Grip strength drops significantly with every subsequent millimeter of spacing. Keep in mind that even the smallest gap (e.g., dirt, paint, rust) noticeably reduces the pull force. Magnetic products work most effectively at the point of direct contact; distance kills the power. See how flashily the parameters drop, when the magnet does not adhere tightly to the steel surface. When calculating the assembly, discard redundant distances.

This section indicates the estimated force needed to cause the shifting of the magnet down against a upright metal surface (assuming standard friction coefficient). This value varies with the air gap between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 10x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.58 kg / 1.27 pounds 576.0 g / 5.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.85 pounds 384.0 g / 3.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.42 pounds 192.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.96 kg / 2.12 pounds 960.0 g / 9.4 N

When placing a element on a vertical wall (e.g., a fridge), it you can count on just approx. 1/5 of its maximum pull force. Gravity and a weak degree of grip influence the fact that magnets slip easier than they detach. Want to create a hanger? Consider that the shear force is much weaker than the maximum static pull force. On a painted metal, the holder will slip down under a much lighter load. Using a rubber pad can drastically improve the result.

A thin sheet is incapable of conduct the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the field will penetrate right through and the holding will be smaller. To utilize 100% of this neodymium's power, you require a sufficiently solid piece of metal. The material oversaturation causes that on delicate walls (e.g., appliance housings), the product holds weaker. We suggest choosing the steel thickness according to the table below.

Table 5: Thermal resistance (stability) - power drop

Classic neodymiums lose power above the temperature limit. Avoid high temperatures – heat can permanently demagnetize this product. With increasing heat, the magnet's power temporarily lowers. Do not use this product close to ovens higher than its operating temperature limit. Too high temperature will result in irreversible degradation of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of performance. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the collision energy is huge. The repulsion force is marginally weaker than the connection force, but still significant.
*The magnetic induction for N-N configuration drops to ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Attention: Results refer to shear force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Safety (HSE) (implants) - warnings

Extremely neodym field poses a serious hazard to electronic devices as well as pacemakers. These neodymiums generate a flux that disrupts operation of digital equipment. Remember: the unseen radiation acts through matter and plastic. Special caution must be taken by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Collisions (cracking risk) - collision effects
MW 10x30 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	10.58 km/h (2.94 m/s)	0.08 J
30 mm	18.21 km/h (5.06 m/s)	0.23 J
50 mm	23.51 km/h (6.53 m/s)	0.38 J
100 mm	33.24 km/h (9.23 m/s)	0.75 J

NdFeB products are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when playing with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Note: On a vertical surface, the magnet retains just ~20% of its perpendicular strength.

2. Plate thickness effect

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

3. Heat tolerance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.38

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.

This product is a very strong rod magnet, composed of modern NdFeB material, which, at dimensions of Ø10x30 mm, guarantees the highest energy density. This specific item is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.92 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 18.79 N with a weight of only 17.67 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. 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 professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø10x30), 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 10 mm and height 30 mm. The value of 18.79 N means that the magnet is capable of holding a weight many times exceeding its own mass of 17.67 g. The product has a [NiCuNi] coating, which secures it 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 10 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 through the diameter if your project requires it.

Advantages as well as disadvantages of rare earth magnets.

Pros

Besides their stability, neodymium magnets are valued for these benefits:

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
Neodymium magnets are distinguished by remarkably resistant to magnetic field loss caused by external field sources,
A magnet with a metallic nickel surface has better aesthetics,
Magnets are characterized by impressive magnetic induction on the outer side,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Possibility of precise shaping as well as optimizing to atypical conditions,
Significant place in modern industrial fields – they are commonly used in mass storage devices, motor assemblies, advanced medical instruments, also other advanced devices.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:

At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's 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.
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
Limited possibility of creating nuts in the magnet and complex shapes - preferred is casing - magnet mounting.
Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Maximum holding power of the magnet – what affects it?

Breakaway force was defined for ideal contact conditions, including:

on a block made of mild steel, effectively closing the magnetic flux
possessing a thickness of at least 10 mm to ensure full flux closure
with a plane cleaned and smooth
with total lack of distance (without impurities)
during detachment in a direction vertical to the mounting surface
at standard ambient temperature

Determinants of lifting force in real conditions

In practice, the actual holding force is determined by many variables, listed from crucial:

Air gap (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Steel type – mild steel attracts best. Alloy steels lower magnetic permeability and holding force.
Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Warnings

Handling rules

Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.

Cards and drives

Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.

Adults only

Absolutely keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are fatal.

Life threat

Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Hand protection

Risk of injury: The attraction force is so immense that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.

Combustion hazard

Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.

Keep away from electronics

Be aware: neodymium magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.

Demagnetization risk

Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.

Beware of splinters

Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

Metal Allergy

A percentage of the population experience a contact allergy to Ni, which is the standard coating for neodymium magnets. Frequent touching can result in skin redness. We suggest wear safety gloves.
