Natural association of matter particles is to form an electro-magnetically neutral body. All planetary bodies are initially electromagnetically neutral bodies. It is the acquired parameters of these bodies, which produce their magnetism. Apparent spin motion of a planetary body does not cause interior matter to swirl around its axis of spin. To consider this imaginary swirling motion of a planetary body's magma, as the cause of planetary magnetism is not tenable.
Cause and nature of planetary magnetism is described here on the basis of a radically different concept, put forward in "Hypothesis on MATTER". Planetary magnetic field is produced by directional alignment of free floating atoms in relatively calm fluids on or near the surface of a spinning planet and it is sustained by induced magnetism of the body's ferrous core. Alignment of free floating atoms and hence the strength of planetary magnetism depends on absolute linear speed of the planetary body and quantity of fluid matter on it. Planetary magnetism is created by linear speed of the planet and sustained by apparent spin motion of a planet that has ferrous matter as its core. Magnets formed about either hemisphere of a planet (about its equator) are independent of each other. Natural upheavals or gradual re-distribution of ocean water on earth, affect the strength and direction of terrestrial magnetism.
