STUDY OF PLANETARY MAGNETIC FIELDS

Magnetic fields are an important phenomenon in the solar system and beyond. Their causes are complex and have a variety of effects on their surroundings; they have become a critical tool for the exploration of solar system bodies. Magnetic fields play a very important role in the Sun. From sunspots to coronal heating, from solar ares to coronal mass ejections all these apparently diverse phenomena have magnetic fields as their ultimate cause. The study of the terrestrial dynamo is a difficult problem made more so by the inability to construct planetary-scale dynamos for laboratory study. However, understanding the nature of the matter comprising the Solar System is crucial for understanding the mechanism that generates Earth's geomagnetic field and the magnetic fields of other planets and satellites planetary dynamo models. In this study, in this study, classifications of planets are introduced. Development of planetary magnetism model is discussed. General concepts of the magnetic dynamo theory are introduced. Properties of planetary magnetic fields are presented and Earth crustal magnetic field is briefly discussed.
