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.
We had to constantly remind people not to leave their disks on top of the monitors in those days, because on some models the degaussing pulse was enough to erase a floppy disk.
I was also proud of my ownership of a large speaker magnet which had a highly directional magnetic field, and could cause tube monitors and TV’s go all paisley from about 20 feet away. I kept it stuck to the back of my steel garage door when not in use to keep it well away from all monitors, disks, and tapes.
