Magnetic force drops drastically per each millimeter of spacing. Remember that even a microscopic distance (e.g., contamination, varnish, dust) significantly weakens the grip. Magnets hold most effectively during direct contact; distance weakens the power. Notice how quickly the load capacity drop, when the product does not touch flatly to the metal substrate. When calculating the mounting, discard additional spacers.

The table below defines the approximate force required to cause the sliding of the magnet vertically on a upright metal surface (assuming typical friction coefficient). This parameter is a function of the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 28.9x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	6.22 kg / 13.72 lbs 6222.0 g / 61.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.15 kg / 9.14 lbs 4148.0 g / 40.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.07 kg / 4.57 lbs 2074.0 g / 20.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	10.37 kg / 22.86 lbs 10370.0 g / 101.7 N

When placing a magnet on a vertical surface (e.g., a board), it you can count on barely about 20%-30% of its nominal power. Gravitational force and a low friction coefficient cause that products move down faster than they pop off the substrate. Planning a vertical fastening? Consider that the shear force is much weaker than the maximum static pull force. On a painted metal, the holder will give way down under a much lighter weight. Application of an anti-slip coating can effectively raise the stability.

3 mm	38%	7.78 kg / 17.15 lbs 7777.5 g / 76.3 N
5 mm	63%	12.96 kg / 28.58 lbs 12962.5 g / 127.2 N
10 mm	100%	20.74 kg / 45.72 lbs 20740.0 g / 203.5 N
11 mm	100%	20.74 kg / 45.72 lbs 20740.0 g / 203.5 N
12 mm	100%	20.74 kg / 45.72 lbs 20740.0 g / 203.5 N

A thin sheet is incapable of focus the entire magnetic field, which weakens actual performance of the magnet. If you install a neodymium to a too thin substrate, the field will pass right through and the attraction force will be weaker. To utilize 100% of this neodymium's power, you need a suitably thick piece of steel. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the holder holds weaker. We recommend selecting the steel dimension from these parameters.

Standard neodymium magnets change their properties parameters past the thermal threshold. Watch out for overheating – excessive heat can permanently destroy this product. With increasing heat, the magnet's force temporarily decreases. Refrain from using this product near heat sources exceeding its safe range. Exceeding the critical threshold will result in destruction of magnetic properties.

*Important note: Temperature resistance is determined by both grade, as well as the dimension ratios. Thin magnets (pancake types) may lose charge permanently under lower heat stress compared to rod magnets. Red status in the table points to permanent field degradation for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and sheet combination. Such a system of two magnets creates a more powerful interaction and a wider radius of action. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a steel. Remember that when bringing together two magnets, the pinch force is extreme. The repulsion force is slightly lower than the attraction, but still large.
*Flux density between like poles is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Calculations demonstrate sliding force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

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

Powerful magnet radiation poses a real danger to electronics and pacemakers. These magnets generate a field that disrupts operation of digital equipment. Remember: the unseen radiation acts through matter and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - collision effects
MW 28.9x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	22.92 km/h (6.37 m/s)	1.00 J
30 mm	35.97 km/h (9.99 m/s)	2.46 J
50 mm	46.31 km/h (12.86 m/s)	4.07 J
100 mm	65.48 km/h (18.19 m/s)	8.14 J

NdFeB products are delicate – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can cause material chips or painful pinches to skin. 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 means shattering of the neodymium. 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!

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet holds only ~20% of its nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) severely 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) = 0.45

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.

The offered product is an extremely powerful cylindrical magnet, manufactured from durable NdFeB material, which, with dimensions of Ø28.9x10 mm, guarantees optimal power. This specific item is characterized by an accuracy of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 20.74 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating effectively protects 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 maximum induction on a small surface counts. Thanks to the pull force of 203.46 N with a weight of only 49.2 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 28.9.1 mm) using epoxy glues. To ensure long-term durability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø28.9x10), 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 28.9 mm and height 10 mm. The value of 203.46 N means that the magnet is capable of holding a weight many times exceeding its own mass of 49.2 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 28.9 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.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Pros

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

Their strength is durable, and after around ten years it drops only by ~1% (according to research),
Neodymium magnets prove to be highly resistant to magnetic field loss caused by external magnetic fields,
A magnet with a metallic gold surface has better aesthetics,
Magnetic induction on the top side of the magnet is very high,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Thanks to freedom in designing and the capacity to modify to complex applications,
Significant place in future technologies – they are used in computer drives, motor assemblies, precision medical tools, and modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Cons

Characteristics of disadvantages of neodymium magnets and proposals for their use:

To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complex forms.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Furthermore, small components of these products are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting force for a neodymium magnet – what contributes to it?

Holding force of 20.74 kg is a result of laboratory testing performed under the following configuration:

on a base made of mild steel, effectively closing the magnetic flux
possessing a massiveness of min. 10 mm to avoid saturation
characterized by lack of roughness
with zero gap (without coatings)
under perpendicular application of breakaway force (90-degree angle)
in temp. approx. 20°C

Determinants of practical lifting force of a magnet

Holding efficiency is influenced by working environment parameters, such as (from most important):

Clearance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material type – the best choice is high-permeability steel. Stainless steels may attract less.
Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Safe handling of neodymium magnets

Metal Allergy

Certain individuals suffer from a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause dermatitis. It is best to use safety gloves.

Magnetic interference

A powerful magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.

Fire risk

Dust produced during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Keep away from computers

Do not bring magnets near a purse, laptop, or screen. The magnetic field can destroy these devices and wipe information from cards.

This is not a toy

Always keep magnets away from children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are very dangerous.

Thermal limits

Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Magnets are brittle

Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.

Caution required

Use magnets with awareness. Their huge power can shock even professionals. Plan your moves and do not underestimate their power.

Danger to pacemakers

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Serious injuries

Protect your hands. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Be careful!
