The Halbach Array Meets the Tri-Force Roller.

This may sound dumb but could you tell me how exactly The Halbach Array works? Do i just use magnetic cubes with the north and south facing different directions? do they have to forcefully be held together like they way you have it?   

I placed the North pole faces the way the arrows were pointing.

It is a bit tricky holding each magnet as you put them in place as they will try and right themselves.
But a bit of wood with a 1/4 inch slot should work fine.

Hi Omni

Yep the Sticky Spot still there on the entrance, but seems a bit weaker.
Will make up a few more and try the Rotor.

@CLaNZeR,

Great work, mate, as always. Waiting to see that crucial experiment with the rotor and this arrangement as stator. That nasty initial barrier, prior to the point you place the roller is the culprit. If this helps to overcome it that'll be it. Recall there were suggestions that Halbach array was at the basis of Steorn's contraption. Good luck.

Just had another thought about making bigger lengths as picture below.



As we know, when ever we close the loop on any magnets, including the Tri-Force Gates, they cancel the field force out as no gaps. With this setup will it do the same?

ummm

Decided to make some longer lengths first, so just ordered 80 * 1/4inch cubes and I will make a couple of long lengths that should come out at just 200mm.
It will be interesting too see if it performs as good as the Tri-Force gate on longer lengths.



Will update thread when they arrive.

Cheers

Hi everyone I have been lurking about for a while (few months) reading the magnet motor posts and like what you are doing I thought it was time I signed up and contributed in some way

@CLaNZeR have you tried taking one array and using it in the normal trigate setup as the "roller" but limiting its movement so it doesn't roll and fixing the strong point so it is either infront or behind as it enters and leaves the gates... what I'm thinking is it may be possible to restrict the attraction as it exits and/or help with the sticky point on the next gate... or it could just create a larger sticky spot which is most likely to happen as normally happens

my magnet selection is limited to cylinder and flat neo's so its really hard for me to test this without buying some cubes but I guess they are the next ones to buy for my collection
