Grip strength drops significantly per each millimeter of spacing. Note that even a very thin break (e.g., dirt, paint, dust) significantly diminishes the holding power. Magnetic products operate strongest at the point of direct contact; air break nullifies the power. Observe how rapidly the parameters plummet, when the product does not adhere tightly to the steel surface. When planning the mounting, avoid additional spacers.

The following data calculates the estimated weight limit required to start the downward movement of the magnet vertically against a upright steel wall (considering standard friction coefficient). This parameter is relative to the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 21.9x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	4.40 kg / 9.69 LBS 4395.0 g / 43.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.93 kg / 6.46 LBS 2930.0 g / 28.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.47 kg / 3.23 LBS 1465.0 g / 14.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	7.33 kg / 16.15 LBS 7325.0 g / 71.9 N

When mounting a element on a upright plane (e.g., a board), it you can count on just approx. 1/5 of its maximum pull force. Gravity and a low friction coefficient influence the fact that holders slip easier than they pop off the substrate. Designing a wall mount? Note that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a significantly smaller cargo. Using a rubber coating can significantly improve the result.

A too thin steel cannot conduct the full magnetic flux, which wastes potential of the magnet. If you install a neodymium to a too thin substrate, the field will pass right through and the pull force will drop sharply. To achieve full efficiency of this magnet's potential, you require a sufficiently solid backing of steel. The saturation effect means that on thin elements (e.g., thin profiles), the magnet holds weaker. We suggest choosing the steel cross-section according to the table below.

Classic neodymiums change their properties strength after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly demagnetize this product. With increasing heat, the neodymium's force briefly decreases. Avoid using this product in hot environments higher than its safe range. Too high temperature will cause destruction of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) are more susceptible to demagnetization sooner than taller cylinders. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a magnet and sheet combination. Such a system of two magnets creates a more powerful interaction and a wider radius of performance. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the impact force is massive. The levitation is marginally weaker than the attraction, but still large.
*Field value for N-N configuration reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Attention: Figures show sliding force of two matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field poses a large risk to electronic devices and pacemakers. These neodymiums produce a flux that destroys function of digital equipment. Notice: the invisible magnetic field acts through matter and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (cracking risk) - collision effects
MW 21.9x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	24.23 km/h (6.73 m/s)	0.64 J

50 mm	51.36 km/h (14.27 m/s)	2.87 J
100 mm	72.63 km/h (20.17 m/s)	5.75 J

Neodymium magnets are very brittle – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Impact energy can cause material chips or painful pinches to fingers. 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 means shattering of the magnet. 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.

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Vertical hold

*Caution: On a vertical wall, the magnet holds merely ~20% of its max power.

2. Steel saturation

*Thin metal sheet (e.g. computer case) drastically reduces the holding force.

3. Power loss vs temp

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.55

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 P_c (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 P_c 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, at dimensions of Ø21.9x10 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 14.65 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 143.71 N with a weight of only 28.25 g, this cylindrical magnet is indispensable in electronics 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 chipping the coating of this professional component. To ensure stability in automation, anaerobic resins 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 the strongest magnets in the same volume (Ø21.9x10), 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 21.9 mm and height 10 mm. The key parameter here is the lifting capacity amounting to approximately 14.65 kg (force ~143.71 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 10 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.

Strengths and weaknesses of neodymium magnets.

Strengths

In addition to their long-term stability, neodymium magnets provide the following advantages:

They retain magnetic properties for almost ten years – the loss is just ~1% (based on simulations),
They maintain their magnetic properties even under strong external field,
A magnet with a metallic silver surface has better aesthetics,
Magnets have exceptionally strong magnetic induction on the surface,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
Thanks to freedom in designing and the ability to modify to unusual requirements,
Fundamental importance in high-tech industry – they are utilized in hard drives, brushless drives, medical equipment, and complex engineering applications.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 extremely resistant to heat
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of making nuts in the magnet and complicated forms - preferred is cover - magnetic holder.
Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting capacity of the magnet – what affects it?

The force parameter is a theoretical maximum value performed under the following configuration:

with the use of a yoke made of special test steel, ensuring full magnetic saturation
whose thickness reaches at least 10 mm
with a surface cleaned and smooth
with zero gap (without paint)
during pulling in a direction perpendicular to the mounting surface
at ambient temperature room level

Key elements affecting lifting force

It is worth knowing that the application force may be lower subject to the following factors, in order of importance:

Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Plate thickness – too thin steel does not close the flux, causing part of the power to be escaped into the air.
Material composition – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate decreases the load capacity.

Precautions when working with neodymium magnets

Crushing risk

Big blocks can crush fingers instantly. Never put your hand between two attracting surfaces.

Operating temperature

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Handling guide

Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Pacemakers

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Danger to the youngest

NdFeB magnets are not intended for children. Accidental ingestion of a few magnets can lead to them attracting across intestines, which poses a critical condition and requires immediate surgery.

Dust is flammable

Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Beware of splinters

Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Safe distance

Intense magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.

Nickel coating and allergies

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.

Precision electronics

An intense magnetic field disrupts the functioning of compasses in phones and navigation systems. Do not bring magnets near a device to avoid damaging the sensors.
