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.

Why should you not put a magnet near a flash drive?
USB sticks also called flash drives are a small rectangle of computer memory. Magnets reset or wipe all information on computer memory.
Does a compass point to north only in winter?
Nope. It should point that way all the time unless you put a magnet near it and cause the needle to follow that magnet.
What happens if you put a magnet near your heart?
nothing at all
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 :)
What is the result you should see if there is a magnet in the doorbell when it is connected?
put a magnet up to the door bell
Process of separating iron fillings from a sulfur powder using a magnet?
If you put the magnet near the iron fillings, they will be drawn out by the magnetic pull of the magnet.
What items that can be damaged by a magnet?
Pretty much any electronics with wires. The metal inside the wires and generally attracted to the magnet. For example, it is a TERRIBLE idea to put a magnet next to or on a computer or computer monitor. It will distort anything and everything inside the computer.
How do you set your computer to have a WEP code and WPA?
You put a magnet on the hard drive.
Co za asy?
They don't. Don't even try putting a magnet NEAR a computer. If you do, the area where you DID put it on, your computer will be spoilt because all the metal parts inside will be mixed up and you only have a 30% chance of fixing it.
How would you determine if a metal is magnetised?
You can put a magnet near the metal. If it gets attracted or repelled, then it is magnetised
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.
