Alternative sources for geomagnetism

摘要

The paper proposes and argues in favour of an alternative model to account for the dipole geomagnetic field in which a hitherto unrecognized piezo-magnetic effect is the actual cause. This model offers a plausible explanation for the observed field reversals, the westward drift, and the secularly decreasing field strength. It is consistent with recent satellite data, and capable of generalization to planets other than Earth. It also accounts for the fact that the dipole axis is displaced from the geographic axis, and that the center of the dipole is displaced from the geographic center.
