First of all, don't worry about your CDs or DVDs near magnets. These use "optical" storage techniques, which are not affected by magnets.
"Magnetic" storage - floppy disks, credit cards, hard disk drives - store information by using patterns of magnetization. Basically, they take the information you want to store, and write it onto a special magnetized material. Since this material stores data in the form of magnetization, putting it near a magnet will cause a change in the stored information.

Why are floppy disks used for temporary storage?
Data can be easily loss when floppy disc is placed near a source of magnet or radio wave interference.
Is a floppy disk attracted to a magnet?
The 3.5 floppy disk does have magnetism within them and for this reason, magnets destroying data on the floppy disk fueled the myth about magnets destroying your computer. If you buy a cheap magnet and put it near a floppy disk, the magnet will stick to it. After a few seconds, the information on that floppy disk will be destroyed and you will no longer be able to access the data.
Why shouldn't you not put a phone near a magnet?
Depending on the specific technology you are thinking about, a phone may have data stored magnetically; a strong magnet may delete such data.
Why should a credit card not be kept near a magnet?
Urban myth is it disrupts the data, it doesnt.
Will bringing A strong magnet near a computer disk or videotape cause damage to recorded information why?
Placing a magnet near them for a short time can corrupt or delete the data; this also applies for computer hard-drives and some other storage devices.
Will a magnet damage a computer?
A magnet damages the Hard Disk Drive of the computer dramatically. Because a hard drive's hardware is a magnetic disk drive so the data get written magnetically to the disk. If the magnetic properties are reduced then your data goes with it. So dont ever put a magnet near a computer :)
Why should you not put a magnet near a TV or computer?
Magnets can only harm televisions with a display tube in them. This is because tube televisions use an electron beam to "paint" the image on the backside of the screen. This electron beam excites phosphors which give of light. There are three different types of phosphors, one each for red, green, and blue. When a magnet is placed too close to a tube television, the electron beam will be bent and cause the image to distort, typically by changing the colors on the screen. If the magnet is left close to the television for too long, it will magnetize the metal within the tube and the distortions will be present even if the magnet is removed. Modern flat panel televisions, such as plasma and LCD types, don't suffer from this problem. In the case of computers, the magnet may change the data stored on the hard drive, which uses extremely small magnets to read and write data to a spinning metal disc. If the magnet changes the data stored on the disc, there's no way to recover it.
Is there a way to get information off a old floppy disk?
Floppy disks are an old technology and very prone to corruption in a number of circumstances. If the disk is placed near any magnetic interference (speakers, monitor) if a disk gets to hot, or is exposed to light then data on the disk can become unreadable. It is very unlikely that data on a corrupt floppy disk can be recovered. It is generally considered that the use of floppy disks for day to day file storage is a thing of the past. It would be advised you remove any data you have on floppy disc to a new storage format such as flash memory.
How does placing a magnet near another magnet produces a magnet by?
creates magnetic force
Comparing flash drives and Zip drives, which is less prone to data loss?
Zip drives have less of a chance of losing data but no where near as portable.
What happens when peice of plastic is brought near the magnet?
When some pieces of plastics are brought near the magnet, they will get attracted.
What happen to a metal place near magnet?
It would stick to the magnet....
