A comprehensive overview of how non-ferrous metals like copper interact with high-grade permanent magnets in modern engineering fields.
Pure copper exhibits a very weak negative susceptibility to magnetic fields. With a magnetic permeability of approximately 0.9999912, copper is technically classified as a diamagnetic material. When exposed to an external magnetic field, it creates an extremely weak, opposing magnetic field. For all practical engineering purposes, copper is non-magnetic, making it the premier choice for electrical connectors, electromagnetic shielding, and sensor housings where flux distortion must be minimized.
Although copper does not adhere to magnets, its exceptional electrical conductivity makes it a key actor in dynamic magnetic environments. Moving a strong permanent magnet (like NdFeB) past a copper conductor induces circulating electric currents, known as Eddy Currents. According to Lenz's Law, these induced currents create an opposing magnetic field, producing a physical braking force. This characteristic is widely utilized in electromagnetic dampeners, eddy current brakes, and high-frequency induction furnaces.
Understanding the pricing structure of copper-magnet assemblies requires analyzing two separate volatile global market indexes: the LME (London Metal Exchange) copper pricing and the Chinese rare earth oxide (specifically Neodymium-Praseodymium) raw material index. Processing tolerances, surface treatment specifications (such as copper plating, nickel-copper-nickel layers, or epoxy encapsulation), and dimensional complexity directly impact the final custom factory quote.
