A moving coil cartridge is a type of phonograph cartridge used in turntables to convert the mechanical vibrations of a stylus into electrical signals. It consists of a small coil of wire attached to a magnet, which moves within a magnetic field as the stylus tracks the grooves of a vinyl record. This movement generates an electrical current that is then amplified to produce sound. These cartridges are known for their high fidelity and detailed sound reproduction. They typically offer a more dynamic range compared to other types, such as moving magnet cartridges. However, moving coil cartridges are often more expensive and require a compatible phono preamp for optimal performance.
