Isn’t Technology Wonderful

I was checking out a link that Holte had put into a comment. It was to the famous Eddie Izzard “Cake or Death” sketch, and after I’d watched it I checked the links on the side. One took me to the Neocube. I’ve never heard of this thing before and it was fascinating. I would recommend having a quick look. I’m going to find if I can buy one.

I’ve just bought one on Trade Me (a New Zealand on-line auction site) cost NZ$34 including p&p.
It’ll make a nice stocking filler for Christmas morning for my beloved, who likes to fiddle with things.
Like my personal habits, interests, diet, weight, health, hair style, dress sense, friends and drinking.
Maybe I’ll get some peace now.
Fat chance. :=)
I’m happy in my misery.
I have to have one of these.
Each ball has a positive pole and a negative pole. The positive pole of one ball lines up with the negative pole of the other ball.
Thanks Jerry,
but what about the balls on either side? (see the video)
A magnet can’t have 4 poles, or can it?
No, there would not be 4 poles. If you consider just 2 balls, when they join together, they essentially become one magnet with a positive pole at one end and a negative pole at the other. You have lines of magnetic flux flowing from one pole to the other, in a sense holding the two balls together, and there are no longer separate positive and negative poles where the two balls are touching.
If you add a third ball, the magnet, now consisting of three balls, readjusts itself so again there is a negative pole and a positive pole with magnetic flux encompassing the three balls.
Thanks Jerry,
nice clear explanation, i think I understand it now.
Mother Hen got me one of those for a stocking gift last Christmas. She knows me too well….
They are tiny spheres of Neodymium Magnets, I believe the rating is around N35. These Neo magnets are surprisingly strong for their size.
Now for the super geeks, there is a company that sells raw Neodymium Magnets rated at N45 up to sizes of 3″ x 3″ x 3″ cubes. These magnets are unimaginably strong. They are only shipped by ground and require signature for delivery.
How strong you ask?
Moving these magnets from one room to the next requires some amount of planning. If your hand is between the magnet and something metal, it will literally crush the bones in your hand

Thanks for the information Krell, but squeezing my hand to a paste isn’t quite what I had in mind.
Question: If I remember my school physics, magnets repel similar polarities, so how do the little spheres align in such perfect symmetry.
The NeoCube is way cool!!!
