Magnetic force drops significantly with every subsequent millimeter of distance. Note that every additional insulation layer (e.g., contamination, varnish, veneer) noticeably weakens the grip. Neodymiums operate most effectively at the point of direct contact; distance drastically cuts the power. Observe how quickly the pull force fall, when the magnet does not adhere flatly to the steel surface. When planning the assembly, eliminate additional spacers.

The table below presents the estimated force sufficient to start the shifting of the magnet vertically against a vertical steel wall (assuming typical friction coefficient). This value is relative to the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 12x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.75 kg / 1.65 pounds 747.0 g / 7.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.50 kg / 1.10 pounds 498.0 g / 4.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.25 kg / 0.55 pounds 249.0 g / 2.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.25 kg / 2.74 pounds 1245.0 g / 12.2 N

When placing a element on a vertical surface (e.g., a car body), it will only hold only approx. 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip mean that magnets slip easier than they pull off. Designing a wall mount? Consider that the shear force is much weaker than the perpendicular breakaway force. On a slippery surface, the element will slip down under a significantly smaller cargo. Utilizing a rubberized layer can drastically increase the grip.

12 mm	100%	2.49 kg / 5.49 pounds 2490.0 g / 24.4 N

A too thin steel is unable to conduct the full magnetic flux, which squanders power of the holder. Should you mount a strong magnet to a weak sheet, the flux will pass right through and the pull force will drop sharply. To achieve 100% of this magnet's potential, you need a suitably thick piece of steel. The material oversaturation causes that on sheet metal structures (e.g., thin profiles), the holder works worse. We advise picking the steel dimension from these parameters.

Standard neodymium magnets lose strength after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently destroy this magnet. As the temperature rises, the neodymium's power briefly decreases. Do not use this magnet close to ovens exceeding its safe range. Ignoring the limit will lead to destruction of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low Pc) may lose charge permanently sooner compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and sheet combination. Such a system of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Designing a strong closure? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is massive. The levitation is marginally weaker than the connection force, but still impressive.
*Flux density between like poles is approximately ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Attention: Results apply to friction force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a real danger to IT equipment and pacemakers. These magnets produce a field that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field acts through matter and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, remotes, membranes, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are prone to chipping – a strong collision with metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can cause material chips or painful pinches to fingers. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when working with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

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. Vertical hold

*Caution: On a vertical wall, the magnet retains just a fraction of its max power.

2. Efficiency vs thickness

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

3. Thermal stability

*For N38 material, 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) = 0.35

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 cylindrical magnet, composed of durable NdFeB material, which, at dimensions of Ø12x3 mm, guarantees the highest energy density. The MW 12x3 / N38 component is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 2.49 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 24.43 N with a weight of only 2.54 g, this cylindrical magnet 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 do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø12x3), 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 Ø12x3 mm, which, at a weight of 2.54 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 2.49 kg (force ~24.43 N), which, with such defined dimensions, proves the high power of the NdFeB material. 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 3 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable 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.

Strengths

Besides their high retention, neodymium magnets are valued for these benefits:

Their power is maintained, and after approximately 10 years it decreases only by ~1% (according to research),
Magnets perfectly defend themselves against demagnetization caused by external fields,
The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnetic induction on the surface of the magnet is very high,
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...
Possibility of accurate shaping and optimizing to complex applications,
Fundamental importance in modern technologies – they serve a role in magnetic memories, brushless drives, medical equipment, also multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:

At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's 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 stability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing threads and complex shapes in magnets, we recommend using casing - magnetic holder.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these products can complicate diagnosis medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting force for a neodymium magnet – what it depends on?

The force parameter is a result of laboratory testing conducted under standard conditions:

on a base made of structural steel, optimally conducting the magnetic flux
whose transverse dimension reaches at least 10 mm
with a surface cleaned and smooth
without any clearance between the magnet and steel
during pulling in a direction vertical to the plane
in neutral thermal conditions

Lifting capacity in real conditions – factors

In practice, the actual lifting capacity results from a number of factors, presented from crucial:

Distance – existence of any layer (paint, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Angle of force application – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
Plate material – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the holding force.

Precautions when working with neodymium magnets

Life threat

Patients with a heart stimulator must keep an large gap from magnets. The magnetic field can disrupt the functioning of the implant.

Adults only

Always store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are life-threatening.

Electronic devices

Do not bring magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.

Keep away from electronics

A powerful magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Maintain magnets near a device to prevent breaking the sensors.

Demagnetization risk

Do not overheat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Nickel allergy

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop handling magnets and use protective gear.

Magnet fragility

Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.

Machining danger

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

Physical harm

Mind your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Powerful field

Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
