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. Remember that even the smallest gap (e.g., contamination, paint, veneer) strongly diminishes the holding power. Neodymiums operate optimally during direct contact; air break nullifies the force. Analyze how flashily the load capacity plummet, when the product does not adhere flatly to the metal substrate. When calculating the arrangement, discard redundant distances.

When hanging a magnet on a vertical surface (e.g., a fridge), it you can count on just approx. 1/5 of its maximum pull force. Gravity as well as a weak degree of grip influence the fact that magnets move down easier than they pull off. Planning a wall mount? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the element will give way down under a noticeably lighter cargo. Utilizing a rubberized pad can drastically improve the result.

A thin metal plate is incapable of take in the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To utilize 100% of this neodymium's potential, you require a sufficiently solid piece of metal. The material oversaturation causes that on sheet metal structures (e.g., appliance housings), the magnet works worse. We advise picking the steel thickness from these parameters.

Ordinary NdFeB products irreversibly lose parameters past the thermal threshold. Protect against heat – high temperature can irreversibly damage this product. As the temperature rises, the magnet's power momentarily lowers. Do not use this product close to heaters exceeding its operating temperature limit. Too high temperature will result in destruction of magnetic properties.
*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) risk losing magnetic properties under lower heat stress than long magnets. Red status in the table signals permanent field degradation for this specific geometry.

Two magnets interact from a much further distance than a magnet and sheet combination. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Planning to create a strong closure? Apply two magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the pinch force is extreme. The levitation is marginally weaker than the connection force, but still large.
*The magnetic induction in repulsion mode drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Attention: Calculations apply to shear force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a serious hazard to electronic devices as well as medical implants. These neodymiums generate a flux that prevents correct functioning of digital equipment. Notice: the invisible magnetic field penetrates the body and plastic. Exceptional care must be taken by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Neodymium magnets are delicate – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can cause material chips or dangerous crushing to fingers. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Use safety goggles when playing with large magnets.

1. Shear force

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

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) severely limits the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.38

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.

The offered product is an exceptionally strong cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø10x30 mm, guarantees the highest energy density. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 1.92 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
It successfully proves itself in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 18.79 N with a weight of only 17.67 g, this rod is indispensable in electronics and wherever every gram matters.
Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø10x30), 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 Ø10x30 mm, which, at a weight of 17.67 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 1.92 kg (force ~18.79 N), which, with such compact 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 30 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.

Pros as well as cons of Nd2Fe14B magnets.

Benefits

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
  • They have excellent resistance to weakening of magnetic properties as a result of external fields,
  • Thanks to the smooth finish, the plating of nickel, gold-plated, or silver gives an aesthetic appearance,
  • Magnets are characterized by extremely high magnetic induction on the surface,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to the potential of flexible shaping and adaptation to unique needs, magnetic components can be manufactured in a variety of shapes and sizes, which increases their versatility,
  • Key role in high-tech industry – they are commonly used in data components, brushless drives, precision medical tools, as well as technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in compact constructions

Limitations

What to avoid - cons of neodymium magnets: weaknesses and usage proposals
  • They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
  • Neodymium magnets decrease their strength 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 durability even at temperatures up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
  • We suggest cover - magnetic holder, due to difficulties in creating threads inside the magnet and complicated shapes.
  • Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Maximum holding power of the magnet – what affects it?

Holding force of 1.92 kg is a measurement result executed under the following configuration:
  • using a plate made of high-permeability steel, serving as a ideal flux conductor
  • whose transverse dimension reaches at least 10 mm
  • with a plane perfectly flat
  • under conditions of gap-free contact (metal-to-metal)
  • during detachment in a direction vertical to the plane
  • at temperature room level

Lifting capacity in practice – influencing factors

Real force is affected by working environment parameters, such as (from priority):
  • Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
  • Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
  • Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Material composition – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
  • Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
  • Thermal environment – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

H&S for magnets
Threat to electronics

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

Immense force

Use magnets consciously. Their powerful strength can shock even professionals. Stay alert and do not underestimate their power.

Dust explosion hazard

Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.

Thermal limits

Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Warning for allergy sufferers

Some people have a contact allergy to nickel, which is the common plating for neodymium magnets. Extended handling may cause dermatitis. We recommend use safety gloves.

Choking Hazard

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

Serious injuries

Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Phone sensors

A powerful magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a device to avoid breaking the sensors.

Life threat

Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Material brittleness

Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
