Magnetic force weakens sharply with every mm of distance. Keep in mind that even a microscopic distance (e.g., contamination, varnish, rust) noticeably reduces the pull force. Magnets operate strongest at the point of direct contact; air break drastically cuts the power. Notice how quickly the pull force plummet, when the product does not touch flatly to the metal substrate. When designing the mounting, avoid redundant distances.

The following data shows the theoretical shear load needed to initiate the slippage of the magnet down along a vertical metal surface (considering typical friction coefficient). The holding force varies with the gap size between the magnet and the surface.

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.29 kg / 0.65 LBS 294.0 g / 2.9 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.74 kg / 1.62 LBS 735.0 g / 7.2 N

When placing a element on a upright plane (e.g., a car body), it you can count on barely approx. 1/5 of its maximum pull force. Gravity as well as a weak degree of grip influence the fact that magnets move down faster than they detach. Planning a wall mount? Consider that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the magnet will give way down under a significantly smaller cargo. Using a rubber coating can effectively improve the result.

A too thin steel is not enough to take in the entire magnetic field, which wastes potential of the magnet. If you install a neodymium to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To utilize the maximum of this magnet's power, you require a sufficiently solid piece of metal. The saturation phenomenon means that on sheet metal structures (e.g., thin profiles), the magnet shows lower pull force. We advise picking the steel dimension from these parameters.

Standard neodymium magnets irreversibly lose strength above the temperature limit. Watch out for overheating – heat can permanently damage this magnet. As the temperature rises, the magnet's force momentarily drops. Do not use this magnet close to ovens higher than its safe range. Ignoring the limit will lead to permanent loss of magnetism.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) may lose charge permanently under lower heat stress than long magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a wider radius than a magnet and sheet combination. Such a system of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Designing a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Remember that when bringing together two magnets, the pinch force is extreme. The repulsion force is slightly lower than the connection force, but still impressive.
*Field value in repulsion mode reaches ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
* Estimates refer to friction force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a serious hazard to electronics and medical implants. These neodymiums produce a field that destroys function of digital equipment. Remember: the invisible magnetic field passes through tissues and glass. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely speeds with massive force. Impact energy can cause material chips or injury to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when working with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*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) severely limits the holding force.

3. Temperature resistance

*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) = 1.19

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.

This product is an extremely powerful rod magnet, composed of advanced NdFeB material, which, with dimensions of Ø8x15 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.47 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 14.45 N with a weight of only 5.65 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure long-term durability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are suitable for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø8x15), 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 8 mm and height 15 mm. The value of 14.45 N means that the magnet is capable of holding a weight many times exceeding its own mass of 5.65 g. 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 8 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 through the diameter if your project requires it.

Advantages as well as disadvantages of rare earth magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They do not lose magnetism, even over around ten years – the drop in power is only ~1% (theoretically),
They possess excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
By covering with a lustrous layer of nickel, the element gains an elegant look,
The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Thanks to flexibility in forming and the ability to customize to complex applications,
Fundamental importance in advanced technology sectors – they are used in hard drives, electric drive systems, diagnostic systems, also other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 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 secure oxidation as well as corrosion.
Limited ability of making nuts in the magnet and complex forms - recommended is a housing - magnetic holder.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can complicate diagnosis medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Holding force characteristics

Highest magnetic holding force – what contributes to it?

The force parameter is a measurement result conducted under specific, ideal conditions:

on a base made of structural steel, optimally conducting the magnetic field
with a thickness minimum 10 mm
with an polished touching surface
under conditions of no distance (surface-to-surface)
during detachment in a direction perpendicular to the mounting surface
in neutral thermal conditions

Practical aspects of lifting capacity – factors

Please note that the application force will differ influenced by elements below, starting with the most relevant:

Air gap (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic permeability and lifting capacity.
Plate texture – ground elements ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate lowers the load capacity.

Warnings

Nickel coating and allergies

Some people have a contact allergy to nickel, which is the common plating for neodymium magnets. Extended handling might lead to an allergic reaction. We suggest wear protective gloves.

Precision electronics

GPS units and smartphones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Magnetic media

Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Do not overheat magnets

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

Shattering risk

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Powerful field

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Do not drill into magnets

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

Crushing force

Risk of injury: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.

Do not give to children

Absolutely keep magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are fatal.

Danger to pacemakers

Warning for patients: Powerful magnets affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
