A nail can be magnetized by being hit with a magnet 50 or so times, alternately, if a nail or other piece of metal which is attracted to magnets (these metals are called ferromagnetic by scientists) is left near a strong magnet for a long period of time (a few days to a few years depending on how strong the magnet is) it will become magnetic.
No.
You can magnetize a paper clip by passing it repeatedly over a large magnet.
You cannot magnetize a permanent magnet because it is already magnetized.
magnetize
No
never
magnetize
No its not a metal.
When a ferromagnetic substance is magnetized, the magnetic dipole moments of the atoms in the material line up in one direction and are able to produce a net magnetic field. This has to do with iron's elctron configuration on the atomic level.
Typically you can magnetize iron or steel by exposing it to a strong magnetic field. Common "ceramic" magnets may not be strong enough, but you may need a strong rare earth magnet or a strong electro magnet.
No. There is no metal in a diamond to magnetize.
duct tape a magnet to it.
