The North and South poles are located at the two flat ends of this cylinder-shaped Neodymium Permanent magnet. Cylinder shapes have far more magnetic material between the pole surfaces (height dimension) than Disc-shaped magnets and therefore cylinder magnets have more holding power. The relatively small pole surface areas and the large volume of magnetic material between them is reflected in a magnet that emits a penetrating, narrow and High-Gauss magnetic field. N45 Grade magnetic material used in the manufacture of this cylinder amplifies the strength of the field to an even higher level. Unlike the majority of Block and Disc magnets, Cylinder shaped magnets sit neatly inside slightly larger diameter tubes or pipe-shaped devices and can react in a physical way to ferrous metal or interact with electromagnetic fields to open or close electrical circuits...This has for many years been the operational basis for an alarm activation, sensors, and switching devices because of the largely non-mechanical method in which it functions and the long-term reliability and durability this affords.

The narrow field properties and thin cylindrical shape make these magnets ideal for metal detection and applications where the magnet needs to be grasped and relocated by hand. The cylinder shape extends high above the bonding surface which makes it easier to prise away and break the magnetic bond. This is far more difficult with flat, disc-shaped magnets. The round shape and penetrating field characteristics of cylinder magnets are also useful in the operation of magnetic closure systems for cabinetry and also in the detection and retrieval of metallic objects. Cavities with similar diameters that are drilled into timber can be easily fitted with cylinder magnets. The magnet can attract metal striker plates and secure a timber door in a closed position. Cylinder magnets are also suited to detecting metal fasteners inside wall cavities that are otherwise invisible. Detecting a metal nail or screw inside a wall cavity means the timber frame or stud is also present and this indicates a suitable place to securely hang artwork or heavy audiovisual equipment.
