Howard Johnson Replication Tube Claim

I just noticed a comment by Dr. Schmitt:
This seems to make sense.

It's because the copper alloy that you are using is probably not is not pure electrolytic copper but a copper/ hard nickle ferromagnetic alloy. When you slide one pole along the surface of the copper bar it orients the the regions in the bar corresponding to the pole of the magnet. After the magnet is removed, the bar retains some respective orientation. Then when you reverse the magnet you are exposing two like poles face to face and thus the magnet just slides right by

But, in x00013's video, the magnets do not slide on the exact same path. Is it realistic that a small magnet would reorient the entire surface of the bar? It also seems odd that several passes of the opposite pole would not re-orient the bar and restore magnetic attraction. No? Yes?

IMO, no reorientation of the entire bar. This can't be the first time anyone tried N vs. S sliding down aluminum, can it!!!!  ??  No way   Time for google.

Mark,

You can say this to OverUnity.com on my behalf.

I remain upset with OverUnity.com

It is never appropriate to be extremely rude to people.  The level of abuse there is too much.

Sterling asked me to post this. I had suggested an appology would be nice.

"Until I hear the they have done something to put a tighter control on inappropriate posts, I will maintain my boycott.

I realize that I tend to be quite harsh myself sometimes, so it is a bit hypocritical of me to expect OverUnity to hold to a higher standard.  But I just feel that the level to which they stooped was wrong."

I suppose it being an alloy probably explains it, but Is it significant that magnets appear to be exhibiting Lenz's Law (or just attraction) to this degree on ALUMINUM? I thought Aluminum was normally considered basically magnetically nonreactive. That magnet slid pretty slowly down that aluminum bar.

EDIT: Just realized the topic is eddy currents, about which I know very little. Carry on.
