    the tape has tiny magnetized particles on it. it's the player's heads that "read" the pattern that the particles are in and interpret that has the video and sound you see on the tv. if a magnet or even a powerful electromagnetic source is brought nearby to the vhs tape it can rearrange the particles on the tape thereby rendering the tape unwatchable as the player can no longer interpret the particles' pattern as anything meaningful to us when we watch the tv.

    The magnets that you might find laying around the house wont do much damage to a VHS tape, if any at all. To induce any kind of change in the tape you need a very strong source such as that from an industrial demagnetizer, or you would have to have the magnet pretty much touching the tape itself for a few days.

    Because the information is recorded trough magnetization.
