Yes, and they can be quite powerful at doing this. The bad thing is that they can be hard to release from the item you are pulling if you can't turn them off "Permanent magnets".

No, paperclips are not permanent magnets. They can temporarily exhibit magnetic properties when in the presence of a magnetic field, but they do not retain magnetism like permanent magnets do.
No, electromagnets are not permanent.
Electromagnets and permanent magnets differ in how they are created and their magnetic properties. Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets with a fixed magnetic field. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
magnets have potential energies associated with them and whatever object they are interacting with (must have charge to interact...). this energy does work as the force is exerted on said object, the direction being dependent on the charge. so yeah magnets can pull stuff

A permanent magnet can affect magnets and electromagnets.
Permanent magnets can be found in stores that sell hardware or industrial supplies, as well as online retailers. Specialized magnet stores or suppliers may also carry a wide variety of permanent magnets for different uses.
I dont think you can ---- If you super-heat the magnets, it will demagnetize them, thus stopping the "pulling power" of the magnets. Basically stick the magnets in a vat of super boiling water, that should be sufficient enough heat to demagnetize the magnets.
not really. is depends on what kind of magnets they are.
Natural magnets, such as lodestones, have a permanent and persistence magnetic field. These permanent magnets can also temporarily magnetize material such as iron, nickel, and cobalt.
No, permanent magnets can also be attracted to ferromagnetic materials such as iron, cobalt, and nickel. This attraction is due to the alignment of magnetic domains within the materials, resulting in an attractive force between the permanent magnet and the ferromagnetic material.
