Magnetic force decreases drastically with every mm of gap. Note that even a microscopic distance (e.g., contamination, paint, veneer) strongly weakens the grip. Magnetic products operate optimally during direct contact; gap nullifies the power. See how quickly the parameters plummet, when the magnet does not adhere flatly to the steel surface. When planning the mounting, discard unnecessary gaps.

The following data indicates the theoretical holding capacity sufficient to start the sliding of the magnet downwards on a upright steel plate (considering typical friction). This parameter is a function of the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 38x3.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.53 kg / 3.37 lbs 1527.0 g / 15.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.02 kg / 2.24 lbs 1018.0 g / 10.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.51 kg / 1.12 lbs 509.0 g / 5.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.55 kg / 5.61 lbs 2545.0 g / 25.0 N

When hanging a element on a upright wall (e.g., a fridge), it will maintain just approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip cause that holders move down easier than they detach. Planning a wall mount? Note that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the magnet will give way down under a significantly smaller load. Utilizing a rubberized coating can significantly raise the stability.

12 mm	100%	5.09 kg / 11.22 lbs 5090.0 g / 49.9 N

A too thin steel is incapable of absorb the full magnetic flux, which wastes potential of the magnet. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To squeeze full efficiency of this neodymium's potential, you require a sufficiently solid element of metal. The saturation effect causes that on thin elements (e.g., thin profiles), the magnet shows lower pull force. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products change their properties strength past the thermal threshold. Avoid high temperatures – high temperature can irreversibly demagnetize this product. As the temperature rises, the magnet's power briefly decreases. Avoid using this product close to ovens exceeding its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Thin magnets (pancake types) risk losing magnetic properties at lower temperatures than long magnets. Red status 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 combination. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Planning to create a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is massive. The levitation is marginally weaker than the connection force, but still significant.
*Field value between like poles is approximately ~0 Gs in the exact middle between the magnets (due to field cancellation).
Note: Results refer to friction force of two matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a serious hazard to electronics as well as pacemakers. These neodymiums generate a field that destroys function of digital equipment. Remember: the invisible magnetic field acts through matter and glass. Exceptional care must be exercised by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - warning

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	16.10 km/h (4.47 m/s)	0.30 J

50 mm	29.52 km/h (8.20 m/s)	1.00 J
100 mm	41.70 km/h (11.58 m/s)	2.00 J

Neodymium magnets are very brittle – a collision with steel causes immediate chipping. Control the attraction moment – a neodymium left loose becomes dangerous. Kinetic force can trigger coating fragments or injury to fingers. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Use safety goggles when handling with large magnets.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Shear force

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

2. Efficiency vs thickness

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

3. Power loss vs temp

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.14

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 presented product is an exceptionally strong cylinder magnet, produced from durable NdFeB material, which, with dimensions of Ø38x3.5 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 5.09 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 49.91 N with a weight of only 29.77 g, this rod is indispensable in electronics and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 38.1 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 durability of the connection.

Magnets N38 are strong enough for the majority of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø38x3.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø38x3.5 mm, which, at a weight of 29.77 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 5.09 kg (force ~49.91 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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 38 mm. 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.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Advantages

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

They retain magnetic properties for almost 10 years – the loss is just ~1% (based on simulations),
They possess excellent resistance to magnetic field loss as a result of external magnetic sources,
The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to look better,
They show high magnetic induction at the operating surface, making them more effective,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Thanks to freedom in shaping and the capacity to customize to individual projects,
Significant place in future technologies – they are utilized in magnetic memories, electromotive mechanisms, medical devices, as well as technologically advanced constructions.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Limited possibility of making threads in the magnet and complicated forms - recommended is a housing - magnet mounting.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small components of these magnets can be problematic in diagnostics medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what affects it?

Breakaway force is the result of a measurement for the most favorable conditions, including:

on a block made of structural steel, effectively closing the magnetic flux
whose transverse dimension is min. 10 mm
with a plane perfectly flat
with direct contact (no paint)
under vertical application of breakaway force (90-degree angle)
at temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

In practice, the actual lifting capacity depends on several key aspects, ranked from most significant:

Air gap (betwixt the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Warnings

Medical implants

People with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can stop the functioning of the life-saving device.

Fire risk

Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Heat sensitivity

Watch the temperature. Exposing the magnet to high heat will destroy its magnetic structure and strength.

Nickel coating and allergies

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease working with magnets and wear gloves.

Pinching danger

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

Phone sensors

GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Conscious usage

Handle magnets with awareness. Their huge power can shock even experienced users. Plan your moves and respect their power.

Choking Hazard

Strictly keep magnets away from children. Ingestion danger is high, and the consequences of magnets connecting inside the body are very dangerous.

Material brittleness

Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Protect data

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