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.

Grip strength weakens sharply with every mm of gap. Remember that even the smallest gap (e.g., dirt, varnish, veneer) noticeably weakens the grip. Neodymiums work strongest in perfect adhesion; gap nullifies the power. Notice how rapidly the parameters drop, when the product does not touch directly to the steel surface. When calculating the assembly, eliminate additional spacers.

The following data indicates the approximate force required to initiate the downward movement of the magnet downwards against a upright metal surface (assuming standard friction). This value is a function of the separation distance between the magnet and the surface.

When mounting a element on a upright surface (e.g., a car body), it will maintain just about 1/5 of its nominal power. Gravitational force and a low friction coefficient influence the fact that holders slide down faster than they pull off. Planning a wall mount? Remember that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the element will slip down under a much lighter cargo. Using a rubber coating can drastically increase the grip.

A too thin steel is incapable of absorb the entire magnetic field, which wastes potential of the holder. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze 100% of this neodymium's power, you require a sufficiently solid backing of metal. The saturation phenomenon means that on sheet metal structures (e.g., car bodies), the holder holds weaker. We advise picking the steel dimension based on the following data.

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly destroy this product. As the temperature rises, the magnet's force temporarily drops. Do not use this product close to heaters higher than its operating temperature limit. Ignoring the limit will cause permanent loss of magnetic properties.
*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) risk losing magnetic properties sooner than long magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnets attract each other from a significantly greater distance than a neodymium and metal setup. Such a system of magnet-to-magnet produces a massive flux and a larger range of operation. Planning to create a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when connecting a pair of magnets, the impact force is huge. The repulsion force is slightly lower than the attraction, but still significant.
*Field value for N-N configuration is approximately ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Estimates show shear force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a real danger to electronics as well as pacemakers. These NdFeB products produce a flux that destroys function of digital equipment. Remember: the invisible magnetic field passes through tissues and housings. Exceptional care must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

NdFeB products are very brittle – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Impact energy can destroy the magnet or injury to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A collision at high speed means shattering of the magnet. Use safety goggles when working with large magnets.

1. Wall mount (shear)

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

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) drastically reduces 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) = 1.31

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 presented product is a very strong rod magnet, composed of advanced NdFeB material, which, with dimensions of Ø4x10 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.32 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 typical 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 3.16 N with a weight of only 0.94 g, this cylindrical magnet 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 precision component. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Magnets N38 are suitable for 90% 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 (Ø4x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 4 mm and height 10 mm. The value of 3.16 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.94 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 4 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.

Pros and cons of neodymium magnets.

Advantages

Besides their immense field intensity, neodymium magnets offer the following advantages:
  • They retain full power for around ten years – the drop is just ~1% (based on simulations),
  • They feature excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
  • The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to present itself better,
  • The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Possibility of custom forming as well as optimizing to complex requirements,
  • Versatile presence in modern technologies – they are utilized in HDD drives, electric motors, diagnostic systems, as well as other advanced devices.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Limitations

Characteristics of disadvantages of neodymium magnets: application proposals
  • Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
  • Limited possibility of creating nuts in the magnet and complex forms - recommended is a housing - magnet mounting.
  • Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these devices are able to disrupt the diagnostic process medical after entering the body.
  • Due to expensive raw materials, their price is relatively high,

Lifting parameters

Maximum lifting capacity of the magnet – what it depends on?

Breakaway force was determined for ideal contact conditions, taking into account:
  • on a block made of mild steel, optimally conducting the magnetic flux
  • with a thickness minimum 10 mm
  • with an polished touching surface
  • without the slightest insulating layer between the magnet and steel
  • for force acting at a right angle (in the magnet axis)
  • at ambient temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

Bear in mind that the working load may be lower depending on elements below, starting with the most relevant:
  • Distance (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
  • Load vector – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Steel type – mild steel attracts best. Alloy steels lower magnetic permeability and holding force.
  • Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
  • Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.

Do not overheat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).

Warning for heart patients

Warning for patients: Powerful magnets affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Serious injuries

Big blocks can crush fingers instantly. Never put your hand betwixt two strong magnets.

Combustion hazard

Powder created during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Compass and GPS

Remember: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.

Eye protection

Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Caution required

Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Allergic reactions

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, refrain from direct skin contact or choose encased magnets.

Keep away from computers

Device Safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).

Keep away from children

Adult use only. Small elements can be swallowed, leading to intestinal necrosis. Store out of reach of children and animals.
