China Neodymium And Ferrite Magnets Manufacturer & Supplier 
The reason why magnets can produce a magnetic field and attract other magnetic substances, is based on the unique properties of metallic elements such as iron, cobalt and nickel, some users have asked the magnet used in the gold or cobalt?
It is not gold that is used in magnets, but cobalt. Gold is not a ferromagnetic metal, so it would not be used to make magnets.

The role of cobalt in magnets
Cobalt plays a key role in magnet manufacturing. It not only improves the magnetic properties of magnets, but also increases their stability and durability. Cobalt-containing magnets have higher coercivity (ability to resist external magnetic fields) and remanence (permanent magnetism). For example, a samarium cobalt magnet is a high-performance magnet that has a very high coercivity and is able to maintain its magnetic properties in high-temperature environments.
Unlike cobalt, gold is not a magnetic metal. Metallic to precious metals, its electronic structure dictates that it is not magnetic, and therefore gold is not used in the manufacture of magnets. In fact, the non-magnetic nature of gold makes it useful as a plating for connectors in many electronic devices because it avoids magnetic interference.
Role of Iron and Nickel:
Iron: is the base element of the alloy, providing structural support and a magnetic foundation.
Nickel: As one of the components of the alloy, it helps to regulate the magnetic and mechanical properties of the alloy.
