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 decreases drastically with every mm of distance. Remember that even the smallest gap (e.g., contamination, varnish, veneer) strongly reduces the pull force. Magnets hold strongest in perfect adhesion; distance kills the power. Observe how rapidly the parameters drop, when the magnet does not adhere tightly to the steel surface. When calculating the arrangement, avoid unnecessary gaps.

The table below shows the theoretical force sufficient to initiate the downward movement of the magnet downwards against a vertical steel wall (assuming typical friction). This parameter depends on the gap size between the magnet and the metal.

When placing a magnet on a vertical surface (e.g., a car body), it you can count on only approx. 1/5 of nominal attraction strength. Gravity and a low friction coefficient cause that holders slip easier than they pull off. Planning a hanger? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the magnet will give way down under a noticeably lighter weight. Utilizing a rubberized layer can drastically improve the result.

A thin sheet is incapable of focus the entire magnetic field, which squanders power of the holder. Should you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze 100% of this magnet's potential, you need a suitably thick element of steel. The saturation effect causes that on delicate walls (e.g., appliance housings), the product works worse. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products lose strength past the thermal threshold. Protect against heat – heat can permanently destroy this magnet. With increasing heat, the magnet's power temporarily drops. Avoid using this magnet close to heaters higher than its working range. Ignoring the limit will result in destruction of magnetic properties.
*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnets interact from a wider radius than a neodymium and metal setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Designing a solid fastener? Apply two magnets instead of one magnet and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is huge. The levitation is marginally weaker than the connection force, but still significant.
*The magnetic induction in repulsion mode reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Note: Figures demonstrate shear force of two identical magnets (friction ~0.15 for Ni-Ni layer).

NdFeB products are prone to chipping – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or painful pinches to fingers. 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 handling with large magnets.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

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

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly weakens 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) = 0.44

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.

The presented product is a very strong cylindrical magnet, composed of advanced NdFeB material, which, with dimensions of Ø12x4 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 3.45 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 33.81 N with a weight of only 3.39 g, this rod is indispensable in electronics and wherever low weight is crucial.
Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 12.1 mm) using two-component epoxy glues. To ensure long-term durability 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 professional neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø12x4), 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 12 mm and height 4 mm. The key parameter here is the holding force amounting to approximately 3.45 kg (force ~33.81 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.
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 12 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.

Advantages and disadvantages of Nd2Fe14B magnets.

Strengths

Apart from their notable magnetic energy, neodymium magnets have these key benefits:
  • They retain full power for nearly ten years – the drop is just ~1% (based on simulations),
  • They are resistant to demagnetization induced by external field influence,
  • The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to look better,
  • The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Thanks to modularity in designing and the ability to adapt to client solutions,
  • Universal use in electronics industry – they find application in data components, electric drive systems, advanced medical instruments, as well as other advanced devices.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:
  • Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
  • NdFeB 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 when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Due to limitations in producing threads and complex shapes in magnets, we propose using cover - magnetic mechanism.
  • Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these devices can complicate diagnosis 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

Maximum lifting force for a neodymium magnet – what contributes to it?

The force parameter is a theoretical maximum value executed under specific, ideal conditions:
  • with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
  • possessing a thickness of at least 10 mm to ensure full flux closure
  • characterized by smoothness
  • without any insulating layer between the magnet and steel
  • during pulling in a direction perpendicular to the mounting surface
  • at temperature room level

Impact of factors on magnetic holding capacity in practice

It is worth knowing that the working load may be lower influenced by the following factors, starting with the most relevant:
  • Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
  • Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Plate material – mild steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
  • Smoothness – full contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
  • Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.

Safe handling of NdFeB magnets
Fragile material

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets leads to them breaking into small pieces.

Nickel allergy

It is widely known that the nickel plating (the usual finish) is a common allergen. If you have an allergy, avoid direct skin contact and select coated magnets.

Handling guide

Use magnets consciously. Their immense force can shock even professionals. Be vigilant and respect their force.

Warning for heart patients

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Flammability

Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Compass and GPS

Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Pinching danger

Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Operating temperature

Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Do not give to children

Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Store away from kids and pets.

Safe distance

Device Safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
