👉 Tractism is a scientific theory that suggests that the Earth's magnetic field, which has been observed to vary over time and space, can be caused by the movement of charged particles. This theory posits that the magnetic field is generated by the motion of particles such as protons or electrons in the Earth's outer core, causing them to move through a region known as a "tract." The theory suggests that this movement creates an electric current, which then causes the Earth's surface to experience
