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.

1. Shear force

*Caution: On a vertical surface, the magnet holds merely ~20% of its perpendicular strength.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Temperature resistance

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.74

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.

Other products

This product is an extremely powerful cylinder magnet, produced from advanced NdFeB material, which, at dimensions of Ø14x10 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 6.71 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, 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 magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 65.83 N with a weight of only 11.55 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.
Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Magnets NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø14x10), 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 14 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 6.71 kg (force ~65.83 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 14 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.

Pros as well as cons of rare earth magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose strength, even after approximately 10 years – the reduction in strength is only ~1% (based on measurements),
  • Neodymium magnets are distinguished by exceptionally resistant to magnetic field loss caused by external interference,
  • In other words, due to the smooth layer of nickel, the element gains a professional look,
  • Magnets are characterized by maximum magnetic induction on the surface,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Thanks to versatility in forming and the capacity to modify to complex applications,
  • Versatile presence in high-tech industry – they are used in HDD drives, drive modules, medical devices, as well as complex engineering applications.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in miniature devices

Cons

Disadvantages of neodymium magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
  • Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • Due to limitations in producing threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
  • Potential hazard related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child health protection. Furthermore, small components of these products can disrupt the diagnostic process medical when they are in the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

Best holding force of the magnet in ideal parameterswhat contributes to it?

Information about lifting capacity was defined for ideal contact conditions, assuming:
  • using a sheet made of high-permeability steel, acting as a circuit closing element
  • whose transverse dimension equals approx. 10 mm
  • characterized by even structure
  • under conditions of gap-free contact (surface-to-surface)
  • under axial force vector (90-degree angle)
  • at standard ambient temperature

Practical lifting capacity: influencing factors

It is worth knowing that the working load will differ influenced by elements below, in order of importance:
  • Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Angle of force application – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
  • Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
  • Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

H&S for magnets
Conscious usage

Handle magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their force.

Allergic reactions

Some people experience a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to an allergic reaction. We suggest wear protective gloves.

Beware of splinters

Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.

Threat to navigation

A strong magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.

Physical harm

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

Power loss in heat

Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.

Product not for children

Only for adults. Small elements can be swallowed, leading to intestinal necrosis. Keep out of reach of children and animals.

Keep away from computers

Avoid bringing magnets near a wallet, computer, or screen. The magnetism can destroy these devices and erase data from cards.

Mechanical processing

Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Medical interference

Individuals with a ICD must maintain an large gap from magnets. The magnetic field can interfere with the functioning of the life-saving device.
