VPI Magic Brick threads deleted

I own, and use 4 of them that I bought when they were first released for about $40.00 each. I thought at the time that I was told that it was grain-oriented iron inside. It is a single block of metal, that I am sure of.

OK you got me, they are a brick, of iron that somehow, creates a magic field of magic? I'm not getting it.. It does something, other than weigh a lot? Grain oriented, does it expand or contract the fields or something in a different way, run as shielding? It's 40.00 of postage? I don't get it..

What is it?

Don't start something and not finish it.. What is that thing? I GOTTA KNOW NOW!.. What is it.... :-)

I have had 3 of them in my system in various places for decades. When one of them goes missing it is usually because my wife needs to glue something. 

oldhvymec,

It is an 8lb,  5" by 3" block of steel laminations...
