Vane is not magnetic, it is attached to a magnetic armature.

I have read that article and realize the Vane itself is not Magnetic.
It does ride on a Metal Pin (Armature) The Pin is aligned between the magnet ends

See this
https://www.youtube.com/watch?v=IzRFEhuu0HE    (KEEP in mind this one is mechanically different than mine)

Mine does not deflect at all with Magnet applied to side with coil energized or de energized
The light source is just to cast a shadow, as far as I know it does not effect Vane movement.

The Metal Armature is not being effected by a Magnet. The Top of the Armature is oval , like a race trrack.
The ends of the Ova armature  align with the ends of the Horseshoe shaped magnet
I can't figure why the Armature does not respond to a magnet in its path. I would think it would follow a magnet,

Learning.

Wish some one with the same one would jump in. This must be a very early version, I see they replaced it soon into production. The Type in the YouTube seems to be more common.
