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 ?! ;) :)
Bye, Skybuck.
