In terms of 'edification', I don't really see this website as a means of improving myself or my intellect of anything.
Fair enough. Perhaps you would have had less reaction/resistance had I used the word "clarification" instead of edification. In any case, the reasons to engage in a site like this is precisely that, edification, in my view (about many things, and generally minimally to do with the true shape of the world)
My questions are simply a tool to try and find out how far those who present their 'alternative' ideas about the Earth have actually researched them. There is a huge difference between simply making a claim (that the Sun and Moon are holographic projections for example) and being able to produce real and verifiable evidence that those claims are actually correct.
Agreed. However, getting clarification on those claims by asking your questions will (ideally) lead to edification (even if that edifying is that Scepti cannot justify/support their claims adequately in your view)
If you can find any posts by Sceptimatic where he actually and explicitly admits he is wrong about anything he claims then please point me to them.
I can't speak to that, and I agree that the inability to be humble (required for objectivity and to recognize and address one's mistakes) is a major shortcoming. I'm sure that Scepti has as much experience being wrong as the rest of us, and I hope that they would not delude themselves to deny that (to themselves or anyone else).
His consistent 'get out' clause is that he only presents his ideas as what he believes in and doesn't make them out to be factual and real.
That is a fine out, however of course it is not science. Through mere discussion and imagination all things are possible/conceivable. When you test those possibilities/conceptions against reality by experiment is when it begins to be science, and not before.
So if someone asked you for a clear and precise definition of magnetism and what causes it, what would you say to them?
I would say that honestly we don't know, but there are some conceptions that are popular and useful. In one of my, admittedly speculative, conceptions of it the magnetic "force" comes from infinitesimal sized magnetic monopoles inside and surrounding the magnet. Much like einstein towards the end of his life, I have come to the conclusion that "fields" are not a thing in reality (only equation). Everything is discrete, as the quantumnists have found/demonstrated.
The pressure comes directly from each magnet to the walls.
How? What creates the pressure?
This is a question for Scepti. My stab at their potential response would be that the pressure is created by preferential absorption or expulsion (perhaps by the shape or structure of the magnetic material) of very fine / permeable things in and/or related to our air.
If I place a piece of brass or copper on the outside of the plastic box then move it around near the magnet inside the box it does not move. Why not?
Again, a question for Scepti. I presume it will once again come down to the material itself being perhaps already saturated with, or maybe resistant to, the small things responsible for the magnetic effect and pressure thereof.
Are you certain the magnet will not move? We can certainly cause the magnets motion to be altered by simple proximity to copper (lenz's law) - so I would not be surprised to find a minor motion in the reverse (in fact, I would be surprised if it was completely absent)
It forms a pressure circuit.
Surely what you call a 'pressure circuit' is basically what I would call a magnetic field. Yes?
Again for Scepti.
So I take it we are in agreement then that your claim (that Scepti partially confirmed my interpretation of their statements merely because I agree with them) was in error?
