Electronic memory, I am assuming means magnetic media.
I have placed a hard drive directly on a 22" subwoofer magnet, and was still able to use it afterwards, with all my data.
EMP or electromagnetic pulse provides more of a threat than magnetism. keep HDDS away from microwaves!
What else can I help you with?
Can a magnet erase memory from a vending machine?
i dont think so because a vending machine isn't as sensetive to a magnet as a computer would be.
Can a magnet erase information from memory sticks and computers?
A magnet can only change information that is stored magnetically and if the magnet's magnetic field is strong enough. Memory sticks do not store information magnetically, they use Flash memory which stores information electrostatically. So no, a magnet can not erase information on a memory stick. Computers usually use hard disks which do store information magnetically, so in principle a magnet could erase information from a hard disk. However the magnet would have to be very strong (much stronger than is likely to be available at home) and held very close to the hard disk (probably be inside the computer case or even inside the hard disk case itself) to be able to to erase the information. Computers before the 1970s usually used magnetic core memory instead of DRAM as their main memory. While this stored information magnetically, the construction of the cores as rings made it impossible for any magnet to change the information: the 1 and 0 were opposite directions of magnetization around the ring shaped cores, while an external magnetic field is "linear" not "circular" and thus can't change the state of a core.
Would a magnet erase a computers memory?
yes it is very dangerous and it could harm a computer as well.
Can magnet be placed near electrical appliances?
Yes, it is safe to place a magnet near electrical appliances like refrigerators and washing machines. However, strong magnets should be kept away from sensitive electronic devices like computers and hard drives, as they can interfere with the operation of these devices.
If you put a magnet on a laptop will it erase the memory?
Most laptops are partially shielded from weaker magnetic forces but I wouldn't push your luck with it. Hard drives in particular are highly sensetive to magnetism, and that's where all your data is stored. no it won't erase the memory
Can magnet erase files on usb memory stick?
No it cannot. I did a science fair project on this and i couldn't remove any data from the usb drives.
How powerful does a magnet need to be in order to erase memory from a DVD-R disc?
I don't think you'll find a powerful enough magnet; the DVD-R is an optical recording medium and is unaffected by magnetism.
If you erase memory on a floppy disk with a magnet can you store new information on it?
This disk will certainly have to be reformatted and irreparable damage may have been caused. It is not advisable to do this.
Can a magnet erase a Blu-ray disc?
no
Does a VCR have a magnet?
A VCR (Video Cassette Recorder) uses electromagnets in the record, playback, and erase heads. An erase head can also have a permanent magnet in it.
Can a magnet delete everything on a computer by just putting it on the outside?
No. A magnet only interfers with magnetic fields ... lots of old IBMs used magnetic memory cards and that's where the stories started. It might erase a floppy disk, but an electro-magnet does the job much better than a perminant magnet.
How do you erase a memory?
you hack an acount to earse a memory.
