'Mu-Metal' is probably the trade name of that very high permeability metal.
'Mu', among many other things refers to the magnetic dipole moment but the 'u' is usually written as 'µ'.
I've already stated that I don't believe everything is fully and correctly understood and cannot be assumed to be written in stone.
Again, if anyone has any example of disproof of any physics claim, I am game. Any such example must be supplied with enough information for a correct replication.
(Oh, my Lord! I'm sounding like others I didn't appreciate
)
Disputing claims, classic or not, are the things I enjoy most.
"however Wavewatcher you seem quite content to post this stuff with no 'child warning' what so ever, by all means quote the theory but accompany it with the caveat that it doesn't work in practice"
Stop blathering and provide an example. I already know of several. Let's see if you provide something new.

Duncan,
Just so you know... I am usually the last one to cry 'foul' upon first glance and have gone to the extra effort, on several occasions, of contacting and visiting some claiming the unusual results.
One was a water-for-fuel inventor who made extreme claims on fueling his pick-up truck with nothing but water. Since he was only an hour's drive I paid him a visit. His claims were bogus and he wound up with having to rebuild his engine. A week later he dropped off the net and the fruitcakes started posting findings of suppression and even suspected murder.
That was a few years ago. I spoke to him on the phone about a month ago. He is doing well and pursuing magnet motors under completely different identities.
Another was a very famous (at least in these circles) magnet motor inventor. His only problem was he let it go too far from just looking for advice to making ridiculous claims. He wound up adding obvious fraud evidence and claiming MIB visits just so the fruitcakes would get off his back. His claims were real but not quite as positive as he thought.
I stopped talking to him because he goes off the deep end when bothered and can't support his family.
Also,
Einstein's famous formula isn't quite correct and anyone actually using it in high level research knows that.
Lorentz isn't correct in every circumstance - also known.
Lenz isn't applicable or even correct in every instance - also known.
Aether science was never proven false by the MM experiment or later variations but it does lend credence to SR & GR. This is true for the same reason current attempts at measuring gravity waves will never provide positive results.
Did you know that simply changing the rotational axis to horizontal on a MM like experiment provides 'apparent' positive proof of the Aether theory?
Before people makes childish claims they should read a book about the subject.
All too often they instead write one and try to sell it or post the equivalent amount of bovine expulsion on web sites to see how many will take the bait.
