Pulling power drops sharply with every mm of spacing. Keep in mind that even a very thin break (e.g., dirt, varnish, veneer) significantly weakens the grip. Neodymiums hold optimally in perfect adhesion; gap kills the power. Notice how rapidly the pull force drop, when the magnet does not adhere directly to the steel surface. When designing the mounting, avoid redundant distances.

The table below shows the theoretical weight limit sufficient to start the downward movement of the magnet down along a vertical metal surface (assuming standard friction coefficient). This value varies with the gap size between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.79 kg / 1.73 LBS 786.0 g / 7.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.52 kg / 1.16 LBS 524.0 g / 5.1 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.31 kg / 2.89 LBS 1310.0 g / 12.9 N

When mounting a magnet on a upright plane (e.g., a car body), it will only hold only approx. 20%-30% of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that products move down easier than they pop off the substrate. Planning a vertical fastening? Consider that the shear force is significantly lower than the maximum static pull force. On a slippery surface, the magnet will slide down under a noticeably lighter load. Utilizing a rubberized pad can drastically improve the result.

A thin metal plate cannot take in the full magnetic flux, which weakens actual performance of the holder. If you mount a strong magnet to a too thin substrate, the field will pass right through and the attraction force will be weaker. To achieve the maximum of this neodymium's power, you need a suitably thick backing of metal. The material oversaturation causes that on thin elements (e.g., thin profiles), the holder works worse. We suggest choosing the steel thickness from these parameters.

Ordinary NdFeB products lose power after exceeding the maximum temperature. Avoid high temperatures – heat can irreversibly destroy this magnet. With increasing heat, the neodymium's force temporarily decreases. Do not use this magnet in hot environments exceeding its working range. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a magnet and steel combination. The setup of magnet-to-magnet produces a massive flux and a wider radius of operation. Want to build a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is huge. The levitation is slightly lower than the connection force, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Attention: Figures apply to friction force of dual same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Hazards (implants) - precautionary measures
MW 12x50 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	11.0 cm
Hearing aid	10 Gs (1.0 mT)	8.5 cm

A strong magnetic field poses a serious hazard to IT equipment and pacemakers. These NdFeB products generate a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, car keys, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - collision effects
MW 12x50 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	8.02 km/h (2.23 m/s)	0.11 J
30 mm	13.73 km/h (3.81 m/s)	0.31 J
50 mm	17.73 km/h (4.92 m/s)	0.51 J
100 mm	25.07 km/h (6.96 m/s)	1.03 J

NdFeB products are delicate – a strong collision with metal can result in shattering. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or painful pinches to fingers. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when handling with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

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

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

2. Steel thickness impact

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

3. Power loss vs temp

*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) = 1.49

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 an incredibly powerful cylinder magnet, made from durable NdFeB material, which, at dimensions of Ø12x50 mm, guarantees optimal power. The MW 12x50 / N38 component features an accuracy of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 2.62 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 25.73 N with a weight of only 42.41 g, this rod is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 12.1 mm) using epoxy glues. To ensure stability in industry, anaerobic resins 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 the strongest magnets in the same volume (Ø12x50), 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 12 mm and height 50 mm. The value of 25.73 N means that the magnet is capable of holding a weight many times exceeding its own mass of 42.41 g. 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 12 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 as well as cons of Nd₂Fe₁₄B magnets.

Advantages

Apart from their consistent holding force, neodymium magnets have these key benefits:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
They retain their magnetic properties even under external field action,
A magnet with a smooth gold surface is more attractive,
Magnetic induction on the working part of the magnet remains very high,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Due to the possibility of accurate shaping and adaptation to unique solutions, magnetic components can be created in a variety of forms and dimensions, which increases their versatility,
Significant place in advanced technology sectors – they are used in hard drives, brushless drives, medical devices, also technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in small systems

Limitations

Disadvantages of neodymium magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in realizing threads and complicated shapes in magnets, we propose using cover - magnetic holder.
Potential hazard to health – tiny shards of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to complicate diagnosis medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Best holding force of the magnet in ideal parameters – what it depends on?

Magnet power was determined for optimal configuration, including:

on a block made of mild steel, optimally conducting the magnetic field
possessing a massiveness of minimum 10 mm to avoid saturation
with a plane free of scratches
with total lack of distance (no paint)
during detachment in a direction vertical to the plane
at temperature room level

Determinants of lifting force in real conditions

In practice, the actual holding force is determined by several key aspects, listed from crucial:

Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Material type – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
Plate texture – ground elements guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the load capacity.

Warnings

Allergic reactions

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.

Phone sensors

GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.

Magnetic media

Avoid bringing magnets near a purse, computer, or screen. The magnetic field can destroy these devices and erase data from cards.

Operating temperature

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Immense force

Handle with care. Rare earth magnets attract from a distance and snap with massive power, often quicker than you can move away.

Physical harm

Big blocks can smash fingers in a fraction of a second. Never place your hand betwixt two strong magnets.

Combustion hazard

Dust produced during machining of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Fragile material

Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them cracking into small pieces.

Adults only

NdFeB magnets are not intended for children. Eating several magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires immediate surgery.

Life threat

Patients with a ICD must maintain an safe separation from magnets. The magnetism can interfere with the operation of the implant.
