Magnetic force drops significantly with every mm of distance. Remember that even a very thin break (e.g., contamination, varnish, veneer) noticeably reduces the pull force. Neodymiums operate most effectively at the point of direct contact; distance kills the power. See how quickly the parameters drop, when the magnet does not touch directly to the steel surface. When planning the assembly, avoid unnecessary gaps.

The following data indicates the theoretical shear load required to initiate the sliding of the magnet vertically against a upright steel wall (assuming standard friction coefficient). This value is relative to the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	49.18 kg / 108.42 lbs 49179.0 g / 482.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	32.79 kg / 72.28 lbs 32786.0 g / 321.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	16.39 kg / 36.14 lbs 16393.0 g / 160.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	81.97 kg / 180.70 lbs 81965.0 g / 804.1 N

When mounting a element on a upright wall (e.g., a car body), it will only hold only approx. 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip mean that magnets slip faster than they pop off the substrate. Designing a vertical fastening? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the element will give way down under a much lighter load. Utilizing a rubberized pad can effectively improve the result.

A thin sheet is not enough to absorb the full magnetic flux, which wastes potential of the magnet. If you install a neodymium to a weak sheet, the magnetism will pass right through and the holding will be smaller. To achieve 100% of this neodymium's power, you require a sufficiently solid backing of steel. The saturation effect means that on thin elements (e.g., car bodies), the magnet shows lower pull force. We advise picking the steel dimension according to the table below.

Classic neodymiums irreversibly lose strength above the temperature limit. Avoid high temperatures – excessive heat can irreversibly demagnetize this magnet. With every degree above norm, the neodymium's power briefly drops. Avoid using this product close to ovens higher than its operating temperature limit. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) are more susceptible to demagnetization at lower temperatures than long magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnets interact from a wider radius than a neodymium and metal combination. Such a system of two magnets creates a more powerful interaction and a wider radius of action. Planning to create a strong closure? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is extreme. The levitation is marginally weaker than the connection force, but still significant.
*Flux density in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
* Figures show sliding force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to IT equipment as well as pacemakers. These NdFeB products produce a flux that disrupts operation of digital equipment. Remember: the unseen radiation acts through matter and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

100 mm	31.06 km/h (8.63 m/s)	64.44 J

Neodymium magnets are delicate – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or dangerous crushing to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when handling with powerful specimens.

Rust risk: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

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

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Power loss vs temp

*For N38 grade, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.82

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.

This product is a very strong cylindrical magnet, composed of advanced NdFeB material, which, with dimensions of Ø70x60 mm, guarantees the highest energy density. The MW 70x60 / N38 component features an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 163.93 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 1608.16 N with a weight of only 1731.8 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

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 precision component. To ensure stability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are suitable for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø70x60), 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 Ø70x60 mm, which, at a weight of 1731.8 g, makes it an element with high magnetic energy density. The value of 1608.16 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1731.8 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 60 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 diametrically if your project requires it.

Pros and cons of rare earth magnets.

Benefits

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

Their magnetic field is maintained, and after approximately 10 years it decreases only by ~1% (according to research),
Neodymium magnets are exceptionally resistant to magnetic field loss caused by external field sources,
In other words, due to the aesthetic layer of nickel, the element is aesthetically pleasing,
Neodymium magnets achieve maximum magnetic induction on a their surface, 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...
Possibility of accurate creating as well as adapting to individual conditions,
Fundamental importance in future technologies – they are commonly used in HDD drives, electric motors, medical devices, and industrial machines.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Weaknesses

Characteristics of disadvantages of neodymium magnets and proposals for their use:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves 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 start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
Limited ability of making nuts in the magnet and complex shapes - preferred is cover - magnetic holder.
Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Maximum lifting capacity of the magnet – what contributes to it?

Information about lifting capacity was defined for ideal contact conditions, taking into account:

using a sheet made of high-permeability steel, serving as a circuit closing element
possessing a massiveness of at least 10 mm to avoid saturation
with an ground contact surface
without the slightest insulating layer between the magnet and steel
for force applied at a right angle (pull-off, not shear)
in stable room temperature

Lifting capacity in real conditions – factors

During everyday use, the real power results from several key aspects, ranked from most significant:

Air gap (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
Steel thickness – insufficiently thick plate does not close the flux, causing part of the flux to be wasted to the other side.
Plate material – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and holding force.
Smoothness – full contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Temperature – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.

H&S for magnets

Eye protection

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets leads to them breaking into shards.

Fire warning

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

Serious injuries

Risk of injury: The pulling power is so great that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.

Heat warning

Avoid heat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).

Threat to electronics

Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.

ICD Warning

Patients with a pacemaker should keep an safe separation from magnets. The magnetic field can disrupt the operation of the life-saving device.

Nickel allergy

Certain individuals have a sensitization to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to a rash. We suggest use safety gloves.

Danger to the youngest

Neodymium magnets are not intended for children. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.

Handling rules

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

GPS and phone interference

GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.
