PROBLEM TO BE SOLVED: To improve the quality of sound of various kinds of analog cartridges. SOLUTION: A magnet which improves the sound quality of an analog cartridge by constructing such that a magnetic force thereof is storing on a side of required polarity, while on a side of an opposite polarity where the magnet is not is use, the polarity of the magnetic force is changed and the magnetic force is suppressed during the process in which the magnetic force goes through 0, by which factors deteriorating the quality of sound are removed.
