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 :)

Generally, magnets will not damage a computer unless they are extremely powerful and are brought very close to the hard drive or other sensitive components. Modern computers are designed with shielding to protect against minor magnetic interference. It is still best to avoid placing strong magnets near your computer to prevent any potential issues.
If a magnet is too strong, or gets too close to a computer, it can erase data on a magnetic disk.
no
No, damage caused by a magnet to a computer's hardware components cannot be reversed. Magnets can disrupt the magnetic fields within a computer's storage devices, leading to permanent data loss or hardware damage. It is important to keep magnets away from computers and electronic devices to prevent such issues.
The answer is physical:)
Physical damage, exposure to extreme heat, or exposure to strong magnetic fields can cause a permanent magnet to lose its magnetism. Once a permanent magnet is demagnetized, it is very difficult to restore its original magnetic properties.
Water can temporarily weaken a magnet by disrupting the magnetic force between its molecules. However, once the water is removed and the magnet is dried thoroughly, its magnetic strength should return to normal. Prolonged exposure to water can cause rusting and permanent damage to the magnet.
