    They are part of the deflection yoke. If you saw that chunky core wrapped in magnet wire on the skinny end of the tube that’s what that was. They aren’t always permanent magnets, most of the later model TVs used electromagnets, but it’s how the electron beam is moved across the screen. All of them will have very strong magnets somewhere by design.

      Ok, I thought you meant permanent magnets. Of course I know about the deflection coils. There are also some small permanent magnets for the convergence

      Shout out to Philo T Farnsworth!

      He grew up in Idaho and the small town he hailed from had a sign calling themselves the ‘Birthplace of TV’. That sign was frequently vandalized to read ‘Birthplace of VD’.

      Both statements have some validity.
