Magnetic fields located close to a computer can cause undesired effects or even data loss.
Floppy drives, hard drives, and tape storage devices use magnetic charges on a disk or tape for storing data. While hard disks are shielded and protected from all but the strongest magnets, be careful with floppy disks and tapes. Getting a magnet too close to these components could erase data.
Magnets near a CRT monitor can distort the images on the screen.
- CRT monitors, speakers, motors, and generators contain magnets (keep sensitive components away from these devices).
- Solid state storage devices (such as RAM or flash drives) are not affected by magnetic fields.
