Grip strength decreases drastically with every mm of gap. Remember that even the smallest gap (e.g., contamination, varnish, dust) noticeably weakens the grip. Magnets work most effectively during direct contact; gap weakens the power. See how flashily the load capacity drop, when the product does not touch tightly to the metal substrate. When planning the arrangement, avoid unnecessary gaps.

The table below presents the estimated shear load sufficient to start the sliding of the magnet down along a vertical steel plate (considering typical friction). The holding force varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 18.9x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.50 kg / 7.72 pounds 3504.0 g / 34.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.34 kg / 5.15 pounds 2336.0 g / 22.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.17 kg / 2.57 pounds 1168.0 g / 11.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.84 kg / 12.87 pounds 5840.0 g / 57.3 N

When placing a magnet on a vertical wall (e.g., a fridge), it will maintain just about 20%-30% of its nominal power. Gravitational force and a low friction coefficient cause that holders move down faster than they pop off the substrate. Designing a wall mount? Consider that the shear force is much weaker than the maximum static pull force. On a slippery surface, the holder will slip down under a significantly smaller load. Utilizing a rubberized coating can drastically increase the grip.

12 mm	100%	11.68 kg / 25.75 pounds 11680.0 g / 114.6 N

A thin sheet is incapable of conduct the entire magnetic field, which wastes potential of the holder. Should you install a neodymium to a weak sheet, the flux will penetrate right through and the holding will be smaller. To utilize 100% of this magnet's power, you need a suitably thick element of steel. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the magnet works worse. We advise picking the steel cross-section based on the following data.

Classic neodymiums irreversibly lose power above the temperature limit. Watch out for overheating – heat can irreversibly demagnetize this product. As the temperature rises, the magnet's force temporarily decreases. Do not use this product close to ovens higher than its operating temperature limit. Too high temperature will cause permanent loss of magnetism.

*Engineering note: Thermal stability is determined by both grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) are more susceptible to demagnetization sooner than long magnets. Red status in the table points to a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a significantly greater distance than a magnet and steel setup. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of action. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is marginally weaker than the connection force, but still large.
*Field value in repulsion mode is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Note: Estimates refer to sliding force of two matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a large risk to electronic devices as well as medical implants. These magnets produce a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field penetrates the body and glass. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, remotes, speakers, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

NdFeB products are delicate – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the magnet. Wear eye protection when handling with powerful specimens.

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains merely ~20% of its max power.

2. Plate thickness effect

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

3. Thermal stability

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.61

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 an extremely powerful rod magnet, manufactured from modern NdFeB material, which, at dimensions of Ø18.9x10 mm, guarantees maximum efficiency. This specific item is characterized by an accuracy of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 11.68 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 114.54 N with a weight of only 21.04 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 18.9.1 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 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 even stronger magnets in the same volume (Ø18.9x10), 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 18.9 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 11.68 kg (force ~114.54 N), which, with such compact dimensions, proves the high power of the NdFeB material. 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 18.9 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 Nd₂Fe₁₄B magnets.

Strengths

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

They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
Magnets very well resist against loss of magnetization caused by foreign field sources,
By using a decorative layer of nickel, the element has an aesthetic look,
Magnetic induction on the top side of the magnet is very high,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to modularity in constructing and the capacity to customize to unusual requirements,
Wide application in electronics industry – they are utilized in magnetic memories, electric motors, diagnostic systems, as well as technologically advanced constructions.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

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 protects the magnet but also improves its resistance to damage
Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
Due to limitations in producing nuts and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these products can be problematic in diagnostics medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum magnetic pulling force – what contributes to it?

The lifting capacity listed is a theoretical maximum value performed under specific, ideal conditions:

using a base made of high-permeability steel, acting as a ideal flux conductor
possessing a thickness of min. 10 mm to ensure full flux closure
with a plane perfectly flat
under conditions of ideal adhesion (surface-to-surface)
during detachment in a direction vertical to the plane
at room temperature

Determinants of lifting force in real conditions

Please note that the working load may be lower influenced by elements below, in order of importance:

Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
Direction of force – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
Surface finish – ideal contact is possible only on polished steel. Rough texture create air cushions, reducing force.
Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate decreases the load capacity.

Safe handling of NdFeB magnets

Hand protection

Big blocks can smash fingers instantly. Never place your hand betwixt two attracting surfaces.

Do not overheat magnets

Avoid heat. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Dust is flammable

Machining of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Life threat

Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Magnetic media

Data protection: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Product not for children

Neodymium magnets are not toys. Swallowing multiple magnets can lead to them attracting across intestines, which poses a critical condition and requires urgent medical intervention.

Beware of splinters

Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.

Skin irritation risks

A percentage of the population experience a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Prolonged contact may cause dermatitis. We strongly advise use protective gloves.

Respect the power

Handle magnets consciously. Their powerful strength can shock even experienced users. Plan your moves and respect their force.

GPS and phone interference
