I did it messing around at work and it must do something to the powder coating inside the tube.

You can actually induce residual magnetism in the aperture grill that is beyond the ability of the start-up degauss pulse (that grunty noise you get every time you turn on any CRT) to eliminate. Tweeter magnets are very good at this.

When you took the phone off the screen, the top right corner would warp and yellow. Put it back, and everything went back to normal. I'm not sure how that happened...
just brew it! wrote:The phone could've induced an opposite permanent field in the CRT shadow mask, which would've partially canceled out the deflection of the electron beam caused by the phone? Having a little trouble visualizing it, but I think that's at least plausible. Maybe?
