1. Sliding resistance

*Caution: On a vertical wall, the magnet retains just approx. 20-30% of its max power.

2. Steel saturation

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.71

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 extremely powerful cylindrical magnet, composed of modern NdFeB material, which, with dimensions of Ø15x10 mm, guarantees optimal power. This specific item boasts high dimensional repeatability and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 7.70 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is perfect for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 75.55 N with a weight of only 13.25 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
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 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 industrial neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø15x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 15 mm and height 10 mm. The key parameter here is the lifting capacity amounting to approximately 7.70 kg (force ~75.55 N), which, with such compact 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 15 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 and disadvantages of neodymium magnets.

Advantages

Apart from their superior power, neodymium magnets have these key benefits:
  • They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
  • They possess excellent resistance to magnetism drop due to external magnetic sources,
  • The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
  • Thanks to versatility in shaping and the capacity to modify to unusual requirements,
  • Key role in high-tech industry – they are used in HDD drives, drive modules, medical equipment, and modern systems.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Problematic aspects of neodymium magnets: tips and applications.
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
  • We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
  • We suggest a housing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated shapes.
  • Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can complicate diagnosis medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Highest magnetic holding forcewhat affects it?

The force parameter is a theoretical maximum value performed under standard conditions:
  • with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
  • possessing a thickness of minimum 10 mm to ensure full flux closure
  • characterized by even structure
  • with total lack of distance (no coatings)
  • for force applied at a right angle (in the magnet axis)
  • at standard ambient temperature

Magnet lifting force in use – key factors

Holding efficiency impacted by working environment parameters, such as (from priority):
  • Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Angle of force application – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
  • Steel grade – the best choice is high-permeability steel. Stainless steels may attract less.
  • Surface quality – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
  • Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets
ICD Warning

People with a pacemaker should maintain an safe separation from magnets. The magnetism can stop the functioning of the implant.

Electronic devices

Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can destroy these devices and erase data from cards.

Danger to the youngest

Always store magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are tragic.

Hand protection

Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Impact on smartphones

A powerful magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to avoid damaging the sensors.

Skin irritation risks

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

Do not underestimate power

Use magnets consciously. Their huge power can shock even experienced users. Be vigilant and do not underestimate their power.

Eye protection

NdFeB magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them shattering into small pieces.

Do not overheat magnets

Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. This process is irreversible.

Combustion hazard

Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Attention! More info about hazards in the article: Magnet Safety Guide.
