More pup stuff..

   Thought you may like seeing the single coil magnet
stuff like polarity- notice the white/black magnet indicating
poles.
The gauss meter reading the magnetic strength and poles. N to right. (+)
 
The two one inch magnets will be used to charge the uncharged
materials.
I haven't done it yet but they are to be mounted in a way
that the pup can be passed between them for charging.
 
Now it's nice to have that polarity checker so I can confirm..it's under 10 dollars
IIRC. If you're going to replace pups...I'd get one.
