hi there i am a new member of the yahoo group. i am a student ,looking forward to construct a magnetometer as my B.E final year project , and that the main...
Hi all! The group has become quite silent! Please post about your progress on your own magnetometers or graphs with nice data or ideas for designs or ... Don't...
Hi Hannes & all, I'm still here Hannes, i've not won the lottery or anything & moved away or anything, lol. It has been quiet though in this forum lately. I'll...

Hello All: I have been lurking on this list for some time now, and I am not technically as proficient as most of you, but I do have a question. For some time...
... Barry, In theory you could use rebar in a flux-gate magnetometer, but in practice you’re probably doomed. The problem is two fold, rebar has lousy...
... Hi Mark! Good! ;-) If I would win in the lottery, I would certainly be still around, but would be away for a few days each month to look after my newly...
Hi Doug, I am working a version of your Tekatch-Welch Magnetometer that you describe at http://crocus.physics.mcmaster.ca/Magnetometer/TW/ and I have some...
Hi David, Anthony Tekatch did the tests on the separation required. (We were trying to see if we could get them at the opposite ends of a 12-inch (or smaller)...
How far away from cars does a magnetometer have to be to achieve ~1 nT signal to noise? Assuming that the signal of interest is the earth's field and...
Just looking at the “HIGBEE MAGNETOMETER“ looks like it is made up of a standard compass on one and on the other end a DC electric hi-current meter that...
OK, the Squid controller is indeed for a Josephson junction magnetometer device, too sensitive for earth's magnetic field, and requiring liquid He as Charles...
In my pursuit for a temperature controled environment for a fluxgate (Fgm3)magnetometer, I built a vault shown in the photo section. I surrounded a styrofoam...
Sounds quite good. At 18 in of depth, you should see only 1-2 degrees of change over a day anyway. Make sure the water containers are very well sealed, or else...
I agree with Don about the water in the box. Plastic bottles and so forth transmit moisture, even if sealed. A technique I've used is just to put in dry,...
Thanks. The sand sounds like a very much better idea. John N. ... __________________________________ Do you Yahoo!? Yahoo! Tax Center - File online by April...
Right, Charles. if necessary it can be dried in an oven. Don ... From: Charles R. Patton [mailto:charles.r.patton@...] Sent: Tuesday, April 13, 2004 12:11...
Hi everyone! Does anyone know about 3 small sensors we find under motors of floppy disk readers? I've used some of them and it's seem to work to build a simple...
Hi Pat, They are no for magnetometers at all, they are no way sensitive enough. I tried ages ago & found i had to amplify them alot & ended up with loads & ...
Hi Doug I am not sure what you mean by "locking and pulling" in your last message about testing various FGM-3h sensor separations. How do you compensate for...
Hello all, This will be a bit lengthy, but I feel I should be complete... So here you are :-) My name is Rick and I've been fascinated by the sciences since I...
Rick, One quick though occurs to me. I’m assuming that the five gallon paint can is made of steel. This would be a bit of a magnetic shield that not very...
Hello Charles, Thanks for the quick reply. Nope, my paint bucket is one of the typical plastic ones. I was afraid that if I used a metal container, I'd suffer...
Hi Nightrunner & all, I was very interested to read about the drift you're getting. I am using an ic, HMC1022 to detect magnetic field, far easier than going...
