Hi Mike,

Just so that you don't think you are being ignored, I throw in my 2 cents.

I'm not sure of your mechanical configuration for your proposal, but I would 
think a N to N would REPEL, not add.

Being a retired EE, perhaps you remember the black & white Scottie dog toys 
many years ago.  One approaching the other from the rear cause it to quickly 
spin around! (smile)

Regards,
Jerry

  Subject: Crowded magnetic lines of force


  Hi everyone,



  Here's a question I've always wanted to ask:  Why (if the number of 
magnetic lines of force cut per unit time produces a current flow) is it not 
possible to force two identical magnets together so that they're oriented 
(for example) N pole to N pole.  It seems to me that the lines of force 
would crowd together so that the least movement of them would produce quite 
a strong response in a coil.



  I built a simple vertical seismometer with a 5 pound plumber's lead as the 
weight, a spring and two cow magnets forced together in a 4 inch PVC tube so 
that the resting position in the coil was the point at which the maximum 
lines of force resided.  It made a lot of sense when I designed it but I 
didn't have a good environment in which to test it; e.g. A 500 foot TV 
station antenna within 50 feet; an expressway two blocks away and a location 
inside a TV studio.  To be sure, it was a short period sensor and it 
indicated a lot of local noise.



  I'm not a seismologist (that should be quite evident) . I'm a retired 
electrical engineer who specialized in grounding and lightning & transient 
damage risk mitigation.   I was just  curious and thought I'd ask.
