Magnetic force drops sharply per each millimeter of gap. Note that even a microscopic distance (e.g., dirt, paint, rust) noticeably reduces the pull force. Magnetic products work optimally during direct contact; air break kills the force. See how flashily the load capacity drop, when the product does not adhere directly to the metal substrate. When planning the arrangement, discard redundant distances.

The following data defines the estimated holding capacity necessary to initiate the slippage of the magnet down against a upright steel wall (considering standard friction). The holding force is a function of the gap size between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 15x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.62 kg / 3.56 lbs 1617.0 g / 15.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.08 kg / 2.38 lbs 1078.0 g / 10.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.54 kg / 1.19 lbs 539.0 g / 5.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.70 kg / 5.94 lbs 2695.0 g / 26.4 N

When hanging a element on a upright surface (e.g., a fridge), it will maintain only approx. 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip cause that products move down easier than they pop off the substrate. Planning a vertical fastening? Note that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will slide down under a noticeably lighter load. Application of an anti-slip pad can drastically raise the stability.

5 mm	100%	5.39 kg / 11.88 lbs 5390.0 g / 52.9 N

11 mm	100%	5.39 kg / 11.88 lbs 5390.0 g / 52.9 N
12 mm	100%	5.39 kg / 11.88 lbs 5390.0 g / 52.9 N

A thin metal plate cannot absorb the full magnetic flux, which weakens actual performance of the magnet. Should you attach a powerful product to a too thin substrate, the field will pass right through and the attraction force will be weaker. To squeeze 100% of this neodymium's potential, you require a sufficiently solid element of steel. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the holder works worse. We advise picking the steel cross-section from these parameters.

Standard neodymium magnets irreversibly lose parameters above the temperature limit. Protect against heat – excessive heat can permanently demagnetize this magnet. With every degree above norm, the neodymium's force briefly lowers. Do not use this magnet close to ovens exceeding its working range. Ignoring the limit will lead to destruction of magnetism.

*Important note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) may lose charge permanently at lower temperatures than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a wider radius than a magnet and steel setup. The setup of two magnets produces a massive flux and a further horizon of performance. Designing a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is extreme. The repulsion force is slightly lower than the connection force, but still impressive.
*Flux density in repulsion mode drops to ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Attention: Figures apply to shear force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field is a large risk to electronics and pacemakers. These magnets generate a field that disrupts operation of digital equipment. Be aware: the unseen radiation passes through tissues and glass. Special caution must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Dynamics (kinetic energy) - collision effects
MW 15x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	29.27 km/h (8.13 m/s)	0.22 J
30 mm	49.81 km/h (13.84 m/s)	0.63 J
50 mm	64.30 km/h (17.86 m/s)	1.06 J
100 mm	90.93 km/h (25.26 m/s)	2.12 J

NdFeB products are delicate – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can trigger coating fragments or dangerous crushing to fingers. Always hold the magnet during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when working with large magnets.

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

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

1. Sliding resistance

*Warning: On a vertical surface, the magnet retains only approx. 20-30% of its max power.

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Temperature resistance

*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) = 0.44

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 offered product is an incredibly powerful cylindrical magnet, composed of durable NdFeB material, which, with dimensions of Ø15x5 mm, guarantees maximum efficiency. The MW 15x5 / N38 model 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. 5.39 kg), this product is available off-the-shelf 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, guaranteeing an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 52.83 N with a weight of only 6.63 g, this rod is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 15.1 mm) using two-component 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 durability 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 (Ø15x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø15x5 mm, which, at a weight of 6.63 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 5.39 kg (force ~52.83 N), which, with such defined dimensions, proves the high power of the NdFeB material. 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 5 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable 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 diametrically if your project requires it.

Strengths as well as weaknesses of neodymium magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They retain full power for almost 10 years – the drop is just ~1% (in theory),
Neodymium magnets are distinguished by highly resistant to loss of magnetic properties caused by external field sources,
A magnet with a smooth nickel surface is more attractive,
The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of accurate machining and adjusting to concrete applications,
Fundamental importance in future technologies – they are commonly used in hard drives, electric motors, diagnostic systems, also modern systems.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Cons

Problematic aspects of neodymium magnets and ways of using them

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated shapes.
Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these devices are able to disrupt the diagnostic process medical after entering the body.
With mass production the cost of neodymium magnets is a challenge,

Lifting parameters

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

The specified lifting capacity refers to the peak performance, measured under laboratory conditions, meaning:

with the application of a sheet made of special test steel, ensuring full magnetic saturation
possessing a massiveness of at least 10 mm to ensure full flux closure
characterized by even structure
under conditions of ideal adhesion (metal-to-metal)
during detachment in a direction vertical to the plane
at standard ambient temperature

Practical lifting capacity: influencing factors

Effective lifting capacity is influenced by working environment parameters, including (from priority):

Distance – the presence of any layer (rust, dirt, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.

Safety rules for work with neodymium magnets

Allergy Warning

A percentage of the population suffer from a contact allergy to Ni, which is the standard coating for NdFeB magnets. Extended handling can result in an allergic reaction. We suggest use safety gloves.

Combustion hazard

Powder created during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Heat warning

Do not overheat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Serious injuries

Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Safe operation

Handle with care. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.

Electronic devices

Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).

Implant safety

Warning for patients: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.

This is not a toy

NdFeB magnets are not suitable for play. Eating a few magnets may result in them pinching intestinal walls, which poses a critical condition and requires urgent medical intervention.

Risk of cracking

Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets will cause them breaking into small pieces.

Impact on smartphones

Be aware: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your mobile, device, and navigation systems.
