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 weakens drastically with every subsequent millimeter of spacing. Note that even the smallest gap (e.g., dirt, paint, veneer) strongly reduces the pull force. Neodymiums work optimally during direct contact; air break weakens the power. Analyze how quickly the parameters fall, when the product does not adhere flatly to the steel surface. When planning the mounting, eliminate unnecessary gaps.

The table below defines the estimated holding capacity required to cause the slippage of the magnet down on a upright steel plate (considering standard friction coefficient). This parameter varies with the separation distance between the magnet and the metal.

When placing a magnet on a upright wall (e.g., a board), it will only hold barely approx. 20%-30% of its maximum pull force. Gravity as well as a low friction coefficient influence the fact that magnets move down easier than they detach. Want to create a hanger? Remember that the shear force is much weaker than the maximum static pull force. On a painted metal, the magnet will slip down under a significantly smaller load. Utilizing a rubberized coating can drastically raise the stability.

A thin metal plate is incapable of focus the entire magnetic field, which wastes potential of the holder. Should you attach a powerful product to a too thin substrate, the field will pass right through and the holding will be smaller. To achieve full efficiency of this magnet's power, you need a suitably thick element of metal. The saturation effect means that on thin elements (e.g., appliance housings), the magnet shows lower pull force. We advise picking the steel thickness from these parameters.

Classic neodymiums irreversibly lose parameters after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly demagnetize this product. With increasing heat, the neodymium's force briefly drops. Refrain from using this product close to ovens exceeding its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetism.
*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures compared to rod magnets. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a much further distance than a magnet and sheet combination. The connection of two magnets generates a stronger field and a further horizon of performance. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the impact force is extreme. The levitation is marginally weaker than the connection force, but still significant.
*The magnetic induction for N-N configuration drops to ~0 Gs at the geometric center between the magnets (due to field cancellation).
Attention: Estimates show sliding force of dual matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a real danger to electronic devices and medical implants. These magnets produce a field that destroys function of digital equipment. Remember: the invisible magnetic field penetrates the body and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

NdFeB products are delicate – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can cause material chips or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear safety glasses when handling with powerful specimens.

1. Vertical hold

*Warning: On a vertical surface, the magnet holds merely ~20% of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) significantly limits the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.71

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 offered product is a very strong cylinder magnet, produced from durable NdFeB material, which, with dimensions of Ø15x10 mm, guarantees maximum efficiency. The MW 15x10 / N38 model features high dimensional repeatability and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 7.70 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, 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 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 75.51 N with a weight of only 13.25 g, this rod is indispensable in electronics 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 chipping the coating of this professional component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Magnets NdFeB grade N38 are strong enough 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 (Ø15x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 15 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 7.70 kg (force ~75.51 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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 15 mm. 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.

Advantages as well as disadvantages of rare earth magnets.

Pros

Apart from their superior magnetic energy, neodymium magnets have these key benefits:
  • Their power is durable, and after approximately ten years it drops only by ~1% (according to research),
  • They possess excellent resistance to magnetic field loss as a result of external fields,
  • The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
  • They feature high magnetic induction at the operating surface, which improves attraction properties,
  • Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
  • Thanks to flexibility in shaping and the ability to modify to client solutions,
  • Significant place in modern industrial fields – they serve a role in computer drives, electric motors, diagnostic systems, also multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in miniature devices

Weaknesses

Disadvantages of NdFeB magnets:
  • At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing nuts and complicated forms in magnets, we propose using a housing - magnetic mount.
  • Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to complicate diagnosis medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Best holding force of the magnet in ideal parameters – what contributes to it?

Holding force of 7.70 kg is a result of laboratory testing performed under the following configuration:
  • on a plate made of structural steel, effectively closing the magnetic field
  • possessing a thickness of at least 10 mm to avoid saturation
  • with a surface cleaned and smooth
  • under conditions of ideal adhesion (surface-to-surface)
  • during detachment in a direction vertical to the plane
  • in neutral thermal conditions

Key elements affecting lifting force

Please note that the application force will differ influenced by elements below, in order of importance:
  • Distance – existence of any layer (paint, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
  • Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
  • Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
  • Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
  • Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the lifting capacity.

Precautions when working with NdFeB magnets
Phone sensors

A strong magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.

Mechanical processing

Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.

Sensitization to coating

Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.

Protective goggles

NdFeB magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.

Danger to the youngest

Always keep magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are life-threatening.

ICD Warning

Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

Data carriers

Intense magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.

Do not overheat magnets

Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Powerful field

Use magnets with awareness. Their huge power can surprise even professionals. Be vigilant and do not underestimate their force.

Pinching danger

Danger of trauma: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
