Magnetic devices should not be kept near televisions | Picture on the TV screen gets disturbed with magnetic fields

magnets near tv Televisions are used widely all over the world. Certain precautions and guidelines are to be followed to avoid some dangers.

Magnets which can produce magnetic fields should be kept away from the television. Moreover, devices like telephone, radio, speakers, mixer etc which work with magnets should not be kept near the television in any situation. Because, the picture that is visible on the screen of television is due to the light emitted by electrons that hit the back portion of screen. The electrons hold the information related to the picture visible on the screen. These electrons scan the thin phosphor screen continuously and so picture is visible on the screen of television.

If magnet or magnetic devices are brought nearer to the screen of television, then the outer field gets obstructed due to the inner magnetic field. The electrons which are under the influence of magnetic field inside the television get distracted from their actual path. Due to this, blurring appears on the screen and so picture is not visible clearly on the screen. In case of color television, colored marks can also be detected on the screen. That’s why any magnetic device should not be kept near the television within three feet distance. Then only, picture is visible clearly on the screen.
