Measuring fluctuations of earth's magnetic fields inside a pc ?

[Skybuck Flying]

Hello,

I am wondering if there is anything inside a PC that could be used to
measure fluctuations in earth's magnetic field ?

For now only thing I could come up with is "bit errors" caused in ram memory
maybe caused by transister flips ?
Question is can earth magnetic fields cause any transister or other
component to suddenly flip ? For example if the magnetic field would be very
strong ? I kinda doubt it because if this was the case then this would
happen more often... but then again maybe error correction takes care of
this.

Maybe file systems on harddisks might show some form of corruption... but
these could be caused by simply software errors or hardware crashes.

Another idea might be to observe the speed of the cpu or gpu... for example
doing massive ammounts of calculations... if the earth magnetic field
changes... then maybe this would slow down electrons or maybe even speed
them up... and thus the cpu might start to slow down or speed up
momentarily... even if this would work and be detectable doing massive
ammount of calculations all the time would not be desirable... maybe just
running something that measures the reaction speed of the cpu when it's idle
might do...

However with computers always on the internet and receiving packets now and
then this might be very difficult to do since the cpu will fluctuate a lot
maybe gpu might be more stable but I doubt that too...

Would be funny if it was possible to detect though... maybe under ideal
circumstances/laboratorium circumstances...

I wonder if cpu or gpu speed will change when put into a strong magnetic
field ?!?

(Maybe a fluctuating field is required ?)

Who is going to do this experiment ? Or has it be done already and what
are the results ?!

Also if true... how do they make an atomic clock ?

I would guess it would be shielded from earth magnetic fields ?!

So my theory of cpu speed fluctuations because of magnetic fields might be
already confirmed by the shielding for the atomic clock

Or alternatively the atomic clock is not shielded from magnetic fields and
therefore "they" are being fooled into believing it runs on time !

Bye,
Skybuck

 

[Skybuck Flying]

I also wonder if it's possible at all to "shield" anything from magnetic
fields or earth's (electro(?)) magnetic fields ?!

It seems to go through the earth just fine... so why would it be stopped by
anything on earth ?!?

Seems kinda contradictionatory to me !

Bye,
Skybuck.

 

[Skybuck Flying]

One last explanation is that the atomic clock builders are aware of this and
know that the atomic clock does run inprecise now and then

What would happen if the atomic clock is hit by electromagnetic fields from
an earth quake ?

Hmm...

Bye,
Skybuck.

 

[Skybuck Flying]

This link explains an atomic clock a little bit:

http://www.indepthinfo.com/clocks/atomic.shtml

It does mention "shielding".

No further explanation of this concept is given...

Me go lookup magnetic shielding !

Bye,
Skybuck.

 

[Skybuck Flying]

hmm.. it seems it has something to do with "waves" and/or "particles"...

I guess it's particles after all since they mention "light photons"... so
light could be a wave of photons...

So maybe magnetic fields stuff is waves of electrons or whatever...

Shielding seems to be about to somehow "extract" these electrons from the
air and guide them over metals or so.

This could mean that maybe simple sticking a wire into a soundblaster's mic
input might be able to capture some of these magnetic fields/particles ?!

Maybe this is what causes the "noise"

Me not sure about that.

But suppose it's true... suppose that the "snow" on a television or the
"noise" on a soundblaster is earth's magnetic fields/particles interaction
with the device then at least this is a way to visualize the earth's
magnetic field...

Next time there is an earthquake observe the "snow" on a television to see
what happens !

The snow does look somewhat regular during normal days so maybe this offers
some kind of statistical analysis possibility...

As long as the snow looks "normal" then everything is ok...

During an earthquake build up the snow might start to look weird... or
develop certain statistical properties... maybe more clustering or so...

This could be detectable and offer an early earthquake warning system ?!

Bye,
Skybuck.

I think I now understand why cellphones trigger CRT monitors when they are
"called".

CRT monitors have a deguassing coil... I think the energy from the mobile
phone enters into the coil... triggering a degaussing !

Magnetic fields were also used by the germans to make mines that detect
metal ships ?! Hmm

http://en.wikipedia.org/wiki/Degaussing

Bye,
Skybuck !

 

[Skybuck Flying]

It's kinda interesting... CRT televisions seem to do this when they switch
on... next time I stand back a bit just in case I usually do that
anyway...

Maybe the deguassing of a CRT monitor could be used to whipe the contents of
a harddisk...

Hold the harddisk against the CRT monitor and switch it on... and see what
happens.

I better not do that with my own harddisks ?! This also means a repair
man that doesn't know about this might be screwed

Maybe I try this with a floppy disk to see if the floppy disk gets
"deguassed" by the CRT monitor/television !

