I have been doing many experiments with magnets recently, and have hundreds of the most powerful magnets available from e.g.

Be very careful with these. Ideally you'll need a special workshop with only non-magnetic materials around, such as titanium tools, and wooden workbenches, no computers, disk drives, credit cards, etc. nearby, and practice being aware of what you're doing. You must constantly think about what you're doing, as if you're carrying around U235 or nitroglycerine ( I know, I've had numerous close calls, pinched fingers, and shattered magnets, sucking up tools from a foot away, getting stuck to a vise, etc. ). The forces can be in tons for two magnets with 1.2 Tesla flux densities (12000 Gauss) at their surfaces. I've had to build a special tool to separate two magnets that got accidentally got stuck together: http://www.kjmagnetics.com/buildamagnetseparator.asp Hoyt Stearns Scottsdale, Arizona US http://HoytStearns.com
