Grip strength decreases sharply with every mm of distance. Keep in mind that even a very thin break (e.g., contamination, paint, rust) strongly diminishes the holding power. Magnets hold optimally during direct contact; gap drastically cuts the force. See how quickly the pull force fall, when the product does not touch flatly to the steel surface. When planning the mounting, avoid additional spacers.

The following data indicates the theoretical shear load sufficient to cause the downward movement of the magnet vertically against a upright steel plate (considering standard friction). This value is a function of the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 10x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.01 kg / 2.24 lbs 1014.0 g / 9.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.68 kg / 1.49 lbs 676.0 g / 6.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.34 kg / 0.75 lbs 338.0 g / 3.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.69 kg / 3.73 lbs 1690.0 g / 16.6 N

When mounting a element on a upright wall (e.g., a fridge), it will only hold only about 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient mean that holders slip easier than they pop off the substrate. Planning a vertical fastening? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will give way down under a noticeably lighter weight. Using a rubber coating can drastically increase the grip.

12 mm	100%	3.38 kg / 7.45 lbs 3380.0 g / 33.2 N

A thin sheet is incapable of conduct the full magnetic flux, which weakens actual performance of the magnet. Should you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this magnet's potential, you need a suitably thick backing of steel. The saturation effect causes that on thin elements (e.g., appliance housings), the holder works worse. We advise picking the steel dimension according to the table below.

Standard neodymium magnets irreversibly lose parameters above the temperature limit. Protect against heat – excessive heat can irreversibly damage this magnet. As the temperature rises, the neodymium's power temporarily decreases. Refrain from using this product close to ovens higher than its operating temperature limit. Ignoring the limit will result in irreversible degradation of magnetic properties.

*Technical advisory: Thermal stability is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) risk losing magnetic properties under lower heat stress than long magnets. Red status in the table points to permanent field degradation for this particular item.

Two magnets attract each other from a much further distance than a magnet and steel combination. The setup of two magnets produces a massive flux and a wider radius of action. Designing a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the impact force is massive. The levitation is a bit weaker than the connection force, but still large.
*Flux density for N-N configuration drops to ~0 Gs in the exact middle of the gap (due to field cancellation).
Note: Calculations show shear force of two matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field is a serious hazard to electronic devices as well as medical implants. These NdFeB products produce a field that destroys function of sensitive medical devices. Notice: the unseen radiation acts through matter and glass. Special caution must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely turns into a projectile. Kinetic force can trigger coating fragments or painful pinches to fingers. Be sure to control the product 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. Use safety goggles when handling with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Shear force

*Caution: On a vertical wall, the magnet holds just approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

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

3. Heat tolerance

*For standard magnets, 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) = 0.79

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 an extremely powerful cylindrical magnet, composed of advanced NdFeB material, which, with dimensions of Ø10x8 mm, guarantees optimal power. The MW 10x8 / N38 model boasts an accuracy 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. 3.38 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Moreover, 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 created for building generators, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 33.16 N with a weight of only 4.71 g, this rod 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., 10.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets N38 are strong enough for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø10x8), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 8 mm. The value of 33.16 N means that the magnet is capable of holding a weight many times exceeding its own mass of 4.71 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 8 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 diametrically if your project requires it.

Strengths and weaknesses of neodymium magnets.

Benefits

Besides their immense magnetic power, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
Magnets effectively protect themselves against loss of magnetization caused by external fields,
In other words, due to the metallic layer of nickel, the element becomes visually attractive,
Magnets exhibit very high magnetic induction on the surface,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of exact creating and adapting to atypical applications,
Fundamental importance in innovative solutions – they are commonly used in hard drives, drive modules, precision medical tools, and industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices

Weaknesses

Problematic aspects of neodymium magnets: application proposals

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. 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 power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
Limited possibility of creating threads in the magnet and complex forms - recommended is cover - mounting mechanism.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these devices are able to complicate diagnosis medical when they are in the body.
With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum magnetic pulling force – what affects it?

The lifting capacity listed is a theoretical maximum value executed under the following configuration:

on a plate made of structural steel, perfectly concentrating the magnetic flux
whose transverse dimension reaches at least 10 mm
with a surface free of scratches
without the slightest insulating layer between the magnet and steel
during detachment in a direction vertical to the plane
at ambient temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

Please note that the working load will differ depending on elements below, starting with the most relevant:

Clearance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Plate thickness – too thin steel does not accept the full field, causing part of the flux to be wasted to the other side.
Steel type – mild steel gives the best results. Alloy steels lower magnetic properties and holding force.
Surface condition – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
Thermal environment – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.

Safe handling of neodymium magnets

Protective goggles

Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.

Immense force

Handle magnets with awareness. Their immense force can surprise even professionals. Stay alert and respect their force.

Medical implants

Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Electronic devices

Data protection: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, timepieces).

Power loss in heat

Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).

Skin irritation risks

Certain individuals have a contact allergy to Ni, which is the standard coating for neodymium magnets. Prolonged contact can result in skin redness. It is best to wear protective gloves.

Do not drill into magnets

Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.

Threat to navigation

A strong magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Do not bring magnets close to a device to prevent breaking the sensors.

No play value

Absolutely store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are very dangerous.

Crushing risk

Big blocks can crush fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
