Magnets present in speakers and electric motors
Technologically obsolete magnets, but still frequently present in industrial use, mainly because of their economical accessibility. They are most commonly found in loudspeakers, electric motors, separators, etc. Production is rather limited, as it requires special tools. High tolerances are difficult to achieve.
