Grip strength decreases drastically with every mm of spacing. Remember that even the smallest gap (e.g., contamination, paint, veneer) significantly weakens the grip. Magnetic products operate most effectively in perfect adhesion; distance weakens the force. Notice how quickly the pull force fall, when the magnet does not touch flatly to the steel surface. When planning the mounting, avoid unnecessary gaps.

The table below indicates the theoretical holding capacity necessary to cause the shifting of the magnet vertically on a upright steel wall (considering typical friction coefficient). The holding force is a function of the gap size between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 12x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.42 kg / 0.92 pounds 417.0 g / 4.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.28 kg / 0.61 pounds 278.0 g / 2.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.14 kg / 0.31 pounds 139.0 g / 1.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.70 kg / 1.53 pounds 695.0 g / 6.8 N

When hanging a element on a upright plane (e.g., a board), it you can count on barely about 1/5 of its maximum pull force. Gravitational force and a weak degree of grip influence the fact that magnets slide down easier than they pop off the substrate. Want to create a wall mount? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the holder will slip down under a noticeably lighter load. Using a rubber coating can effectively raise the stability.

A too thin steel is incapable of focus the entire magnetic field, which squanders power of the magnet. Should you attach a powerful product to a thin surface, the field will pass right through and the pull force will drop sharply. To squeeze full efficiency of this magnet's power, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on thin elements (e.g., car bodies), the holder works worse. We recommend selecting the steel cross-section based on the following data.

Ordinary NdFeB products change their properties parameters after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently demagnetize this product. As the temperature rises, the neodymium's force momentarily drops. Avoid using this magnet close to heaters exceeding its operating temperature limit. Too high temperature will cause irreversible degradation of magnetic properties.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low Pc) are more susceptible to demagnetization at lower temperatures than long magnets. The danger warning in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet setup. The setup of magnet-to-magnet generates a stronger field and a further horizon of action. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the collision energy is massive. The repulsion force is slightly lower than the connection force, but still significant.
*The magnetic induction in repulsion mode drops to ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Important: Figures demonstrate shear force of dual same magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a serious hazard to IT equipment as well as pacemakers. These NdFeB products generate a field that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation passes through tissues and housings. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a collision with steel can result in shattering. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can cause material chips or injury to skin. Always hold the magnet during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when playing with large magnets.

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. Buoyancy helps in lifting finds.

1. Vertical hold

*Warning: On a vertical wall, the magnet retains merely ~20% of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) significantly limits the holding force.

3. Temperature resistance

*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) = 0.25

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 cylinder magnet, made from durable NdFeB material, which, at dimensions of Ø12x2 mm, guarantees the highest energy density. The MW 12x2 / N38 model is characterized by a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.39 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast 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 electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 13.66 N with a weight of only 1.7 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure long-term durability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are strong enough for 90% of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø12x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 12 mm and height 2 mm. The key parameter here is the lifting capacity amounting to approximately 1.39 kg (force ~13.66 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, 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 12 mm. 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.

Pros as well as cons of neodymium magnets.

Pros

Apart from their consistent holding force, neodymium magnets have these key benefits:

Their magnetic field is maintained, and after approximately ten years it drops only by ~1% (theoretically),
They retain their magnetic properties even under strong external field,
The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to look better,
The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Due to the ability of accurate molding and customization to individualized solutions, magnetic components can be manufactured in a wide range of forms and dimensions, which makes them more universal,
Universal use in future technologies – they are used in data components, motor assemblies, advanced medical instruments, also complex engineering applications.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Limitations

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in producing threads and complex shapes in magnets, we recommend using casing - magnetic mount.
Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these devices are able to be problematic in diagnostics medical after entering the body.
With large orders the cost of neodymium magnets is economically unviable,

Pull force analysis

Highest magnetic holding force – what contributes to it?

Magnet power was defined for the most favorable conditions, assuming:

with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
whose transverse dimension equals approx. 10 mm
characterized by smoothness
under conditions of ideal adhesion (metal-to-metal)
for force applied at a right angle (pull-off, not shear)
at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

Effective lifting capacity is affected by specific conditions, mainly (from most important):

Air gap (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
Base massiveness – insufficiently thick steel does not close the flux, causing part of the power to be wasted to the other side.
Material type – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.

Safe handling of neodymium magnets

Fire warning

Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.

Magnetic interference

Navigation devices and smartphones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Power loss in heat

Do not overheat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Material brittleness

Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.

Implant safety

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

Danger to the youngest

These products are not suitable for play. Swallowing multiple magnets can lead to them pinching intestinal walls, which poses a direct threat to life and requires urgent medical intervention.

Magnetic media

Equipment safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

Hand protection

Large magnets can crush fingers instantly. Under no circumstances place your hand between two strong magnets.

Nickel coating and allergies

A percentage of the population suffer from a contact allergy to Ni, which is the standard coating for neodymium magnets. Prolonged contact might lead to dermatitis. It is best to use protective gloves.

Safe operation

Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
