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 per each millimeter of distance. Keep in mind that even the smallest gap (e.g., dirt, varnish, dust) significantly weakens the grip. Magnetic products work optimally at the point of direct contact; air break nullifies the power. Notice how quickly the pull force plummet, when the magnet does not touch flatly to the steel surface. When calculating the arrangement, eliminate unnecessary gaps.

When mounting a magnet on a upright plane (e.g., a board), it you can count on barely about 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient cause that holders slide down faster than they detach. Want to create a hanger? Remember that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the element will slip down under a noticeably lighter weight. Application of an anti-slip pad can effectively increase the grip.

A thin metal plate cannot absorb the entire magnetic field, which squanders power of the magnet. If you install a neodymium to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To utilize 100% of this neodymium's power, you require a sufficiently solid piece of steel. The material oversaturation means that on sheet metal structures (e.g., appliance housings), the holder holds weaker. We recommend selecting the steel cross-section according to the table below.

Standard neodymium magnets change their properties parameters past the thermal threshold. Protect against heat – excessive heat can irreversibly demagnetize this magnet. As the temperature rises, the magnet's power temporarily lowers. Avoid using this magnet in hot environments exceeding its operating temperature limit. Ignoring the limit will result in irreversible degradation of magnetism.
*Engineering note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) may lose charge permanently under lower heat stress than long magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a neodymium and metal setup. The connection of magnet-to-magnet generates a stronger field and a further horizon of action. Designing a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the impact force is massive. The repulsion force is slightly lower than the attraction, but still significant.
*The magnetic induction between like poles drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Estimates show sliding force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a real danger to IT equipment and medical implants. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and housings. Increased vigilance must be exercised by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a strong collision with metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can trigger coating fragments or painful pinches to skin. Be sure to control the product during installation so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the magnet. Wear safety glasses when handling with powerful specimens.

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. Vertical hold

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

2. Efficiency vs thickness

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

3. Power loss vs temp

*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) = 0.78

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 exceptionally strong cylinder magnet, manufactured from durable NdFeB material, which, at dimensions of Ø45x35 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 68.98 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 676.73 N with a weight of only 417.49 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
Due to the delicate structure of the ceramic sinter, 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 durability 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 (Ø45x35), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 45 mm and height 35 mm. The value of 676.73 N means that the magnet is capable of holding a weight many times exceeding its own mass of 417.49 g. The product has a [NiCuNi] coating, which secures it 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 45 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 as well as weaknesses of neodymium magnets.

Pros

Besides their durability, neodymium magnets are valued for these benefits:
  • They retain attractive force for almost 10 years – the loss is just ~1% (in theory),
  • They feature excellent resistance to magnetic field loss due to opposing magnetic fields,
  • Thanks to the metallic finish, the coating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
  • They feature high magnetic induction at the operating surface, which affects their effectiveness,
  • 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...
  • In view of the ability of free shaping and adaptation to unique needs, magnetic components can be manufactured in a broad palette of forms and dimensions, which amplifies use scope,
  • Significant place in future technologies – they are commonly used in computer drives, electric motors, medical equipment, as well as multitasking production systems.
  • 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 suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • We recommend a housing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
  • Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products are able to be problematic in diagnostics medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

The force parameter is a result of laboratory testing performed under specific, ideal conditions:
  • with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
  • possessing a massiveness of minimum 10 mm to avoid saturation
  • with a plane perfectly flat
  • without the slightest clearance between the magnet and steel
  • during pulling in a direction perpendicular to the mounting surface
  • in stable room temperature

Practical aspects of lifting capacity – factors

It is worth knowing that the magnet holding will differ subject to elements below, starting with the most relevant:
  • Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
  • Material composition – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
  • Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
  • Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.

Safe handling of neodymium magnets
Safe distance

Equipment safety: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Fragile material

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Keep away from electronics

GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.

Mechanical processing

Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Handling rules

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

Allergic reactions

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness appears, immediately stop handling magnets and use protective gear.

Choking Hazard

NdFeB magnets are not toys. Eating several magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and requires urgent medical intervention.

Bone fractures

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

Permanent damage

Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.

Implant safety

For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
