Is Gold Magnetic Yes or No Gold Properties and Physics

Sep 10, 2020 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.

Pure gold is incredibly soft and 99.9% pure gold jewelry, or 24K gold, is less common. However, it’s a good gauge to help you understand value. 24K gold is virtually pure gold and thus more expensive than smaller karat jewelry. If you encounter 10K gold, that means it contains 10 of 24 karats of gold.
