The misconception that the Earth is flat emerged in ancient times. In early Egyptian and Mesopotamian mythology, the world was portrayed as a disk floating in the ocean. Several pre-Socratic philosophers, including Thales, Leucippus and Democritus, believed the world was flat. Ironically, despite the scientific fact of Earth's sphericity, flat Earth conspiracy theories still persist nowadays and are spreading around the globe. Mike Huges, who was a well-known flat Earther, even attempted to prove the Earth is flat by launching his homemade rocket, but ended up dying tragically in a mission. In addition, many flat Earthers believe gravity is a hoax and does not exist, which disagrees with classical physics. In this article, I am going to demonstrate a flat Earth model that incorporates the effect of gravity well by replacing gravity with magnetic force, and subsequently discuss about the non-uniformity of magnetic field described by the model.
