Magnetic force weakens drastically with every mm of spacing. Keep in mind that every additional insulation layer (e.g., contamination, varnish, rust) significantly reduces the pull force. Magnetic products operate strongest at the point of direct contact; distance weakens the power. See how flashily the parameters fall, when the magnet does not adhere flatly to the steel surface. When calculating the assembly, discard additional spacers.

The following data defines the estimated force sufficient to initiate the slippage of the magnet vertically along a upright steel plate (considering typical friction). This value is a function of the separation distance between the magnet and the metal.

When hanging a holder on a vertical plane (e.g., a board), it you can count on just approx. 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip mean that holders slip easier than they detach. Designing a vertical fastening? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a significantly smaller load. Using a rubber coating can effectively increase the grip.

A thin metal plate is not enough to focus the full magnetic flux, which weakens actual performance of the holder. If you install a neodymium to a thin surface, the field will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this neodymium's potential, you need a suitably thick element of metal. The saturation effect means that on delicate walls (e.g., appliance housings), the holder holds weaker. We recommend selecting the steel dimension from these parameters.

Ordinary NdFeB products irreversibly lose strength past the thermal threshold. Protect against heat – high temperature can permanently destroy this magnet. As the temperature rises, the neodymium's capacity momentarily drops. Avoid using this product close to heaters higher than its safe range. Too high temperature will cause permanent loss of magnetism.
*Important note: Heat tolerance is determined by both grade, but also on the magnet's shape. Thin magnets (low Pc) risk losing magnetic properties sooner than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two magnetic products interact from a much further distance than a magnet and sheet setup. Such a system of two magnets produces a massive flux and a further horizon of performance. Planning to create a strong closure? Apply two magnets instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the pinch force is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*The magnetic induction between like poles is approximately ~0 Gs in the exact middle of the gap (resulting from vector opposition).
Important: Figures show sliding force of two same magnets (friction coefficient ~0.15 for Ni-Ni layer).

Neodymium magnets are very brittle – a strong collision with metal risks their cracking. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can trigger coating fragments or injury to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the neodymium. Use safety goggles when working with large magnets.

1. Shear force

*Caution: On a vertical wall, the magnet holds just ~20% of its nominal pull.

2. Steel saturation

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

3. Thermal stability

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.44

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 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.

The presented product is an incredibly powerful cylinder magnet, made from durable NdFeB material, which, with dimensions of Ø9x3 mm, guarantees the highest energy density. This specific item features a tolerance of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 1.94 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 18.99 N with a weight of only 1.43 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability in industry, anaerobic resins 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 the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø9x3), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 9 mm and height 3 mm. The key parameter here is the lifting capacity amounting to approximately 1.94 kg (force ~18.99 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 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 diametrically if your project requires it.

Strengths and weaknesses of rare earth magnets.

Strengths

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:
  • They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
  • They retain their magnetic properties even under strong external field,
  • A magnet with a shiny nickel surface is more attractive,
  • They are known for high magnetic induction at the operating surface, which affects their effectiveness,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
  • Thanks to flexibility in designing and the capacity to modify to unusual requirements,
  • Universal use in future technologies – they find application in computer drives, electric motors, diagnostic systems, and multitasking production systems.
  • Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Cons

Problematic aspects of neodymium magnets: application proposals
  • To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • 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. 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 ability of making nuts in the magnet and complicated forms - preferred is casing - magnetic holder.
  • Possible danger to health – tiny shards of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets can disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Magnetic strength at its maximum – what affects it?

The lifting capacity listed is a theoretical maximum value executed under specific, ideal conditions:
  • on a plate made of mild steel, perfectly concentrating the magnetic flux
  • with a cross-section no less than 10 mm
  • with a plane free of scratches
  • with total lack of distance (without coatings)
  • during detachment in a direction perpendicular to the plane
  • at conditions approx. 20°C

Determinants of lifting force in real conditions

It is worth knowing that the working load may be lower depending on elements below, starting with the most relevant:
  • Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
  • Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times smaller (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.
  • Steel grade – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
  • Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
  • Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the holding force.

Warnings
Crushing force

Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.

GPS Danger

A strong magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Do not bring magnets near a device to prevent damaging the sensors.

Life threat

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

This is not a toy

These products are not intended for children. Swallowing several magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.

Electronic devices

Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.

Dust explosion hazard

Dust created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Thermal limits

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

Conscious usage

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

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and use protective gear.
