Watching TV Physics: CTR television and strong magnet

If you get tired of watching physics videos on your television screen and you happen to have an old CTR (Cathode Ray Tube) tv or monitor you may like to play about in this experiment with strong neodymium magnets. Watch the change of patterns and colours as the paths of the electrons to the screen gets deflected by the powerful magnetic field.

However, if you love your tv set then maybe better not to try this at home. By the way, LCD plasma and LED tvs are not affected in this way.
