You can destroy it by heating it above the curie temperature.
Choping it won't work
Throw the magnet at the TV REALLY REALLY HARD.
heating it or freezing it i believe
Yes. A powerful magnet is capable of wiping the entire hard drive.
the circits on the magnet? If so, the paper clip.
Yes you can! Jaime-c your hero
If you take a permanent magnet and heat it up past the Curie temperature (or Curie point, Tc) and cool it, the magnetic domains in the magnet, which were aligned when it was made, will become randomly oriented. When the "magnet" cools, its magnetic properties will have "disappeared" and the you'll have a piece of metal alloy. If you like, you can make a new magnet out of your hunk of metal by heating the metal past the Curie point again, applying a static magnetic field to it, and then cooling it back down in the presence of the magnetic field. That's the way the magnet was manufactured and made into a magnet to begin with.
True. when you heat a magnet you are supplying it with energy therefore the dipoles have enough energy to free themselves form their initial order.
The same way you destroy anything else. melt it in a furnace is the only way because if you chop it one end will be south and the other will be north If you mean "How do you remove the magnetism from a permanent magnet?" There are several ways. You can heat it past its Curie Point. For iron that is about 800C. Stroking one magnet with another in a random fashion will sometimes work. Hammering it will usually work.
I suggest that you incinerate it.
You can heat a magnet to its Curie temperature, which causes the magnetic domains to lose alignment. Alternatively, you can subject a magnet to a strong external magnetic field in the opposite direction to demagnetize it.
probably. only your body is supposed to go in the machine, no disks, devices, phones, or watches
You are discussing magnets with another person. That person thinks that breaking a magnet will destroy the magnets magnetic properties. Write a conversation you might have with the other person to explain why the person's idea is incorrect.
