Howard Johnson Replication Tube Claim

I do not see any holes in them.

Hmm.
I guess I found the type of magnet Mylow uses for his runner magnets.

Have a look at the upper left one.

It even has the same fixing hole:

The question still is, how these magnets are polarised and what they normally are used for.

Hmm,
maybe you are right Paul,
it really needs a better verification of the polarity of the Mylow magnets.

I still found  another magnets, that looks simular to his
stator magnet:

And it says that it is magnetised as a horshoe magnet.

I just did another long term magnetic viscosity test -->

1. I took a dead horseshoe PM (either alnico or hard steel) that had hardly no strength.
2. Placed two ferrite PM's on each end of the horseshoe PM.
3. Remove ferrite PM's in ~ 30 seconds.
4. Measured horseshoe PM. No measurable difference.
5. Placed two ferrite PM's on each end of the horseshoe PM.
6. Remove ferrite PM's in a few minutes.
7. Measured horseshoe PM. Slight stronger.
8. Placed two ferrite PM's on each end of the horseshoe PM.
9. Remove ferrite PM's in ~ one half an hour.
10. Measured horseshoe PM. Significantly stronger.

This shows a long term magnetic viscosity.

In the end maybe we're both correct, Stefan. It's possible mylow's PM just after being remagnetized was the typical horseshoe orinetation, but maybe his machine slowly modifies it. After all, we're talking about extremely weak PM's-- hard iron and alnico. So it doesn't take much to mess them up. Take a look at mylow's field mapping of the alnico C cores. They're so lopsided it's not even funny.

Sorry, yes, you are right, I mixed this up as the Mylow magnets had some yellow
color points in them making them look as holes in a quick low quality preview.
Now I see in his video watched in high quality that these are just colorized dots
printed on there...
