Grip strength decreases sharply with every subsequent millimeter of gap. Keep in mind that even a very thin break (e.g., dirt, varnish, dust) noticeably diminishes the holding power. Magnetic products work most effectively in perfect adhesion; air break nullifies the power. See how quickly the pull force plummet, when the magnet does not touch tightly to the metal substrate. When calculating the mounting, avoid redundant distances.

The following data presents the theoretical shear load necessary to start the sliding of the magnet vertically on a upright metal surface (considering typical friction coefficient). This parameter is relative to the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 15x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.86 kg / 1.90 lbs 861.0 g / 8.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.57 kg / 1.27 lbs 574.0 g / 5.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.29 kg / 0.63 lbs 287.0 g / 2.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.44 kg / 3.16 lbs 1435.0 g / 14.1 N

When placing a holder on a upright wall (e.g., a board), it will only hold barely about 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient cause that holders slip faster than they detach. Designing a vertical fastening? Consider that the shear force is much weaker than the maximum static pull force. On a smooth steel, the element will slip down under a significantly smaller weight. Application of an anti-slip layer can effectively increase the grip.

12 mm	100%	2.87 kg / 6.33 lbs 2870.0 g / 28.2 N

A thin metal plate is incapable of absorb the entire magnetic field, which squanders power of the holder. If you install a neodymium to a too thin substrate, the magnetism will pass right through and the attraction force will be weaker. To utilize full efficiency of this neodymium's potential, you need a suitably thick element of steel. The saturation effect means that on thin elements (e.g., appliance housings), the magnet shows lower pull force. We suggest choosing the steel thickness from these parameters.

Ordinary NdFeB products irreversibly lose parameters after exceeding the maximum temperature. Avoid high temperatures – heat can irreversibly damage this magnet. With every degree above norm, the magnet's force temporarily lowers. Avoid using this product in hot environments exceeding its operating temperature limit. Too high temperature will lead to irreversible degradation of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) are more susceptible to demagnetization under lower heat stress compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and sheet combination. The connection of magnet-to-magnet generates a stronger field and a further horizon of operation. Planning to create a powerful holder? Apply two magnets instead of one magnet and a steel. Remember that when bringing together two magnets, the pinch force is huge. The repulsion force is marginally weaker than the connection force, but still large.
*Flux density in repulsion mode is approximately ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Important: Results show friction force of two same neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a large risk to IT equipment as well as medical implants. These neodymiums generate a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field acts through matter and plastic. Special caution must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - warning
MW 15x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	27.62 km/h (7.67 m/s)	0.12 J

50 mm	60.56 km/h (16.82 m/s)	0.56 J
100 mm	85.64 km/h (23.79 m/s)	1.13 J

Magnetic elements are very brittle – a collision with steel causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or painful pinches to skin. Hold the magnet firmly during mounting so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the magnet. Use safety goggles when playing with large magnets.

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. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Note: On a vertical surface, 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 weakens the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.29

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 presented product is a very strong rod magnet, produced from durable NdFeB material, which, with dimensions of Ø15x3 mm, guarantees the highest energy density. This specific item features high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 2.87 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 28.14 N with a weight of only 3.98 g, this rod is indispensable in electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 15.1 mm) using two-component epoxy glues. 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 strong enough for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø15x3), 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 Ø15x3 mm, which, at a weight of 3.98 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 2.87 kg (force ~28.14 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it 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 15 mm. 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.

Pros and cons of rare earth magnets.

Pros

Besides their immense pulling force, neodymium magnets offer the following advantages:

They have stable power, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
They maintain their magnetic properties even under close interference source,
The use of an refined coating of noble metals (nickel, gold, silver) causes the element to present itself better,
The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
In view of the ability of accurate shaping and adaptation to specialized requirements, NdFeB magnets can be manufactured in a wide range of forms and dimensions, which amplifies use scope,
Significant place in advanced technology sectors – they find application in HDD drives, electromotive mechanisms, precision medical tools, also industrial machines.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of neodymium magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
We recommend cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complex shapes.
Possible danger related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these products can complicate diagnosis medical when they are in the body.
Due to complex production process, their price exceeds standard values,

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

Information about lifting capacity is the result of a measurement for optimal configuration, including:

on a base made of structural steel, optimally conducting the magnetic field
whose transverse dimension reaches at least 10 mm
with an polished contact surface
under conditions of no distance (metal-to-metal)
for force acting at a right angle (pull-off, not shear)
at ambient temperature room level

Practical aspects of lifting capacity – factors

Bear in mind that the application force will differ influenced by elements below, starting with the most relevant:

Distance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
Angle of force application – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Material composition – not every steel attracts identically. High carbon content worsen the attraction effect.
Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Temperature influence – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was measured by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets

Flammability

Dust generated during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Electronic devices

Do not bring magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.

Pacemakers

For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to work with the magnets.

Threat to navigation

Remember: rare earth magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your mobile, device, and navigation systems.

Do not underestimate power

Handle magnets consciously. Their powerful strength can surprise even professionals. Stay alert and respect their power.

Maximum temperature

Keep cool. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Sensitization to coating

Studies show that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands or choose coated magnets.

Product not for children

These products are not toys. Swallowing several magnets can lead to them attracting across intestines, which constitutes a severe health hazard and requires urgent medical intervention.

Bodily injuries

Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Risk of cracking

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

Warning! More info about hazards in the article: Safety of working with magnets.
