Magnetic force drops drastically per each millimeter of gap. Remember that even a very thin break (e.g., dirt, paint, veneer) strongly weakens the grip. Neodymiums hold most effectively in perfect adhesion; distance nullifies the force. See how flashily the parameters plummet, when the magnet does not adhere tightly to the steel surface. When designing the arrangement, avoid additional spacers.

The table below shows the estimated holding capacity needed to initiate the downward movement of the magnet vertically against a upright steel plate (assuming standard friction coefficient). The holding force is a function of the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 15x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.13 kg / 0.29 lbs 132.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.19 lbs 88.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.10 lbs 44.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.22 kg / 0.49 lbs 220.0 g / 2.2 N

When placing a magnet on a upright surface (e.g., a car body), it will maintain barely approx. 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient mean that products slide down easier than they pop off the substrate. Planning a vertical fastening? Consider that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slide down under a significantly smaller cargo. Application of an anti-slip pad can significantly increase the grip.

Table 4: Steel thickness (saturation) - sheet metal selection
MW 15x1 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.04 kg / 0.10 lbs 44.0 g / 0.4 N
1 mm	25%	0.11 kg / 0.24 lbs 110.0 g / 1.1 N
2 mm	50%	0.22 kg / 0.49 lbs 220.0 g / 2.2 N
3 mm	75%	0.33 kg / 0.73 lbs 330.0 g / 3.2 N
5 mm	100%	0.44 kg / 0.97 lbs 440.0 g / 4.3 N
10 mm	100%	0.44 kg / 0.97 lbs 440.0 g / 4.3 N
11 mm	100%	0.44 kg / 0.97 lbs 440.0 g / 4.3 N
12 mm	100%	0.44 kg / 0.97 lbs 440.0 g / 4.3 N

A thin sheet is incapable of take in the full magnetic flux, which weakens actual performance of the magnet. Should you install a neodymium to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze 100% of this neodymium's potential, you require a sufficiently solid backing of metal. The saturation phenomenon means that on thin elements (e.g., car bodies), the holder works worse. We advise picking the steel cross-section based on the following data.

Table 5: Working in heat (stability) - thermal limit

40 °C	-2.2%	0.43 kg / 0.95 lbs 430.3 g / 4.2 N	OK
60 °C	-4.4%	0.42 kg / 0.93 lbs 420.6 g / 4.1 N

100 °C	-28.8%	0.31 kg / 0.69 lbs 313.3 g / 3.1 N

Classic neodymiums change their properties strength past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly demagnetize this product. As the temperature rises, the magnet's capacity momentarily drops. Refrain from using this magnet close to ovens exceeding its working range. Too high temperature will cause irreversible degradation of magnetism.

*Engineering note: Heat tolerance is determined by both grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently under lower heat stress than long magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a much further distance than a magnet and sheet combination. The connection of two magnets generates a stronger field and a further horizon of action. Want to build a powerful holder? Use a pair of magnets instead of one magnet and a steel. Be careful that when connecting a pair of magnets, the pinch force is massive. The repulsion force is marginally weaker than the attraction, but still large.
*The magnetic induction in repulsion mode drops to ~0 Gs at the geometric center between the magnets (due to field cancellation).
* Results refer to friction force of two matching magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field poses a real danger to electronic devices as well as medical implants. These magnets generate a field that disrupts operation of digital equipment. Remember: the invisible magnetic field passes through tissues and plastic. Exceptional care must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a violent impact against metal risks their cracking. Control the attraction moment – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or injury to fingers. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the magnet. Wear eye protection when handling with powerful specimens.

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. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical wall, the magnet retains merely approx. 20-30% of its max power.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Temperature resistance

*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) = 0.11

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 presented product is an extremely powerful cylinder magnet, made from advanced NdFeB material, which, with dimensions of Ø15x1 mm, guarantees the highest energy density. The MW 15x1 / N38 component features an accuracy of ±0.1mm and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 0.44 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 4.29 N with a weight of only 1.33 g, this cylindrical magnet 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 immediate cracking of this precision component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability 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 even stronger magnets in the same volume (Ø15x1), 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 15 mm and height 1 mm. The value of 4.29 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.33 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 1 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.

Strengths as well as weaknesses of neodymium magnets.

Pros

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

They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (in testing),
They retain their magnetic properties even under strong external field,
A magnet with a smooth gold surface has an effective appearance,
They feature high magnetic induction at the operating surface, which affects their effectiveness,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to freedom in shaping and the ability to customize to client solutions,
Fundamental importance in high-tech industry – they find application in data components, drive modules, advanced medical instruments, also multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of NdFeB magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
Limited possibility of creating nuts in the magnet and complex forms - preferred is a housing - magnet mounting.
Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small elements of these products can complicate diagnosis medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Magnetic strength at its maximum – what affects it?

Magnet power is the result of a measurement for optimal configuration, including:

with the application of a yoke made of special test steel, ensuring full magnetic saturation
with a cross-section minimum 10 mm
characterized by even structure
with total lack of distance (without impurities)
during pulling in a direction vertical to the mounting surface
at ambient temperature approx. 20 degrees Celsius

Key elements affecting lifting force

Please note that the magnet holding will differ depending on the following factors, starting with the most relevant:

Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Plate thickness – insufficiently thick plate does not accept the full field, causing part of the flux to be escaped to the other side.
Metal type – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

Safe handling of neodymium magnets

Protective goggles

NdFeB magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them breaking into small pieces.

Adults only

Always keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are life-threatening.

Pacemakers

Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.

Metal Allergy

Some people experience a contact allergy to Ni, which is the common plating for neodymium magnets. Extended handling might lead to an allergic reaction. We recommend use protective gloves.

Bone fractures

Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Flammability

Powder created during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Power loss in heat

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Safe operation

Use magnets consciously. Their powerful strength can shock even experienced users. Stay alert and do not underestimate their force.

Cards and drives

Do not bring magnets near a wallet, computer, or TV. The magnetism can destroy these devices and erase data from cards.

GPS Danger

Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
