Shadow Graph Problem
#8

I am a little worried.
I put a strong magnet ( the 1/2 Magnet used to pick up parts), near the Horseshoe. The Vane does nothing.
I would expect it to go towards the Magnet. ?????

The Vane moves freely on its axis, The coil is in place.
But shouldn't the Vane react to a magnet. Move left or right????
Wonder if more is wrong than just a weak Horseshoe Magnet.
I believe when power is removed from the Coil the Vane should park itself according to the strength of the horseshoe Magnet.
Anyone work these before?
The Article on the Work Bench sounds pretty simple to test these.
