Yes, ring magnets exist, but how can the poles reverse on such a magnet shape and what would be the resulting magnetic field if the poles drifted slowly as they are now? At what point would the poles cancel each other out? Also, ring magnets don't just have two poles, fyi.
There is no “South Pole” in the flat model.
Magnetic monopoles don't exist. See Gauss' Law for the reason. If they did exist, we could have stable magnetic levitation and Back to the Future hoverboards would be real.
There is no singular “South Pole” in the flat earth model. There is also no dipole spherical magnet in nature or even manufactured. There is no reason to believe you live on one.
I tend to avoid these “gotcha” question threads because they’re dishonest. You have to have a critical thinking mindset to ever understand flat earth. Meaning that when you ask “why does the core shift polarity” or whatever, any actual flat earther immediately realizes that you don’t have any way of knowing that the earth has a molten iron core. It is literally impossible for you to know that. So you’re asking questions from basically a false premise.
