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.

Pulling power drops drastically with every subsequent millimeter of gap. Remember that even the smallest gap (e.g., contamination, varnish, dust) noticeably weakens the grip. Neodymiums hold most effectively during direct contact; air break kills the power. See how quickly the parameters plummet, when the product does not adhere flatly to the steel surface. When designing the arrangement, eliminate additional spacers.

The table below indicates the estimated force needed to start the shifting of the magnet downwards against a vertical steel wall (assuming typical friction coefficient). This value is a function of the gap size between the magnet and the metal.

When mounting a element on a vertical plane (e.g., a fridge), it you can count on only approx. 1/5 of its maximum pull force. Gravitational force and a low friction coefficient influence the fact that magnets slip easier than they detach. Designing a hanger? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a much lighter weight. Application of an anti-slip pad can significantly raise the stability.

A thin metal plate is not enough to absorb the entire magnetic field, which squanders power of the holder. Should you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's potential, you require a sufficiently solid backing of metal. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the holder holds weaker. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products lose parameters past the thermal threshold. Watch out for overheating – excessive heat can irreversibly destroy this product. With every degree above norm, the magnet's capacity temporarily decreases. Refrain from using this product in hot environments higher than its operating temperature limit. Too high temperature will result in irreversible degradation of magnetic properties.
*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures compared to rod magnets. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnets attract each other from a significantly greater distance than a neodymium and metal setup. The setup of two magnets creates a more powerful interaction and a further horizon of performance. Want to build a solid fastener? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the collision energy is huge. The repulsion force is a bit weaker than the attraction, but still impressive.
*Field value for N-N configuration drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Important: Results demonstrate shear force of two identical magnets (friction ~0.15 for Ni-Ni plating).

Neodymium magnets are very brittle – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or painful pinches to skin. Be sure to control the product during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when handling 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

*Warning: On a vertical surface, the magnet retains just ~20% of its nominal pull.

2. Steel thickness impact

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

3. Thermal stability

*For N38 grade, the safety limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.63

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 presented product is a very strong cylinder magnet, composed of modern NdFeB material, which, at dimensions of Ø45x25 mm, guarantees optimal power. The MW 45x25 / N38 component is characterized by a tolerance of ±0.1mm and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 67.33 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is ideal for building generators, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 660.51 N with a weight of only 298.21 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.
Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 45.1 mm) using epoxy glues. To ensure stability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø45x25), 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 45 mm and height 25 mm. The value of 660.51 N means that the magnet is capable of holding a weight many times exceeding its own mass of 298.21 g. 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 25 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable 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.

Strengths as well as weaknesses of neodymium magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:
  • Their magnetic field remains stable, and after around 10 years it decreases only by ~1% (theoretically),
  • Neodymium magnets prove to be exceptionally resistant to magnetic field loss caused by external magnetic fields,
  • By applying a lustrous layer of gold, the element has an professional look,
  • Magnetic induction on the surface of the magnet turns out to be exceptional,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to versatility in shaping and the ability to adapt to client solutions,
  • Universal use in high-tech industry – they are used in computer drives, motor assemblies, medical equipment, as well as modern systems.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of neodymium magnets:
  • To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
  • We recommend casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
  • Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small components of these devices can complicate diagnosis 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

Information about lifting capacity is the result of a measurement for ideal contact conditions, including:
  • on a block made of mild steel, optimally conducting the magnetic flux
  • possessing a thickness of min. 10 mm to avoid saturation
  • with an polished touching surface
  • with zero gap (without paint)
  • for force applied at a right angle (in the magnet axis)
  • in stable room temperature

Determinants of practical lifting force of a magnet

Real force impacted by working environment parameters, mainly (from priority):
  • Space between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal 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.
  • Material composition – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
  • Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
  • Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate reduces the load capacity.

H&S for magnets
Choking Hazard

Absolutely keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are tragic.

Hand protection

Big blocks can crush fingers in a fraction of a second. Do not place your hand between two strong magnets.

Danger to pacemakers

Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Do not overheat magnets

Do not overheat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Warning for allergy sufferers

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease working with magnets and wear gloves.

Data carriers

Very strong magnetic fields can destroy records on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.

Powerful field

Handle magnets consciously. Their powerful strength can shock even experienced users. Stay alert and respect their power.

Risk of cracking

Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.

Flammability

Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.

Magnetic interference

A powerful magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to avoid damaging the sensors.
