Pulling power decreases drastically with every subsequent millimeter of spacing. Remember that every additional insulation layer (e.g., contamination, varnish, dust) significantly reduces the pull force. Magnetic products operate strongest at the point of direct contact; gap drastically cuts the power. See how flashily the parameters plummet, when the magnet does not touch tightly to the metal substrate. When planning the arrangement, eliminate additional spacers.

The following data defines the approximate weight limit necessary to initiate the slippage of the magnet vertically on a upright steel wall (considering standard friction coefficient). This parameter is a function of the air gap between the magnet and the surface.

When hanging a holder on a vertical plane (e.g., a car body), it you can count on barely approx. 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that holders slip faster than they pop off the substrate. Designing a vertical fastening? Note that the shear force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will give way down under a much lighter weight. Application of an anti-slip pad can drastically increase the grip.

A thin metal plate is unable to focus the full magnetic flux, which weakens actual performance of the holder. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To utilize the maximum of this magnet's potential, you require a sufficiently solid element of steel. The saturation effect causes that on thin elements (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel cross-section based on the following data.

Classic neodymiums change their properties strength past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly damage this magnet. With increasing heat, the magnet's power temporarily lowers. Avoid using this product close to heaters exceeding its operating temperature limit. Ignoring the limit will result in irreversible degradation of magnetic properties.
*Important note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) may lose charge permanently at lower temperatures than long magnets. Warning indicator in the table signals permanent field degradation for this particular item.

Two magnets attract each other from a much further distance than a magnet and sheet setup. The setup of magnet-to-magnet generates a stronger field and a wider radius of operation. Designing a strong closure? Apply two magnets instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the impact force is massive. The levitation is slightly lower than the attraction, but still large.
*Flux density in repulsion mode is approximately ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Figures demonstrate sliding force of two same magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a real danger to electronics as well as pacemakers. These magnets generate a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and housings. Special caution must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Kinetic force can trigger coating fragments or painful pinches 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 almost guarantees destruction of the magnet. Wear safety glasses when playing with powerful specimens.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

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

2. Plate thickness effect

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.63

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 Pc (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 Pc 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 cylinder magnet, composed of advanced NdFeB material, which, with dimensions of Ø16x9 mm, guarantees the highest energy density. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 8.53 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is perfect for building generators, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 83.64 N with a weight of only 13.57 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., 16.1 mm) using two-component epoxy glues. To ensure stability in industry, specialized industrial adhesives 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 the majority 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 (Ø16x9), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
This model is characterized by dimensions Ø16x9 mm, which, at a weight of 13.57 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 8.53 kg (force ~83.64 N), which, with such compact 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 through the diameter if your project requires it.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Strengths

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They do not lose power, even during around 10 years – the reduction in lifting capacity is only ~1% (based on measurements),
  • They retain their magnetic properties even under external field action,
  • A magnet with a shiny gold surface looks better,
  • The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to freedom in shaping and the capacity to modify to individual projects,
  • Fundamental importance in advanced technology sectors – they serve a role in magnetic memories, drive modules, medical devices, also industrial machines.
  • Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of NdFeB magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
  • Limited possibility of making nuts in the magnet and complex shapes - preferred is cover - magnetic holder.
  • Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical after entering the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

Highest magnetic holding force – what contributes to it?

The load parameter shown concerns the maximum value, measured under optimal environment, namely:
  • with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
  • possessing a massiveness of minimum 10 mm to avoid saturation
  • with an polished contact surface
  • without the slightest air gap between the magnet and steel
  • under perpendicular force vector (90-degree angle)
  • in temp. approx. 20°C

Lifting capacity in practice – influencing factors

During everyday use, the actual lifting capacity is determined by many variables, presented from most significant:
  • Clearance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
  • Angle of force application – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
  • Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
  • Steel type – low-carbon steel attracts best. Alloy steels decrease magnetic properties and lifting capacity.
  • Surface structure – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
  • Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the lifting capacity.

Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Dust explosion hazard

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

No play value

Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of children and animals.

Medical implants

Patients with a pacemaker should maintain an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.

Nickel allergy

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease working with magnets and wear gloves.

GPS Danger

Remember: neodymium magnets produce a field that interferes with precision electronics. Keep a separation from your mobile, device, and GPS.

Do not underestimate power

Handle magnets consciously. Their immense force can shock even professionals. Stay alert and respect their power.

Beware of splinters

Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.

Electronic devices

Device Safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Do not overheat magnets

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
