note
A common myth: «all metals are magnetic». Only a few are: iron, nickel, cobalt and things made with them, like steel. Gold, silver, copper and aluminium are not. Noun: «magnet», «magnetism»; verb: «magnetise / magnetize». «Magnetic» is an adjective, so you say «a magnetic object», not «a magnet object».
