Howard Johnson Replication Tube Claim

[carbonc_cc]

I'm not exactly sure the magnets HJ used were really banana shaped magnets.  It looks like they have protrusions on each end creating more of a horseshoe magnet.

Actually in that video he says those are banana shaped and the thing attached to their ends are neodymium magnets to strengthen the whole even more. So the banana shape acts as a channel to "kill" off a pole like you can see in the below simulation. So this concept can and probably should be used as well.

I have been considering this also in my own build but am having some doubts because if I use a center magnet, what I am worried about is exactly the field that will still be possibly too strong in the cavity at the blotch wall, since the true north and south is where the magnet ends and not where the metal extensions will end. The question is will the metal extension ends extend the total field and dilute the blotch wall enough to make it seem like a one piece magnet. I have seen one comparison graphics of this but do nto know how trustworthy such a rendition could be.

Greetings All

This might help with magnet/steel manipulations and may be adaptable for the Howard Johnson problem. I just posted this test on Youtube so every body can see. I had sent a copy to CLaNZeR a few months ago, but now I am releasing it. If you want to just talk on this, I will open another string.

This is what I wrote on the page.

>>Here is a magnet reaction test in a small wheel using steel to redirect the effects of the magnets. Note the acceleration after passing the larger steel plate. All the magnets are facing north to north indicated my the little arrows. Now this is only one of many test that I have done. I hope someone can use this. <<

Hi

I have all component to replicate Mylow HJ motor accept Neo channel  magnet, do you know where I can buy ? 
Please find attached copy for stator magnet which I am planning to use .....
