A magnet will pick up the iron screws but not the brass.
The method to separate steel nails from brass screws is called magnetic separation. Since steel is magnetic while brass is not, a magnet can be used to attract and separate the steel nails from the brass screws.

Use a magnet. Brass is non ferrous and will not be attracted to the magnet.
Most screws are made of some metal or another.
The most common screws are steel, which is made from iron. Screws manufactured for special purposes are made from other metals, including aluminum, brass, bronze, copper, stainless steel, and titanium. Some screws may contain alloys of more than one metal, and steel screws may be plated with zinc, nickel, copper, etc.

A fair amount of steel (iron with a little bit of carbon), used in frames for beds and stools, screws, radiators, washing machines, computers etc. Copper is used for wiring and piping, lead used to be used but now is being phased out. Lead is used for flashing, on roofs around brickwork. Aluminium is sometimes used in windowframes, pans etc. Zinc is used to gavalnise steel screws and steel fencing. Brass door knobs are sometimes used and brass screws for decorative purposes (brass is a zinc and copper alloy).
No, steel is generally heavier than brass. Steel is an alloy of iron and carbon with a density greater than that of brass, which is an alloy of copper and zinc.
