For those interested:

I've found some other magnet sale sites and one of them sells anisotropic and isotropic ferrite here:

http://www.magnetsales.com/Ferrite/ferrrect.htm

But it's a "call or email for quote" place, so I'll give them a call tomorrow.

Other magnet resources found are (I've not researched these for price or service except where noted):

http://www.supermagnetman.net/index.php (I just spent a decent bit of cash here, so I'll keep you updated on service and quality but these are N50 supposedly and it's the only place I've found selling N50 cones.)

http://www.indigo.com/magnets/magnets.html
(most especially)
http://www.indigo.com/magnets/gphmgnts/strontium-ferrite-magnet.html

http://www.magnetsource.com/Solutions_Pages/pmm.html (no ferrite I see.)

http://www.gaussboys.com/ (didn't really look)

http://www.arborsci.com/SearchResult.aspx?CategoryID=70 (School/hobbyist [like me] stuff, but I saw a radially multi-poled (more than 2) ring mag in there.)

http://www.amazingmagnets.com/index.asp (nice product bundles.)

...and my old standbys of:

http://www.unitednuclear.com/magnets.htm

http://www.rare-earth-magnets.com/

http://www.magnet4less.com/

Just some fodder for your shopping pleasure.

@queue,

Try repeating the experiment, this time leave the 'wand' stationary, and only move the metal extension off of direct contact with the ferrite.


@ All.

      In addition to exx's links,..   you can also use decommissioned inductor-grade ferrites, which are usually obtainable for free from random junk devices.

Chet, make me a list  every mouthy bastard that promised cash if I could get it to run continous.

The boys are back in town.

Hello Folks, in a dash, just thought i'd pop in and say a big thank-you to every one for all the information, and inspiration.
Special thanks to AQ for all his effort, and ofcourse Mr Joe Mayernik (for his letter) just at the right time.

Regards, Bren.

All this mechanical PMM nonsense was old hat hundreds of years ago!

Ok, everyone pack your stuff up and go home... Wikipedia says it's impossible.
