Pulling power weakens significantly per each millimeter of spacing. Remember that even a microscopic distance (e.g., contamination, varnish, dust) strongly reduces the pull force. Magnetic products hold most effectively in perfect adhesion; air break weakens the force. Analyze how quickly the pull force plummet, when the magnet does not touch directly to the steel surface. When planning the arrangement, eliminate redundant distances.

This section indicates the estimated force required to cause the downward movement of the magnet down on a upright steel wall (assuming typical friction). This value depends on the separation distance between the magnet and the surface.

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

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.12 kg / 0.26 lbs 120.0 g / 1.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.08 kg / 0.18 lbs 80.0 g / 0.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.09 lbs 40.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.20 kg / 0.44 lbs 200.0 g / 2.0 N

When hanging a holder on a upright plane (e.g., a fridge), it will maintain just about 1/5 of its nominal power. Gravity as well as a weak degree of grip influence the fact that magnets slide down faster than they pop off the substrate. Designing a wall mount? Remember that the shear force is much weaker than the perpendicular breakaway force. On a slippery surface, the element will slide down under a significantly smaller load. Application of an anti-slip coating can drastically improve the result.

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

2 mm	50%	0.20 kg / 0.44 lbs 200.0 g / 2.0 N
3 mm	75%	0.30 kg / 0.66 lbs 300.0 g / 2.9 N
5 mm	100%	0.40 kg / 0.88 lbs 400.0 g / 3.9 N

11 mm	100%	0.40 kg / 0.88 lbs 400.0 g / 3.9 N
12 mm	100%	0.40 kg / 0.88 lbs 400.0 g / 3.9 N

A thin metal plate is not enough to take in the full magnetic flux, which squanders power of the holder. Should you install a neodymium to a weak sheet, the flux will pass right through and the pull force will drop sharply. To utilize 100% of this magnet's potential, you need a suitably thick element of metal. The material oversaturation causes that on delicate walls (e.g., car bodies), the magnet shows lower pull force. We recommend selecting the steel dimension according to the table below.

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

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	0.40 kg / 0.88 lbs 400.0 g / 3.9 N	OK
40 °C	-2.2%	0.39 kg / 0.86 lbs 391.2 g / 3.8 N	OK
60 °C	-4.4%	0.38 kg / 0.84 lbs 382.4 g / 3.8 N
80 °C	-6.6%	0.37 kg / 0.82 lbs 373.6 g / 3.7 N
100 °C	-28.8%	0.28 kg / 0.63 lbs 284.8 g / 2.8 N

Standard neodymium magnets change their properties power after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently destroy this product. As the temperature rises, the neodymium's capacity momentarily drops. Avoid using this magnet in hot environments exceeding its working range. Ignoring the limit will cause irreversible degradation of magnetic properties.

*Technical advisory: Thermal stability is determined by both grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnetic products interact from a wider radius than a neodymium and metal setup. Such a system of magnet-to-magnet generates a stronger field and a further horizon of action. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when bringing together two magnets, the impact force is massive. The repulsion force is marginally weaker than the attraction, but still large.
*Flux density for N-N configuration is approximately ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Important: Calculations refer to shear force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a real danger to electronic devices and medical implants. These NdFeB products generate a field that destroys function of sensitive medical devices. Remember: the invisible magnetic field acts through matter and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a violent impact against metal causes immediate chipping. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can destroy the magnet or dangerous crushing to skin. Be sure to control the product during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when working with large magnets.

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. Buoyancy helps in lifting finds.

1. Shear force

*Caution: On a vertical surface, the magnet holds merely a fraction of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) drastically reduces the holding force.

3. Temperature resistance

*For N38 material, the safety limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.16

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 a very strong rod magnet, made from modern NdFeB material, which, at dimensions of Ø9.5x1 mm, guarantees maximum efficiency. This specific item boasts a tolerance of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.40 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force 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.

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 professional component. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø9.5x1), 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 Ø9.5x1 mm, which, at a weight of 0.53 g, makes it an element with high magnetic energy density. 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. 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 diametrically if your project requires it.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Apart from their notable magnetism, neodymium magnets have these key benefits:

Their strength is durable, and after approximately 10 years it drops only by ~1% (theoretically),
They are resistant to demagnetization induced by presence of other magnetic fields,
In other words, due to the glossy layer of nickel, the element gains a professional look,
They show high magnetic induction at the operating surface, making them more effective,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Due to the ability of free molding and adaptation to custom requirements, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which increases their versatility,
Universal use in electronics industry – they are used in mass storage devices, brushless drives, medical devices, as well as complex engineering applications.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of neodymium magnets:

At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complicated forms in magnets, we recommend using a housing - magnetic mount.
Health risk to health – tiny shards of magnets pose a threat, if 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 mass production the cost of neodymium magnets can be a barrier,

Lifting parameters

Maximum lifting capacity of the magnet – what contributes to it?

Holding force of 0.40 kg is a theoretical maximum value executed under the following configuration:

on a plate made of structural steel, optimally conducting the magnetic flux
possessing a thickness of at least 10 mm to avoid saturation
with an ideally smooth contact surface
without the slightest insulating layer between the magnet and steel
during detachment in a direction perpendicular to the plane
at conditions approx. 20°C

Practical lifting capacity: influencing factors

Bear in mind that the application force will differ depending on the following factors, starting with the most relevant:

Distance (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Plate thickness – too thin sheet causes magnetic saturation, causing part of the flux to be lost into the air.
Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
Surface finish – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Warnings

Nickel coating and allergies

Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or opt for versions in plastic housing.

Life threat

Individuals with a ICD should maintain an safe separation from magnets. The magnetism can stop the functioning of the life-saving device.

This is not a toy

Only for adults. Small elements can be swallowed, causing intestinal necrosis. Keep away from children and animals.

Electronic hazard

Do not bring magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.

Respect the power

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

Physical harm

Danger of trauma: The pulling power is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.

Magnetic interference

An intense magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Do not bring magnets close to a smartphone to avoid breaking the sensors.

Machining danger

Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Permanent damage

Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. This process is irreversible.

Shattering risk

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.
