Pulling power drops sharply with every mm of gap. Remember that even a very thin break (e.g., contamination, paint, veneer) significantly diminishes the holding power. Neodymiums operate strongest during direct contact; gap drastically cuts the power. Analyze how rapidly the load capacity drop, when the magnet does not adhere directly to the metal substrate. When designing the mounting, eliminate additional spacers.

The table below presents the estimated shear load needed to start the slippage of the magnet vertically against a upright steel plate (assuming standard friction coefficient). This parameter is relative to the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 5x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.14 kg / 0.30 pounds 135.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 pounds 90.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 pounds 45.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.50 pounds 225.0 g / 2.2 N

When hanging a magnet on a vertical plane (e.g., a fridge), it you can count on only about 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip influence the fact that magnets move down easier than they pull off. Designing a wall mount? Remember that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slip down under a significantly smaller load. Application of an anti-slip layer can significantly improve the result.

12 mm	100%	0.45 kg / 0.99 pounds 450.0 g / 4.4 N

A thin metal plate is not enough to take in the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a too thin substrate, the field will pass right through and the holding will be smaller. To utilize the maximum of this neodymium's power, you require a sufficiently solid element of steel. The saturation effect means that on sheet metal structures (e.g., thin profiles), the magnet shows lower pull force. We advise picking the steel thickness according to the table below.

Classic neodymiums irreversibly lose strength above the temperature limit. Avoid high temperatures – excessive heat can permanently demagnetize this product. As the temperature rises, the magnet's force temporarily drops. Refrain from using this magnet near heat sources exceeding its operating temperature limit. Too high temperature will lead to destruction of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and steel setup. The setup of two magnets generates a stronger field and a further horizon of operation. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the impact force is huge. The repulsion force is slightly lower than the connection force, but still significant.
*Flux density for N-N configuration reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
* Estimates demonstrate sliding force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a large risk to electronics as well as medical implants. These neodymiums generate a field that disrupts operation of digital equipment. Remember: the unseen radiation passes through tissues and glass. Exceptional care must be taken by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

NdFeB products are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can trigger coating fragments or dangerous crushing to fingers. 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 ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

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. Vertical hold

*Note: On a vertical surface, the magnet holds merely ~20% of its max power.

2. Steel saturation

*Thin steel (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) = 1.59

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 a very strong cylinder magnet, made from advanced NdFeB material, which, at dimensions of Ø5x30 mm, guarantees the highest energy density. The MW 5x30 / N38 model boasts a tolerance of ±0.1mm and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.45 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick 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.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 4.40 N with a weight of only 4.42 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need even stronger magnets in the same volume (Ø5x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 5 mm and height 30 mm. The key parameter here is the holding force amounting to approximately 0.45 kg (force ~4.40 N), which, with such defined dimensions, proves the high grade of the NdFeB material. 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. 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 neodymium magnets.

Advantages

Besides their exceptional magnetic power, neodymium magnets offer the following advantages:

They have stable power, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
Neodymium magnets are characterized by highly resistant to demagnetization caused by external interference,
By applying a smooth coating of nickel, the element acquires an nice look,
Magnets exhibit impressive magnetic induction on the active area,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of detailed creating and adjusting to specific requirements,
Significant place in future technologies – they are utilized in magnetic memories, electric motors, advanced medical instruments, and complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions

Weaknesses

Disadvantages of NdFeB magnets:

At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose their force 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
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
We recommend casing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated forms.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these devices are able to be problematic in diagnostics medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

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

Magnet power was defined for ideal contact conditions, including:

using a plate made of high-permeability steel, functioning as a magnetic yoke
whose thickness equals approx. 10 mm
with a surface free of scratches
with direct contact (no coatings)
during pulling in a direction vertical to the plane
at standard ambient temperature

Determinants of practical lifting force of a magnet

Please note that the working load may be lower influenced by elements below, in order of importance:

Air gap (betwixt the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or debris).
Pull-off angle – 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.
Steel thickness – too thin steel does not close the flux, causing part of the flux to be wasted to the other side.
Material type – the best choice is pure iron steel. Cast iron may attract less.
Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.

Warnings

Pacemakers

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

Fire risk

Powder generated during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Metal Allergy

Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease handling magnets and use protective gear.

Pinching danger

Large magnets can break fingers in a fraction of a second. Do not place your hand between two strong magnets.

Powerful field

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Keep away from electronics

An intense magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid damaging the sensors.

Magnetic media

Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.

Material brittleness

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Heat warning

Do not overheat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

This is not a toy

Neodymium magnets are not suitable for play. Eating several magnets may result in them pinching intestinal walls, which poses a direct threat to life and requires urgent medical intervention.
