Pulling power drops drastically per each millimeter of gap. Keep in mind that even the smallest gap (e.g., dirt, paint, dust) significantly reduces the pull force. Neodymiums hold optimally during direct contact; air break weakens the power. Analyze how flashily the load capacity fall, when the product does not touch flatly to the metal substrate. When designing the assembly, discard additional spacers.

The following data indicates the approximate weight limit needed to start the sliding of the magnet downwards against a upright steel wall (assuming typical friction coefficient). This value is a function of the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MW 25x12 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	5.88 kg / 12.96 lbs 5880.0 g / 57.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	3.92 kg / 8.64 lbs 3920.0 g / 38.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.96 kg / 4.32 lbs 1960.0 g / 19.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	9.80 kg / 21.61 lbs 9800.0 g / 96.1 N

When mounting a magnet on a vertical wall (e.g., a fridge), it will only hold just about 20%-30% of its nominal power. Gravitational force and a weak degree of grip mean that magnets move down faster than they detach. Planning a hanger? Consider that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the magnet will slip down under a noticeably lighter load. Utilizing a rubberized layer can effectively improve the result.

A too thin steel is incapable of focus the full magnetic flux, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the magnetism will pass right through and the holding will be smaller. To squeeze the maximum of this magnet's power, you require a sufficiently solid backing of steel. The saturation effect causes that on thin elements (e.g., thin profiles), the magnet shows lower pull force. We advise picking the steel cross-section according to the table below.

Standard neodymium magnets lose strength above the temperature limit. Avoid high temperatures – excessive heat can permanently demagnetize this magnet. With increasing heat, the neodymium's force momentarily lowers. Avoid using this magnet close to heaters exceeding its safe range. Too high temperature will result in destruction of magnetic properties.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) may lose charge permanently sooner than taller cylinders. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two magnets interact from a significantly greater distance than a magnet and steel setup. Such a system of two magnets produces a massive flux and a larger range of performance. Designing a strong closure? Use a pair of magnets instead of one magnet and a steel. Be careful that when attracting two neodymiums, the impact force is massive. The repulsion force is a bit weaker than the attraction, but still significant.
*The magnetic induction for N-N configuration drops to ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
* Results show sliding force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - precautionary measures

Powerful magnet radiation is a serious hazard to electronic devices and medical implants. These neodymiums generate a flux that prevents correct functioning of digital equipment. Notice: the invisible magnetic field acts through matter and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - collision effects
MW 25x12 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	22.84 km/h (6.35 m/s)	0.89 J
30 mm	36.85 km/h (10.24 m/s)	2.31 J
50 mm	47.51 km/h (13.20 m/s)	3.85 J
100 mm	67.17 km/h (18.66 m/s)	7.69 J

Neodymium magnets are very brittle – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or dangerous crushing to fingers. Always hold the magnet during installation 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 magnet. Use safety goggles when handling with large magnets.

Rust risk: 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. Shear force

*Caution: On a vertical surface, the magnet retains merely approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.57

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 offered product is an incredibly powerful cylinder magnet, produced from modern NdFeB material, which, with dimensions of Ø25x12 mm, guarantees the highest energy density. The MW 25x12 / N38 component features a tolerance of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 19.60 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the high power of 192.25 N with a weight of only 44.18 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 25.1 mm) using two-component 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 high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø25x12), 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 25 mm and height 12 mm. The value of 192.25 N means that the magnet is capable of holding a weight many times exceeding its own mass of 44.18 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 12 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 through the diameter if your project requires it.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

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

They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
They show high resistance to demagnetization induced by external magnetic fields,
By covering with a smooth layer of silver, the element gains an professional look,
Magnets exhibit extremely high magnetic induction on the outer layer,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of exact creating and adjusting to individual needs,
Key role in modern technologies – they are commonly used in magnetic memories, electromotive mechanisms, advanced medical instruments, and complex engineering applications.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Cons of neodymium magnets and proposals for their use:

At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited ability of creating threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Furthermore, small components of these magnets are able to complicate diagnosis medical in case of swallowing.
Due to complex production process, their price exceeds standard values,

Pull force analysis

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

The specified lifting capacity refers to the peak performance, obtained under laboratory conditions, meaning:

using a plate made of high-permeability steel, functioning as a ideal flux conductor
whose thickness equals approx. 10 mm
characterized by smoothness
under conditions of gap-free contact (metal-to-metal)
during pulling in a direction perpendicular to the mounting surface
in temp. approx. 20°C

Key elements affecting lifting force

In practice, the actual holding force results from several key aspects, ranked from crucial:

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
Load vector – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be escaped into the air.
Material type – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
Surface finish – full contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.

Warnings

Compass and GPS

Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.

Operating temperature

Do not overheat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Fire warning

Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

This is not a toy

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

Conscious usage

Be careful. Neodymium magnets act from a distance and snap with huge force, often quicker than you can move away.

Risk of cracking

NdFeB magnets are ceramic materials, meaning they are very brittle. Impact of two magnets leads to them cracking into small pieces.

Protect data

Device Safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Medical implants

Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Skin irritation risks

Certain individuals have a sensitization to Ni, which is the standard coating for neodymium magnets. Extended handling might lead to an allergic reaction. It is best to wear protective gloves.

Hand protection

Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
