Poles Reversing

[mikestocks2006]

What also makes sense to me now is the delay in watching the Steorn motor run where it hits a point where it sort of slowly stops some kind of device gets slowly lifted and the device spins again, could this indeed be the delay of the Ceramic switching poles?

Hi CLaNZeR,

Could you please post the video, showing the stop and go aspects of the device?
Thanks

Hi Gyula

For your info I was playing with a small Neo magnet today towards a smaller ceramic and it was interesting to see when using a smaller Neo Magnet on a Ceramic that the poles do indeed swap back pretty quickly when the neo is removed.
When I used a Big neo as shown in this thread the Ceramic is reversed for good and I still have the Ceramics here that are still reversed from the original experiement the other month.

Hi composer,

Can you give some more info (web link, paper reference etc) on how quick the a ferrit magnet recover and change back to its original poles after the ''treatment'' from the stronger magnet?
Thanks,  Gyula

Hi Mike

I will try and dig it out, I had a quick look on the Skynews Video as I thought it might of been this one, but it isnt.

The one I remember was one of the earlier videos that showed the device rotating a barrier being lifted as the device came to a halt.

Will go see if I can find it.

Mike update on video footage

Seems Sky news Archive has nicely butchered their clip to remove any of the pictures of the devices.
But found a copy on youtube

This is not the one I remember seeing that interested me at first as I know there is another one I think from one of the other News channels that shows the lifting bit I am trying to explain.

But for now if you look at 1:00 into the video you will see the stop start action I am talking about.

I will continue the search so I can show you what I mean!

Hi Clanzer,
Ahh when you say you reversed the field you meant it was permanent, sorry I missed that in the original description.
Is the central region on the reverse side of the ceramic magnet flipped as well?

Hmm, so you get first repulsion, you go past the point of no return, then you get attraction. All we need to do now is figure a way of reversing these two forces and we have it.
On the ceramic magnet you have a change in polarity, so if you have another magnet near the face (1mm gap) in attraction, when the field flips it will be repelled and able to perform some work.
After the 2nd ceramic magnet is repelled then the main neo magnet can move onto the next ceramic magnet, so it would not be a smooth motion, but stop start.

People were talking about mu-metal and shields, when all along it could what you have just demonstrated, neo magnet and a ceramic magnet as the switch.

I am going to rack my brains now to see if I can figure how you can make a repulsion followed by an attraction into useful work.

What happens if there is a neo magnet attached on the underside of the ceramic magnet and you try to bring the first neo magnet into contact the surface of the ceramic magnet?
I am wondering if this is some kind of avalanche effect where by it reverses the polarity then repels the other neo magnet.
