Most paper clips are made from steel. You could make a paper clip out of copper, but the cost would be higher for something that would do the same job.
The answer depends on the material used to make the paper clip, the purity of the copper, the temperature, the thickness of both of the materials, the length of the copper and the paper clip, and a variety of other factors. Generally, copper is a better conductor than the paper clip.
Well, it's certainly a conductor, although not as good as aluminium or copper. On the other hand a plastic paper clip is not a conductor.
When your paper clip is made of (or coated with) more reactive metals than copper, like Fe, Zn or Sn, it might react with Cu2+ ions in your solution. Cu2+ + Fe(s) --> Cu(s) + Fe2+
If it is made of metal, it is a conductor.
Oxygen in the water will cause oxidation of iron minerals in the clip, creating rust.
Magnetizing is a physical change.
The paper clip was not discovered. It was invented.
The paper clip clings to the the magnet