Bye,
Skybuck.

 

[Skybuck Flying]

It can even make "modern harddisks" totally unusuable so be warned !

This does prove cellphones can be dangerous...

Anybody carrieing a cellphone and standing next to a coil or some kind of
deguassing thingy could trigger wipeout of data... for example somebody else
standing next to him and holding a harddisk.

Cellphones seem to have some kind of protection from magnetic fields and
such... it's kinda remarkable that they can hold data at all ? but maybe the
lack of a strong degaussing coil explains that... I have yet to see a
picture of a such a degaussing coil ?!?

I wonder if cellphones are disallowed in data centers ? Probably yes ?!


Airplanes probably too for good reason...

It's also kinda remarkable that IBM choose a magnetic medium for storage...
magnetic fields everywhere... kinda surprising that it works at all...

I have been lucky too... my crt television is only 1 meter away from my
harddisks... any closer and I might have had a problem ?!

This could be a good reason to replace it with something else... a lcd based
television to get rid of the deguassing coils to make sure my harddisks last
longer ?!

I am not sure what the range of the deguassing coil/field is ?!?

I did have some file system related corruption lately... but I guessed it
was from crashes in the past ?!?

Also sometimes the flash chip inside the digital camera... and the digital
camera says: "unable to read flash chip..." then I try again and then it
does read it... maybe dirt or is it some magnetic interference going on ?
There are some wifi things here and there from neighbours and such...

Hmm...

Well so far so good !

Bye,
Skybuck.

Hello,

Your CRT. You orient it horizontal instead of vertical, and as you
rotate it, you will see the colors change, because of the Earth's
magnetic flux.

For now only thing I could come up with is "bit errors" caused in ram memory
maybe caused by transister flips ?

You are an absolute retard. Stay OUT of the electronics industry. We
do not need another dope like you.

Absolutely NOT! The earth's magnetic field is four or five orders of
magnitude to small to affect transistors or anything else in a computer. If
there are random errors as you postulate, they likely would be caused by
cosmic rays or high energy particles from deep space. However, all circuits
that are vulnerable use error correction routines to keep the actual error
rate vanishingly small. You could never detect errors in this manner.

The earth's magnetic field is FAR too weak to affect anything in a
standard computer. Memory bit-flips are caused by cosmic rays or other
ionizing radiation, not magnetic fields.

If we all started running in one (rotational) direction at once, it
would cause the earth to spin faster, and so might increase the
field. That idea is no sillier than some of the others in this
thread.

Your CRT.

He said "inside a pc [sic]". So that only works if he's got an iMac.
Anything else and he's SOL.

XTs had integrated monitors, and an XT is even past this dope's speed.

Yes; it contains motors and coils of wire. Take a fast constant-speed
motor with a vertical shaft, extend that shaft with a rod of a good
electrical conductor with a hole drilled through it diagonally.
Symmetrically around the hole, put a non-rotating coil coaxial with the
shaft, and measure the voltage induced in the coil. If the PC has a
disc read magnetically, that system will contain a sensitive amplifier.

I have done that, a stone's throw SW of what is now the RRUTC,
admittedly with a rather larger field.

For similar reasons, it would be good to have approximately half of the
world driving on the left and approximately half on the right.

More dimbulb bullshit. The only ones that did were a few clones,

You're a goddamned total retard.

When the IBM XT PC came out, there were NO clones, you dumbfuck.

Also, IBM most certainly had models with integrated monitors. The
clone began with the 286 class.

If you are going to selectively participate, remove your retarded
filters., and at least attempt to be fucking civil, jackass.

Otherwise, shut the **** up, and keep your retarded, know nothing
horseshit out of my thread branches, you retarded little piece of shit.

Pretty goddamned funny, you coming in here with your hate, declaring
how wrong I am, when it is you that is fucking wrong.

where everything but the keyboard was in one case like the early Compaq.

Wrong again, dipshit.

IBM had a $2000 XT that had an integrated monitor, and no hard drive.

I played nethack for a couple years on one.

Your hatred has clouded your mind, and it has been showing for a
plurality of years now, Mikey. You should seek help for that.

Hell, my "dim bulb" is brighter than your best shot, you hatred filled,
fucked in the head dolt.

You have a garage full of them, and you STILL can't get it right.

My "Fog-O-Graphic memory does a better job than you, even if you had
written it down somewhere.

Clone that, you stupid asswipe.

What do you expect from ALwaysWrong?

The IBM "Luggable" was also in a case much like that early Compaq. It
looked a lot like it, in fact.

Otherwise, collisions would be sure to arise.
