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.
Is it safe to hold magnet to brain?
No, it is not safe to hold a magnet to the brain. While small magnets are generally harmless in everyday use, exposing the brain to strong magnetic fields can interfere with neural activity and potentially cause harm. Additionally, individuals with certain medical implants, such as pacemakers, could experience serious complications. Always consult a medical professional before experimenting with magnets near the body.
Why does a magnet affect a video tape?
A magnet can affect a video tape because the tape is coated with a magnetic material that stores information in the form of magnetized particles. When a strong magnet is brought close to the tape, it can disrupt or erase the magnetized particles, leading to loss of data.
What is Something that has two poles is describes as?
A magnet. It is described as a Magnet.
Is there a scale for magnet strength?
They are bar magnet ,horse shoe magnet ,lime stone magnet.
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 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.
How do you erase magnetic information on a credit card?
Take a magnet, swipe it on the magnetic strip on the card.
Is a VHS a magnetic storage device?
Yes, that is why a magnet nearby can erase the contents (hehehe)
What will sticking a magnet on your external hard drive do?
It will quite possibly erase the data stored on the device.
How do you erase a floppy disc with magnets?
To erase a floppy disk with magnets, you would need a strong magnet, such as a neodymium magnet. By placing the magnet close to the disk's magnetic media, the magnetic fields can disrupt the data stored on the disk. However, this method is not highly reliable, as the effectiveness depends on the strength of the magnet and the type of disk. Additionally, using magnets can potentially damage the disk, making it unusable.
Would a magnet erase a computers memory?
yes it is very dangerous and it could harm a computer as well.
How is the MRI used to study cross sections of the brain?
The Magnet
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 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.
Is there any danger to my brain - by wearing eyeglasses that have a magnet on the bridge of the glasses for holding sunglasses?
There is no (proven) danger,especially from a small magnet. If you had a large electro-magnet, maybe.
