Magnets are or rather were used to record audio or video on cassettes media earlier (which had/have magnetic tape in them on which data was recorded using magnet), which have now (still used) but taken over by optical media (CDs, DVDs, Blurays).

Hard Disks/Drives in computer also use magnets to record on them.

What else can I help you with?
