Magnetic force drops significantly per each millimeter of distance. Keep in mind that even the smallest gap (e.g., dirt, paint, veneer) significantly diminishes the holding power. Magnets work most effectively in perfect adhesion; gap drastically cuts the force. Observe how flashily the parameters plummet, when the product does not touch flatly to the steel surface. When calculating the assembly, avoid unnecessary gaps.

This section indicates the estimated shear load sufficient to initiate the sliding of the magnet downwards along a upright steel wall (considering typical friction). This value depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 12x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.13 kg / 0.28 LBS 126.0 g / 1.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.08 kg / 0.19 LBS 84.0 g / 0.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.09 LBS 42.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.21 kg / 0.46 LBS 210.0 g / 2.1 N

When hanging a element on a vertical wall (e.g., a board), it you can count on barely approx. 1/5 of its nominal power. Gravitational force as well as a weak degree of grip mean that products slide down easier than they detach. Designing a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slip down under a significantly smaller cargo. Application of an anti-slip layer can drastically improve the result.

A too thin steel is unable to absorb the entire magnetic field, which squanders power of the magnet. Should you install a neodymium to a weak sheet, the flux will pass right through and the attraction force will be weaker. To achieve full efficiency of this magnet's power, you require a sufficiently solid element of metal. The material oversaturation means that on thin elements (e.g., appliance housings), the holder shows lower pull force. We suggest choosing the steel dimension based on the following data.

Ordinary NdFeB products lose power past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly demagnetize this magnet. As the temperature rises, the magnet's force temporarily lowers. Avoid using this magnet close to heaters higher than its operating temperature limit. Exceeding the critical threshold 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. Flat magnets (low Pc) may lose charge permanently under lower heat stress than long magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a neodymium and metal combination. The setup of two magnets produces a massive flux and a further horizon of operation. Want to build a solid fastener? Apply two magnets instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the impact force is extreme. The levitation is slightly lower than the attraction, but still large.
*Field value in repulsion mode reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
* Calculations demonstrate shear force of a pair of same magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Safety (HSE) (electronics) - precautionary measures

A strong magnetic field is a large risk to electronic devices as well as pacemakers. These magnets generate a flux that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are very brittle – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose speeds with massive force. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when working with powerful specimens.

Water (riverbed)	0.48 kg (+0.06 kg buoyancy gain)	+14.5%

Corrosion warning: 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. Vertical hold

*Warning: On a vertical wall, the magnet holds only approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) significantly reduces 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) = 0.13

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 a very strong cylindrical magnet, made from durable NdFeB material, which, with dimensions of Ø12x1 mm, guarantees the highest energy density. The MW 12x1 / N38 model features high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 0.42 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 4.15 N with a weight of only 0.85 g, this rod is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 12.1 mm) using epoxy glues. 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 N38 are suitable for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø12x1), 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 12 mm and height 1 mm. The value of 4.15 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.85 g. 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 1 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard 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 neodymium magnets.

Pros

Besides their exceptional field intensity, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
Magnets effectively resist against demagnetization caused by foreign field sources,
The use of an refined coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Due to the option of flexible molding and customization to unique needs, NdFeB magnets can be produced in a wide range of shapes and sizes, which makes them more universal,
Wide application in innovative solutions – they are utilized in hard drives, electromotive mechanisms, medical devices, also modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
Limited possibility of creating threads in the magnet and complicated forms - preferred is a housing - magnetic holder.
Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these products can complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price is higher than average,

Pull force analysis

Maximum magnetic pulling force – what contributes to it?

Information about lifting capacity was determined for the most favorable conditions, including:

using a sheet made of mild steel, acting as a circuit closing element
whose thickness is min. 10 mm
with a plane cleaned and smooth
under conditions of no distance (surface-to-surface)
for force applied at a right angle (pull-off, not shear)
in stable room temperature

Determinants of practical lifting force of a magnet

Please note that the working load will differ depending on elements below, starting with the most relevant:

Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Load vector – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Plate material – mild steel gives the best results. Higher carbon content decrease magnetic properties and lifting capacity.
Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.

Precautions when working with NdFeB magnets

Conscious usage

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

Precision electronics

A powerful magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Keep magnets near a device to prevent damaging the sensors.

Safe distance

Do not bring magnets close to a purse, computer, or screen. The magnetic field can destroy these devices and erase data from cards.

Allergic reactions

It is widely known that nickel (standard magnet coating) is a potent allergen. If you have an allergy, refrain from direct skin contact or opt for encased magnets.

Life threat

Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.

Demagnetization risk

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Dust is flammable

Powder created during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Product not for children

Only for adults. Tiny parts can be swallowed, leading to severe trauma. Store out of reach of kids and pets.

Bodily injuries

Big blocks can break fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.

Beware of splinters

Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
