The magnetism of a piece of magnetized iron can be weakened by exposing it to high temperatures, hammering or dropping it, or by placing it near other strong magnets that have opposite polarity.
An unmagnetized piece of iron has its atoms pointing in different directions, and opposing each other. When the iron is magnetized, the atoms are mostly pointing in the same direction, and the fields add together.
A piece of iron can be temporarily magnetized by stroking it with a magnet in the same direction multiple times. This aligns the magnetic domains within the iron, creating a temporary magnetic field. Charging the iron by induction, where it is brought close to a strong magnet, can also temporarily magnetize it.
To demagnetize a magnetized iron nail, simply repeatedly heat the nail and then let it cool slowly. This process will disrupt the alignment of the magnetic domains within the nail, effectively demagnetizing it.
To align all the domains in a piece of iron, you can subject the iron to a magnetic field. As the iron is exposed to the magnetic field, the domains will gradually align in the direction of the field, resulting in the iron becoming magnetized.
A piece of iron can be induced to become magnetized by placing it in a magnetic field. The magnetic field aligns the magnetic domains within the iron, creating a net magnetic field in the same direction as the applied field. Once the external magnetic field is removed, the iron will retain some level of magnetization.

When you touch a piece of iron to a permanent magnet, the iron can become magnetized temporarily because it can align its domains with the magnetic field. However, once the iron is removed from the magnet, it will lose its magnetism over time. The iron itself does not retain a permanent magnetism like the original magnet.
A magnet is a man-made object, made from minerals that are magnetic or iron that has been magnetized.
If the piece of metal is a magnet it will attract another piece of iron. You should be able to feel this attraction as the two become very close. It's magnetic field can be "seen"( that is the effect) by placing iron filings on a piece of glass and place the magnet beneath the glass. Otherwise it is not a magnet.

The most common element will be iron, but in general could be any transition metal with unpaired electron.

Yes. In this case, the magnet will induce magnetism in the iron, which is originally unmagnetized. Once the magnet is removed, the iron may return to an unmagnetized state; unless the magnetic field near the piece of iron is very strong.
No, a plastic spoon is not magnetic. Plastic is not a material that can be magnetized. Magnetism works on materials that have magnetic properties, such as iron or steel.
A temporary magnet is a material that becomes magnetized when placed in a magnetic field but loses its magnetism once the external field is removed. Common examples include iron and steel. Temporary magnets are often used in applications like electromagnets and magnetic strips on credit cards.
