Experimental method of permanent magnet rotation

Abstract Why does the earth rotate? In the 17th century, an accurate description of the earth’s rotation was provided via Newtonian mechanics1. However, the driving force was not given a mechanistic treatment, was merely ascribed to a “push” by God. At present, All kinds of theories about the rotation of the planet are still hypotheses2,3. In this study, It provides experimental evidence for researching the relationship between planet (Earth) rotation and magnetic fields4. The proposed experimental devices and research methods are based on the characteristics of the kinematic relations between the sun and planet. A permanent magnet representing the sun is installed on the shaft of a DC motor, spherical magnet representing the planet is designed at the center of hollow sphere and can float on water, ensure free rotation. Based on the above device5, the method of permanent magnet rotation in magnetic field and the experimental procedure of rotation reason are introduced.
