Magnetic force drops drastically per each millimeter of distance. Remember that even a very thin break (e.g., contamination, paint, rust) noticeably weakens the grip. Neodymiums operate most effectively during direct contact; air break weakens the force. Observe how quickly the parameters plummet, when the product does not adhere flatly to the steel surface. When calculating the mounting, discard additional spacers.

The following data presents the approximate force necessary to cause the shifting of the magnet downwards against a vertical steel plate (considering typical friction coefficient). This parameter is a function of the separation distance between the magnet and the metal.

When placing a holder on a upright wall (e.g., a car body), it will only hold only approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip influence the fact that products slip easier than they pull off. Planning a hanger? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a noticeably lighter load. Using a rubber pad can drastically increase the grip.

A thin metal plate is not enough to absorb the entire magnetic field, which wastes potential of the magnet. If you install a neodymium to a too thin substrate, the magnetism will pass right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's power, you require a sufficiently solid element of steel. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the magnet holds weaker. We suggest choosing the steel cross-section from these parameters.

Ordinary NdFeB products lose strength after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly destroy this product. As the temperature rises, the neodymium's force briefly drops. Avoid using this magnet near heat sources exceeding its working range. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Technical advisory: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures compared to rod magnets. Red status in the table signals permanent field degradation for this particular item.

Two strong neodymiums interact from a much further distance than a neodymium and metal combination. Such a system of two magnets creates a more powerful interaction and a larger range of operation. Want to build a strong closure? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the impact force is extreme. The levitation is slightly lower than the attraction, but still impressive.
*Flux density in repulsion mode drops to ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Note: Calculations apply to sliding force of dual same neodymium magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a serious hazard to electronic devices as well as pacemakers. These magnets generate a field that destroys function of digital equipment. Notice: the invisible magnetic field passes through tissues and glass. Exceptional care must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - warning
MW 8x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	22.32 km/h (6.20 m/s)	0.07 J
30 mm	38.59 km/h (10.72 m/s)	0.22 J
50 mm	49.82 km/h (13.84 m/s)	0.36 J
100 mm	70.46 km/h (19.57 m/s)	0.72 J

Magnetic elements are prone to chipping – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when playing with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Warning: On a vertical wall, the magnet retains merely approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

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

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.00

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 P_c (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 P_c 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 exceptionally strong cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø8x10 mm, guarantees the highest energy density. This specific item features an accuracy of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 1.84 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 18.00 N with a weight of only 3.77 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using epoxy glues. To ensure long-term durability in automation, anaerobic resins 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 operational stability. If you need even stronger magnets in the same volume (Ø8x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø8x10 mm, which, at a weight of 3.77 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 1.84 kg (force ~18.00 N), which, with such compact dimensions, proves the high power of the NdFeB material. 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 10 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard 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.

Advantages

Apart from their superior power, neodymium magnets have these key benefits:

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
They feature excellent resistance to magnetism drop when exposed to opposing magnetic fields,
In other words, due to the smooth finish of nickel, the element looks attractive,
Magnetic induction on the top side of the magnet is very high,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
Thanks to versatility in shaping and the capacity to modify to specific needs,
Fundamental importance in innovative solutions – they are commonly used in computer drives, motor assemblies, advanced medical instruments, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in miniature devices

Weaknesses

Problematic aspects of neodymium magnets and ways of using them

To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
Neodymium magnets decrease their strength 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
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
We recommend a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical when they are in the body.
Due to neodymium price, their price is higher than average,

Lifting parameters

Maximum magnetic pulling force – what affects it?

The declared magnet strength represents the maximum value, obtained under laboratory conditions, meaning:

using a sheet made of low-carbon steel, serving as a circuit closing element
with a cross-section no less than 10 mm
characterized by smoothness
under conditions of ideal adhesion (surface-to-surface)
during detachment in a direction perpendicular to the plane
at standard ambient temperature

Magnet lifting force in use – key factors

Real force impacted by working environment parameters, mainly (from priority):

Distance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Direction of force – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Precautions when working with neodymium magnets

Do not drill into magnets

Fire hazard: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.

Power loss in heat

Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and strength.

Sensitization to coating

It is widely known that nickel (the usual finish) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands and choose coated magnets.

Keep away from electronics

Remember: neodymium magnets produce a field that confuses sensitive sensors. Maintain a separation from your phone, tablet, and GPS.

No play value

Neodymium magnets are not toys. Swallowing several magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.

Electronic devices

Data protection: Strong magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).

Crushing force

Watch your fingers. Two large magnets will join instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Powerful field

Exercise caution. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can move away.

Medical implants

For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Magnet fragility

Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
