Grip strength weakens drastically per each millimeter of distance. Remember that even a very thin break (e.g., dirt, varnish, veneer) strongly diminishes the holding power. Magnetic products hold optimally in perfect adhesion; distance weakens the force. Notice how flashily the pull force plummet, when the magnet does not touch directly to the metal substrate. When designing the mounting, discard additional spacers.

This section presents the approximate holding capacity required to start the sliding of the magnet vertically along a vertical metal surface (considering standard friction). The holding force varies with the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 4x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.10 kg / 0.21 LBS 96.0 g / 0.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.06 kg / 0.14 LBS 64.0 g / 0.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.03 kg / 0.07 LBS 32.0 g / 0.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.16 kg / 0.35 LBS 160.0 g / 1.6 N

When placing a magnet on a vertical surface (e.g., a board), it you can count on barely approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip influence the fact that magnets slide down faster than they pull off. Planning a wall mount? Note that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a noticeably lighter load. Application of an anti-slip layer can significantly increase the grip.

12 mm	100%	0.32 kg / 0.71 LBS 320.0 g / 3.1 N

A thin sheet cannot take in the entire magnetic field, which weakens actual performance of the holder. If you install a neodymium to a weak sheet, the field will pass right through and the attraction force will be weaker. To achieve full efficiency of this magnet's power, you need a suitably thick piece of metal. The saturation phenomenon means that on thin elements (e.g., appliance housings), the product works worse. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products lose power past the thermal threshold. Watch out for overheating – heat can permanently demagnetize this product. As the temperature rises, the neodymium's capacity temporarily decreases. Do not use this magnet near heat sources exceeding its safe range. Exceeding the critical threshold will result in destruction of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) may lose charge permanently sooner than long magnets. Red status in the table indicates permanent field degradation for this particular item.

Two magnets attract each other from a wider radius than a magnet and sheet combination. The connection of magnet-to-magnet produces a massive flux and a further horizon of operation. Designing a strong closure? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the collision energy is extreme. The levitation is slightly lower than the connection force, but still impressive.
*Flux density for N-N configuration reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Attention: Calculations refer to friction force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to IT equipment and medical implants. These magnets produce a field that destroys function of sensitive medical devices. Notice: the unseen radiation passes through tissues and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are very brittle – a strong collision with metal can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can cause material chips or injury to skin. Always hold the magnet during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when playing with large magnets.

Corrosion 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. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet holds only a fraction of its perpendicular strength.

2. Plate thickness effect

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

3. Heat tolerance

*For standard magnets, 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) = 1.31

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 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 cylindrical magnet, produced from advanced NdFeB material, which, at dimensions of Ø4x10 mm, guarantees the highest energy density. This specific item is characterized by high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.32 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 3.16 N with a weight of only 0.94 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

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., 4.1 mm) using two-component epoxy glues. To ensure stability 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 popular standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø4x10), 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 Ø4x10 mm, which, at a weight of 0.94 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 0.32 kg (force ~3.16 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it 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 4 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 as well as disadvantages of Nd₂Fe₁₄B magnets.

Strengths

In addition to their pulling strength, neodymium magnets provide the following advantages:

They retain attractive force for around ten years – the loss is just ~1% (in theory),
They are extremely resistant to demagnetization induced by external field influence,
In other words, due to the shiny finish of silver, the element looks attractive,
Neodymium magnets deliver maximum magnetic induction on a contact point, which increases force concentration,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Considering the potential of accurate shaping and adaptation to custom requirements, neodymium magnets can be produced in a variety of forms and dimensions, which increases their versatility,
Fundamental importance in electronics industry – they are used in hard drives, motor assemblies, advanced medical instruments, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in small systems

Limitations

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
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
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating nuts and complex shapes in magnets, we recommend using cover - magnetic mount.
Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these products are able to be problematic in diagnostics medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what it depends on?

Breakaway force is the result of a measurement for optimal configuration, assuming:

on a block made of structural steel, perfectly concentrating the magnetic field
whose transverse dimension is min. 10 mm
characterized by smoothness
under conditions of ideal adhesion (surface-to-surface)
under perpendicular force vector (90-degree angle)
at ambient temperature room level

Lifting capacity in practice – influencing factors

Real force is influenced by specific conditions, mainly (from most important):

Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Steel thickness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be wasted to the other side.
Plate material – mild steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the holding force.

Precautions when working with neodymium magnets

Dust is flammable

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

Magnetic media

Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.

GPS and phone interference

Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.

Medical interference

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Magnets are brittle

Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

This is not a toy

Always keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.

Do not underestimate power

Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their force.

Crushing force

Large magnets can smash fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.

Warning for allergy sufferers

A percentage of the population experience a contact allergy to nickel, which is the common plating for NdFeB magnets. Prolonged contact might lead to a rash. We recommend use safety gloves.

Heat sensitivity

Keep cool. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
