Magnetic force decreases drastically per each millimeter of spacing. Note that even a microscopic distance (e.g., contamination, paint, veneer) noticeably weakens the grip. Magnets operate optimally during direct contact; distance weakens the power. Observe how flashily the parameters plummet, when the product does not adhere tightly to the metal substrate. When designing the arrangement, discard unnecessary gaps.

The following data shows the estimated weight limit needed to cause the downward movement of the magnet downwards against a upright metal surface (assuming standard friction coefficient). This parameter is relative to the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 29.9x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	6.45 kg / 14.22 pounds 6450.0 g / 63.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.30 kg / 9.48 pounds 4300.0 g / 42.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.15 kg / 4.74 pounds 2150.0 g / 21.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	10.75 kg / 23.70 pounds 10750.0 g / 105.5 N

When placing a magnet on a vertical wall (e.g., a fridge), it will maintain barely approx. 1/5 of nominal attraction strength. Gravity and a weak degree of grip mean that magnets slide down faster than they pop off the substrate. Designing a hanger? Note that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a much lighter weight. Using a rubber coating can drastically raise the stability.

12 mm	100%	21.50 kg / 47.40 pounds 21500.0 g / 210.9 N

A too thin steel is unable to absorb the entire magnetic field, which weakens actual performance of the holder. If you install a neodymium to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To utilize the maximum of this magnet's power, you need a suitably thick piece of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel dimension from these parameters.

Classic neodymiums change their properties strength past the thermal threshold. Protect against heat – heat can irreversibly destroy this magnet. With increasing heat, the neodymium's power briefly decreases. Do not use this magnet close to ovens exceeding its operating temperature limit. Exceeding the critical threshold will cause permanent loss of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) risk losing magnetic properties sooner than taller cylinders. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a wider radius than a magnet and sheet combination. The setup of magnet-to-magnet generates a stronger field and a larger range of operation. Want to build a strong closure? Apply two magnets instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the pinch force is massive. The levitation is a bit weaker than the attraction, but still large.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Note: Estimates demonstrate shear force of two same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to electronic devices as well as pacemakers. These neodymiums produce a field that destroys function of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and housings. Special caution must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are delicate – a collision with steel can result in shattering. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or painful pinches to skin. Be sure to control the product during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when playing with powerful specimens.

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

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

1. Sliding resistance

*Note: On a vertical wall, the magnet holds merely approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

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

3. Temperature resistance

*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) = 0.44

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 extremely powerful cylinder magnet, composed of modern NdFeB material, which, at dimensions of Ø29.9x10 mm, guarantees the highest energy density. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 21.50 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 210.90 N with a weight of only 52.66 g, this rod is indispensable in electronics and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable 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 (Ø29.9x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 29.9 mm and height 10 mm. The value of 210.90 N means that the magnet is capable of holding a weight many times exceeding its own mass of 52.66 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 10 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 diametrically if your project requires it.

Pros and cons of rare earth magnets.

Strengths

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

They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
They have excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
In other words, due to the shiny layer of gold, the element gains a professional look,
The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
Possibility of accurate forming as well as optimizing to specific needs,
Significant place in modern industrial fields – they are utilized in mass storage devices, electric drive systems, diagnostic systems, and other advanced devices.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Disadvantages

Drawbacks and weaknesses of neodymium magnets: application proposals

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding 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 casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to disrupt the diagnostic process medical when they are in the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Maximum holding power of the magnet – what it depends on?

Holding force of 21.50 kg is a result of laboratory testing conducted under specific, ideal conditions:

on a base made of mild steel, optimally conducting the magnetic field
whose transverse dimension is min. 10 mm
with a surface free of scratches
with zero gap (no impurities)
for force acting at a right angle (in the magnet axis)
at standard ambient temperature

Practical aspects of lifting capacity – factors

Holding efficiency is influenced by specific conditions, such as (from priority):

Gap (betwixt the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with NdFeB magnets

Danger to pacemakers

For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to work with the magnets.

Thermal limits

Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).

Keep away from children

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

Hand protection

Pinching hazard: The pulling power is so immense that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Respect the power

Handle magnets consciously. Their huge power can shock even professionals. Stay alert and do not underestimate their power.

Skin irritation risks

It is widely known that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact and opt for versions in plastic housing.

Beware of splinters

Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Precision electronics

Remember: rare earth magnets produce a field that disrupts sensitive sensors. Keep a separation from your phone, tablet, and GPS.

Combustion hazard

Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

Keep away from computers

Intense magnetic fields can destroy records on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
