Viewing magnetic fields with CRT monitor ...

[DeepCut]

Hi.

Have googled this but not come up with much.

I'm thinking if i remove magnetic shielding from CRT then placing a magnet near the screen should show field.

Any one know much about doing this ?


Thanks.

Tenbatsu, thank you very much

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 Channel for more videos on viewing the magnetic fields in real time, they are much better than the "basic version video", and here his more information about this technique, http://www.scribd.com/doc/28943933/Photographing-Magnetic-Lines-of-Constant-Scalar-Potential

The Dynamic Etalon is another method, and was conceived and developed as an economical tool for magnetic research.  Basically, this unique lens is a Fabry-Perot Interferometer combined with a modified Hele-Shaw cell. The nano particle mixture within the lens respond dynamically in the presence of a magnetic field.

A real-time holographic representation of magnetic flux is clearly visible to the observer or image recorder, unlike a typical computer generated pattern plotted by software. http://www.youtube.com/watch?v=byxCYvDjFRM

Excellent thanks very much.
