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. Wall mount (shear)

*Caution: On a vertical surface, the magnet retains merely approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) significantly reduces the holding force.

3. Power loss vs temp

*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) = 0.89

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 incredibly powerful cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø6x6 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.14 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is perfect for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 11.18 N with a weight of only 1.27 g, this rod is indispensable in electronics and wherever every gram matters.
Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating 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.
Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø6x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
This model is characterized by dimensions Ø6x6 mm, which, at a weight of 1.27 g, makes it an element with high magnetic energy density. The value of 11.18 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.27 g. 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 6 mm. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. 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 high retention, neodymium magnets are valued for these benefits:
  • Their strength remains stable, and after around ten years it drops only by ~1% (theoretically),
  • They have excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
  • Thanks to the reflective finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
  • Magnetic induction on the working layer of the magnet remains strong,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to modularity in forming and the ability to customize to complex applications,
  • Significant place in innovative solutions – they serve a role in magnetic memories, motor assemblies, medical equipment, also technologically advanced constructions.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Disadvantages of NdFeB magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
  • When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding 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.
  • Due to limitations in creating nuts and complex forms in magnets, we recommend using a housing - magnetic mount.
  • Health risk to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these devices are able to 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 can limit application in large quantities

Lifting parameters

Magnetic strength at its maximum – what it depends on?

The lifting capacity listed is a measurement result conducted under the following configuration:
  • on a block made of mild steel, effectively closing the magnetic field
  • with a thickness no less than 10 mm
  • with an ground touching surface
  • with zero gap (without impurities)
  • during detachment in a direction vertical to the plane
  • at ambient temperature room level

Determinants of practical lifting force of a magnet

Effective lifting capacity is influenced by specific conditions, including (from priority):
  • Air gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
  • Angle of force application – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
  • Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
  • Steel grade – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
  • Surface condition – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
  • Temperature – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet and the plate lowers the holding force.

Safety rules for work with neodymium magnets
Fire warning

Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Crushing force

Large magnets can break fingers in a fraction of a second. Do not put your hand between two strong magnets.

Warning for allergy sufferers

Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease handling magnets and use protective gear.

Heat sensitivity

Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. Damage is permanent.

ICD Warning

Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

This is not a toy

Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Store away from children and animals.

Keep away from computers

Device Safety: Strong magnets can damage data carriers and delicate electronics (heart implants, hearing aids, timepieces).

Eye protection

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.

Handling rules

Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often faster than you can react.

Compass and GPS

An intense magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.
