A magnet is by definition magnetic. What was a magnet may now be simply a piece of steel or iron, since losing its magnetism makes it not a magnet anymore.
An electromagnet is only magnetic when it has current running through it, and is not magnetic when turned off.
...yes. That's why they're called magnets.
All magnets have a magnetic field. It is that property that defines them.
All magnets have a magnetic field If the object that you want to move by using the magnet is with in the magnets magnetic field it will move.
the 4 magnetic materials are iron, steel, copper and nickel
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
screws, bolts, and magnets

Nearly all.
No keys are not magnetic at all. Keys do not have iron in them and magnets are attracted to iron.
Magnets can retain a permanent magnetic field. All atoms have a magnetic field which are randomly arranged in the object. Magnets and ferrous metals can retain or temporarily align the atomic fields, thus they are magnetic.

I am not entirely sure what you are after, but you might say that:* It is the nature of magnets to be magnetic. Or:* It is the nature of magnets to be surrounded by a magnetic field.
All objects are magnetic. Some are ferromagnetic (strongly attracted to magnets), some are paramagnetic (weakly attracted to magnets), and some are diamagnetic (weakly repelled by magnets).
Permanent magnets contain magnetic atoms (almost always iron) whose magnetic poles are all (or mostly) aligned in the same direction.
Yes. All magnets of north and south poles. There is no such thing as a magnetic monopole.

Steel is a magnet material, but not all metals are magnetic, like Aluminum.
