Hi guys, I'm just wondering if there is another sort of detector for magnetic fields (of magnets for example) other than the regular gauss-meter. look at this image and tell me if there's actually a machine that can produce a magnificient image like this or if it's just an approximate image that could of been design by photoshop for example with some mesurement with only a gauss-meter. Anything that can help me see the magnetic field besides the baby oil and steel fiber trick and the green gel paper would be great (if you know where to buy a gauss-meter not to pricy too...)
Thank you for letting me know.
Not so hard, take an old CRT tv or monitor, turn it on and hold a magnet close to the screen....Nice!

Lol thanks spider but I don't have any monitor to burn out like this but I remember having fun with this.
no i was speaking more like err a spectrometer, an oscillator ...is there a whaterver machine that could (in the end) give such result. (I'm guessing to that you need to take a course to use theses).
I wonder if a simple hall effect device would give you a reading, and
then it is up to you to scan the area, record the readings, and plot
the results. Hard work.
So I guess there is no simple answer to this huh... Sad we don't have some damn trekkies tricorder, lol
ok thanks paul, i'll check out what a hall effect device is exactly on the net before doing anything. cauz i though it was just a theorie and not a device so i'll have to check it.
Using a lens with a micron thin layer of sandwiched ferro fluid to map external magnetic fields via optic affects of the field on the magnetic fluid. Red, yellow and green radial LED's are spaced evenly; facing inward into the edge of the lens. The light from the LED's warps around the magnets as it passes through the fluid. This is the basic version video with one magnet from youtube user, SirZerp. http://www.youtube.com/watch?v=lD6C6f2nu0U
Check out SirZerp's other videos on viewing the magnetic fields in real time, they are much better than this "basic version video".

Wow thanks a bunch GravityBlock. This a cool finding. it's in my favorites now.
