Grip strength decreases drastically with every mm of spacing. Note that even the smallest gap (e.g., contamination, varnish, rust) strongly reduces the pull force. Magnetic products hold optimally in perfect adhesion; distance drastically cuts the power. See how quickly the parameters drop, when the product does not touch directly to the steel surface. When calculating the assembly, eliminate additional spacers.

The following data defines the estimated force needed to start the shifting of the magnet vertically against a upright steel wall (assuming standard friction coefficient). This value is relative to the distance between the magnet and the metal.

When mounting a holder on a vertical wall (e.g., a board), it will only hold only approx. 20%-30% of nominal attraction strength. Gravity and a weak degree of grip influence the fact that holders slide down easier than they detach. Designing a vertical fastening? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a noticeably lighter cargo. Using a rubber pad can significantly improve the result.

A thin metal plate is incapable of take in the entire magnetic field, which squanders power of the magnet. If you mount a strong magnet to a weak sheet, the field will penetrate right through and the holding will be smaller. To utilize the maximum of this neodymium's power, you need a suitably thick piece of steel. The material oversaturation causes that on sheet metal structures (e.g., car bodies), the product shows lower pull force. We advise picking the steel cross-section based on the following data.

Ordinary NdFeB products irreversibly lose strength above the temperature limit. Watch out for overheating – high temperature can permanently damage this product. With increasing heat, the magnet's power momentarily drops. Do not use this product close to ovens higher than its operating temperature limit. Ignoring the limit will cause irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) risk losing magnetic properties sooner than long magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two magnets attract each other from a significantly greater distance than a magnet and steel setup. The setup of two magnets produces a massive flux and a larger range of operation. Designing a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is extreme. The repulsion force is a bit weaker than the attraction, but still significant.
*The magnetic induction in repulsion mode is approximately ~0 Gs in the exact middle between the magnets (due to field cancellation).
Attention: Calculations demonstrate sliding force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a large risk to electronics as well as medical implants. These NdFeB products generate a field that prevents correct functioning of digital equipment. Remember: the unseen radiation penetrates the body and housings. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - warning

100 mm	117.22 km/h (32.56 m/s)	0.80 J

NdFeB products are delicate – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose turns into a projectile. Striking energy can cause material chips or dangerous crushing to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when working with large magnets.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds merely approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Power loss vs temp

*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) = 0.59

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 presented product is an exceptionally strong cylinder magnet, manufactured from modern NdFeB material, which, at dimensions of Ø8x4 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 2.04 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 20.00 N with a weight of only 1.51 g, this rod is indispensable in electronics 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., 8.1 mm) using epoxy glues. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are strong enough for 90% of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø8x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø8x4 mm, which, at a weight of 1.51 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 2.04 kg (force ~20.00 N), which, with such defined 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 8 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.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

Besides their tremendous strength, neodymium magnets offer the following advantages:

They do not lose strength, even during around 10 years – the decrease in strength is only ~1% (theoretically),
Magnets very well resist against loss of magnetization caused by external fields,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
They are known for high magnetic induction at the operating surface, which increases their power,
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 forming and the ability to customize to specific needs,
Versatile presence in high-tech industry – they are commonly used in data components, electromotive mechanisms, medical equipment, and technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Weaknesses

Cons of neodymium magnets and ways of using them

Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their 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.
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
Limited possibility of making threads in the magnet and complex shapes - preferred is a housing - magnet mounting.
Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
Due to neodymium price, their price is relatively high,

Holding force characteristics

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

Magnet power is the result of a measurement for optimal configuration, assuming:

using a plate made of low-carbon steel, functioning as a magnetic yoke
with a cross-section of at least 10 mm
with an ideally smooth contact surface
without the slightest air gap between the magnet and steel
during detachment in a direction perpendicular to the plane
in neutral thermal conditions

What influences lifting capacity in practice

In practice, the real power is determined by many variables, ranked from crucial:

Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (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 holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.

Warnings

Finger safety

Large magnets can break fingers instantly. Do not place your hand betwixt two strong magnets.

Permanent damage

Monitor thermal conditions. Exposing the magnet to high heat will destroy its magnetic structure and strength.

Respect the power

Be careful. Rare earth magnets act from a long distance and connect with massive power, often faster than you can react.

Medical interference

Warning for patients: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to handle the magnets.

Impact on smartphones

GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.

Adults only

Only for adults. Tiny parts can be swallowed, leading to serious injuries. Store out of reach of children and animals.

Cards and drives

Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Sensitization to coating

Medical facts indicate that nickel (standard magnet coating) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands and choose versions in plastic housing.

Material brittleness

Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.

Combustion hazard

Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
