The field is zero around a blob of small neodymium magnets ...unless you align them first! Color CRTs get distorted! Make some rotating compasses from rings of magnet beads. (Sell them at weekend flea markets!) These are 8mm and nickel plated. For various suppliers links, see bottom of http://amasci.com/spheres/ These are around $0.35 each if bought in qty. from Mr. George, http://www.supermagnetman.net/...

People who don't know what they're talking about should not attempt to be helpful.

It's hard to tell in the video, but the magnets are about 6" away from the monitor.If you place supermagnets against the screen, the color change will persist, but there are several ways to "degauss" the iron screen inside the CRT.The real danger is in magnetizing the steel frame. If you place supermagnets directly on the edge of the CRT, Or sit them on the monitor case, you can cause color-warps which can never be degaussed.
