Wondering about Mu metal

[beedees]

Hi Dan,

Could I be curious to learn about your setup? Because so far I have not managed to gain enough output from any setup I tried to run itself.     
If your setup runs itself, then you have made a huge step forward from your first post here in this thread where you mentioned 50-60%.
I think if you try to mis-direct flux, the higher permeability material you use the better BUT saturation is the tradeoff here. From this point of view the normal mains transformer laminations are good (and relatively still cheap), no real need for exotic mu-metal or permalloy or even metglas, especially,when you quickly wish to test an idea.

I tried running magnet wheels side by side instead of inside of each other. Not too impressive. Doing it like this gives you distance between magnets, and a limited time-distance of interface.   Dan
