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 decreases sharply per each millimeter of spacing. Note that even a very thin break (e.g., dirt, paint, rust) significantly diminishes the holding power. Magnetic products operate optimally during direct contact; gap kills the power. Analyze how rapidly the parameters fall, when the magnet does not adhere directly to the steel surface. When planning the mounting, discard redundant distances.

When mounting a magnet on a vertical wall (e.g., a board), it you can count on just approx. 20%-30% of its maximum pull force. Gravity as well as a low friction coefficient mean that magnets move down easier than they pull off. Designing a vertical fastening? Remember that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the holder will slide down under a much lighter load. Using a rubber layer can effectively improve the result.

A thin sheet cannot take in the entire magnetic field, which weakens actual performance of the holder. Should you attach a powerful product to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To utilize full efficiency of this magnet's power, you require a sufficiently solid backing of steel. The material oversaturation causes that on thin elements (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel thickness based on the following data.

Ordinary NdFeB products irreversibly lose parameters above the temperature limit. Watch out for overheating – excessive heat can permanently demagnetize this magnet. As the temperature rises, the magnet's force briefly decreases. Do not use this magnet in hot environments higher than its working range. Ignoring the limit will lead to destruction of magnetism.
*Technical advisory: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low Pc) risk losing magnetic properties at lower temperatures than taller cylinders. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a neodymium and metal combination. Such a system of magnet-to-magnet generates a stronger field and a further horizon of performance. Planning to create 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 extreme. The levitation is marginally weaker than the attraction, but still significant.
*The magnetic induction for N-N configuration drops to ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Attention: Estimates show shear force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field is a real danger to electronic devices as well as pacemakers. These NdFeB products produce a flux that destroys function of sensitive medical devices. Be aware: the unseen radiation passes through tissues and glass. Special caution must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or painful pinches to fingers. Be sure to control the product during bringing near metal so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when working with powerful specimens.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

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

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) drastically weakens the holding force.

3. Power loss vs temp

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.54

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 incredibly powerful cylinder magnet, produced from modern NdFeB material, which, at dimensions of Ø45x20 mm, guarantees the highest energy density. This specific item boasts an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 60.94 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
This model is ideal for building electric motors, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the high power of 597.79 N with a weight of only 238.56 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.
Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 45.1 mm) using epoxy glues. To ensure long-term durability in automation, specialized industrial adhesives 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 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 (Ø45x20), 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 45 mm and height 20 mm. The value of 597.79 N means that the magnet is capable of holding a weight many times exceeding its own mass of 238.56 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 45 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.

Pros as well as cons of Nd2Fe14B magnets.

Advantages

Apart from their superior magnetism, neodymium magnets have these key benefits:
  • They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
  • Magnets perfectly protect themselves against loss of magnetization caused by ambient magnetic noise,
  • The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to present itself better,
  • Magnetic induction on the working layer of the magnet turns out to be maximum,
  • Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
  • Possibility of precise forming and adapting to individual requirements,
  • Fundamental importance in advanced technology sectors – they serve a role in hard drives, electric drive systems, precision medical tools, and industrial machines.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems

Cons

What to avoid - cons of neodymium magnets: application proposals
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
  • Limited possibility of making threads in the magnet and complex shapes - preferred is a housing - magnet mounting.
  • Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
  • With mass production the cost of neodymium magnets is economically unviable,

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what affects it?

Breakaway force was defined for the most favorable conditions, taking into account:
  • using a sheet made of mild steel, serving as a magnetic yoke
  • possessing a thickness of minimum 10 mm to ensure full flux closure
  • characterized by smoothness
  • without any clearance between the magnet and steel
  • under perpendicular force direction (90-degree angle)
  • in neutral thermal conditions

Impact of factors on magnetic holding capacity in practice

Effective lifting capacity is affected by working environment parameters, mainly (from priority):
  • Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, 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 penetrates through instead of generating force.
  • Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
  • Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
  • Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate lowers the holding force.

Safe handling of neodymium magnets
Swallowing risk

These products are not toys. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a critical condition and requires urgent medical intervention.

Thermal limits

Control the heat. Exposing the magnet to high heat will destroy its properties and pulling force.

Sensitization to coating

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease handling magnets and use protective gear.

Health Danger

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

Magnetic media

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

Shattering risk

Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Precision electronics

Note: rare earth magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.

Safe operation

Use magnets consciously. Their huge power can surprise even professionals. Stay alert and respect their power.

Physical harm

Danger of trauma: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Flammability

Powder generated during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
