TIL about how CRTs work

Could we actually see what the image left would look under CRT circumstances?

Sorry, I see a degauss button I press it.
- In the late 90s, there were some monitors in our school library that had some serious grounding problems. You could literally touch the screen with one finger, touch your victim with the other hand, and have your pal repeatedly turn the monitor off and on rapidly at the physical spring-loaded switch - and at some point, they'd get an uncomfortable-but-not-painful shock.
  Highly entertaining, guaranteed a bollocking, and after that it was back to the degaussing CHUNNNNNNNGUNGUNGUNG sound. Satisfying as fuck.
  
  Shit, I remember degaussing monitors. I also remember picking up a power supply I was working on before lunch, not remembering that I had powered it on earlier to test it, and the shock throwing me against the wall.
  Ah, the good old days.
  
  Back when we used to head over to someone's house for a LAN, there was one guy that had a massive CRT monitor and if he degaussed while our monitors were close to his they'd all degauss.
  None of ours were able to trigger other monitors, only his.
  
  Your class was a lot smarter than mine.
  Mine weaponized the track balls from mice. Ever been pelted with one? Not fun.
  Good way to train fine motor skills though because we had to learn how to use the mouse without the track balls. Had to move the two little wheeled sensors inside yourself. Bet most of our class still knows more keyboard shortcuts than normal to this day.
- I used to work in a computer lab, open plan, where we all had CRTs. I sat across from the main DB admin, who had TWO monitors for all the work he was doing (wild stuff to have dual CRTs back in those days.) Due to the layout, my monitor sat in-between his, facing the opposite way of course. I loved degaussing my monitor because:
  It would degauss both of his and
  The EM fields were so strong between them that my monitor's image would flip entirely upside down before snapping back into frame while making just the craziest electronic noises, colors dancing all over the screen. Gorgeous stuff! I wonder if anyone has tried to recreate a degaussing effect using shaders to simulate the process?
  
  I remember fucking around with magnets to pull or push a desktop image and being scolded by a supervisor. “You’re going to break it!”
  Break what? The photons? All I’m doing is the same thing the monitor itself is doing.
- Modern generations will never know what's been lost.
  When I was a kid we had an electric piano with a degauss button. It was more fun than learning to play.
