No, pure gold (24K) is not magnetic. Gold is classified as a diamagnetic metal, meaning it produces a weak repelling force in the presence of a magnetic field, but this effect is extremely weak and not noticeable with everyday magnets.
Why Isn't Gold Magnetic?
Gold does not have unpaired electrons, which are necessary for strong magnetic attraction. Unlike ferromagnetic metals such as iron, nickel, and cobalt, gold does not exhibit permanent magnetism.
When Can Gold Be Magnetic?
Gold alloys (such as 10K, 14K, or 18K gold) can show weak magnetism if mixed with magnetic metals like iron, nickel, or cobalt. Additionally, some fake gold or gold-plated items may contain a magnetic core.
Can a Magnet Test Gold’s Authenticity?
- Pure gold (24K) will not be attracted to a magnet.
- Gold jewelry that sticks to a magnet likely contains magnetic metals or is fake.
- Non-magnetic gold is not necessarily real—further tests like acid or density testing are needed.
