Grip strength weakens drastically with every subsequent millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, rust) significantly weakens the grip. Magnets work optimally at the point of direct contact; gap weakens the force. See how flashily the pull force plummet, when the product does not adhere tightly to the metal substrate. When designing the arrangement, avoid redundant distances.

The following data shows the estimated weight limit required to initiate the sliding of the magnet down on a upright metal surface (considering typical friction). This parameter varies with the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 28.9x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	6.22 kg / 13.72 lbs 6222.0 g / 61.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.15 kg / 9.14 lbs 4148.0 g / 40.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.07 kg / 4.57 lbs 2074.0 g / 20.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	10.37 kg / 22.86 lbs 10370.0 g / 101.7 N

When placing a magnet on a vertical surface (e.g., a fridge), it will only hold barely about 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip mean that magnets slide down easier than they detach. Want to create a wall mount? Note that the shear force is significantly lower than the maximum static pull force. On a painted metal, the element will give way down under a much lighter weight. Using a rubber layer can significantly increase the grip.

A thin sheet is incapable of absorb the entire magnetic field, which weakens actual performance of the holder. If you mount a strong magnet to a weak sheet, the magnetism will pass right through and the pull force will drop sharply. To squeeze 100% of this neodymium's power, you need a suitably thick element of metal. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the holder shows lower pull force. We suggest choosing the steel dimension according to the table below.

Classic neodymiums lose strength after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently demagnetize this product. As the temperature rises, the magnet's power momentarily drops. Refrain from using this product close to heaters higher than its working range. Too high temperature will result in irreversible degradation of magnetism.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (pancake types) may lose charge permanently sooner than long magnets. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two magnetic products attract each other from a much further distance than a neodymium and metal combination. The setup of two magnets creates a more powerful interaction and a further horizon of performance. Designing a strong closure? Use a pair of magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the impact force is massive. The repulsion force is marginally weaker than the connection force, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center between the magnets (due to field cancellation).
Attention: Estimates refer to shear force of a pair of same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - precautionary measures

Powerful magnet radiation poses a large risk to electronic devices as well as pacemakers. These neodymiums produce a field that prevents correct functioning of sensitive medical devices. Remember: the unseen radiation passes through tissues and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - collision effects
MW 28.9x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	22.92 km/h (6.37 m/s)	1.00 J
30 mm	35.97 km/h (9.99 m/s)	2.46 J
50 mm	46.31 km/h (12.86 m/s)	4.07 J
100 mm	65.48 km/h (18.19 m/s)	8.14 J

NdFeB products 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. Impact energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when handling with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Sliding resistance

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

2. Plate thickness effect

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.45

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 an incredibly powerful rod magnet, composed of advanced NdFeB material, which, at dimensions of Ø28.9x10 mm, guarantees maximum efficiency. The MW 28.9x10 / N38 model is characterized by an accuracy of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 20.74 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields 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 203.46 N with a weight of only 49.2 g, this rod 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., 28.9.1 mm) using epoxy glues. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets N38 are suitable 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 (Ø28.9x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø28.9x10 mm, which, at a weight of 49.2 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 20.74 kg (force ~203.46 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 10 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 through the diameter if your project requires it.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Benefits

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

They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
Magnets perfectly resist against demagnetization caused by foreign field sources,
The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to the option of accurate shaping and adaptation to specialized projects, neodymium magnets can be modeled in a broad palette of shapes and sizes, which expands the range of possible applications,
Significant place in modern industrial fields – they are utilized in mass storage devices, electromotive mechanisms, diagnostic systems, as well as industrial machines.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Cons

What to avoid - cons of neodymium magnets and proposals for their use:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
Neodymium magnets lose their strength 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
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
We suggest a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated shapes.
Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Additionally, tiny parts of these magnets can complicate diagnosis medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Lifting parameters

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

The force parameter is a result of laboratory testing conducted under the following configuration:

with the application of a yoke made of special test steel, ensuring maximum field concentration
with a thickness of at least 10 mm
characterized by lack of roughness
under conditions of ideal adhesion (metal-to-metal)
under vertical application of breakaway force (90-degree angle)
in temp. approx. 20°C

Lifting capacity in real conditions – factors

In practice, the actual lifting capacity is determined by many variables, ranked from crucial:

Distance – the presence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Material type – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was determined using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Warnings

Operating temperature

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

Avoid contact if allergic

It is widely known that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, prevent direct skin contact or select coated magnets.

Phone sensors

A powerful magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.

Shattering risk

NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them cracking into shards.

Machining danger

Machining of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Pinching danger

Large magnets can smash fingers instantly. Under no circumstances put your hand between two strong magnets.

Choking Hazard

Strictly keep magnets out of reach of children. Ingestion danger is significant, and the effects of magnets connecting inside the body are very dangerous.

Caution required

Use magnets consciously. Their huge power can surprise even professionals. Be vigilant and do not underestimate their force.

Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Pacemakers

For implant holders: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.

Caution! Learn more about risks in the article: Magnet Safety Guide.
