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 the smallest gap (e.g., contamination, paint, veneer) significantly weakens the grip. Magnetic products hold strongest during direct contact; air break kills the power. Notice how quickly the load capacity drop, when the product does not touch flatly to the metal substrate. When designing the assembly, eliminate redundant distances.

When hanging a holder on a upright wall (e.g., a board), it will maintain only about 20%-30% of its maximum pull force. Gravitational force as well as a weak degree of grip cause that magnets slide down faster than they pull off. Want to create a vertical fastening? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the element will slide down under a much lighter weight. Using a rubber pad can effectively increase the grip.

A thin metal plate cannot take in the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a thin surface, the field will pass right through and the attraction force will be weaker. To utilize the maximum of this magnet's potential, you require a sufficiently solid backing of metal. The saturation phenomenon means that on thin elements (e.g., appliance housings), the holder works worse. We suggest choosing the steel cross-section according to the table below.

Ordinary NdFeB products change their properties strength above the temperature limit. Protect against heat – excessive heat can permanently damage this product. As the temperature rises, the neodymium's force briefly drops. Do not use this product in hot environments higher than its working range. Ignoring the limit will result in irreversible degradation of magnetic properties.
*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties sooner than long magnets. Red status in the table points to permanent field degradation for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and steel combination. Such a system of magnet-to-magnet generates a stronger field and a wider radius of action. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the pinch force is huge. The repulsion force is slightly lower than the connection force, but still large.
*The magnetic induction for N-N configuration drops to ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Attention: Calculations demonstrate sliding force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a large risk to electronic devices as well as medical implants. These NdFeB products produce a field that disrupts operation of sensitive medical devices. Be aware: the unseen radiation acts through matter and plastic. Special caution must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Neodymium magnets are delicate – a collision with steel causes immediate chipping. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can cause material chips or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear safety glasses when playing 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.
Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Caution: On a vertical wall, the magnet retains only ~20% of its nominal pull.

2. Plate thickness effect

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

3. Temperature resistance

*For N38 material, the critical limit is 80°C.

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

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

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 an extremely powerful cylindrical magnet, composed of durable NdFeB material, which, at dimensions of Ø45x25 mm, guarantees the highest energy density. The MW 45x25 / N38 model is characterized by a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 67.33 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
This model is perfect for building generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 660.51 N with a weight of only 298.21 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.
Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. 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.
Magnets NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest 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 store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 45 mm and height 25 mm. The key parameter here is the lifting capacity amounting to approximately 67.33 kg (force ~660.51 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 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.

Pros as well as cons of Nd2Fe14B magnets.

Advantages

Besides their immense pulling force, neodymium magnets offer the following advantages:
  • They do not lose magnetism, even after nearly 10 years – the decrease in lifting capacity is only ~1% (based on measurements),
  • They feature excellent resistance to magnetic field loss as a result of external fields,
  • By using a smooth coating of nickel, the element presents an proper look,
  • Magnets have extremely high magnetic induction on the outer side,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
  • Possibility of detailed machining as well as adapting to defined applications,
  • Huge importance in high-tech industry – they are used in computer drives, brushless drives, medical equipment, also technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in miniature devices

Cons

Characteristics of disadvantages 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 improves its resistance to damage
  • We warn that neodymium magnets can lose 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. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
  • We recommend a housing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
  • Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products can complicate diagnosis medical in case of swallowing.
  • With large orders the cost of neodymium magnets is a challenge,

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

Breakaway force is the result of a measurement for ideal contact conditions, assuming:
  • with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
  • with a cross-section of at least 10 mm
  • with an ground touching surface
  • without the slightest clearance between the magnet and steel
  • during detachment in a direction vertical to the plane
  • at conditions approx. 20°C

Magnet lifting force in use – key factors

Holding efficiency impacted by specific conditions, such as (from most important):
  • Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Load vector – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
  • Chemical composition of the base – mild steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
  • Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
  • Temperature – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.

Safe handling of NdFeB magnets
Warning for allergy sufferers

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease working with magnets and use protective gear.

Electronic devices

Equipment safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, timepieces).

Keep away from children

Product intended for adults. Tiny parts can be swallowed, causing serious injuries. Store away from children and animals.

Dust explosion hazard

Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Handling rules

Be careful. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can react.

Physical harm

Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Be careful!

Implant safety

Patients with a heart stimulator should keep an safe separation from magnets. The magnetic field can disrupt the operation of the implant.

Shattering risk

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

Operating temperature

Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).

Precision electronics

Remember: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
