It acts identically for wherever you are on a flat earth.
If it's a giant magnet inside earth, then the earth must be round, or else the south magnetic field wouldn't act as a mathematical pole.
Please explain why. The field lines would line up perfectly with common everyday observation.
Because a mathematical pole is a point. And the circumference of a circle, is not. That is the explanation why.
Irrelevant. It will function as a pole as the field lines are close enough to identical. Also: mathematical poles are points. Points don't exist, nor do mathematical poles. Why are we talking about fictions?
Of course this issue melts away in my model, however you asked for the standard explanation. This is it. The north pole is below the North pole and at such a distance away and magnitude that the field lines allow magnetic phenomena to function in a similar manner as expected by RE models.
No it does not go away it get worse. The magnetic NP is located in a different place than the Polaris NP and it keeps moving to different places, even managing at times to completely flip the polarity.
Why would magnetism have any issues in this model: http://www.theflatearthsociety.org/tiki/tiki-index.php?page=Davis+Model#A_Flat_Earth_Theory
Because the Man NP and Polaris NP are not that close to gather. Here where I live there is a 2 degree West difference. In Los Angeles there is an 18 East degree difference. That makes a 20 degree total difference.
That is a hell of a change in just over 1600 miles in the location differences between the P NP and M NP. There is a common term for not accounting for the different, LOST
I'm sorry, but I don't think you understand the model you are trying to argue against. Magnetism, like almost every other phenomena, works exactly the same in this model. To prove it wrong for my theory would essentially be proving round earth theory incorrect as well.
The maps of FET with magnetic lines posted here show the M NP and P NP as the same location. They are NOT.
Maybe your FE map shows the difference? But that beings up more problem. There are no set rules for FET, they are as varied as there are people that believe in it.
Your map may show the difference in poles
Other maps don't show any difference in the poles
Round planets but only Earth is flat
All planets are flat
All plants are the same size
Earth is bigger than all the other planets
E=MC
2 works
E=MC
2 is "Voodoo" and nuclear bombs are fantasy
UA doesn't mean the Earth is traveling at 99.9999999999999 of C
UA doesn't apply to E=MC2
UA does apply to E=MC2 but time dilation doesn't.
Rockets cannot work in a vacuum because a vacuum has nothing in it, but a Gulfstream traveling at 508 mph can reflect a light off the vacuum to make people think the ISS is really there and traveling more that 30 times as fast as the plane.
Mass is not related to gravity

Math proves Newton' laws
Math won't work when dealing with a vacuum.
Trigonometry work on Earth but the universe is too big for its use.
The universe is very very small.
I could write a 1000 pages of contradictions about FET just from these forums.
Debating FET is like attempting to tie down tornado with a length of thread. The rules change to fit the belief of the person being asked questions.
HOWEVER this place is great source for story ideas.
