1. Shear force

*Warning: On a vertical surface, the magnet retains merely ~20% of its nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Thermal stability

*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) = 0.29

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.

Other products

The offered product is an exceptionally strong cylinder magnet, composed of durable NdFeB material, which, with dimensions of Ø10x2 mm, guarantees the highest energy density. The MW 10x2 / N38 model boasts high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.27 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating shields 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 positioning or actuating element. Thanks to the high power of 12.50 N with a weight of only 1.18 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.
Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in automation, anaerobic resins 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 popular standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø10x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.
This model is characterized by dimensions Ø10x2 mm, which, at a weight of 1.18 g, makes it an element with high magnetic energy density. The value of 12.50 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.18 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 2 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 through the diameter if your project requires it.

Pros and cons of rare earth magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose magnetism, even during approximately 10 years – the decrease in lifting capacity is only ~1% (based on measurements),
  • They are extremely resistant to demagnetization induced by presence of other magnetic fields,
  • By using a decorative layer of silver, the element acquires an aesthetic look,
  • Magnets have extremely high magnetic induction on the surface,
  • Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
  • Possibility of precise machining as well as adjusting to precise applications,
  • Universal use in advanced technology sectors – they serve a role in magnetic memories, drive modules, medical equipment, also other advanced devices.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Cons of neodymium magnets: weaknesses and usage proposals
  • They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
  • Neodymium magnets lose 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
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • Due to limitations in creating threads and complex shapes in magnets, we recommend using casing - magnetic mechanism.
  • Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
  • With mass production the cost of neodymium magnets is economically unviable,

Pull force analysis

Optimal lifting capacity of a neodymium magnetwhat affects it?

Breakaway force was determined for the most favorable conditions, assuming:
  • on a base made of structural steel, effectively closing the magnetic field
  • possessing a massiveness of at least 10 mm to ensure full flux closure
  • with a plane cleaned and smooth
  • without the slightest clearance between the magnet and steel
  • for force applied at a right angle (in the magnet axis)
  • at standard ambient temperature

Lifting capacity in practice – influencing factors

In practice, the actual lifting capacity is determined by several key aspects, listed from most significant:
  • Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Load vector – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
  • Surface quality – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
  • Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.

Safety rules for work with NdFeB magnets
Swallowing risk

Adult use only. Small elements can be swallowed, causing severe trauma. Keep away from kids and pets.

Protect data

Data protection: Neodymium magnets can damage payment cards and delicate electronics (heart implants, hearing aids, timepieces).

Medical implants

Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.

Threat to navigation

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

Warning for allergy sufferers

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness happens, cease handling magnets and use protective gear.

Caution required

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

Bodily injuries

Large magnets can smash fingers in a fraction of a second. Never place your hand between two strong magnets.

Dust is flammable

Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

Heat warning

Avoid heat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Fragile material

Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
