Magnets are most commonly made out of metal, so yes, two metal magnets can repel. But metals such as iron are attracted to magnets even if the metal itself is not magnetized. Iron is attracted to both poles of a magnet, and it can not be repelled by a magnet.

bar magnet :- cuboid shapecylindrical magnet :- cylinder shape
As I recall, Lodestone (magnetite) was found in a place named Magnesia, hence magnet.
One way to know a coin is not silver is to check it with a magnet. If the magnet sticks to the coin, it is not silver. If the magnet does not stick, it still might not be silver. You can test it, but to do that you need a test kit.
It doesn't matter on the orientation, it is the attraction of the magnet to pull the contact and complete the circuit that matters.
by hammering a metal at the magnet xD
It is a magnet or a electro-magnet. If you are trying to use it as a metal detector then you will need a really strong magnet!
the metal object becomes a temporary magnet
A metal pan will not attract iron but a magnet does.
no, the type of metal used is platinum which is unfavorable to metal or magnet.
The exact same way that a normal magnet attracts metal.
Use a magnet. Metal shavings will be attracted to the magnet and pepper will not.
a magnet is a metal thingy that can pull a metal object towards it
Some metals are naturally paramagnetic, meaing that you can induce a magnet field on it but only with a very strong magnet. To actually magnetize the metal itself without a magnet, you would have to make an induced magnet by wrapping the metal around a copper wire and sending electricity through it. It all has to do with the arrangement of the electrons within the metal.
By putting metal piece in contact of other magnet or magnetic field.
Demagnetizing. Place the magnet at the opposite end of the metal from where you magnetized it. Again, the magnet must make as much contact with the metal as possible. Rub the metal with the magnet in the opposite direction that you used to magnetize it.
depends on the metal, iron.
