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 significantly with every subsequent millimeter of spacing. Remember that every additional insulation layer (e.g., contamination, paint, veneer) noticeably reduces the pull force. Neodymiums work most effectively at the point of direct contact; distance kills the power. Analyze how flashily the pull force plummet, when the magnet does not touch tightly to the metal substrate. When calculating the assembly, avoid redundant distances.

This section presents the estimated holding capacity needed to cause the shifting of the magnet vertically along a vertical steel plate (considering typical friction). The holding force depends on the separation distance between the magnet and the surface.

When placing a magnet on a vertical surface (e.g., a car body), it will maintain barely about 1/5 of its nominal power. Gravity as well as a weak degree of grip cause that magnets slip faster than they pull off. Want to create a wall mount? Note that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will give way down under a much lighter weight. Application of an anti-slip layer can drastically raise the stability.

A thin sheet is not enough to take in the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a thin surface, the flux will penetrate right through and the holding will be smaller. To squeeze the maximum of this neodymium's potential, you need a suitably thick backing of steel. The material oversaturation causes that on thin elements (e.g., thin profiles), the holder works worse. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products change their properties strength above the temperature limit. Protect against heat – high temperature can irreversibly demagnetize this magnet. With increasing heat, the neodymium's force temporarily drops. Do not use this magnet close to heaters higher than its safe range. Exceeding the critical threshold will cause permanent loss of magnetism.
*Engineering note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Thin magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two magnetic products interact from a significantly greater distance than a magnet and sheet setup. The connection of magnet-to-magnet generates a stronger field and a wider radius of action. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the collision energy is massive. The levitation is marginally weaker than the connection force, but still impressive.
*Flux density between like poles reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
Note: Results show sliding force of a pair of same magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a real danger to electronics as well as pacemakers. These NdFeB products produce a field that destroys function of digital equipment. Be aware: the unseen radiation acts through matter and glass. Special caution must be taken by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Neodymium magnets are very brittle – a violent impact against metal risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Kinetic force can destroy the magnet or injury to fingers. Always hold the magnet during installation so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when playing with powerful specimens.

1. Wall mount (shear)

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

2. Efficiency vs thickness

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

3. Heat tolerance

*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) = 0.79

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 extremely powerful cylinder magnet, composed of durable NdFeB material, which, with dimensions of Ø5x4 mm, guarantees the highest energy density. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.84 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 8.24 N with a weight of only 0.59 g, this rod is indispensable in electronics and wherever low weight is crucial.
Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø5x4), 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 5 mm and height 4 mm. The value of 8.24 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.59 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.
This cylinder is magnetized axially (along the height of 4 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Advantages

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They retain full power for almost ten years – the drop is just ~1% (according to analyses),
  • Neodymium magnets are exceptionally resistant to magnetic field loss caused by external magnetic fields,
  • In other words, due to the aesthetic layer of gold, the element gains visual value,
  • Neodymium magnets generate maximum magnetic induction on a their surface, which allows for strong attraction,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to versatility in shaping and the ability to adapt to complex applications,
  • Versatile presence in advanced technology sectors – they find application in computer drives, drive modules, medical devices, and industrial machines.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of neodymium magnets:
  • To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
  • Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
  • Limited possibility of making threads in the magnet and complex shapes - recommended is casing - magnet mounting.
  • Health risk resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

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

The force parameter is a result of laboratory testing executed under standard conditions:
  • on a base made of mild steel, effectively closing the magnetic flux
  • possessing a thickness of at least 10 mm to avoid saturation
  • characterized by even structure
  • with total lack of distance (no coatings)
  • under axial application of breakaway force (90-degree angle)
  • at temperature room level

Lifting capacity in real conditions – factors

During everyday use, the actual holding force is determined by many variables, listed from the most important:
  • Clearance – the presence of foreign body (rust, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
  • Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
  • 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 attracts identically. Alloy additives weaken the interaction with the magnet.
  • Smoothness – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Health Danger

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Serious injuries

Big blocks can smash fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.

Product not for children

These products are not suitable for play. Eating multiple magnets can lead to them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.

Mechanical processing

Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Demagnetization risk

Do not overheat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Sensitization to coating

A percentage of the population suffer from a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Frequent touching can result in a rash. It is best to wear safety gloves.

Do not underestimate power

Use magnets with awareness. Their immense force can surprise even experienced users. Stay alert and respect their force.

Magnetic media

Do not bring magnets close to a wallet, computer, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Threat to navigation

Remember: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, tablet, and navigation systems.
