Subject: Building a thompson repulsion coil

Hi

About 40 years ago I had information on a Thompson repulsion coil and buit 
one.
I
do not recall the particulars but remember an iron rod with a coil and
circuitry
at the
bottom. I beleive the "anti gravity" effect and repulsion came when using an
aluminium ring. Something to do with paramagnetic materials? Perhaps other
metals would also work? Do you have any information
and/or directions/theory for constructing such a coil?

Thanks in advance

Paul
