Magnetic force weakens sharply with every subsequent millimeter of spacing. Remember that every additional insulation layer (e.g., contamination, varnish, dust) strongly reduces the pull force. Neodymiums work most effectively during direct contact; gap weakens the force. Observe how quickly the parameters drop, when the product does not touch flatly to the metal substrate. When designing the assembly, avoid unnecessary gaps.

Table 2: Slippage force (vertical surface)

The table below indicates the estimated shear load sufficient to cause the sliding of the magnet downwards on a upright steel plate (assuming typical friction coefficient). The holding force is a function of the gap size between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 9.5x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.12 kg / 120.0 g 1.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.08 kg / 80.0 g 0.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 40.0 g 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.20 kg / 200.0 g 2.0 N

When mounting a magnet on a vertical plane (e.g., a car body), it you can count on just approx. 20%-30% of its maximum pull force. Gravitational force as well as a weak degree of grip cause that magnets slide down easier than they pop off the substrate. Want to create a vertical fastening? Note that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the element will slide down under a much lighter load. Using a rubber pad can significantly raise the stability.

Table 4: Material efficiency (substrate influence) - power losses
MW 9.5x1 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.04 kg / 40.0 g 0.4 N
1 mm	25%	0.10 kg / 100.0 g 1.0 N
2 mm	50%	0.20 kg / 200.0 g 2.0 N
5 mm	100%	0.40 kg / 400.0 g 3.9 N
10 mm	100%	0.40 kg / 400.0 g 3.9 N

A thin sheet is incapable of focus the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a thin surface, the flux will penetrate right through and the holding will be smaller. To utilize full efficiency of this neodymium's power, you need a suitably thick piece of steel. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the holder works worse. We recommend selecting the steel cross-section according to the table below.

Table 5: Thermal stability (stability) - resistance threshold
MW 9.5x1 / N38

Ambient temp. (°C)	Power loss	Remaining pull	Status
20 °C	0.0%	0.40 kg / 400.0 g 3.9 N	OK
40 °C	-2.2%	0.39 kg / 391.2 g 3.8 N	OK
60 °C	-4.4%	0.38 kg / 382.4 g 3.8 N
80 °C	-6.6%	0.37 kg / 373.6 g 3.7 N
100 °C	-28.8%	0.28 kg / 284.8 g 2.8 N

Classic neodymiums irreversibly lose parameters after exceeding the maximum temperature. Protect against heat – excessive heat can irreversibly destroy this magnet. With every degree above norm, the magnet's force momentarily drops. Refrain from using this magnet close to heaters exceeding its operating temperature limit. Ignoring the limit will lead to permanent loss of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures than taller cylinders. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and steel combination. The connection of two magnets generates a stronger field and a larger range of performance. Planning to create a strong closure? Apply two magnets instead of one magnet and a striker plate. Remember that when bringing together two magnets, the collision energy is massive. The repulsion force is a bit weaker than the attraction, but still significant.
*Flux density between like poles reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).

Table 7: Hazards (implants) - warnings

Extremely neodym field poses a real danger to electronics and pacemakers. These magnets generate a field that destroys function of sensitive medical devices. Be aware: the unseen radiation acts through matter and housings. Exceptional care must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Dynamics (kinetic energy) - warning

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. Kinetic force can cause material chips or painful pinches to skin. Be sure to control the product during installation so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when handling with powerful specimens.

Warning: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet holds merely approx. 20-30% of its perpendicular strength.

2. Steel saturation

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

3. Power loss vs temp

*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) = 0.16

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 rod magnet, composed of durable NdFeB material, which, at dimensions of Ø9.5x1 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 0.40 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 3.96 N with a weight of only 0.53 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

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., 9.5.1 mm) using epoxy glues. To ensure long-term durability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø9.5x1), 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 9.5 mm and height 1 mm. The value of 3.96 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.53 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 9.5 mm. 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 as well as weaknesses of Nd₂Fe₁₄B magnets.

Benefits

In addition to their pulling strength, neodymium magnets provide the following advantages:

They retain attractive force for nearly 10 years – the loss is just ~1% (according to analyses),
They do not lose their magnetic properties even under strong external field,
In other words, due to the aesthetic surface of nickel, the element gains visual value,
Neodymium magnets ensure maximum magnetic induction on a small area, which increases force concentration,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Possibility of precise creating as well as modifying to complex conditions,
Versatile presence in innovative solutions – they are used in mass storage devices, electric motors, diagnostic systems, and other advanced devices.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Weaknesses

What to avoid - cons of neodymium magnets and proposals for their use:

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complex forms.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
With mass production the cost of neodymium magnets can be a barrier,

Holding force characteristics

Maximum magnetic pulling force – what affects it?

The load parameter shown refers to the peak performance, obtained under optimal environment, namely:

on a plate made of structural steel, effectively closing the magnetic field
whose thickness reaches at least 10 mm
with an ground contact surface
under conditions of gap-free contact (metal-to-metal)
under axial application of breakaway force (90-degree angle)
at temperature room level

Impact of factors on magnetic holding capacity in practice

Effective lifting capacity is influenced by working environment parameters, including (from most important):

Clearance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of nominal force).
Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Material composition – not every steel reacts the same. Alloy additives worsen the attraction effect.
Surface finish – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the load capacity.

H&S for magnets

GPS Danger

An intense magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a device to prevent damaging the sensors.

No play value

Absolutely keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are life-threatening.

Implant safety

Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Magnet fragility

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.

Immense force

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

Keep away from computers

Do not bring magnets close to a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Combustion hazard

Powder generated during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Permanent damage

Do not overheat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).

Allergy Warning

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands or select encased magnets.

Hand protection

Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
