Abstract

The present work is devoted to the study of the planet's equatorial magnetic fields. The formula is obtained that expresses a direct dependence of the planet's magnetic field value at the equator from the values of the planet's orbital velocity, equatorial speed, mass, obliquity to orbit, dipole tilt to rotational axis, orbit inclination, surface area and semimajor axis. Moreover, there is a constant, linking all of the above. We call it the second magnetic constant. The importance of the obtained constant is so important that it is characteristic not only of the planets belonging to the Solar system, but also of other planetary systems with a magnetic field.
