Grip strength drops sharply with every mm of gap. Note that even a microscopic distance (e.g., contamination, varnish, rust) noticeably diminishes the holding power. Neodymiums operate optimally at the point of direct contact; distance kills the power. Notice how rapidly the load capacity fall, when the magnet does not adhere flatly to the steel surface. When designing the arrangement, eliminate additional spacers.

The following data indicates the theoretical shear load necessary to cause the downward movement of the magnet vertically along a upright steel wall (considering typical friction coefficient). This value is relative to the separation distance between the magnet and the metal.

When placing a magnet on a vertical plane (e.g., a fridge), it will only hold just approx. 1/5 of its maximum pull force. Gravity as well as a weak degree of grip influence the fact that holders move down easier than they pop off the substrate. Planning a hanger? Remember that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will give way down under a much lighter weight. Utilizing a rubberized pad can effectively increase the grip.

A thin sheet cannot take in the full magnetic flux, which squanders power of the magnet. Should you mount a strong magnet to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To achieve full efficiency of this magnet's power, you need a suitably thick backing of metal. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the product works worse. We suggest choosing the steel cross-section from these parameters.

Standard neodymium magnets lose power past the thermal threshold. Protect against heat – high temperature can permanently destroy this product. With increasing heat, the magnet's power briefly lowers. Do not use this magnet in hot environments exceeding its safe 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. Low-profile magnets (low permeance coefficient) may lose charge permanently at lower temperatures than taller cylinders. Red status in the table points to a risk of irreversible loss for this particular item.

Two magnetic products interact from a significantly greater distance than a magnet and steel setup. The setup of two magnets produces a massive flux and a further horizon of action. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when bringing together two magnets, the pinch force is massive. The levitation is marginally weaker than the attraction, but still large.
*Field value for N-N configuration reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
* Figures show friction force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronic devices as well as medical implants. These magnets generate a field that destroys function of sensitive medical devices. Remember: the unseen radiation acts through matter and plastic. Special caution must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a strong collision with metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Wear safety glasses when working with large magnets.

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

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Warning: On a vertical surface, the magnet retains only a fraction of its nominal pull.

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) drastically limits the holding force.

3. Thermal stability

*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) = 0.35

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 exceptionally strong cylinder magnet, manufactured from durable NdFeB material, which, with dimensions of Ø16x4 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 4.43 kg), this product is in stock from our European logistics center, 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 43.46 N with a weight of only 6.03 g, this rod is indispensable in miniature devices and wherever every gram matters.

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., 16.1 mm) using epoxy glues. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø16x4), 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 16 mm and height 4 mm. The key parameter here is the lifting capacity amounting to approximately 4.43 kg (force ~43.46 N), which, with such defined dimensions, proves the high grade 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 16 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 diametrically if your project requires it.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

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

They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
They possess excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
In other words, due to the metallic finish of silver, the element is aesthetically pleasing,
Neodymium magnets achieve maximum magnetic induction on a small surface, which increases force concentration,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to modularity in forming and the capacity to adapt to unusual requirements,
Key role in high-tech industry – they are used in hard drives, electromotive mechanisms, diagnostic systems, also technologically advanced constructions.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Limitations

Problematic aspects of neodymium magnets and proposals for their use:

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
Limited possibility of making nuts in the magnet and complicated forms - preferred is cover - magnet mounting.
Health risk to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
With budget limitations the cost of neodymium magnets is a challenge,

Lifting parameters

Detachment force of the magnet in optimal conditions – what it depends on?

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

using a sheet made of low-carbon steel, acting as a magnetic yoke
possessing a thickness of at least 10 mm to avoid saturation
characterized by lack of roughness
without any air gap between the magnet and steel
under perpendicular force vector (90-degree angle)
in temp. approx. 20°C

Key elements affecting lifting force

Bear in mind that the application force may be lower depending on the following factors, in order of importance:

Air gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Load vector – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Chemical composition of the base – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and lifting capacity.
Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
Temperature – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.

Safe handling of neodymium magnets

Bodily injuries

Pinching hazard: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.

This is not a toy

Strictly keep magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are tragic.

Permanent damage

Avoid heat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Sensitization to coating

Some people suffer from a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact may cause a rash. It is best to use protective gloves.

Danger to pacemakers

For implant holders: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.

Do not underestimate power

Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Magnet fragility

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.

Flammability

Powder produced during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Data carriers

Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Impact on smartphones

Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
