Frequently asked questions

What is the maximum working temperature of a disc magnet?
Standard N-series grades work up to 80 °C. Grades N50, N52 and N54 have a lower limit of 60 °C, because coercivity falls as BHmax rises. Higher temperatures require the H (120 °C), SH (150 °C), UH (180 °C), EH (200 °C) or AH (230 °C) series. Within the working range the magnet loses about 0.11% of its induction per degree, and that loss is reversible.
What is the difference between N38, N42 and N52?
The number after N is the energy product BHmax. Moving from N38 to N52 raises it by several tens of percent, but the real holding force increases by roughly 20%, because force also depends on geometry and on the magnetic circuit. N52 costs about twice as much as N42, so for most mounting work N38–N42 is the best price-to-force ratio.
What is the dimensional tolerance?
±0.1 mm as standard, ±0.05 mm to order. The tolerance is stated next to the dimensions on every product page.

Magnetic force drops sharply with every mm of gap. Keep in mind that even the smallest gap (e.g., contamination, paint, rust) strongly reduces the pull force. Magnets operate optimally at the point of direct contact; air break nullifies the power. Analyze how rapidly the parameters plummet, when the magnet does not touch directly to the metal substrate. When calculating the arrangement, discard redundant distances.

The following data presents the theoretical holding capacity necessary to initiate the slippage of the magnet vertically along a upright steel plate (considering standard friction). This parameter is a function of the gap size between the magnet and the surface.

When hanging a holder on a upright surface (e.g., a fridge), it will only hold only about 20%-30% of its nominal power. Gravity as well as a weak degree of grip influence the fact that magnets slip faster than they pop off the substrate. Want to create a wall mount? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a much lighter cargo. Application of an anti-slip layer can significantly raise the stability.

A too thin steel is not enough to absorb the full magnetic flux, which squanders power of the holder. If you mount a strong magnet to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To achieve the maximum of this neodymium's potential, you require a sufficiently solid element of steel. The saturation phenomenon means that on thin elements (e.g., car bodies), the product works worse. We advise picking the steel cross-section based on the following data.

Classic neodymiums lose parameters after exceeding the maximum temperature. Protect against heat – excessive heat can irreversibly damage this magnet. With increasing heat, the magnet's power momentarily decreases. Avoid using this magnet close to heaters higher than its safe range. Ignoring the limit will result in destruction of magnetic properties.
*Engineering note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) risk losing magnetic properties sooner than long magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal setup. The connection of magnet-to-magnet generates a stronger field and a further horizon of performance. Planning to create a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is massive. The levitation is slightly lower than the connection force, but still impressive.
*Field value between like poles reaches ~0 Gs at the geometric center between the magnets (due to field cancellation).
Important: Figures demonstrate shear force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a serious hazard to electronic devices as well as medical implants. These neodymiums produce a flux that disrupts operation of digital equipment. Remember: the invisible magnetic field acts through matter and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are prone to chipping – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Striking energy can cause material chips or dangerous crushing to fingers. Be sure to control the product during installation so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with large magnets.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!
Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

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

2. Efficiency vs thickness

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

3. Thermal stability

*For N38 material, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.59

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 offered product is an incredibly powerful rod magnet, produced from durable NdFeB material, which, with dimensions of Ø5x30 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.45 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 4.40 N with a weight of only 4.42 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Magnets NdFeB grade N38 are strong enough for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø5x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
This model is characterized by dimensions Ø5x30 mm, which, at a weight of 4.42 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 0.45 kg (force ~4.40 N), which, with such defined dimensions, proves the high power 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 5 mm. Such an arrangement is most desirable when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized diametrically if your project requires it.

Advantages as well as disadvantages of neodymium magnets.

Pros

Besides their stability, neodymium magnets are valued for these benefits:
  • They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
  • They are resistant to demagnetization induced by external magnetic fields,
  • By using a decorative coating of silver, the element acquires an nice look,
  • Neodymium magnets generate maximum magnetic induction on a small area, which increases force concentration,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • Possibility of custom machining and adjusting to precise conditions,
  • Huge importance in future technologies – they are used in HDD drives, electric drive systems, medical equipment, also modern systems.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Cons of neodymium magnets: tips and applications.
  • To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
  • Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Limited ability of producing nuts in the magnet and complicated forms - recommended is a housing - mounting mechanism.
  • Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small elements of these devices can complicate diagnosis medical after entering the body.
  • With budget limitations the cost of neodymium magnets is economically unviable,

Holding force characteristics

Best holding force of the magnet in ideal parameters – what contributes to it?

The lifting capacity listed is a result of laboratory testing conducted under the following configuration:
  • with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
  • whose transverse dimension is min. 10 mm
  • with an ideally smooth touching surface
  • with direct contact (without impurities)
  • under axial force vector (90-degree angle)
  • at standard ambient temperature

Determinants of practical lifting force of a magnet

Holding efficiency is affected by working environment parameters, including (from priority):
  • Distance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
  • Base massiveness – too thin plate does not close the flux, causing part of the power to be wasted into the air.
  • Material composition – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
  • Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
  • Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Precautions when working with NdFeB magnets
Powerful field

Handle with care. Neodymium magnets attract from a distance and snap with massive power, often faster than you can react.

Keep away from electronics

Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, device, and navigation systems.

Nickel allergy

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop working with magnets and use protective gear.

Bone fractures

Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!

Do not drill into magnets

Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.

Magnet fragility

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.

Safe distance

Intense magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.

No play value

These products are not toys. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which poses a critical condition and requires immediate surgery.

Danger to pacemakers

Patients with a heart stimulator must keep an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.

Do not overheat magnets

Do not overheat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
