Pulling power weakens drastically with every subsequent millimeter of spacing. Keep in mind that even a very thin break (e.g., dirt, varnish, veneer) significantly diminishes the holding power. Magnets hold most effectively during direct contact; air break nullifies the force. Notice how flashily the parameters drop, when the product does not adhere directly to the metal substrate. When calculating the assembly, avoid redundant distances.

The table below indicates the approximate weight limit needed to initiate the downward movement of the magnet down on a upright metal surface (assuming typical friction coefficient). This value varies with the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MW 20x35 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.87 kg / 6.34 LBS 2874.0 g / 28.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.92 kg / 4.22 LBS 1916.0 g / 18.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.96 kg / 2.11 LBS 958.0 g / 9.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.79 kg / 10.56 LBS 4790.0 g / 47.0 N

When hanging a magnet on a vertical surface (e.g., a board), it will only hold just approx. 1/5 of its nominal power. Gravity as well as a low friction coefficient influence the fact that magnets slip faster than they pull off. Want to create a vertical fastening? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a noticeably lighter load. Utilizing a rubberized coating can significantly improve the result.

12 mm	100%	9.58 kg / 21.12 LBS 9580.0 g / 94.0 N

A thin sheet is not enough to focus the full magnetic flux, which wastes potential of the magnet. Should you mount a strong magnet to a thin surface, the flux will penetrate right through and the holding will be smaller. To squeeze full efficiency of this neodymium's power, you require a sufficiently solid element of metal. The saturation effect causes that on sheet metal structures (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel thickness from these parameters.

Classic neodymiums irreversibly lose strength above the temperature limit. Watch out for overheating – high temperature can irreversibly damage this product. As the temperature rises, the neodymium's capacity temporarily drops. Refrain from using this magnet close to heaters exceeding its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) may lose charge permanently sooner compared to rod magnets. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal combination. The setup of magnet-to-magnet produces a massive flux and a further horizon of action. Designing a powerful holder? Apply two magnets instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the collision energy is extreme. The levitation is a bit weaker than the connection force, but still significant.
*Flux density for N-N configuration is approximately ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Note: Figures apply to sliding force of dual same neodymium magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field is a real danger to IT equipment as well as pacemakers. These NdFeB products produce a flux that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field acts through matter and plastic. Special caution must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

100 mm	34.37 km/h (9.55 m/s)	3.76 J

Magnetic elements are very brittle – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or painful pinches to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear safety glasses when working with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Note: On a vertical surface, the magnet holds just a fraction of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Thermal stability

*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) = 1.16

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 extremely powerful cylinder magnet, manufactured from modern NdFeB material, which, at dimensions of Ø20x35 mm, guarantees the highest energy density. The MW 20x35 / N38 component is characterized by a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 9.58 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard 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 93.97 N with a weight of only 82.47 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 20.1 mm) using two-component epoxy glues. 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 suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø20x35), 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 Ø20x35 mm, which, at a weight of 82.47 g, makes it an element with impressive magnetic energy density. The value of 93.97 N means that the magnet is capable of holding a weight many times exceeding its own mass of 82.47 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 35 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Pros as well as cons of neodymium magnets.

Advantages

Besides their immense strength, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
They have excellent resistance to magnetic field loss as a result of external magnetic sources,
In other words, due to the aesthetic layer of nickel, the element becomes visually attractive,
The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Thanks to flexibility in constructing and the ability to adapt to client solutions,
Fundamental importance in high-tech industry – they are used in computer drives, drive modules, precision medical tools, as well as other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
We warn that neodymium magnets can reduce their strength 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 during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We recommend a housing - magnetic holder, due to difficulties in creating threads inside the magnet and complicated forms.
Health risk resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Additionally, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

The specified lifting capacity concerns the limit force, obtained under ideal test conditions, meaning:

using a plate made of high-permeability steel, serving as a magnetic yoke
whose transverse dimension is min. 10 mm
with a plane free of scratches
under conditions of no distance (metal-to-metal)
for force applied at a right angle (pull-off, not shear)
at conditions approx. 20°C

Determinants of lifting force in real conditions

It is worth knowing that the application force may be lower subject to elements below, in order of importance:

Clearance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Plate material – mild steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

H&S for magnets

Allergic reactions

Medical facts indicate that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands or select versions in plastic housing.

Health Danger

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Precision electronics

A powerful magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Keep magnets close to a smartphone to prevent breaking the sensors.

Operating temperature

Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Physical harm

Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.

Conscious usage

Use magnets with awareness. Their immense force can surprise even professionals. Be vigilant and respect their force.

Adults only

Strictly store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are fatal.

Magnetic media

Equipment safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, medical aids, mechanical watches).

Shattering risk

Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
