Is Gold Magnetic? Yes or No? | Gold Properties and Physics

 · Pure gold, also known as 24k gold, is not magnetic. If you have just purchased a 24k gold bar or ring and it attracts a magnet, you are in trouble because that product isn''t pure gold. Other gold types, such as white gold, have a weak magnetic pull due to its small amount of added nickel or other hard metals.
