The field is zero around a blob of small neodymium magnets ...unless you align them first! Color CRTs get distorted! Make some rotating compasses from rings of magnet beads. (Sell them at weekend flea markets!) These are 8mm and nickel plated. For various suppliers links, see bottom of http://amasci.com/spheres/ These are around $0.35 each if bought in qty. from Mr. George, http://www.supermagnetman.net/...

You shouldnt do that

last thing you were throwing up in the air look up "buzzing magnets!" Two hard shiney supermagnets that bounce together.

what is that last thing you were throwing up in the air towards the end of the video?

where do they sell those message me

take a look at what George Green did with magnets. Think what we could do with super magnets in that configuration. I think our energy problems would be solved to bad anyone who trys to get this technology out gets murdered.

Thats a great program!

So it's like a magnetic circuit? Exactly. And magnetic substances work the same way: if you break up the little magnetic circuits, and instead align them so the "circuit" is routed through the open space outside the material, you've "magnetized" the material. Unmagnetized iron is full of tiny and extremely strong "magnetic circuits." All the fields stay inside.

a magnet will hold it's field indefinitely unless they are subjected to impact repeatedly, or heat in excess or repeatedly, in other words, keep them below 150 degrees or so, and don't let them slam together a lot

t wondering how many i should buy It takes 60 to make a buckyball. I use 8mm, but you could buy lots more if they were 6mm.
