Is gold magnetic?
Jump to section:
For several centuries, gold has been considered the definitive precious metal in the world. It acts as a great repository of value even today and has been used in jewellery making, coinage, investments, and several industrial applications. Its industrial users are many, owing to certain great properties that the yellow metal has.
Gold is well-known for its malleability, making it a versatile metal to use for industrial applications. At the same time, gold is also well-known for its tensile strength. This property coupled with its conductivity allows it to be used in industry for specialist wiring applications. However, the question we want to address today is “Is gold magnetic?”
Gold and the property of magnetism
Gold does not automatically fall into the category of magnetic metals. For example, if we have a large electromagnet that emits a strong magnetic field, gold is unlikely to be drawn by it. Other metals like iron will be immediately attracted by the magnetic field and will attach itself to the magnet. However, gold does not behave in this manner.
The magnetic attraction of gold jewellery
Often people are surprised when certain types of gold jewellery may suddenly behave magnetically. A dealer may have sold a large ring to you, claiming that its pure gold. However, if it is attracted by a magnet, you may be wondering is gold magnetic? No, it is a certainty that the gold is not pure. There could be iron or nickel mixed into the metal, which causes this phenomenon.
This is one of the ways in which people try to detect the purity of the gold they possess. However, we must bear in mind that even if the item of jewellery is not attracted by a magnet, it doesn’t automatically imply that there are no base metals mixed into it. Base metals such as aluminium, copper, and lead, which are frequently mixed with gold do not have any magnetic properties.
Often metals like copper and nickel are mixed into gold to create colours, which are popular amongst buyers. Also, precious metals like platinum, silver and rhodium are frequently being used by the industry to make the surface of the gold harder and scratch proof. These metals do not have any magnetic attraction properties.
Recent scientific developments
Although gold had always been considered a non-magnetic metal, a recent scientific discovery has put forth the possibility that gold can be magnetised through heating. But is gold magnetic? Researchers at Tohoku University in Japan discovered that by spinning the electrons and inducing heats at the same time, a small degree of magnetisation can be achieved in gold. In the experiment, a thin film of gold was used, and a magnetic field was applied in parallel with the flow of heat. Researchers believe that such discoveries can reveal the unknown properties of matter that may have useful industrial applications. It could be useful for innovative and new areas of science such as thermoelectric uses and energy harvesting.
