1. Sliding resistance

*Warning: On a vertical wall, the magnet retains merely a fraction of its max power.

2. Steel saturation

*Thin steel (e.g. computer case) significantly weakens the holding force.

3. Temperature resistance

*For standard magnets, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.09

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The Pc (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher Pc value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

The presented product is an exceptionally strong rod magnet, manufactured from modern NdFeB material, which, with dimensions of Ø10x15 mm, guarantees the highest energy density. This specific item is characterized by a tolerance of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 2.60 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is created for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 25.51 N with a weight of only 8.84 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using two-component epoxy glues. To ensure stability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø10x15), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 15 mm. The key parameter here is the holding force amounting to approximately 2.60 kg (force ~25.51 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 10 mm. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized through the diameter if your project requires it.

Pros and cons of neodymium magnets.

Benefits

Apart from their superior holding force, neodymium magnets have these key benefits:
  • They have constant strength, and over around ten years their performance decreases symbolically – ~1% (in testing),
  • They are noted for resistance to demagnetization induced by presence of other magnetic fields,
  • The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to look better,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Thanks to flexibility in forming and the ability to modify to unusual requirements,
  • Wide application in advanced technology sectors – they serve a role in mass storage devices, electromotive mechanisms, diagnostic systems, and multitasking production systems.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:
  • At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
  • We recommend a housing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex shapes.
  • Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small elements of these magnets can disrupt the diagnostic process medical in case of swallowing.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Highest magnetic holding forcewhat it depends on?

The force parameter is a theoretical maximum value performed under standard conditions:
  • using a base made of high-permeability steel, acting as a magnetic yoke
  • whose transverse dimension is min. 10 mm
  • with a plane cleaned and smooth
  • with direct contact (no coatings)
  • for force acting at a right angle (pull-off, not shear)
  • in temp. approx. 20°C

Key elements affecting lifting force

During everyday use, the actual lifting capacity depends on a number of factors, ranked from most significant:
  • Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
  • Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Chemical composition of the base – mild steel attracts best. Higher carbon content decrease magnetic permeability and holding force.
  • Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
  • Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was assessed using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

Precautions when working with neodymium magnets
Risk of cracking

NdFeB magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets leads to them cracking into small pieces.

Magnetic media

Intense magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.

Precision electronics

Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Physical harm

Big blocks can break fingers in a fraction of a second. Never put your hand between two attracting surfaces.

Immense force

Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Operating temperature

Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Medical interference

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Nickel allergy

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease working with magnets and use protective gear.

Danger to the youngest

Absolutely store magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are fatal.

Combustion hazard

Dust produced during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
