On Planetary Electromagnetism and Gravity

Abstract

Study of the interiors of the various terrestrial planets, as presented in the paper, leads to the possibility of planetary gravity being linked to the electromagnetism generated in the planetary interiors. Findings of the study undertaken suggest that Earth’s gravitational attraction may be attributed to magnetic coupling experi-enced between Earth's electromagnetism and all the earthly objects - electrically charged or uncharged. More precisely, terrestrial gravity is deemed to be outcome of the bound state of the planetary electromagnetism.
