Here is what the flat earthers have to say:LDScop wrote:Explain how earth's magnetic field works on a flat earth. Also explain how stars rotate in opposite directions depending on if you're observing from the north or south hemisphere.
While it's true that unipolar magnets can't exist, this isn't a problem for the Flat Earth. This is because ring magnets, which are shaped like (you guessed it!) a flat disk, are capable of having radial magnetization. In a radial magnet, one magnetic pole is at the center and other other is at all points on the edge of the magnet. A magnet like this can be found in loudspeakers, and perfectly replicates what is found on the Earth.
