Your question: How do magnets affect TV screens?

When a magnet is brought close to the picture tube, the interaction between the flying electrons and the magnetic field creates a force that throws the electrons off course. Now the electrons are hitting the screen in places they were not intended to strike and the picture becomes distorted.

What happens if you put a magnet on a TV?

When you put a magnet near the tv, it diverts the electrons away from where they should go, and so the wrong phosphor spots light up and you don’t get the right colours. … Some tv’s have a degaussing coil inside them that re-sets the magnetism when you switch them on, so the colours go back to being correct.
