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.

Grip strength weakens drastically per each millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, rust) strongly weakens the grip. Magnetic products operate strongest in perfect adhesion; distance kills the force. See how rapidly the parameters fall, when the magnet does not touch tightly to the metal substrate. When planning the assembly, eliminate unnecessary gaps.

The following data shows the estimated weight limit sufficient to start the shifting of the magnet vertically on a vertical metal surface (assuming typical friction). This parameter varies with the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 33x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	7.10 kg / 15.66 lbs 7101.0 g / 69.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.73 kg / 10.44 lbs 4734.0 g / 46.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.37 kg / 5.22 lbs 2367.0 g / 23.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	11.84 kg / 26.09 lbs 11835.0 g / 116.1 N

When hanging a holder on a vertical wall (e.g., a board), it will maintain just about 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip mean that magnets slip faster than they detach. Want to create a wall mount? Consider that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the holder will give way down under a significantly smaller weight. Using a rubber layer can significantly raise the stability.

A thin metal plate is incapable of conduct the full magnetic flux, which wastes potential of the holder. If you attach a powerful product to a weak sheet, the field will pass right through and the attraction force will be weaker. To utilize 100% of this magnet's potential, you need a suitably thick piece of steel. The saturation effect causes that on thin elements (e.g., car bodies), the product works worse. We suggest choosing the steel cross-section according to the table below.

Classic neodymiums change their properties strength above the temperature limit. Avoid high temperatures – high temperature can irreversibly damage this magnet. As the temperature rises, the magnet's force momentarily lowers. Refrain from using this magnet in hot environments exceeding its operating temperature limit. Too high temperature will result in destruction of magnetic properties.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two magnets attract each other from a much further distance than a neodymium and metal combination. The setup of magnet-to-magnet produces a massive flux and a further horizon of performance. Want to build a solid fastener? Apply two magnets instead of a neodymium and a steel. Remember that when attracting two neodymiums, the impact force is extreme. The repulsion force is a bit weaker than the attraction, but still large.
*Flux density between like poles is approximately ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Attention: Results demonstrate shear force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a large risk to electronics and medical implants. These NdFeB products generate a flux that destroys function of digital equipment. Notice: the invisible magnetic field acts through matter and plastic. Exceptional care must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, car keys, speakers, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

NdFeB products are prone to chipping – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can trigger coating fragments or injury to skin. Be sure to control the product during mounting so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Use safety goggles when playing with large magnets.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Note: On a vertical wall, the magnet retains merely a fraction of its max power.

2. Plate thickness effect

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.40

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 P_c (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 P_c 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 offered product is an exceptionally strong rod magnet, composed of modern NdFeB material, which, with dimensions of Ø33x10 mm, guarantees maximum efficiency. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 23.67 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building generators, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 232.15 N with a weight of only 64.15 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 33.1 mm) using epoxy glues. To ensure long-term durability 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 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 (Ø33x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 33 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 23.67 kg (force ~232.15 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 10 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 through the diameter if your project requires it.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Besides their high retention, neodymium magnets are valued for these benefits:

They do not lose strength, even during around ten years – the decrease in strength is only ~1% (according to tests),
Magnets very well defend themselves against demagnetization caused by ambient magnetic noise,
The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
Thanks to versatility in designing and the ability to adapt to specific needs,
Key role in advanced technology sectors – they find application in computer drives, drive modules, medical equipment, also other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets experience a drop in strength. 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
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Limited ability of producing threads in the magnet and complicated shapes - recommended is casing - magnetic holder.
Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Highest magnetic holding force – what contributes to it?

Breakaway force was determined for optimal configuration, including:

with the contact of a yoke made of low-carbon steel, ensuring maximum field concentration
whose transverse dimension reaches at least 10 mm
with a plane perfectly flat
under conditions of no distance (metal-to-metal)
during pulling in a direction vertical to the plane
at room temperature

Practical aspects of lifting capacity – factors

Real force is affected by working environment parameters, including (from priority):

Clearance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Chemical composition of the base – mild steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

Safe handling of neodymium magnets

Health Danger

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Allergy Warning

It is widely known that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent direct skin contact and opt for encased magnets.

Crushing risk

Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!

Shattering risk

Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.

Maximum temperature

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

Safe operation

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.

Impact on smartphones

Be aware: rare earth magnets produce a field that interferes with sensitive sensors. Keep a separation from your mobile, device, and navigation systems.

Magnetic media

Avoid bringing magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.

Flammability

Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Product not for children

Always keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are very dangerous.
