It attracts the electron beam. The beam is initially aimed using an electromagnet at the rear.

Hi. Bad idea! The TV tube controls the electron beam from the cathode using magnetic fields. Your magnet interferes with this control. Older sets can hold the magnetic distortion on the grid and need to be "de-gaussed" to get rid of it. Newer TVs do this every time they are turned on. (That's part of the crackling noise you sometimes hear.) LCDs are not affected.

It deflects the electron beam - The semi permanent 'damage' is due to the fact that the magnet magnetizes the iron mesh just behid the glass. The screen needs to be degausses if that happens.

Moving Electrons in the TV set are deflected from their paths by magnetic fields
