Guest wired Posted July 8, 2004 Share Posted July 8, 2004 does anyone know how to measure the earth's magnetic field at a particular location? how about a reporting source where I could look it up? Link to comment Share on other sites More sharing options...
senexa Posted July 8, 2004 Share Posted July 8, 2004 Two helpful links for you: Instruments for measuring the magnetic field: http://www.mines.edu/fs_home/tboyd/GP311/MODULES/MAG/NOTES/instover.html Map of current measuring stations: http://www.ocean.washington.edu/people/grads/mpruis/images/magobsmap.gif Link to comment Share on other sites More sharing options...
Martin Posted July 8, 2004 Share Posted July 8, 2004 does anyone know how to measure the earth's magnetic field at a particular location? how about a reporting source where I could look it up? do you want to measure the geomagnetic field at your location? or would you rather just look up what it is, and not have to measure it? if you just want to look it up in a table, then what is your location or what is your latitude/longitude (there should be some table---I wouldnt mind knowing too) Link to comment Share on other sites More sharing options...
ydoaPs Posted July 8, 2004 Share Posted July 8, 2004 the saa (south atlantic anomaly) is pretty interesting. it is a big dip in the magnetic field of the earth. Link to comment Share on other sites More sharing options...
Guest wired Posted July 9, 2004 Share Posted July 9, 2004 thanks for the links senexa martin - i would rather just look it up, but it would have come from some place recognized as an official reporting source. Link to comment Share on other sites More sharing options...
STING Posted July 9, 2004 Share Posted July 9, 2004 What is the purpose of measuring the earth's magnetic field at a particular local??? just curious.......mikeyboy Link to comment Share on other sites More sharing options...
Guest wired Posted July 10, 2004 Share Posted July 10, 2004 sting - I have an upcoming test for "magnetic effect" when an electrical device is operated. In order to accurately gage the result, you have to know the "background" magnetic effect due to the earth. Link to comment Share on other sites More sharing options...
ydoaPs Posted July 10, 2004 Share Posted July 10, 2004 Be sure to get a good detector, because the electric device probably won't make much of a difference. What device are you plugging in for the test? Link to comment Share on other sites More sharing options...
