Magnetism is a property of certain metals that has important implications in the world of precious metals. While many precious metals are not magnetic, some metals such as iron, nickel, and cobalt are highly magnetic. In addition, some precious metal alloys may contain small amounts of magnetic metals, which can affect their magnetic properties.
Magnetism is an important consideration for precious metals companies, as it can affect the way that metals are processed and handled. Magnetic metals can interfere with certain types of testing and analysis, which can make it more difficult to accurately determine the composition and purity of a sample.
Palladium, platinum, and rhodium are all precious metals that are used in a variety of applications, from jewelry and investment to catalytic converters and electronics. While these metals are not typically magnetic, they do exhibit some interesting magnetic properties. For example, platinum and palladium are diamagnetic, which means that they are repelled by a magnetic field. Rhodium, on the other hand, is paramagnetic, which means that it is weakly attracted to a magnetic field. These magnetic properties are important considerations for the processing and handling of these precious metals, as they can affect how they are tested and analyzed.
Magnetic susceptibility testing is a non-destructive technique that is used to determine the presence of magnetic metals in a sample. This method is often used to verify the purity and authenticity of precious metals, as it can detect even small amounts of magnetic impurities.
