Grip strength drops drastically with every subsequent millimeter of distance. Keep in mind that every additional insulation layer (e.g., dirt, paint, rust) significantly diminishes the holding power. Magnetic products operate most effectively at the point of direct contact; distance nullifies the power. Notice how flashily the load capacity plummet, when the magnet does not touch directly to the steel surface. When designing the arrangement, avoid redundant distances.

The table below defines the estimated force needed to start the shifting of the magnet down against a upright metal surface (considering standard friction). This parameter depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 8x15 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.44 kg / 0.97 LBS 441.0 g / 4.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.29 kg / 0.65 LBS 294.0 g / 2.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.15 kg / 0.32 LBS 147.0 g / 1.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.74 kg / 1.62 LBS 735.0 g / 7.2 N

When mounting a magnet on a upright plane (e.g., a board), it you can count on just approx. 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that magnets slide down easier than they pull off. Planning a wall mount? Remember that the shear force is much weaker than the maximum static pull force. On a painted metal, the holder will slide down under a significantly smaller cargo. Using a rubber layer can significantly improve the result.

12 mm	100%	1.47 kg / 3.24 LBS 1470.0 g / 14.4 N

A too thin steel is unable to focus the full magnetic flux, which squanders power of the magnet. Should you mount a strong magnet to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To utilize 100% of this neodymium's potential, you require a sufficiently solid piece of metal. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the magnet works worse. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products lose parameters after exceeding the maximum temperature. Protect against heat – heat can permanently damage this product. With increasing heat, the magnet's force briefly drops. Do not use this product in hot environments higher than its working range. Too high temperature will result in destruction of magnetism.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table signals permanent field degradation for this particular item.

Two strong neodymiums attract each other from a wider radius than a magnet and sheet combination. The connection of two magnets creates a more powerful interaction and a further horizon of performance. Want to build a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the pinch force is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*Flux density in repulsion mode is approximately ~0 Gs in the exact middle of the gap (resulting from vector opposition).
* Figures apply to sliding force of a pair of same magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a real danger to electronic devices as well as medical implants. These neodymiums generate a flux that destroys function of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and glass. Exceptional care must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	16.31 km/h (4.53 m/s)	0.06 J

50 mm	36.37 km/h (10.10 m/s)	0.29 J
100 mm	51.44 km/h (14.29 m/s)	0.58 J

NdFeB products are prone to chipping – a collision with steel causes immediate chipping. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear eye protection when working with powerful specimens.

Water (riverbed)	1.68 kg (+0.21 kg buoyancy gain)	+14.5%

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

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

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

2. Efficiency vs thickness

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

3. Heat tolerance

*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) = 1.19

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 exceptionally strong cylindrical magnet, produced from modern NdFeB material, which, with dimensions of Ø8x15 mm, guarantees the highest energy density. The MW 8x15 / N38 model boasts high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.47 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating shields 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 14.45 N with a weight of only 5.65 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using epoxy glues. To ensure long-term durability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are suitable for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø8x15), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 8 mm and height 15 mm. The key parameter here is the lifting capacity amounting to approximately 1.47 kg (force ~14.45 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 15 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Pros and cons of neodymium magnets.

Advantages

Besides their remarkable pulling force, neodymium magnets offer the following advantages:

They do not lose magnetism, even after nearly ten years – the drop in lifting capacity is only ~1% (based on measurements),
They have excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
In other words, due to the reflective layer of silver, the element looks attractive,
They show high magnetic induction at the operating surface, making them more effective,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to modularity in designing and the capacity to adapt to individual projects,
Key role in electronics industry – they find application in data components, brushless drives, advanced medical instruments, and industrial machines.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

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.
Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Limited possibility of making threads in the magnet and complex shapes - recommended is a housing - magnetic holder.
Possible danger to health – tiny shards of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical when they are in the body.
Due to expensive raw materials, their price is relatively high,

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what it depends on?

Information about lifting capacity is the result of a measurement for the most favorable conditions, taking into account:

on a block made of structural steel, optimally conducting the magnetic field
whose transverse dimension equals approx. 10 mm
with a plane perfectly flat
without any insulating layer between the magnet and steel
during detachment in a direction vertical to the mounting surface
in stable room temperature

What influences lifting capacity in practice

Effective lifting capacity is influenced by specific conditions, including (from most important):

Air gap (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, rust or debris).
Direction of force – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

H&S for magnets

Allergic reactions

Some people suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Prolonged contact may cause a rash. We recommend use safety gloves.

Magnetic interference

Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.

Conscious usage

Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Dust explosion hazard

Powder produced during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Pinching danger

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!

Medical implants

Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.

Safe distance

Data protection: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).

Adults only

Neodymium magnets are not suitable for play. Eating several magnets can lead to them pinching intestinal walls, which poses a critical condition and necessitates urgent medical intervention.

Demagnetization risk

Avoid heat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).

Magnet fragility

Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
