Frequently asked questions

What is the maximum working temperature of a disc magnet?
Standard N-series grades work up to 80 °C. Grades N50, N52 and N54 have a lower limit of 60 °C, because coercivity falls as BHmax rises. Higher temperatures require the H (120 °C), SH (150 °C), UH (180 °C), EH (200 °C) or AH (230 °C) series. Within the working range the magnet loses about 0.11% of its induction per degree, and that loss is reversible.
What is the difference between N38, N42 and N52?
The number after N is the energy product BHmax. Moving from N38 to N52 raises it by several tens of percent, but the real holding force increases by roughly 20%, because force also depends on geometry and on the magnetic circuit. N52 costs about twice as much as N42, so for most mounting work N38–N42 is the best price-to-force ratio.
What is the dimensional tolerance?
±0.1 mm as standard, ±0.05 mm to order. The tolerance is stated next to the dimensions on every product page.

Magnetic force drops sharply with every mm of distance. Remember that every additional insulation layer (e.g., contamination, varnish, dust) noticeably diminishes the holding power. Neodymiums operate strongest in perfect adhesion; gap nullifies the power. See how flashily the pull force drop, when the product does not adhere flatly to the steel surface. When planning the arrangement, avoid redundant distances.

The following data shows the theoretical shear load necessary to start the downward movement of the magnet downwards against a vertical steel plate (considering typical friction). This value is a function of the separation distance between the magnet and the metal.

When placing a element on a vertical plane (e.g., a fridge), it you can count on barely approx. 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient mean that products slip easier than they detach. Planning a hanger? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will slide down under a noticeably lighter cargo. Utilizing a rubberized layer can effectively raise the stability.

A too thin steel cannot conduct the entire magnetic field, which squanders power of the holder. Should you mount a strong magnet to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To squeeze the maximum of this magnet's potential, you require a sufficiently solid element of metal. The saturation effect causes that on delicate walls (e.g., thin profiles), the holder shows lower pull force. We recommend selecting the steel thickness according to the table below.

Ordinary NdFeB products change their properties power after exceeding the maximum temperature. Protect against heat – excessive heat can irreversibly demagnetize this product. With every degree above norm, the magnet's force temporarily lowers. Refrain from using this product in hot environments higher than its safe range. Ignoring the limit will lead to permanent loss of magnetic properties.
*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low Pc) may lose charge permanently sooner than taller cylinders. Red status in the table indicates permanent field degradation for this specific geometry.

Two magnets 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 wider radius of operation. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the collision energy is huge. The repulsion force is marginally weaker than the attraction, but still significant.
*Field value between like poles reaches ~0 Gs in the exact middle between the magnets (due to field cancellation).
Attention: Estimates show shear force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a large risk to electronics as well as medical implants. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and glass. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when playing with large magnets.

1. Vertical hold

*Caution: On a vertical surface, the magnet holds only a fraction of its perpendicular strength.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) drastically 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) = 0.35

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 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 cylindrical magnet, composed of durable NdFeB material, which, at dimensions of Ø16x4 mm, guarantees maximum efficiency. This specific item boasts an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 4.43 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 43.46 N with a weight of only 6.03 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.
Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure long-term durability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Magnets N38 are suitable for 90% of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø16x4), 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 16 mm and height 4 mm. The key parameter here is the holding force amounting to approximately 4.43 kg (force ~43.46 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 external factors, 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.

Advantages as well as disadvantages of neodymium magnets.

Pros

Apart from their superior magnetic energy, neodymium magnets have these key benefits:
  • They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
  • Magnets perfectly resist against loss of magnetization caused by foreign field sources,
  • In other words, due to the smooth surface of nickel, the element looks attractive,
  • Magnetic induction on the working layer of the magnet turns out to be strong,
  • 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 constructing and the ability to adapt to client solutions,
  • Universal use in modern technologies – they serve a role in data components, drive modules, medical equipment, as well as other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices

Limitations

Characteristics of disadvantages of neodymium magnets and proposals for their use:
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
  • Neodymium magnets decrease their power 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 stability even at temperatures up to 230°C
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
  • Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
  • With mass production the cost of neodymium magnets can be a barrier,

Lifting parameters

Maximum holding power of the magnet – what it depends on?

The specified lifting capacity represents the peak performance, recorded under ideal test conditions, meaning:
  • on a block made of structural steel, optimally conducting the magnetic field
  • whose thickness is min. 10 mm
  • characterized by even structure
  • without any air gap between the magnet and steel
  • during pulling in a direction vertical to the plane
  • in stable room temperature

Practical aspects of lifting capacity – factors

Effective lifting capacity is affected by working environment parameters, such as (from priority):
  • Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Load vector – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
  • Base massiveness – too thin plate does not accept the full field, causing part of the flux to be wasted into the air.
  • Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
  • Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
  • Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate reduces the lifting capacity.

Safety rules for work with neodymium magnets
Finger safety

Danger of trauma: The pulling power is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.

Fragile material

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Machining danger

Powder produced during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Allergic reactions

A percentage of the population have a sensitization to Ni, which is the standard coating for neodymium magnets. Prolonged contact might lead to skin redness. We strongly advise use safety gloves.

Do not give to children

Neodymium magnets are not toys. Eating a few magnets can lead to them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.

Caution required

Handle with care. Neodymium magnets attract from a distance and snap with massive power, often faster than you can react.

Operating temperature

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

Medical interference

Patients with a heart stimulator must maintain an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.

Compass and GPS

GPS units and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Data carriers

Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
