What Shape and Size Magnets are Available?
Find out all of the available shapes and sizes that are available.
Available Magnet Shapes
Permanent magnets come in a huge variety of shapes and each has its own unique benefits. The geometry of a rare earth magnet determines how the magnetic field lines are arranged from the north pole to the south pole, so the shape of the magnet is a very important factor where precision is required.
In most applications where precision isn’t required, certain shapes are required to fulfil different uses. For example, if you’ve drilled a hole into a surface, you may want a disc magnet to fit flush inside. In any case, we can custom manufacture magnets to the most precise and obscure shapes imaginable and you decide the strength of the magnet.
Available Magnet Sizes
We can custom manufacture magnets as small as 0.3mm and as large as 165mm in any direction. In addition, the size tolerance of custom manufacturing is very precise and stands at -/+0.05mm. These size restrictions apply to all types of magnets.

Adhesive Magnets
Adhesive magnets can come in all shapes and sizes and they have an adhesive backing on the largest face of the magnet. Correctly apply the adhesive magnet by pressing the adhesive side into a smooth surface, like metal or plastic, and holding for 2 minutes. The adhesive will bond to the surface. Smaller adhesive magnets are often used in jewellery, magnetic therapy, Warhammer models, science projects and general DIY. The operating temperature is generally 60°C so they are not recommended for extremely hot environments.
Angled Mitre Magnets
Angled mitre magnets are long magnets that have one flat edge and one 45° angled edge making them perfect for use in mitre joints. They are also commonly used on vehicles, machinery, woodworking projects, general DIY and household appliances.
Arc Magnets
These are curved magnets that are measured as outer radius (OR) x inner radius (IR) x height (H). Arc magnets are most commonly used in electric motors, generators, alternator rotors and stators.
Block Magnets
These are rectangular in shape and measured as Length (L) x Width (W) x Height (H). This is one of the most common shapes of magnets and can be useful for a huge array of applications. These bar magnets have even been known to fill an entire surface, acting as magnetic tiles.
Branded Magnets
Branded magnets can be any shape, however, they’re most commonly produced as block or disc magnets. These have your logo or personal design on your magnet which is achieved with a high-gloss sticker or laser engraving on the magnet.
Channel Magnets and Pot Magnets
Mounting and pot magnets are magnets that are encased in a protective steel casing. They most commonly have a countersunk or counterbore hole in the centre to be drilled (or mounted) onto a wall, ceiling or surface.
Counterbore Magnets
Counterbore magnets have a flat-faced hole in the middle which enlarges to a coaxial hole. These are measured as diameter x height x (counterbore hole diameter). They are used in many applications that require the magnet to be bolted to a component or surface.
Countersunk Magnets
Countersunk magnets are designed to be screwed into place so the screwhead is flush with the magnet. The size of the countersunk hole is often measured as the diameter of the smallest hole. Uses for countersunk magnets are almost endless, but the most common applications for countersunk magnets include general DIY, woodworking, magnetic lock mechanisms, magnetic clasps and retail displays.
Clyinder Magnets
As the name suggests, these magnets are cylindrical and are measured as Diameter (D) x Height (H). They are categorised as cylinder magnets when the height matches or exceeds the diameter of the magnet. The magnetic field has a longer distance to travel from each pole which means they are widely used for sensors.
Disc Magnets
These are circular magnets and they are measured as Diameter (D) x Height (H). These are very versatile magnets and perfect for slotting into a drill hole or partition. Disc magnets have large magnetic poles due to the wide and flat surface. To increase the strength of the magnet, simply increase the diameter, height or grade. The power of the magnet will continue to increase until the height matches and exceeds the diameter.
Horseshoe Magnets
Horseshoe magnets are the most recognisable magnet shape in the world and have become the international symbol to visually represent a magnet. These u-shaped magnets are measured as length (L) x width (W) x height (H) and are most commonly alnico magnets. They are popularly used in education, science and research.
Ring Magnets
Ring magnets are circular magnets with a hole in the centre and they are measured as outer diameter (OD) x inner diameter (ID) x height (H). They are often used in speaker systems, motors, sensors and science experiments.
Pyramid Magnets
Pyramid magnets are magnets that have a wide base that narrows at the top. They are measured as base length and width (L/W) x top L/W x height. Pyramid magnets are one of the most powerful magnets available since their tip focuses the magnetic flux better than most other shapes. The flux of these magnets are so powerful that they have been used for magnetic therapy in whales which was only previously done by using superconductors.
Top Hat Magnets
Top hat magnets are magnets that have a flat circular top with a smaller circular bottom. These are measured as outer diameter (OD) x inner diameter (ID) x height (H). These top hat magnets are often used in applications where the smaller diameter fits into a recessed area.
Tube Magnets
Tube magnets are long magnets that are measured as outer diameter (OD) x inner diameter (ID) x height (H). They have a straight circular hole through the middle and are often used in magnetic separation equipment and linear actuators.
Sphere Magnets
Sphere magnets are circular magnets that are measured as diameter (D). These magnets are perfectly rounded magnets in all directions and are often used in DIY, education and research. Small 3mm, 5mm and 8mm sphere magnets were very popular as people used them to create structures, however, they are widely banned due to safety concerns after several people swallowed them. If you would like to make magnetic structures, we recommend using Magna tiles. These are plastic magnetic tiles and people use the magnets to build structures and are very popular amongst hobbyists and children alike.
