Magnetic force decreases drastically with every mm of gap. Remember that every additional insulation layer (e.g., dirt, varnish, dust) noticeably weakens the grip. Magnets hold strongest during direct contact; distance weakens the power. Observe how rapidly the parameters fall, when the magnet does not adhere tightly to the steel surface. When planning the assembly, avoid redundant distances.

The table below defines the estimated shear load needed to start the sliding of the magnet vertically against a upright steel wall (assuming standard friction). This value varies with the air gap between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 8x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.39 kg / 0.86 lbs 390.0 g / 3.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.26 kg / 0.57 lbs 260.0 g / 2.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.13 kg / 0.29 lbs 130.0 g / 1.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.65 kg / 1.43 lbs 650.0 g / 6.4 N

When hanging a element on a vertical plane (e.g., a fridge), it you can count on barely approx. 20%-30% of its maximum pull force. Gravity and a low friction coefficient influence the fact that products slide down faster than they pull off. Want to create a wall mount? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will give way down under a significantly smaller cargo. Application of an anti-slip pad can significantly increase the grip.

2 mm	50%	0.65 kg / 1.43 lbs 650.0 g / 6.4 N
3 mm	75%	0.98 kg / 2.15 lbs 975.0 g / 9.6 N
5 mm	100%	1.30 kg / 2.87 lbs 1300.0 g / 12.8 N
10 mm	100%	1.30 kg / 2.87 lbs 1300.0 g / 12.8 N
11 mm	100%	1.30 kg / 2.87 lbs 1300.0 g / 12.8 N
12 mm	100%	1.30 kg / 2.87 lbs 1300.0 g / 12.8 N

A thin metal plate is not enough to focus the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this magnet's power, you require a sufficiently solid element of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the magnet works worse. We advise picking the steel cross-section from these parameters.

Standard neodymium magnets irreversibly lose parameters past the thermal threshold. Protect against heat – heat can irreversibly demagnetize this product. As the temperature rises, the neodymium's capacity momentarily decreases. Avoid using this magnet close to heaters exceeding its working range. Too high temperature will result in irreversible degradation of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) risk losing magnetic properties sooner compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a magnet and sheet combination. Such a system of two magnets produces a massive flux and a wider radius of performance. Designing a strong closure? Apply two magnets instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the pinch force is massive. The levitation is marginally weaker than the attraction, but still impressive.
*The magnetic induction in repulsion mode reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Figures refer to shear force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to IT equipment and pacemakers. These NdFeB products generate a field that prevents correct functioning of digital equipment. Remember: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (kinetic energy) - collision effects

100 mm	41.88 km/h (11.63 m/s)	0.51 J

NdFeB products are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or painful pinches to fingers. Be sure to control the product during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when handling with powerful specimens.

Corrosion 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. Sliding resistance

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

2. Plate thickness effect

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

3. Heat tolerance

*For N38 material, the critical limit 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.

This product is a very strong cylindrical magnet, composed of modern NdFeB material, which, with dimensions of Ø8x20 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 1.30 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the high power of 12.71 N with a weight of only 7.54 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø8x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 8 mm and height 20 mm. The key parameter here is the holding force amounting to approximately 1.30 kg (force ~12.71 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 20 mm), which means that the N and S poles are located on the flat, circular surfaces. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized diametrically if your project requires it.

Pros and cons of rare earth magnets.

Strengths

Besides their remarkable strength, neodymium magnets offer the following advantages:

They retain magnetic properties for nearly ten years – the drop is just ~1% (according to analyses),
They possess excellent resistance to magnetism drop as a result of external fields,
In other words, due to the metallic layer of gold, the element looks attractive,
Neodymium magnets deliver maximum magnetic induction on a their surface, which ensures high operational effectiveness,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Thanks to flexibility in designing and the capacity to adapt to unusual requirements,
Fundamental importance in high-tech industry – they are commonly used in HDD drives, brushless drives, precision medical tools, also industrial machines.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems

Limitations

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited ability of producing nuts in the magnet and complicated forms - recommended is casing - mounting mechanism.
Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what it depends on?

Holding force of 1.30 kg is a measurement result performed under standard conditions:

on a base made of mild steel, perfectly concentrating the magnetic flux
whose transverse dimension reaches at least 10 mm
characterized by lack of roughness
under conditions of no distance (surface-to-surface)
during pulling in a direction vertical to the mounting surface
at temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

In practice, the actual lifting capacity results from a number of factors, listed from most significant:

Distance (between the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.

Precautions when working with NdFeB magnets

Permanent damage

Do not overheat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Fire risk

Powder created during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Handling guide

Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their power.

Nickel allergy

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

Keep away from computers

Device Safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).

Eye protection

Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

Swallowing risk

Absolutely keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are life-threatening.

Compass and GPS

A strong magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to avoid breaking the sensors.

ICD Warning

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

Hand protection

Large magnets can crush fingers in a fraction of a second. Do not place your hand between two strong magnets.
