1Know what ends up in this category
Atypical magnets are pieces that do not fit the standard block, cylinder and ring grid. In practice that means:
- Oversized blocks such as 100x50x30 mm, where a normal catalogue size no longer exists.
- Magnets with a radiused face, marked with an R in the name, shaped to sit on a round surface.
- Magnets with a through hole for a screw, including countersunk versions.
- Large rings with outer diameters beyond the standard range.
- Magnet fishing magnets and complete sets for treasure hunting.
If you cannot find what you need among the standard shapes, this is the category to check before asking for a custom part.
2Read the R value in the product name
Names such as 40x20x10xR95 or 50x50x30xR157 mean the magnet has a curved face ground to that radius in millimetres. A magnet with R95 is shaped to sit against a cylindrical surface of roughly 190 mm diameter, because the diameter is twice the radius.
These pieces are made for drums, rollers and rotating assemblies where a flat magnet would only touch along one line and lose most of its hold. Match the R value to the actual diameter of your drum before ordering.
3Treat the pull force in this category as genuinely dangerous
Most magnets here sit in the highest force band, above 50 kg. A magnet of that class snaps shut across several centimetres, crushes fingers instantly and cannot be pulled apart by hand once it has closed onto steel.
Plan how you will hold, transport and release the magnet before it arrives, not after. Choose a lower band if the application does not truly require this much force.
4Work out the handling before the first use
- Keep large pieces separated by thick non-magnetic spacers, for example wood or several layers of cardboard.
- Slide a magnet off a steel surface sideways instead of pulling it straight off.
- Handle the biggest pieces with two people and never between your body and a steel surface.
- Keep them at least 1 metre from pacemakers, hard drives, payment cards and measuring instruments.
5Check the working temperature
Most atypical pieces are standard N grade for use up to roughly 80 °C, with some available for 81 to 120 °C and 121 to 150 °C. Because these magnets often end up in machinery rather than on a desk, confirm the value in the product parameters before mounting them anywhere warm.
6Ask if the shape you need is not listed
The range shown here is what we hold in stock. For dimensions, radii, magnetisation directions or coatings that do not appear in the catalogue, we can quote a custom solution, which is the same route we use for magnetic separators and other industrial applications.
Tip: For magnet fishing, the pull force printed on the magnet is measured on a flat plate in direct contact. A rusty, irregular object lying in mud will be held by a fraction of that figure, so buy a rope rated well above the magnet and expect the real recovery weight to be far lower than the nominal number.

Frequently asked questions about atypical neodymium magnets
Anything outside the standard block, cylinder and ring grid: oversized blocks such as 100x50x30 mm, magnets with a curved radiused face, magnets with a through hole for a screw, large rings and magnet fishing magnets. These are catalogue products held in stock, not one-off custom parts.
It is the radius of the curved face in millimetres. A magnet marked R95 is ground to sit against a cylindrical surface of roughly 190 mm in diameter, since the diameter is twice the radius. These pieces are intended for drums and rollers, where a flat magnet would touch along a single line and hold only a fraction of its rated force.
Most pieces here exceed 50 kg of pull force, which is enough to crush a finger caught between the magnet and a steel surface, and enough that the magnet cannot be pulled off again by hand. Keep large magnets apart with thick non-magnetic spacers, slide them sideways to release them, handle the biggest pieces with two people, and keep them at least a metre away from pacemakers and electronics.
No. The stated figure is measured with the magnet in direct contact with a thick, flat, clean steel plate and pulled straight off. A rusty, irregular object lying in mud, held at an angle, is retained by a small fraction of that value. Choose a rope rated well above the magnet and expect the practical recovery weight to be far lower than the nominal number.
Yes, custom dimensions, radii, magnetisation directions and coatings can be quoted on enquiry, the same way we handle magnetic separators and other industrial applications. Send us the dimensions, the working temperature, the environment and the required holding force and we will propose a solution.
Most of them are standard N grade for use up to roughly 80 °C, with a smaller number rated for 81 to 120 °C and 121 to 150 °C. Since atypical magnets often end up in machinery rather than in an office, check the maximum working temperature in the product parameters before mounting them anywhere warm.
This category holds the pieces that fall outside the standard grid: oversized blocks, magnets with a radiused face for drums and rollers, magnets with a through hole for a screw, large rings and magnet fishing magnets. Most of them sit in the highest pull force band above 50 kg, which is why we state the exact force, coating and maximum working temperature for every piece and explain how to handle it. If the shape you need is still missing, we quote custom magnets and complete industrial solutions on enquiry.
