I know this is a bit dated but this thread is how I found this forum in the first place so I wanted to add my .02 cents to the subject...
I had practiced only a little basic beginner qi-gong in the past. Synchronized breathing while attempting to feel the qi points on my palms.
I ordered the Peter Ragnar "magnetic qi-gong" program with the magnets and began practicing. Within a couple of days of steady practice I was able to feel the subtle magnetic push-pull emanating from my palms.
One side of me thinks "Maybe its just like riding a bike and once you finally get it you've got it for good" ... the other part of me thinks "using the magnets accelerated it."
Can I prove any of this OBJECTIVELY , no.
Do I believe the magnets helped , yes.
