Hi Jim,

No, these magnets are the normal 2 pole types.
However they are from such, but, of the older
type...i.e., 4 normal 2 pole magnets per
assembly.  Newer ones were 4 pole, with either
one magnet per assembly, and rarer, 2 such
magnets per assembly.

Interesting note, somewhere in my internet
travels, one site mentioned that some of the
early (~1972)"super magnets", were a composite
of platinum and another/more ingredients.
Likely they were very limited in production.

I would agree; a 4 pole would have alot of
problems floating...ha.

I noted the same tipping effect on my first
levitation stand also, but didn't pursue it,
at the time.

Thanks,

Meredith Lamb
