Pulling power drops significantly per each millimeter of gap. Remember that even a very thin break (e.g., contamination, paint, dust) strongly weakens the grip. Magnetic products operate optimally at the point of direct contact; distance weakens the power. Notice how quickly the pull force plummet, when the product does not touch directly to the metal substrate. When planning the arrangement, discard redundant distances.

The following data indicates the theoretical force required to start the downward movement of the magnet down along a upright steel wall (assuming standard friction coefficient). This value varies with the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 5x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.24 kg / 0.52 LBS 237.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.16 kg / 0.35 LBS 158.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 LBS 79.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.40 kg / 0.87 LBS 395.0 g / 3.9 N

When mounting a holder on a vertical wall (e.g., a board), it will maintain just approx. 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip cause that products slip easier than they detach. Planning a hanger? Consider that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the element will slide down under a significantly smaller load. Utilizing a rubberized layer can significantly increase the grip.

12 mm	100%	0.79 kg / 1.74 LBS 790.0 g / 7.7 N

A thin sheet is unable to focus the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a too thin substrate, the field will pass right through and the pull force will drop sharply. To achieve 100% of this magnet's power, you need a suitably thick backing of metal. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the product shows lower pull force. We advise picking the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Protect against heat – excessive heat can permanently destroy this product. As the temperature rises, the neodymium's force temporarily drops. Do not use this magnet near heat sources higher than its working range. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than taller cylinders. Warning indicator in the table indicates permanent field degradation for this particular item.

Two strong neodymiums interact from a wider radius than a neodymium and metal setup. Such a system of two magnets creates a more powerful interaction and a wider radius of operation. Designing a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the impact force is extreme. The repulsion force is marginally weaker than the attraction, but still large.
*Flux density for N-N configuration drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Note: Calculations demonstrate shear force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to electronics and medical implants. These magnets produce a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field acts through matter and plastic. Special caution must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - warning

Magnetic elements are delicate – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can trigger coating fragments or painful pinches to skin. 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 safety glasses when handling with powerful specimens.

Rust risk: 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. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Warning: On a vertical surface, the magnet holds merely a fraction of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely limits 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) = 0.89

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.

This product is an incredibly powerful rod magnet, composed of advanced NdFeB material, which, with dimensions of Ø5x5 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 0.79 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 7.76 N with a weight of only 0.74 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability 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 popular standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø5x5), 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 5 mm and height 5 mm. The value of 7.76 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.74 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 5 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 through the diameter if your project requires it.

Strengths and weaknesses of neodymium magnets.

Strengths

Apart from their notable power, neodymium magnets have these key benefits:

They retain full power for almost 10 years – the loss is just ~1% (according to analyses),
They have excellent resistance to magnetism drop when exposed to external magnetic sources,
The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Possibility of accurate shaping as well as adapting to concrete applications,
Fundamental importance in innovative solutions – they serve a role in computer drives, electromotive mechanisms, diagnostic systems, and industrial machines.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Drawbacks and weaknesses of neodymium magnets and proposals for their use:

At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic mount, due to difficulties in producing threads inside the magnet and complicated shapes.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small components of these products can complicate diagnosis medical in case of swallowing.
Due to neodymium price, their price is higher than average,

Pull force analysis

Detachment force of the magnet in optimal conditions – what it depends on?

Information about lifting capacity was determined for the most favorable conditions, assuming:

on a base made of structural steel, perfectly concentrating the magnetic field
possessing a massiveness of minimum 10 mm to ensure full flux closure
characterized by smoothness
under conditions of no distance (surface-to-surface)
during pulling in a direction perpendicular to the plane
at temperature room level

Practical aspects of lifting capacity – factors

Real force impacted by working environment parameters, such as (from priority):

Clearance – existence of any layer (paint, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
Material type – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the holding force.

Warnings

Do not give to children

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

Material brittleness

NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them breaking into shards.

Bone fractures

Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.

Keep away from computers

Equipment safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).

Power loss in heat

Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Handling rules

Handle with care. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can move away.

Keep away from electronics

GPS units and mobile phones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Fire warning

Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.

Medical interference

For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Allergy Warning

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease handling magnets and wear gloves.

Warning! More info about hazards in the article: Safety of working with magnets.
