Grip strength decreases sharply with every subsequent millimeter of gap. Note that even a microscopic distance (e.g., dirt, varnish, dust) significantly diminishes the holding power. Magnets work optimally during direct contact; distance weakens the power. Analyze how flashily the pull force fall, when the magnet does not touch tightly to the metal substrate. When planning the arrangement, eliminate redundant distances.

The following data presents the theoretical holding capacity necessary to start the slippage of the magnet vertically against a vertical metal surface (considering standard friction coefficient). This parameter depends on the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 18x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.29 kg / 0.63 pounds 285.0 g / 2.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.19 kg / 0.42 pounds 190.0 g / 1.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.10 kg / 0.21 pounds 95.0 g / 0.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.48 kg / 1.05 pounds 475.0 g / 4.7 N

When mounting a element on a vertical wall (e.g., a fridge), it will maintain only approx. 20%-30% of nominal attraction strength. Gravity as well as a low friction coefficient mean that magnets slip easier than they detach. Want to create a wall mount? Remember that the sliding force is much weaker than the maximum static pull force. On a painted metal, the magnet will slip down under a noticeably lighter weight. Application of an anti-slip layer can effectively raise the stability.

1 mm	25%	0.24 kg / 0.52 pounds 237.5 g / 2.3 N
2 mm	50%	0.48 kg / 1.05 pounds 475.0 g / 4.7 N
3 mm	75%	0.71 kg / 1.57 pounds 712.5 g / 7.0 N
5 mm	100%	0.95 kg / 2.09 pounds 950.0 g / 9.3 N
10 mm	100%	0.95 kg / 2.09 pounds 950.0 g / 9.3 N
11 mm	100%	0.95 kg / 2.09 pounds 950.0 g / 9.3 N
12 mm	100%	0.95 kg / 2.09 pounds 950.0 g / 9.3 N

A thin sheet cannot absorb the entire magnetic field, which wastes potential of the magnet. Should you mount a strong magnet to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To achieve 100% of this magnet's power, you need a suitably thick piece of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the magnet works worse. We recommend selecting the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose parameters above the temperature limit. Watch out for overheating – heat can permanently damage this product. With every degree above norm, the neodymium's capacity briefly decreases. Refrain from using this product near heat sources higher than its working range. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures than long magnets. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and sheet combination. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of operation. Planning to create a solid fastener? Apply two magnets instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still large.
*The magnetic induction in repulsion mode reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Important: Calculations apply to friction force of a pair of matching magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a large risk to electronic devices as well as pacemakers. These neodymiums generate a field that destroys function of sensitive medical devices. Notice: the unseen radiation acts through matter and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (cracking risk) - warning

100 mm	58.12 km/h (16.15 m/s)	0.37 J

NdFeB products are prone to chipping – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Impact energy can cause material chips or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when playing with large magnets.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

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. Wall mount (shear)

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

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly weakens 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) = 0.13

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 presented product is an extremely powerful rod magnet, manufactured from durable NdFeB material, which, with dimensions of Ø18x1.5 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 0.95 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 9.34 N with a weight of only 2.86 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 18.1 mm) using epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø18x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø18x1.5 mm, which, at a weight of 2.86 g, makes it an element with impressive magnetic energy density. The value of 9.34 N means that the magnet is capable of holding a weight many times exceeding its own mass of 2.86 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 1.5 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 diametrically if your project requires it.

Pros and cons of Nd₂Fe₁₄B magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
By applying a lustrous layer of nickel, the element presents an elegant look,
They feature high magnetic induction at the operating surface, which improves attraction properties,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Due to the ability of flexible molding and adaptation to specialized requirements, neodymium magnets can be produced in a variety of forms and dimensions, which amplifies use scope,
Key role in high-tech industry – they serve a role in hard drives, motor assemblies, advanced medical instruments, and technologically advanced constructions.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
Neodymium magnets decrease 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 durability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Limited possibility of producing threads in the magnet and complex forms - preferred is cover - magnetic holder.
Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Furthermore, small components of these devices are able to disrupt the diagnostic process medical when they are in the body.
With mass production the cost of neodymium magnets can be a barrier,

Lifting parameters

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

The lifting capacity listed is a result of laboratory testing performed under specific, ideal conditions:

with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
whose thickness is min. 10 mm
with an polished contact surface
with direct contact (without paint)
during detachment in a direction perpendicular to the mounting surface
in stable room temperature

Determinants of lifting force in real conditions

In real-world applications, the real power is determined by a number of factors, presented from most significant:

Gap (between the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, rust or dirt).
Pull-off angle – note 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.
Plate thickness – too thin sheet causes magnetic saturation, causing part of the flux to be wasted to the other side.
Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Heat – neodymium magnets 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 testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Safe handling of NdFeB magnets

Beware of splinters

NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them shattering into shards.

Physical harm

Watch your fingers. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Be careful!

Do not drill into magnets

Powder produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Handling guide

Use magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their power.

Safe distance

Intense magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.

Danger to pacemakers

Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Do not give to children

Strictly keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.

Power loss in heat

Do not overheat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).

Allergy Warning

Medical facts indicate that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from touching magnets with bare hands and opt for coated magnets.

Magnetic interference

GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
