Turning on and off a Pernament Magnet Field

There is a material in hard drives, after having played with them a bit today, that I noticed had a semi-shielding effect to very strong neo mags. It's the material to which the magnets inside hard drives are glued. 1/8 of an inch of it allowed me to "shield" iron components from the magnetic field. Only very small items would stick. although the magnet was directly attached to the other side. Neither the sides or edges of the material would allow me to stick a small screw to it, it would just slide off. However the magnets would pull the same item directly to them if exposed to the open face of it from over an inch away. It would however allow me to attract another strong magnet. I thought they were steel, however if it were the pole, although weaker, would simply transfer to the steel if that were the case.  Perhaps this material could be used to shield a rotor with an iron front edge on it, on a SMOT type motor to overcome the sticking point. This could perhaps be done mechanically somehow as on a torbay motor(ramp/wheel). Just thought I'd throw that out there.

Any thoughts?

The magnets in a hard drive are for moving the actuator arm back and forth via a coil on the arm itself ,to allow the read heads to move in and out over the surface of the platters.

The material I'm talking about has the magnets for moving the coil in a sandwich configuration above and below the actuator arm, which resembles a rocker arm laying on it's side with finely wound coil on the back of it. (these would make excellent stators in the torbay device, if you could get enough similar ones to make a model). At any rate, these magnets are probably 42s if not higher. VERY strong. And sandwiching them between these materials negates one side of the magnet's field almost completely. Hence why in spite of the STRONG magnets in a hard drive they don't emit a strong magnetic field outside the case of the drive itself. They are perfectly capable of doing so at their strength.  Makes me wonder if the material is bismuth or diamagnetic graphite. But that would eventually wear down the magnet's poles so.... I'm not sure. At any rate I'll try to give you an idea below of the configuration.

obviously it's much more rounded than this, and it's actually more of 1/3 of a circle than half.

I don't remember typing that.... At any rate,

If you can peel some of that material off and stick it on that cut, it would probably help alot.

Exactly, perhaps you could eliminate the pushing of the stators back down altogether, and allow gravity to do that job instead of the topcap.

Hi Jack, Nice work on your motors!

I have a couple questions about the magnetic valve that I think you can answer without putting your patent application in jeoprody.

1) By what percentage is the magnet's field reduced when in the "OFF" state?

2) You originally stated that the means of turning a magnet OFF was by way of applying a ~180kHz square wave across the magnet (perpendicular to the field). The connections to the magnet had to be conductive, and as close to the Bloch wall as possible. Subsequently, you stated that the same effect can be produced by 2 other means, namely with a DC voltage, and by a mechanical means of some sort. My queston is: Which of the 3 means is the most FUNDAMENTAL, or BASIC (simplest) way to achieve this effect in the magnet?

3) Which of the 3 means above are in your patent application? All 3?

Comment: There must be much more involved than just applying an AC or DC voltage across a magnet to turn it off, otherwise, you have already given away the secret. Since no one has succeeded with the simple test, AND you have stated that you would not reveal all until you receive the patents, I assume I am correct. I surmize then, that it is pointless to experiment with the simple test, as the real means has yet to be revealed, and thus would be fruitless.
