	Just looked at your picture.  Where'd you get those neat binding
posts?  Look like something out of the distant past, but really useful. 
You haven't describee the rest of your systemor the before and after
magnetic field gap performance; please do.  By the way, I think the
magnetic field in the gap would be stronger if you used a closed
magnetic circuit (C-shaped iron or steel rod or bunch of sheets, with
magnets along one leg and the gap between the open ends of the C.
