Magnets do not destroy electronic equipment but they do influence their behaviour of shadow mask Colour Television Tubes in that the shadow mask can become manetised from a magnet close by. Magnetization causes incorrect beam landing on the pic tube which shows as multi coloured patches on the screen . The effect can be cancelled out by degausing the CRT using a degauss wand . All CTV have an auto degauss system to take care of impurities caused the earths magnetic field .

∙ 8y agoThey do not, with some very important exceptions such as pacemakers and some mechanical hard disks, which rely on magnetic fields to store information. A strong magnetic field can wipe data on magnetic strips, e.g. on a credit card or electronic key. On the other hand, a large surge of powerful electromagnetic energy (it can be created by discharging a large amount of current through a powerful electromagnet, or through the use of a nuclear weapon) can render all electronics useless.

Crust is destroyed near?
Crust is destroyed at the convergent plate boundaries in Earth. In between the oceanic and continental plates, the subduction of the denser oceanic crust takes place.
Why does the magnet attract iron objects?
the magnet attracts to iron by the magnetic field both the iron and the magnet have

can be separated by using a magnet
What type of magnet is lodestone?
Lodestone is an example of a natural magnet.
What happens if you put a magnet on a lamp?
It depends on the type of lamp and the strength of the magnet. An incandescent lamp works literally by running current through the filament to heat it. Parts of the bulb might be magnetic, so if the magnet were ridiculously powerful it might deform or break them. Fluorescent and Neon lamps use ionization, so although I haven't tried it, I'd bet a reasonably strong magnet might affect them. If you have an old CRT-based television or computer monitor you can see how this works by placing a magnet near it -- note, this can cause permanent effects to the picture quality, so either keep the magnet at a distance where the effect is minimal or use a CRT you don't care about. LED lamps are so small and well-constructed that I think they're more like incandescent lamps -- a really powerful magnet might damage them, but otherwise is unlikely to affect them.
Can magnet be placed near electrical appliances?
you can but don place it on them as it can erase memory and it messes around with all the electronics inside the e.g. laptop.
How are magnets is in electronics?
They have a battery that battery has magnet
How can be destroyed?
---- Magnetism can be destroyed by following methods:---- * By heating the magnet, * By hammering the magnet.--->In accordance to this point...allowing the magnet to fall violently* By keeping similar poles of magnets together for a long time. * [not sure about this]by keeping magnet under running water.

How does placing a magnet near another magnet produces a magnet by?
creates magnetic force
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....
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.
Does earphones get damaged if kept near magnet?
yes depends on what type of headphones and how strong the magnet is .
What is the largest magnet of all?
that's easy china has the largest magnet its near China's army...
What happens when you sprinkle iron fillings near a magnet?
when we sprinkle iron filingson a magnet,they stick on it but when we sprinkle it near the magnet they arrange around the magnet in definite curved line forming a systematic pattern
If a bar of copper is brought near a magnet the copper bar will be what?
If a bar of copper is brought near a magnet and rubbed it will get magnetized and would behave like magnet. But this would be temporary and this property would wear after some days.
