Mistery Metal?
« on: January 19, 2009, 02:31:21 AM »
I am looking for some explanation to the mystery metal that is on the one side of a hard drive magnet. Any info i could get would be fantastic.

Perhaps I missed you're point?

What is mysterious about the metal or what it is doing?

alots of Newbies are using Polls to post for the first time and most are also trolls.
don't ask me why..., i don't know.
testing forum's features perhap ?

anyway.
the metal use to shield hardrive magnets is simply mild iron, nothing special there.

So does the mild iron just redirect the magnetic field or does it... trap it in a sense. I understand that what im saying doesnt make sense but please bear with me. I do tank all of you for helping me on the subject.

The iron just provides a 'connection path' for the field. Something like 'shorting' one side of the magnet.

The unusual part is the polarization of the magnets. Most magnets are polarized at the ends. these are on the edges. The effect is the assembly seems to be magnetic on the voice coil side only.

This is very interesting. So is this the best possible "shield". To my understanding there is no material that can totally kill a magnetic field. Is this accurate? I know about the MUmetal but im not exactly sure what that is or does. To my knowlage that only blocks magnetic interference?

I would like to change my question above. Not kill a magnetic field but just block one.

=============    Iron, will flux closing
    S              N        POL  (closed)
###############     MAGNET
    N               S        POL (output)

        -----------             Moving coil  in the Magnet field

Attention. This HD Magnets are not magnetized on -edges-!
(1 cm from ends)
2. They have 4 Poles !
3   If they flux will closed from 2 Magnets (also from 2 single magnets!)
THEN the Magnet have 2 Time the Power on ech "output"

TAT is ALL , Fully normal, notimg Mystery.


TINK this way:

Iis you connect 2 magnets face to face  tis way

  N
  #
  #
  #
  S
  N
  #
  #
  #
  S     Then the  force each side is 2 times higher than from an single magnet

   SO IF YOU connnect now an Iron plate ( size as the magnet beween the 2 Magnets,
   than you have no differentces to the first-one  !!!
   If you take this "Mystery Iron ::. YOU WILL understand TAHT IS NOT AN SHILDING !
   It is only an (magnet-flux conducting)) IRON

Pese's description is  more correct than mine.

As far as I know there is no way to shield from a magnetic field. Your only option is to 'redirect' the lines of flux.
Some may say redirection falls within the definition of 'shielding'. It does but people raise this question almost weekly.

This was very well covered in this thread.

I spoke with the inventor of the patent. My report is on the same page.

The implications of this are very great if you know how to apply the shielding.

Yeah, an existing magnetic field cannot be "killed", the flux is there and needs to
go somewhere. But it can be redirected through a path that is more "permeable"
to the flux than another path.

It is interesting to see how often people try to find a flux shield that actually
blocks the flux.
Obviously, all of them have the same idea in mind: if we can block the flux
on one half of a wheel that has magnets mounted on it, we can make the
wheel turn itself because we can make the attraction or rejection of the magnets
drop away on that side while the rejection or attraction on the other side
of the wheel stays the same.
Just like the idea that we could make a wheel move perpetually if we could
shield one half of the wheel from gravity.

Unfortunately there is not really a way to produce that type of shielding,
that simply makes one "pole" of a magnet "go away".
There is "shielding" that allows flux to flow through a specific path,
and so we can plan where the flux path is and thereby cause the magnetic field
to no be "projected" outside of that path.
This is what happens in your hard drive: the iron (could be nickel or cobalt)
is a very good flux path and better than the air or the other metals used
(probably nonmagnetic metals like aluminium, copper, nonmagnetic steel alloy,
that type of thing) and so the magnetic field does not extend outside of that path.
And so you don't "feel" a magnetic field outside of the flux path.
Nothing is really "shielded".

If we collect rain water in a gutter and allow it to flow to a drain, are we "shielding"
our street from rainwater? Or are we allowing the water another, easier, flow path?
;)

Koen

OKOK. I think i get the facts of "shielding". To move onto my next question. The OC MPMM. Is this a hoax? Why isnt the world working on free energy if it is not? Government problems? lol jkjk But seriously I have found quite a few "self propelled" magnet motors on the net. If any of them worked would that not solve the problem we are all tryin to figure out here?

Jes , but this is not the mystery metal in Harddisks.
Coal-slage . Wondering...  See this Link to shown this patent:
