When we put bar magnet near tv screen why tv colours change what happens?
Answers
Explanation:
normally magnet will not adversely affect the TV screen with the old CRT display and more specifically the colour screens magnets can cause temporary distortion on images on the screen by deflecting the electron beam so they hit the wrong part of the screen
with a colour CRT screen cathode ray tube there is a perforated mask just behind the screen .three separate electron beam shoot through the perforations to hit
different colour phosphor dot if a magnet is placed close to the screen it can distort the screen or even magnetize the screen this can mean that colours are produced wrongly this can result in permanent damage of the tube .
