Magnetic force drops sharply per each millimeter of distance. Note that every additional insulation layer (e.g., dirt, varnish, rust) noticeably diminishes the holding power. Magnetic products work most effectively in perfect adhesion; distance weakens the power. Analyze how rapidly the pull force fall, when the magnet does not touch flatly to the metal substrate. When planning the mounting, eliminate unnecessary gaps.

The following data defines the theoretical force needed to start the sliding of the magnet downwards along a upright steel wall (assuming standard friction coefficient). This parameter is relative to the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 8x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.61 kg / 1.34 lbs 609.0 g / 6.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.41 kg / 0.90 lbs 406.0 g / 4.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.20 kg / 0.45 lbs 203.0 g / 2.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.02 kg / 2.24 lbs 1015.0 g / 10.0 N

When mounting a holder on a upright wall (e.g., a board), it will only hold barely about 20%-30% of nominal attraction strength. Gravitational force as well as a low friction coefficient mean that magnets slide down easier than they detach. Designing a wall mount? Note that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the holder will slide down under a significantly smaller load. Utilizing a rubberized coating can drastically increase the grip.

A thin metal plate cannot take in the full magnetic flux, which squanders power of the magnet. Should you mount a strong magnet to a weak sheet, the field will pass right through and the holding will be smaller. To utilize 100% of this neodymium's potential, you need a suitably thick backing of metal. The material oversaturation means that on sheet metal structures (e.g., car bodies), the product shows lower pull force. We suggest choosing the steel cross-section based on the following data.

Ordinary NdFeB products irreversibly lose parameters above the temperature limit. Protect against heat – heat can irreversibly destroy this magnet. As the temperature rises, the magnet's power temporarily lowers. Refrain from using this magnet near heat sources exceeding its working range. Exceeding the critical threshold will cause permanent loss of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) may lose charge permanently at lower temperatures than long magnets. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a much further distance than a magnet and sheet setup. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of performance. Designing a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the pinch force is huge. The repulsion force is marginally weaker than the attraction, but still impressive.
*Field value for N-N configuration reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Important: Results show shear force of two same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a large risk to electronic devices as well as medical implants. These magnets generate a flux that destroys function of digital equipment. Notice: the invisible magnetic field acts through matter and housings. Special caution must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Watch the impact speed – a neodymium left loose speeds with massive force. Impact energy can trigger coating fragments or painful pinches to fingers. Hold the magnet firmly during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when handling with large magnets.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Warning: On a vertical surface, the magnet retains just a fraction of its max power.

2. Steel thickness impact

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.89

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.

This product is a very strong cylindrical magnet, composed of advanced NdFeB material, which, with dimensions of Ø8x8 mm, guarantees optimal power. The MW 8x8 / N38 component is characterized by high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 2.03 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 19.92 N with a weight of only 3.02 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. 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.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø8x8), 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 8 mm. The key parameter here is the holding force amounting to approximately 2.03 kg (force ~19.92 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 oxidation, 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 8 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.

Pros and cons of Nd₂Fe₁₄B magnets.

Advantages

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

They have stable power, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
They feature excellent resistance to weakening of magnetic properties due to external magnetic sources,
A magnet with a smooth gold surface looks better,
They are known for high magnetic induction at the operating surface, which increases their power,
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...
Thanks to modularity in designing and the ability to modify to specific needs,
Key role in electronics industry – they are utilized in mass storage devices, electric motors, diagnostic systems, also other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

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

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets lose 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 durability even at temperatures up to 230°C
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
Potential hazard resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting capacity of the magnet – what affects it?

Information about lifting capacity was defined for ideal contact conditions, including:

using a sheet made of high-permeability steel, acting as a circuit closing element
whose transverse dimension equals approx. 10 mm
with an ground touching surface
under conditions of no distance (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
at temperature room level

Magnet lifting force in use – key factors

Please note that the magnet holding may be lower subject to elements below, in order of importance:

Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be escaped to the other side.
Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and holding force.
Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.

Precautions when working with NdFeB magnets

Pinching danger

Large magnets can break fingers in a fraction of a second. Never place your hand betwixt two strong magnets.

Life threat

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Do not underestimate power

Exercise caution. Neodymium magnets act from a long distance and connect with massive power, often faster than you can move away.

Product not for children

NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates urgent medical intervention.

Heat sensitivity

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

Warning for allergy sufferers

Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, avoid direct skin contact or opt for coated magnets.

Keep away from electronics

Note: neodymium magnets generate a field that confuses sensitive sensors. Keep a separation from your mobile, tablet, and GPS.

Fire warning

Machining of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Magnets are brittle

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

Data carriers

Equipment safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
