MockEddy currents:Try this: drop a neo magnet, ideally a spherical one, down an aluminium tube. It looks as if you have discovered anti-gravity, it takes so long to hit the other end, as it floats ever so slowly, down.
The same with copper, brass, and of course, steel, where it just grabs and doesn't fall, a bit.Howard Johnson made his fateful hero motor from aluminium, that at show time was a dud.Eddy currents!Cheers Warren

Hi Doug,
What are the pros and cons of using aluminum plate to mount either the
magnets or coils on your Muller-Kone gen heads?
I imagine something really expensive and hard to machine like austenitic
stainless or titanium would be best if using metal, or composite high
temp carbon fiber with silicon nitride bearings but wanted to check if
aluminum's paramagnetic property degrades performance.
I have seen some rotors of aluminum but seem to recall your opinion it
was not optimal.
