Potential references.

Just a few. --Alan del Beccio 18:24, 18 November 2007 (UTC)

I added the one of those potential references that mentioned an electromagnetic field on the MA page--in other words, I didn't watch 13+ hours of video to fill out this page, so I probably missed a few references. Since I did add a few references I went ahead and removed the PNA tag. If you believe this page still requires attention (more so than an "average" page) please replace the PNA tag. 08:29, 10 February 2008 (UTC)
