In this section you will find our 9mm (0.31") diameter neodymium rod magnets. A 9mm (0.31") diameter x 25mm (0.98") (0.2") thick rod magnet can produce an astonishing pull of 3.2kg (7.05lbs) for a relatively small magnet. Because of the deep depth of field produced by these magnets you can use them for locating ferrous studs in plasterboard walls. They are also used in many common commercial appliances.
