulomb electric field at different distances from Earth's centre are derived from the same model. Using available data, values for the three charges are deduced for the solar minimum and maximum, respectively. An averaged charge QE of about −1 C is extracted for the Earth. Some other features of the model are discussed, among them the flow of charge during the change from solar minimum to maximum. Furthermore, it is shown that the magnitude of Earth's magnetic field cannot be explained by the motion of the charges QE, Qi and Qo. In order to obtain a better explanation, the so-called Wilson-Blackett law is discussed. In addition, a large toroidal electric current in the Earth is proposed
