Um... a non-magnetic material? Like anything made of wood, plastic, fabric, etc.
NO!!! the strength of magnet is not affected by temperature
A magnet. It is described as a Magnet.
If it's a `burned' disk such as a commercial video disk, CD ROM or something you burned on your computer then the answer is no. Burned disks aren't affected by magnets. However, if it's something placed on what's commonly called "floppy' type disks, then yes, a magnet can have an effect on the disk.
Yes, a floppy disk will be affected by a magnet. Many floppy disks have magnetic components so coming into contact with permanent magnets can damage them.
You can rub a permanent magnet against something else that can be magnetized, like a paper clip.
Yes, a wind-up clock can be affected by a magnet, but it depends on the design. If the clock has a quartz movement or uses a magnetic escapement, the magnet can disrupt its function. However, traditional mechanical wind-up clocks, which primarily rely on gears and springs, are generally not affected by magnets since their mechanisms do not involve magnetic components.
Yes - distorted or even erased.
You can use a magnet to test if something is metal. If the magnet sticks to the object, it is likely made of metal. Another way is to check for properties like conductivity or density, which can also indicate if something is metal.
No, salt cannot be separated from something else with a magnet. Salt is not magnetic and does not respond to magnetic fields.
Jam/Jelly has no effect on the magnet or its magnetism, but it will cause the magnet to become sloppy and sticky.
Something called a permanent magnet
yes a Magnet
