Magnetic field affecting electron stream flow causing similar visual effect looks the same.
I think it's more about the color pixels being magnetised.
Actually it is phosphorus molecules start to radiate when hit by fast moving electrons. Magnetic field is used to direct electron stream.
A magnetic field is used to steer the beam but it
won't work well on a color screen if that screen is magnetised.
Google AI:
Color CRT (Cathode Ray Tube) televisions and monitors were equipped with a built-in degaussing coil.
Purpose: The coil was designed to remove unwanted magnetization from the metal shadow mask inside the picture tube.
How it Worked: It created an alternating magnetic field that decreased in amplitude, effectively "degaussing" the tube every time the TV was turned on from a cold start.
Significance: Without this, stray magnetic fields (including Earth's magnetic field) could cause color distortion, or "color impurity," which appeared as patches of wrong colors on the screen.
Sounds/Symptoms: When turning on a CRT TV, a distinct "whoomp" or buzzing sound is often heard, which is the degaussing coil activating for a few seconds.
Limitations: If the internal coil failed, or if the magnetic distortion was too severe (e.g., from a nearby speaker),
an external handheld degaussing coil or "wand" was required to fix the color issues.
