Grip strength weakens drastically with every subsequent millimeter of distance. Keep in mind that even the smallest gap (e.g., dirt, varnish, veneer) noticeably diminishes the holding power. Magnetic products operate most effectively in perfect adhesion; distance kills the force. Observe how flashily the parameters plummet, when the magnet does not touch directly to the metal substrate. When designing the mounting, discard additional spacers.

The table below defines the estimated holding capacity necessary to start the slippage of the magnet down along a vertical metal surface (assuming standard friction). The holding force is relative to the gap size between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
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 pounds 5880.0 g / 57.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	3.92 kg / 8.64 pounds 3920.0 g / 38.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.96 kg / 4.32 pounds 1960.0 g / 19.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	9.80 kg / 21.61 pounds 9800.0 g / 96.1 N

When hanging a magnet on a vertical wall (e.g., a car body), it you can count on just about 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip mean that products slide down easier than they detach. Planning a hanger? 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 much lighter load. Using a rubber layer can effectively improve the result.

Table 4: Steel thickness (saturation) - sheet metal selection
MW 25x12 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	5%	0.98 kg / 2.16 pounds 980.0 g / 9.6 N
1 mm	13%	2.45 kg / 5.40 pounds 2450.0 g / 24.0 N
2 mm	25%	4.90 kg / 10.80 pounds 4900.0 g / 48.1 N
3 mm	38%	7.35 kg / 16.20 pounds 7350.0 g / 72.1 N
5 mm	63%	12.25 kg / 27.01 pounds 12250.0 g / 120.2 N
10 mm	100%	19.60 kg / 43.21 pounds 19600.0 g / 192.3 N
11 mm	100%	19.60 kg / 43.21 pounds 19600.0 g / 192.3 N
12 mm	100%	19.60 kg / 43.21 pounds 19600.0 g / 192.3 N

A too thin steel is unable to conduct the entire magnetic field, which squanders power of the holder. If you mount a strong magnet to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this magnet's potential, you need a suitably thick element of metal. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the holder works worse. We recommend selecting the steel dimension according to the table below.

Standard neodymium magnets lose parameters past the thermal threshold. Protect against heat – high temperature can permanently destroy this product. As the temperature rises, the magnet's capacity briefly lowers. Avoid using this product in hot environments exceeding its working range. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) are more susceptible to demagnetization sooner than taller cylinders. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and sheet setup. The setup of two magnets produces a massive flux and a further horizon of operation. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Remember that when bringing together two magnets, the collision energy is massive. The levitation is a bit weaker than the attraction, but still large.
*Field value between like poles reaches ~0 Gs at the midpoint between the magnets (due to field cancellation).
Attention: Calculations apply to friction force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (implants) - precautionary measures

Powerful magnet radiation is a real danger to electronics as well as medical implants. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Remember: the unseen radiation acts through matter and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Collisions (cracking risk) - warning
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

Magnetic elements are prone to chipping – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Impact energy can trigger coating fragments or injury to skin. Always hold the magnet during installation so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when handling with powerful specimens.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces 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) = 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.

This product is an extremely powerful cylinder magnet, composed of modern NdFeB material, which, with dimensions of Ø25x12 mm, guarantees the highest energy density. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it an excellent 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 European logistics center, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 192.25 N with a weight of only 44.18 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel 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 operational stability. If you need even stronger magnets in the same volume (Ø25x12), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø25x12 mm, which, at a weight of 44.18 g, makes it an element with impressive magnetic energy density. 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 protects the surface against oxidation, giving it an aesthetic, silvery shine.

This cylinder 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 and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They do not lose power, even during around ten years – the drop in power is only ~1% (theoretically),
Neodymium magnets are characterized by remarkably resistant to loss of magnetic properties caused by external interference,
A magnet with a smooth silver surface is more attractive,
The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
In view of the possibility of flexible shaping and customization to individualized requirements, NdFeB magnets can be created in a variety of shapes and sizes, which amplifies use scope,
Versatile presence in high-tech industry – they are used in mass storage devices, drive modules, medical equipment, as well as other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Disadvantages

What to avoid - cons of neodymium magnets: tips and applications.

To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Due to limitations in producing threads and complicated shapes in magnets, we recommend using casing - magnetic holder.
Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

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

Information about lifting capacity was determined for optimal configuration, including:

on a base made of structural steel, perfectly concentrating the magnetic flux
possessing a massiveness of at least 10 mm to avoid saturation
with an polished touching surface
under conditions of gap-free contact (surface-to-surface)
under vertical force vector (90-degree angle)
at conditions approx. 20°C

Practical aspects of lifting capacity – factors

In practice, the real power results from many variables, presented from the most important:

Gap 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.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Base massiveness – insufficiently thick steel does not accept the full field, causing part of the power to be wasted to the other side.
Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate decreases the holding force.

Warnings

Material brittleness

Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Warning for heart patients

Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Cards and drives

Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).

Power loss in heat

Watch the temperature. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.

Conscious usage

Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Keep away from children

Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.

Dust is flammable

Dust generated during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Keep away from electronics

Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Crushing risk

Danger of trauma: The pulling power is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Avoid contact if allergic

Certain individuals experience a sensitization to nickel, which is the standard coating for NdFeB magnets. Prolonged contact may cause dermatitis. We recommend wear protective gloves.
