The steel dropped the input & output around 40 ma's equally, the aluminum did the same only to a greater extent.
I did notice that there was very little change in the rotors rpm.
I haven't tested any further than the ma drop. But it is on my list for further investigation.
Oh..the same results happen when shielding the sides of the coil.
On a side note, I made a small window coil with an led, at 40 mm from the base of the main coil it would light up, but any closer and it would start drawing current from the primary battery.
I think with a bit of tinkering one could recover a good bit of lost energy.
