Magnetic force weakens sharply with every mm of spacing. Remember that even a microscopic distance (e.g., contamination, varnish, dust) noticeably weakens the grip. Magnetic products operate most effectively during direct contact; distance kills the force. Notice how rapidly the load capacity drop, when the product does not adhere flatly to the steel surface. When planning the assembly, eliminate redundant distances.

The table below calculates the approximate force necessary to initiate the downward movement of the magnet vertically on a vertical metal surface (assuming typical friction coefficient). This value varies with the air gap between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 18.9x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.50 kg / 3504.0 g 34.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.34 kg / 2336.0 g 22.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.17 kg / 1168.0 g 11.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.84 kg / 5840.0 g 57.3 N

When hanging a magnet on a vertical surface (e.g., a fridge), it you can count on just about 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip cause that products move down easier than they detach. Want to create a hanger? Remember that the shear force is significantly lower than the maximum static pull force. On a painted metal, the magnet will give way down under a much lighter weight. Application of an anti-slip layer can significantly raise the stability.

Table 4: Material efficiency (saturation) - power losses

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	5%	0.58 kg / 584.0 g 5.7 N

10 mm	100%	11.68 kg / 11680.0 g 114.6 N

A too thin steel is unable to conduct the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a thin surface, the flux will penetrate right through and the holding will be smaller. To squeeze 100% of this magnet's power, you need a suitably thick piece of metal. The material oversaturation means that on delicate walls (e.g., car bodies), the product shows lower pull force. We recommend selecting the steel dimension according to the table below.

100 °C	-28.8%	8.32 kg / 8316.2 g 81.6 N

Ordinary NdFeB products irreversibly lose strength after exceeding the maximum temperature. Watch out for overheating – heat can permanently demagnetize this product. With every degree above norm, the magnet's force briefly decreases. Refrain from using this magnet in hot environments exceeding its operating temperature limit. Ignoring the limit will result in permanent loss of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) risk losing magnetic properties under lower heat stress than long magnets. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and sheet setup. Such a system of two magnets produces a massive flux and a wider radius of performance. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the impact force is extreme. The levitation is a bit weaker than the attraction, but still significant.
*The magnetic induction for N-N configuration reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).

Extremely neodym field poses a serious hazard to electronics and medical implants. These magnets generate a flux that disrupts operation of digital equipment. Notice: the unseen radiation acts through matter and plastic. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MW 18.9x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	24.63 km/h (6.84 m/s)	0.49 J
30 mm	41.18 km/h (11.44 m/s)	1.38 J
50 mm	53.13 km/h (14.76 m/s)	2.29 J
100 mm	75.14 km/h (20.87 m/s)	4.58 J

Magnetic elements are delicate – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Kinetic force can trigger coating fragments or injury to fingers. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when handling with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Note: On a vertical surface, the magnet retains only approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) severely reduces the holding force.

3. Thermal stability

*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) = 0.61

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 an extremely powerful rod magnet, produced from modern NdFeB material, which, with dimensions of Ø18.9x10 mm, guarantees optimal power. The MW 18.9x10 / N38 component is characterized by a tolerance of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 11.68 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 114.54 N with a weight of only 21.04 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure stability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are strong enough for the majority 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 (Ø18.9x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø18.9x10 mm, which, at a weight of 21.04 g, makes it an element with impressive magnetic energy density. The value of 114.54 N means that the magnet is capable of holding a weight many times exceeding its own mass of 21.04 g. 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 18.9 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 through the diameter if your project requires it.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

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

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
They maintain their magnetic properties even under close interference source,
A magnet with a smooth nickel surface has an effective appearance,
Magnetic induction on the working layer of the magnet turns out to be maximum,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of detailed modeling and adjusting to individual applications,
Key role in innovative solutions – they find application in mass storage devices, electromotive mechanisms, diagnostic systems, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in miniature devices

Weaknesses

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited ability of making threads in the magnet and complicated forms - preferred is a housing - magnet mounting.
Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Maximum holding power of the magnet – what contributes to it?

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

with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
with a thickness minimum 10 mm
characterized by even structure
with zero gap (without impurities)
under axial application of breakaway force (90-degree angle)
at temperature room level

Lifting capacity in real conditions – factors

It is worth knowing that the application force may be lower depending on elements below, in order of importance:

Distance – existence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Steel type – low-carbon steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Warnings

Handling rules

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.

Fire risk

Machining of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Precision electronics

Remember: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, tablet, and navigation systems.

Magnets are brittle

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

Data carriers

Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.

Medical implants

Individuals with a ICD have to maintain an safe separation from magnets. The magnetism can interfere with the functioning of the implant.

Bone fractures

Big blocks can crush fingers instantly. Do not place your hand between two attracting surfaces.

Demagnetization risk

Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.

This is not a toy

Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Keep out of reach of children and animals.

Allergic reactions

It is widely known that nickel (the usual finish) is a strong allergen. For allergy sufferers, prevent direct skin contact or choose encased magnets.
