Not magnetic. Magnets do not work effectively on gold. If your ''gold'' leaps to a magnet, it is not real gold. There are very weak magnetic forces at play in gold as opposed to iron, nickel, or cobalt which are highly magnetic and used for permanent magnets. High thermal and electrically conductivity. This means it is a great conductor of ...
