This delicate but strong Gold Coated Neodymium Disc is one of our smallest magnets and appeals to those wanting a more refined appearance. Museums, galleries and exhibitors often choose these gold plated magnets as they add a more sophisticated element to a display. Craftspeople and hobbyists find this disc useful as a clasp and model fixing purposes. There are many functional benefits provided by the gold plating due to its unique properties including corrosion-resistance and thermal and electrical conduction. These properties make them suitable for many specialised applications such as componentry in electric devices that form part of security equipment including warning systems and monitoring devices.

Why are some magnets coated in gold?
Gold coating provides several functional benefits to magnets. It offers excellent corrosion resistance, as gold does not oxidize, and enhances thermal and electrical conductivity. These properties make gold-coated magnets suitable for sensitive or specialised environments, such as electronics, medical devices and security systems.

Are gold-coated magnets purely decorative?
No, while the aesthetic appeal of gold-coated magnets makes them a popular choice in displays and presentations, the gold layer also serves a practical purpose. Gold coating protects the magnet from environmental damage, provides conductive properties, and is long lasting in technical applications, making these magnets both functional and visually appealing.

Where are gold-coated magnets commonly used?
Gold-coated magnets are often used in museums, galleries and exhibition displays, where their refined appearance adds a sophisticated touch to mounting or fastening systems. Magnets coated in gold are also popular among craftspeople and hobbyists for use in clasps, closures and model fixing. Gold-coated magnets are an important component in electronics for monitoring and warning systems because they are tough, durable and have excellent conductivity properties.

Why are gold-coated magnets important in electronics, security and monitoring systems?
Gold-coated magnets are used in these systems because the gold plating offers several important functional advantages, such as Corrosion Resistance. Gold doesn’t oxidise, making the magnets more durable and suitable for long-term use in sensitive environments. Gold coated magnets have excellent electrical and thermal conductivity, which means better performance in electronic circuits and sensors. Gold is non-reactive, which helps maintain signal integrity and makes these magnets compatible with other materials in precision devices. When combined with powerful neodymium magnets, the gold coating allows for small, high-performance magnetic components that are ideal for security equipment, warning systems and monitoring devices. These properties make gold-coated magnets a reliable choice for advanced and mission-critical electronic applications.  Gold Plated Permanent Magnets Neodymium Tiny Disc 3 x 2mm N38
