Secondary electric field, planetary magnetism, terrestrial magnetism
It is generally believed that planetary magnetism is the result of motion of molten iron alloys in planetary body’s core region. An assumed dynamo mechanism, in core region of a planetary body, generates magnetic field by feedback loop: electric current loops in the region creates magnetic field and changing magnetic loops in turn creates electric fields. This assumption uses circular logic. As linear speed of a spinning planetary body is much greater than (tangential) linear motion of its constituent matter particles due to planetary body’s spin speed, every matter particle in spinning planetary body always moves in same direction in space. Spin motion of a planetary body is an illusion and it is valid only for considerations with respect to static reference of planetary body’s spin axis. As real motion of all matter particles of a spinning planetary body (with respect to absolute reference) is always in same linear direction, swirling motion of a planetary body’s interior is a myth. To consider this imaginary swirling motion of planetary body’s magma, as the cause of planetary magnetism is not tenable. Even for dynamo effect to occur, a primary source of magnetism is required, which is absent in this case. Cause and nature of planetary magnetism, described in this article, is based on a radically different concept, presented in ‘MATTER (Re-examined)’. For details, kindly refer to same .
