Broli,

As far as I know the corner pieces are NOT magnets as in your drawing.

Yeah I wasn't too sure about those. But then I saw that the outside of the ring was colored blue as well so I thought the blue indicated the south pole. Why else would he put them there. Either they are needed for the principle or they are just used to hold the 4 bar magnets together.

@ broli,

maybe there is nothing there at all in the built version or simple blocks of wood, which Howard uses a lot in some designs.

The rubber magnet is crucial, so he says elsewhere. He says that there is an interaction between magnets that changes character depending on what the magnets are made of. In some gates of his he used rubber and neo magnet sandwiches.

I thought rubber magnet as in it being able to bend. That's the only way I can think of for Johnson making such a radially magnetized magnet. But I have a lot of knowledge in these thing and below is an attached version that uses regular axial magnetized magnets to get the same field. You have to watch out though. If you truely want the same setup as him without magnet one should use two conducting hoops with opposing currents going through them. Then you will have the same setup but that relies on current again  ;D. Also do you have an illustration of the magnets on the cart? I believe I can figure out how it works if I analyze it.

Just download the book broli and you can see for yourself what he says. I'll just quote the post of mine with the link here.

G'day all,

Howard Johnson published a book in 2006 entitled The secret world of magnets. It is still in print as far as I know.

However, there is a copy of it on the net in pdf form. I don't know if this breaches copyright laws, I should think so, but never mind. It is fascinating and amongst other things explains the construction and workings of his gate.

You will find it here:  http://www.scribd.com/doc/34317/Spintronics-The-Secret-World-of-Magnets-2006-by-Howard-Johnson?autodown=pdf  Well worth the read.
