The metal you must use must be made of of iron or steel, it won't work if the item is made of something like aluminum, brass, lead or plastic because those materials are non-magnetic!
A steel screwdriver is a good thing to try to magnetise because you can use it to pick up small screws if you drop them inside something that's so small you can't get your fingers into it!
Lots of people try to make a magnet using both poles of a horseshoe-shaped magnet but then it won't work as well because the second pole of the magnet will reverse the magnetising effect of the first pole.
All you have to do is keep stroking the metal, always going in just one direction only and then pick up the magnet at the end of each stroke.
Pressing hard, stroke the metal over and over like that with just one pole of your magnet until the metal gets magnetized.
A good permanent magnet should produce a high magnetic field with a low mass, and should be stable against the influences which would demagnetize it. The desirable properties of such magnets are typically stated in terms of the remanence and coercivity of the magnet materials.

I believe you can combine iron and strontium to make magnets.
Nickel.
Iron
Several different metals can be used in magnets. Iron is perhaps the most common metal used in permanent magnets, but alloys such as Alnico (Aluminum, Nickel, and Cobalt) can also make very strong permanent magnets.
Permanent magnets are used in food processing to remove metal fragments resulting from the manufacturing process. Magnets are also used in recycling centers to separate iron. A magnetic resonance imaging machine uses a magnet.
Permanent magnets can be used in a compass to find north, or they can be used to the magnetic field you need in a motor or generator. Spinning a wire at a right angle through a magnetic field creates electricity in the wire.
I guess Al (aluminium), Ni (nickel) and Co (cobalt).
Gluetonium
Iron
permanent magnets are not used in electric bells because they do not make the bells to ring well

False permanent magnets can but electromagnets need a running current A+
Yes Permanent magnets is the term used to describe magnets that are always magnetic, an non permanent magnet would be an electro magnet which is only a magnet when an electric current is put through it.
Cerium is a chemical element with an atomic number of 58 and the symbol Ce. Cerium alloys are used in permanent magnets, thus making it magnetic.
no it is not . a temporary magnet is used instead. If you use a permanent magnet, the doorbell will keep on ringing
