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.
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.
it attracts
Usually, nothing.
nuthin at all you will have no effect
Nothing. Copper is not magnetic.
you will get seriously hurt

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 :)
Jam/Jelly has no effect on the magnet or its magnetism, but it will cause the magnet to become sloppy and sticky.
It's not magnetic
when magnet is put into a fire, magnetic field of the magnet ll get disappear( depends on type of magnet)
