Can a strong magnet harm my computer?Thanks

The parts of your computer that could be affected by magnets are:
Floppy drives
Hard drives
The monitor.
In theory magnetic and electric fields are closely linked, so a magnetic field will have an effect on electronics. However, if you have a magnet strong enough to actually have a noticeable effect on a computer, then you are probably dead from it affecting the iron in your blood.
For real world magnets they will have no effect on most electronics.
Floppy drives. Floppy disks can be erased by magnets. But who cares these days?
Hard drives. No readily available magnet is going to be strong enough to get though the shielding and reach down onto the platters of a hard disk and alter the information. This is not a problem.
Monitors. CRT monitors are very susceptible to magnetic fields. Even the Earth's weak field can have an effect (Turn on your monitor, then rotate it though 90 degrees and see what happens) There is a degauss coil to take care of weak effects, like the Earth's field, but playing with a magnet on the screen can have a result that the degauss coil can not undo.
If this happens to you then just take the monitor to your local TV repair shop and ask them to degauss it. They will use a much more powerful degauss wand or ring that will clear it up in about 30 seconds.

Not .... really.
Yes, and no, kind of......moreso, I'd say NO.
Here's why:
"For venerable floppies, this statement holds true. We placed a 99-cent magnet on a 3.5-inch floppy for a few seconds. The magnet stuck to the disk and ruined its data.
Fortunately, most modern storage devices, such as SD and CompactFlash memory cards, are immune to magnetic fields. "There's nothing magnetic in flash memory, so [a magnet] won't do anything," says Bill Frank, executive director of the CompactFlash Association. "A magnet powerful enough to disturb the electrons in flash would be powerful enough to suck the iron out of your blood cells," says Frank.
The same goes for hard drives. The only magnets powerful enough to scrub data from a drive platter are laboratory degaussers or those used by government agencies to wipe bits off media. "In the real world, people are not losing data from magnets," says Bill Rudock, a tech-support engineer with hard-drive maker Seagate. "In every disk," notes Rudock, "there's one heck of a magnet that swings the head.""

Yes a magnet can harm you computer.
There is a possibility of wiping the hard drive.
If you have a magnet on your monitor it will change to color of the screen and could cause permanent damage.

Magnet and computer is completely different sides. All electronic thing are kill by magnet. Magnet absorb all power from electrical thing. So this is the impotent massage that Magnet is harmful not only for the computer for all electronic thing.

yes.. of course.. but there are magnets that are insolated.. like the magnets on your computer speaker it is insolated so it is safe.. unlike others.. the magnet can destroy your monitor.. just by placing it beside the monitor it will make a pink discoloration, that pink discoloraton is just a sign that the magnet is doing some harm... in the part of your System unit where your hard-drives and CPU is located.. while the hard-drive is doing a process and you will put a magnet beside it.. the needle will happle the steel disk in your drive..

yes magnets harm computers. They generate magnetic field which effects monitor...try to keep your speakers quiet far from your monitor..

It will ruin the drive if you don't have the manufacturers low level format utility. There are 2 levels of formatting for a hard drive. First the low level format which puts in timing marks on the drive, maps bad sectors to the spare sector area and so forth. Then there is the high level format done by the operating system. It is simpler to do just remove any partitions on the drive then format the drive using the operating system.
