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.

Magnetic force weakens sharply with every mm of gap. Keep in mind that every additional insulation layer (e.g., contamination, paint, veneer) strongly weakens the grip. Magnets work most effectively during direct contact; distance drastically cuts the force. Observe how quickly the parameters drop, when the magnet does not adhere tightly to the metal substrate. When planning the mounting, avoid unnecessary gaps.

This section defines the theoretical weight limit necessary to start the shifting of the magnet down against a vertical metal surface (considering typical friction coefficient). This value is a function of the distance between the magnet and the metal.

When mounting a holder on a vertical wall (e.g., a fridge), it will maintain barely approx. 1/5 of its nominal power. Gravity as well as a weak degree of grip cause that magnets slip easier than they detach. Want to create a wall mount? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a noticeably lighter weight. Utilizing a rubberized pad can effectively improve the result.

A too thin steel cannot take in the full magnetic flux, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the field will pass right through and the pull force will drop sharply. To squeeze the maximum of this magnet's potential, you require a sufficiently solid piece of steel. The saturation effect causes that on sheet metal structures (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel dimension from these parameters.

Ordinary NdFeB products change their properties parameters above the temperature limit. Avoid high temperatures – excessive heat can irreversibly demagnetize this magnet. With increasing heat, the magnet's power temporarily lowers. Avoid using this magnet near heat sources exceeding its safe range. Too high temperature will cause destruction of magnetic properties.
*Engineering note: Heat tolerance is determined by both grade, but also on the magnet's shape. Thin magnets (low Pc) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Warning indicator in the table points to permanent field degradation for this particular item.

Two magnetic products interact from a wider radius than a magnet and steel combination. Such a system of two magnets creates a more powerful interaction and a larger range of action. Designing a strong closure? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the pinch force is extreme. The levitation is a bit weaker than the connection force, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Attention: Calculations apply to sliding force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a serious hazard to electronics and pacemakers. These neodymiums generate a field that prevents correct functioning of digital equipment. Notice: the unseen radiation passes through tissues and glass. Special caution must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are prone to chipping – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Use safety goggles when playing with large magnets.

Rust risk: 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. Vertical hold

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

2. Steel saturation

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

3. Temperature resistance

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.38

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 incredibly powerful rod magnet, composed of modern NdFeB material, which, with dimensions of Ø5x15 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 0.48 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 4.68 N with a weight of only 2.21 g, this rod is indispensable in electronics and wherever every gram matters.
Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Magnets N38 are strong enough for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø5x15), 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 15 mm. The value of 4.68 N means that the magnet is capable of holding a weight many times exceeding its own mass of 2.21 g. The product has a [NiCuNi] coating, which secures it 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 5 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 through the diameter if your project requires it.

Pros and cons of rare earth magnets.

Benefits

Besides their remarkable strength, neodymium magnets offer the following advantages:
  • They do not lose power, even over approximately ten years – the reduction in power is only ~1% (theoretically),
  • Neodymium magnets are distinguished by extremely resistant to loss of magnetic properties caused by external magnetic fields,
  • Thanks to the shiny finish, the surface of nickel, gold, or silver gives an aesthetic appearance,
  • Magnets are characterized by exceptionally strong magnetic induction on the working surface,
  • Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
  • Thanks to versatility in designing and the capacity to modify to specific needs,
  • Fundamental importance in modern technologies – they are utilized in hard drives, electromotive mechanisms, precision medical tools, also complex engineering applications.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Drawbacks and weaknesses of neodymium magnets: tips and applications.
  • To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
  • Neodymium magnets lose 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 stability even at temperatures up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
  • Limited possibility of making threads in the magnet and complex shapes - recommended is casing - mounting mechanism.
  • Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small components of these products can complicate diagnosis medical when they are in the body.
  • Due to complex production process, their price is relatively high,

Pull force analysis

Detachment force of the magnet in optimal conditions – what it depends on?

Holding force of 0.48 kg is a measurement result conducted under standard conditions:
  • on a plate made of mild steel, perfectly concentrating the magnetic field
  • with a cross-section no less than 10 mm
  • with a plane cleaned and smooth
  • without any air gap between the magnet and steel
  • under perpendicular force direction (90-degree angle)
  • at temperature room level

What influences lifting capacity in practice

During everyday use, the actual holding force is determined by several key aspects, presented from most significant:
  • Clearance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
  • Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
  • Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
  • Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
  • Temperature – temperature increase results in weakening of induction. Check the maximum operating temperature 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 attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate lowers the holding force.

Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Do not underestimate power

Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Eye protection

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.

Data carriers

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

Dust is flammable

Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.

Skin irritation risks

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, immediately stop working with magnets and wear gloves.

Finger safety

Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Pacemakers

People with a ICD must maintain an large gap from magnets. The magnetic field can interfere with the functioning of the implant.

Threat to navigation

A strong magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a device to avoid breaking the sensors.

Danger to the youngest

Strictly keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are fatal.
