Grip strength decreases sharply per each millimeter of spacing. Note that even a very thin break (e.g., dirt, varnish, veneer) strongly diminishes the holding power. Magnets work strongest in perfect adhesion; distance drastically cuts the power. Observe how rapidly the pull force drop, when the product does not adhere tightly to the metal substrate. When designing the arrangement, discard unnecessary gaps.

When placing a magnet on a upright surface (e.g., a board), it you can count on barely approx. 20%-30% of its maximum pull force. Gravity and a weak degree of grip mean that products move down easier than they pop off the substrate. Designing a hanger? Remember that the shear force is significantly lower than the maximum static pull force. On a painted metal, the holder will slide down under a much lighter cargo. Using a rubber pad can effectively raise the stability.

A thin metal plate is unable to focus the entire magnetic field, which weakens actual performance of the magnet. Should you attach a powerful product to a too thin substrate, the magnetism will pass right through and the holding will be smaller. To achieve full efficiency of this magnet's potential, you require a sufficiently solid element of metal. The saturation phenomenon means that on thin elements (e.g., appliance housings), the product shows lower pull force. We recommend selecting the steel cross-section based on the following data.

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Watch out for overheating – heat can irreversibly destroy this product. With every degree above norm, the neodymium's power briefly drops. Do not use this product in hot environments higher than its operating temperature limit. Too high temperature will lead to destruction of magnetic properties.
*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a wider radius than a magnet and sheet setup. The connection of magnet-to-magnet generates a stronger field and a further horizon of operation. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is huge. The repulsion force is a bit weaker than the attraction, but still large.
*Flux density in repulsion mode is approximately ~0 Gs at the geometric center of the gap (due to field cancellation).
Attention: Results refer to friction force of two matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to electronic devices and pacemakers. These NdFeB products generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation passes through tissues and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

NdFeB products are prone to chipping – a violent impact against metal risks their cracking. Control the attraction moment – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.
1. Vertical hold

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

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Heat tolerance

*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) = 0.45

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 a very strong cylinder magnet, produced from durable NdFeB material, which, at dimensions of Ø28.9x10 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 20.74 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 203.46 N with a weight of only 49.2 g, this rod is indispensable in electronics 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 immediate cracking of this professional component. To ensure stability 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 suitable for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø28.9x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 28.9 mm and height 10 mm. The value of 203.46 N means that the magnet is capable of holding a weight many times exceeding its own mass of 49.2 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, 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 28.9 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 diametrically if your project requires it.

Strengths and weaknesses of Nd2Fe14B magnets.

Strengths

Besides their remarkable pulling force, neodymium magnets offer the following advantages:
  • They do not lose power, even after approximately 10 years – the drop in strength is only ~1% (according to tests),
  • They have excellent resistance to magnetism drop as a result of external fields,
  • By covering with a smooth layer of gold, the element gains an aesthetic look,
  • Magnets are distinguished by exceptionally strong magnetic induction on the outer layer,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Considering the possibility of free shaping and customization to custom solutions, magnetic components can be created in a wide range of forms and dimensions, which amplifies use scope,
  • Key role in electronics industry – they serve a role in hard drives, electric motors, medical devices, and industrial machines.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Problematic aspects of neodymium magnets: weaknesses and usage proposals
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
  • NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as 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
  • When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
  • We recommend a housing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
  • Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
  • Due to expensive raw materials, their price exceeds standard values,

Holding force characteristics

Maximum magnetic pulling force – what affects it?

The load parameter shown refers to the limit force, measured under optimal environment, namely:
  • with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
  • whose transverse dimension reaches at least 10 mm
  • characterized by lack of roughness
  • without any insulating layer between the magnet and steel
  • during pulling in a direction vertical to the mounting surface
  • at temperature room level

Practical lifting capacity: influencing factors

Please note that the application force may be lower influenced by elements below, starting with the most relevant:
  • Distance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
  • Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Base massiveness – too thin sheet does not close the flux, causing part of the flux to be wasted to the other side.
  • Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
  • Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
  • Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Warnings
No play value

NdFeB magnets are not intended for children. Swallowing a few magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.

Heat warning

Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Protective goggles

Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.

Crushing risk

Risk of injury: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.

Health Danger

For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.

Magnetic interference

Note: rare earth magnets produce a field that interferes with precision electronics. Maintain a separation from your mobile, tablet, and GPS.

Electronic devices

Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.

Allergy Warning

Nickel alert: The nickel-copper-nickel coating contains nickel. If redness happens, immediately stop working with magnets and use protective gear.

Handling rules

Handle magnets with awareness. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their force.

Fire risk

Machining of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
