Are there any running magnet motors?

Yes, I see the point but I'm not satisfied by this reading. Something is still missing.
I miss the scientific pinpoint explanation of why the magnets would get demagnetized. Especially resistent neo magnets.
Let's us see if my FBDISSM will work, like supposedly Sprains EMILIE, then we will know by first hand if the magnets will get demagnetized.

That?s exactly the point: resistant neo magnets will not get demagnetized.
Unless, forcefully opposed to equally strong and resistant neo magnets?

Remember that an ideal magnet should entirely expel magnetic fields (i.e. superconductors). However, this is not the case for real magnets. Any external H will push Br up or down along the hysteresis curve. Normally those variations are small and pretty much reversible as long as external H is successively attractive and repulsive and not too intense. But when H is strong and when is constantly opposing Br, permanent effects are noticed.
I can not confirm the above for neo because neos are imho too valuable to degrade them in such experiments. But I can confirm that ceramic (speaker) magnets get noticeably demagnetized if placed N-N or S-S at close proximity for some time (usually hours).

G'day all,

I have been very quiet until now.

When I earlier pointed out that the amount of energy required to create a magnet was conveniently ignored by most researchers, which seem to see in a permanent magnet a thing that just happens to exist on its own rather than something that had been created with a considerable amount of energy.

The question is where did that energy go?

I was abused for making such a statement. I did not make that statement lightly but as a result of considerable experimentation and contemplation.

It therefore surprises me that no-one to date has actually asked me why I would be making such a statement and what my thoughts on the matter are in detail. Instead I get abuse from those who want us to believe they have a scientific approach to things and accuse me of being unscientific.

If abuse instead of reasoned argument is scientific then I am indeed no scientist.

I can update you that I've had N50M neo magnets in totaly close repel mode for 5 month by now and they show no sign of demagnetization at all.

I have also built a motorized repel unit the see if there is any risk of demagnetization at motion in close repel. See point 2.

Hong Thanks it is great to see someone doing and not talking all on faith!!!
