Physics is not everybody's cup of tea.
Many in this thread are too busy playing apologist to earnestly engage in discussions about (theoretical) physics.
Scepti has been trying, by dialectic, to get you to recognize that "fields" are not defined and that magnetism is currently a mystery to all physicists as a result. Einstein recognized that his "castle in the sky" (continuous fields / fields of any kind) may well be utter fiction towards the end of his life. We are NOT talking about wild or anti-conventional physics concepts here.
Suppose for a second, that Scepti is right (benefit of the doubt, required to earnestly evaluate and not merely "debunk")
There is something VERY small, that is a component of our air, that is responsible for magnetism. There is an abundance of it on one side (pole) of a magnet and a deficiency on the other.
Putting aside that this is a vastly more sound conception than what we currently have (magic "fields" within and comprised of nothing), from a philosophical/physics perspective - the next step is to test the notion.
As I described earlier in this thread, no experimental validation or invalidation of this hypothesis is possible until we can measure and manipulate the IV (the proposed infintessimally small thing)
That should be the focus. Physics does not take place within the mind, i.e. thought experiment is in no way experiment.
