Magnetic force decreases sharply with every mm of distance. Note that every additional insulation layer (e.g., contamination, paint, dust) noticeably weakens the grip. Magnetic products work optimally at the point of direct contact; distance nullifies the force. Notice how quickly the load capacity plummet, when the product does not touch flatly to the metal substrate. When designing the assembly, eliminate unnecessary gaps.

The table below indicates the theoretical weight limit necessary to cause the sliding of the magnet downwards along a upright steel plate (assuming typical friction). This parameter varies with the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 3x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.06 kg / 0.14 LBS 63.0 g / 0.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.04 kg / 0.09 LBS 42.0 g / 0.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.02 kg / 0.05 LBS 21.0 g / 0.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.11 kg / 0.23 LBS 105.0 g / 1.0 N

When placing a holder on a upright surface (e.g., a board), it will only hold only approx. 1/5 of nominal attraction strength. Gravitational force as well as a low friction coefficient mean that holders move down easier than they pull off. Planning a vertical fastening? Remember that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the magnet will give way down under a significantly smaller weight. Using a rubber coating can effectively raise the stability.

2 mm	50%	0.11 kg / 0.23 LBS 105.0 g / 1.0 N

12 mm	100%	0.21 kg / 0.46 LBS 210.0 g / 2.1 N

A thin metal plate cannot conduct the full magnetic flux, which squanders power of the holder. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To achieve the maximum of this neodymium's potential, you need a suitably thick element of steel. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the product holds weaker. We advise picking the steel thickness based on the following data.

100 °C	-28.8%	0.15 kg / 0.33 LBS 149.5 g / 1.5 N

Classic neodymiums lose strength after exceeding the maximum temperature. Protect against heat – heat can irreversibly demagnetize this magnet. With every degree above norm, the neodymium's power momentarily lowers. Avoid using this product close to ovens higher than its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Engineering note: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low Pc) risk losing magnetic properties sooner 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. The setup of two magnets creates a more powerful interaction and a further horizon of action. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is huge. The levitation is slightly lower than the connection force, but still significant.
*Flux density in repulsion mode is approximately ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Figures demonstrate sliding force of two same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a large risk to electronics as well as pacemakers. These neodymiums produce a field that prevents correct functioning of digital equipment. Notice: the invisible magnetic field penetrates the body and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (kinetic energy) - warning
MW 3x1 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	65.36 km/h (18.16 m/s)	0.01 J
30 mm	113.21 km/h (31.45 m/s)	0.02 J

100 mm	206.68 km/h (57.41 m/s)	0.08 J

Magnetic elements are delicate – a strong collision with metal risks their cracking. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or painful pinches to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when working 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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Note: On a vertical surface, the magnet retains merely ~20% of its max power.

2. Plate thickness effect

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

3. Temperature resistance

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.44

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.

This product is an exceptionally strong cylindrical magnet, composed of modern NdFeB material, which, with dimensions of Ø3x1 mm, guarantees maximum efficiency. The MW 3x1 / N38 model is characterized by a tolerance of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.21 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 2.10 N with a weight of only 0.05 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

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 automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability 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 even stronger magnets in the same volume (Ø3x1), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø3x1 mm, which, at a weight of 0.05 g, makes it an element with impressive magnetic energy density. The value of 2.10 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.05 g. The product has a [NiCuNi] coating, which secures it against external factors, 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 3 mm. 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.

Strengths and weaknesses of rare earth magnets.

Pros

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

They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
They retain their magnetic properties even under external field action,
In other words, due to the shiny layer of gold, the element gains a professional look,
Neodymium magnets deliver maximum magnetic induction on a small surface, which ensures high operational effectiveness,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
Thanks to modularity in constructing and the ability to adapt to individual projects,
Significant place in electronics industry – they find application in computer drives, motor assemblies, precision medical tools, also technologically advanced constructions.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Problematic aspects of neodymium magnets: tips and applications.

They are prone to damage 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 improves its resistance to damage
Neodymium magnets lose 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 durability even at temperatures up to 230°C
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated forms.
Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price exceeds standard values,

Lifting parameters

Magnetic strength at its maximum – what it depends on?

Breakaway force was defined for optimal configuration, including:

using a base made of mild steel, serving as a ideal flux conductor
possessing a thickness of minimum 10 mm to avoid saturation
characterized by lack of roughness
without any insulating layer between the magnet and steel
during detachment in a direction perpendicular to the plane
in temp. approx. 20°C

Magnet lifting force in use – key factors

In practice, the actual lifting capacity depends on many variables, listed from most significant:

Gap (between the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Plate thickness – too thin sheet causes magnetic saturation, causing part of the power to be wasted to the other side.
Plate material – mild steel attracts best. Alloy steels decrease magnetic properties and lifting capacity.
Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the holding force.

Safety rules for work with neodymium magnets

Caution required

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

GPS and phone interference

Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.

Cards and drives

Data protection: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

Bone fractures

Big blocks can smash fingers instantly. Never place your hand between two strong magnets.

Dust explosion hazard

Dust generated during machining of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Fragile material

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

Medical implants

For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.

Allergic reactions

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease handling magnets and wear gloves.

Maximum temperature

Avoid heat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Product not for children

Only for adults. Small elements pose a choking risk, causing severe trauma. Store away from children and animals.
