Pulling power weakens drastically per each millimeter of spacing. Keep in mind that even a microscopic distance (e.g., contamination, paint, rust) strongly weakens the grip. Magnetic products operate most effectively during direct contact; air break weakens the force. Analyze how flashily the parameters plummet, when the product does not touch directly to the steel surface. When planning the mounting, avoid redundant distances.

This section defines the theoretical weight limit sufficient to cause the slippage of the magnet down against a vertical metal surface (assuming standard friction coefficient). This value varies with the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 12x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.75 kg / 1.65 LBS 747.0 g / 7.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.50 kg / 1.10 LBS 498.0 g / 4.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.25 kg / 0.55 LBS 249.0 g / 2.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.25 kg / 2.74 LBS 1245.0 g / 12.2 N

When placing a element on a vertical wall (e.g., a board), it you can count on barely about 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient mean that magnets slip easier than they pull off. Designing a wall mount? Note that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a noticeably lighter weight. Utilizing a rubberized layer can drastically increase the grip.

A too thin steel is not enough to absorb the entire magnetic field, which wastes potential of the magnet. Should you install a neodymium to a thin surface, the field will pass right through and the attraction force will be weaker. To squeeze 100% of this neodymium's power, you require a sufficiently solid piece of steel. The saturation effect causes that on sheet metal structures (e.g., thin profiles), the product works worse. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products lose parameters after exceeding the maximum temperature. Protect against heat – heat can permanently destroy this magnet. As the temperature rises, the magnet's capacity momentarily drops. Do not use this magnet near heat sources higher than its operating temperature limit. Exceeding the critical threshold will cause permanent loss of magnetism.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Flat magnets (pancake types) are more susceptible to demagnetization sooner compared to rod magnets. Red status in the table points to permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet setup. Such a system of magnet-to-magnet produces a massive flux and a further horizon of action. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the pinch force is huge. The repulsion force is slightly lower than the attraction, but still significant.
*Flux density in repulsion mode is approximately ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Attention: Estimates apply to friction force of dual identical magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to electronic devices as well as medical implants. These NdFeB products generate a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - warning

Magnetic elements are very brittle – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or injury to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when handling with powerful specimens.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Steel thickness impact

*Thin steel (e.g. computer case) severely weakens the holding force.

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.35

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 offered product is a very strong cylinder magnet, produced from advanced NdFeB material, which, at dimensions of Ø12x3 mm, guarantees optimal power. This specific item is characterized by a tolerance of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 2.49 kg), this product is in stock 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 finds application in DIY projects, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 24.43 N with a weight of only 2.54 g, this rod is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 12.1 mm) using epoxy glues. To ensure long-term durability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability 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 even stronger magnets in the same volume (Ø12x3), 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 Ø12x3 mm, which, at a weight of 2.54 g, makes it an element with high magnetic energy density. The value of 24.43 N means that the magnet is capable of holding a weight many times exceeding its own mass of 2.54 g. The product has a [NiCuNi] coating, which secures it 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 12 mm. Such an arrangement is standard 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 as well as weaknesses of neodymium magnets.

Benefits

Besides their stability, neodymium magnets are valued for these benefits:

They do not lose power, even during around ten years – the reduction in strength is only ~1% (based on measurements),
Magnets effectively protect themselves against demagnetization caused by foreign field sources,
The use of an refined layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnets are characterized by excellent magnetic induction on the outer side,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
Possibility of custom forming as well as adjusting to individual needs,
Fundamental importance in innovative solutions – they serve a role in hard drives, electric drive systems, diagnostic systems, and multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets decrease their power 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 stability even at temperatures up to 230°C
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
Limited ability of making threads in the magnet and complicated shapes - preferred is casing - mounting mechanism.
Health risk related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these products can complicate diagnosis medical when they are in the body.
With mass production the cost of neodymium magnets is a challenge,

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what affects it?

Magnet power was determined for the most favorable conditions, assuming:

on a block made of structural steel, effectively closing the magnetic field
whose transverse dimension equals approx. 10 mm
characterized by smoothness
without any insulating layer between the magnet and steel
during pulling in a direction perpendicular to the plane
at room temperature

Magnet lifting force in use – key factors

During everyday use, the actual lifting capacity is determined by several key aspects, presented from most significant:

Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Load vector – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

Safety rules for work with neodymium magnets

Product not for children

Only for adults. Small elements pose a choking risk, leading to severe trauma. Keep away from children and animals.

GPS and phone interference

A strong magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Keep magnets near a device to avoid breaking the sensors.

Magnetic media

Avoid bringing magnets close to a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.

Fragile material

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Implant safety

Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

Avoid contact if allergic

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, immediately stop handling magnets and wear gloves.

Maximum temperature

Monitor thermal conditions. Exposing the magnet to high heat will ruin its properties and strength.

Do not underestimate power

Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Flammability

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

Crushing force

Large magnets can smash fingers instantly. Do not put your hand betwixt two attracting surfaces.
