Re: OFF TOPIC magetic inteference on cableing / switches
Viperm, it appears that you are involving yourself with Magnetic Resonance Imaging. Thoroughly educate yourself, (the basics are really not that complicated), before you jump into this project. The age and strength of the magnet determines the Gauss line at distances measured from the magnet. I assume that these days the magnets are very shielded and the strength of the field does not extend very far from the magnet. Exposing a conductor to a changing magnetic field induces a current in that conductor. Do not forget that magnets attract metallic objects. I am surprised that your were not briefed on magnet safety. Most conductors entering the magnet room usually must pass through a wave guide to eliminate frequencies detrimental to image acquisition.
In the early days I saw people wrestle with unattached pipes in the area of the magnets. I also saw a carpenter loose all of the nails in his pull behind wagon because he did not heed posted warning signs. Do not be responsible for quenching the magnet, if that is still possible!
