Pulling power drops sharply per each millimeter of spacing. Note that even the smallest gap (e.g., contamination, paint, veneer) noticeably weakens the grip. Magnets work strongest in perfect adhesion; air break nullifies the power. See how quickly the parameters drop, when the magnet does not touch tightly to the metal substrate. When designing the assembly, avoid additional spacers.

The following data defines the approximate weight limit sufficient to start the sliding of the magnet downwards along a vertical metal surface (assuming standard friction). This parameter is a function of the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MW 8x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.55 kg / 1.22 lbs 552.0 g / 5.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.37 kg / 0.81 lbs 368.0 g / 3.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.18 kg / 0.41 lbs 184.0 g / 1.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.92 kg / 2.03 lbs 920.0 g / 9.0 N

When hanging a element on a upright plane (e.g., a fridge), it will only hold barely about 20%-30% of its nominal power. Gravity and a low friction coefficient mean that magnets move down easier than they pop off the substrate. Want to create a hanger? Remember that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the element will give way down under a much lighter cargo. Utilizing a rubberized layer can drastically increase the grip.

A thin sheet cannot absorb the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this neodymium's power, you need a suitably thick element of metal. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the holder holds weaker. We advise picking the steel cross-section according to the table below.

Ordinary NdFeB products irreversibly lose parameters after exceeding the maximum temperature. Protect against heat – heat can irreversibly demagnetize this magnet. With increasing heat, the neodymium's power momentarily decreases. Do not use this magnet near heat sources higher than its operating temperature limit. Ignoring the limit will lead to destruction of magnetism.

*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) risk losing magnetic properties sooner than taller cylinders. Red status in the table points to permanent field degradation for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and sheet combination. The setup of magnet-to-magnet produces a massive flux and a further horizon of operation. Designing a powerful holder? Use a pair of magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the impact force is extreme. The levitation is marginally weaker than the attraction, but still impressive.
*Flux density in repulsion mode drops to ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
* Calculations apply to friction force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a large risk to electronics and pacemakers. These NdFeB products produce a field that prevents correct functioning of digital equipment. Notice: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - warning

100 mm	70.46 km/h (19.57 m/s)	0.72 J

NdFeB products are delicate – a collision with steel can result in shattering. Control the attraction moment – a neodymium left loose turns into a projectile. Impact energy can cause material chips or injury to fingers. Be sure to control the product during mounting so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the magnet. Wear eye protection when working with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains merely a fraction of its nominal pull.

2. Steel saturation

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

3. Heat tolerance

*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) = 1.00

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 offered product is an extremely powerful rod magnet, composed of advanced NdFeB material, which, with dimensions of Ø8x10 mm, guarantees the highest energy density. The MW 8x10 / N38 component features high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 1.84 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects 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 high power of 18.00 N with a weight of only 3.77 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use 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 durability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø8x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø8x10 mm, which, at a weight of 3.77 g, makes it an element with high magnetic energy density. The value of 18.00 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.77 g. The product has a [NiCuNi] coating, which protects the surface 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 8 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 diametrically if your project requires it.

Advantages as well as disadvantages of neodymium magnets.

Pros

Besides their remarkable field intensity, neodymium magnets offer the following advantages:

They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
Neodymium magnets are characterized by exceptionally resistant to loss of magnetic properties caused by external field sources,
The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to look better,
They feature high magnetic induction at the operating surface, making them more effective,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
In view of the potential of precise shaping and customization to unique requirements, neodymium magnets can be manufactured in a variety of shapes and sizes, which amplifies use scope,
Universal use in modern technologies – they are commonly used in computer drives, brushless drives, advanced medical instruments, also multitasking production systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
Neodymium magnets decrease their force 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 rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing nuts and complicated forms in magnets, we propose using a housing - magnetic holder.
Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets is economically unviable,

Lifting parameters

Highest magnetic holding force – what affects it?

Holding force of 1.84 kg is a measurement result conducted under specific, ideal conditions:

with the use of a sheet made of special test steel, ensuring full magnetic saturation
whose thickness equals approx. 10 mm
characterized by even structure
under conditions of gap-free contact (metal-to-metal)
under axial force direction (90-degree angle)
at ambient temperature room level

What influences lifting capacity in practice

It is worth knowing that the magnet holding may be lower subject to the following factors, in order of importance:

Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Steel grade – ideal substrate is pure iron steel. Hardened steels may attract less.
Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.

Safety rules for work with neodymium magnets

Fragile material

NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets will cause them cracking into shards.

Dust explosion hazard

Machining of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Permanent damage

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.

Bone fractures

Protect your hands. Two large magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!

Warning for heart patients

Individuals with a heart stimulator must maintain an safe separation from magnets. The magnetic field can interfere with the functioning of the life-saving device.

Skin irritation risks

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease working with magnets and wear gloves.

Electronic hazard

Device Safety: Strong magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, timepieces).

Do not give to children

Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep away from children and animals.

GPS Danger

GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Caution required

Use magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and respect their power.
