haha no. What are you trying to protect against? renegade pieces of steel attacking your computer? if youre talking about one of those ferrite/ferrous round magnets that are stuck around various usb cables, those protect against interference caused by the magnetic fields around AC power cables.
creates magnetic force
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.
You can't physically "break" a computer (mother board) with a magnet. However, you can corrupt the hard drive, which is essentially breaking it. But you'll need an extremely strong electromagnet because modern hard drives are shielded against such threats. In other words, a refrigerator magnet won't do it.
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 :)
static, static can damage the things inside just like a magnet.
Your computer uses magnetism to store information. The binary code used by your computer to transmit information at the most basic level, 1s and 0s, are stored by your computer in the form of magnetic charges. 1s are represented by magnetized bits and 0s are represented by unmagnetized bits. (8 bits make up a byte)Due to this, putting a magnet on your computer may damage information stored in it, as well as possibly corrupting the ROM in your motherboard. ROM is the read only memory that your computer uses to know how to start up.For these reasons and others, I would highly recommend not putting any magnets anywhere near your computer.
The iron filings experiment demonstrates that a magnet's force can pass through certain materials. Placing iron filings on a piece of paper and then placing a magnet underneath the paper will cause the filings to align along the magnetic field lines, showing that the magnet's force is able to pass through the paper.
You cannot make a magnet stick directly to aluminum because aluminum is not magnetic. However, you can make a magnet stick to aluminum by placing a magnetic material, such as iron, in between the magnet and the aluminum surface.
electromagnetic induction
No, but placing a video tape on a speaker will ruin the tape
Unless you scratch the disk while placing the magnet on the disk, then nothing will happen. A magnet would have to be powerful enough to extract the hemoglobin from human bloodcells to be able to effect the disk.
This is not a change at all. However it is physical when you use a magnet to physically seperate (by manetic force) .
