A moving magnet cartridge is a type of audio device used in turntables to convert the physical vibrations of a vinyl record into electrical signals. It contains a small magnet attached to a cantilever, which moves in response to the grooves of the record. This movement generates an electrical current that is then amplified to produce sound. These cartridges are known for their simplicity and durability. They typically offer a warm sound quality and are easier to replace than other types, such as moving coil cartridges. Many audiophiles appreciate moving magnet cartridges for their balance of performance and affordability.
