Pulling power decreases drastically per each millimeter of spacing. Keep in mind that even the smallest gap (e.g., contamination, paint, dust) strongly weakens the grip. Neodymiums hold optimally during direct contact; air break drastically cuts the power. Observe how flashily the parameters plummet, when the magnet does not adhere flatly to the metal substrate. When designing the mounting, avoid redundant distances.

The table below shows the estimated holding capacity needed to cause the shifting of the magnet vertically on a upright steel wall (considering standard friction). This value is a function of the separation distance between the magnet and the surface.

When mounting a holder on a upright plane (e.g., a car body), it will only hold barely about 1/5 of its maximum pull force. Gravity as well as a weak degree of grip cause that holders move down faster than they pull off. Designing a vertical fastening? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will give way down under a significantly smaller load. Using a rubber coating can significantly improve the result.

A thin metal plate cannot absorb the entire magnetic field, which squanders power of the magnet. If you install a neodymium to a thin surface, the flux will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this neodymium's potential, you require a sufficiently solid backing of metal. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the holder works worse. We advise picking the steel cross-section based on the following data.

Standard neodymium magnets lose parameters after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently damage this magnet. With increasing heat, the neodymium's power momentarily decreases. Avoid using this product near heat sources exceeding its operating temperature limit. Ignoring the limit will result in permanent loss of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod magnets. Red status in the table indicates permanent field degradation for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet combination. Such a system of magnet-to-magnet creates a more powerful interaction and a wider radius of operation. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is extreme. The repulsion force is a bit weaker than the attraction, but still large.
*Field value between like poles reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Attention: Figures apply to sliding force of dual identical magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to electronics and medical implants. These magnets produce a field that destroys function of sensitive medical devices. Be aware: the invisible magnetic field passes through tissues and glass. Exceptional care must be taken by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Collisions (cracking risk) - collision effects
MW 70x60 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	12.58 km/h (3.49 m/s)	10.57 J
30 mm	18.09 km/h (5.02 m/s)	21.86 J
50 mm	22.27 km/h (6.19 m/s)	33.13 J
100 mm	31.06 km/h (8.63 m/s)	64.44 J

Magnetic elements are delicate – a strong collision with metal can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when handling with large magnets.

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Sliding resistance

*Caution: On a vertical surface, the magnet retains just ~20% of its nominal pull.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) significantly reduces the holding force.

3. Thermal stability

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.82

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 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.

This product is an incredibly powerful rod magnet, made from modern NdFeB material, which, at dimensions of Ø70x60 mm, guarantees the highest energy density. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 163.93 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 1608.16 N with a weight of only 1731.8 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 70.1 mm) using two-component epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets N38 are strong enough for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø70x60), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø70x60 mm, which, at a weight of 1731.8 g, makes it an element with high magnetic energy density. The value of 1608.16 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1731.8 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 60 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.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Strengths

Besides their durability, neodymium magnets are valued for these benefits:

Their power is durable, and after approximately 10 years it drops only by ~1% (according to research),
They show high resistance to demagnetization induced by external field influence,
Thanks to the smooth finish, the layer of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
Magnetic induction on the working layer of the magnet remains very high,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Due to the potential of flexible molding and customization to individualized requirements, magnetic components can be produced in a wide range of forms and dimensions, which makes them more universal,
Significant place in high-tech industry – they are utilized in hard drives, electromotive mechanisms, diagnostic systems, as well as modern systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

What to avoid - cons of neodymium magnets: weaknesses and usage proposals

At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in producing nuts and complex shapes in magnets, we propose using casing - magnetic holder.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Highest magnetic holding force – what contributes to it?

The load parameter shown refers to the maximum value, measured under optimal environment, namely:

on a block made of structural steel, perfectly concentrating the magnetic flux
whose thickness reaches at least 10 mm
with a plane free of scratches
without the slightest air gap between the magnet and steel
during pulling in a direction perpendicular to the plane
at standard ambient temperature

Magnet lifting force in use – key factors

Real force impacted by specific conditions, mainly (from most important):

Distance – existence of any layer (rust, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
Steel grade – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Precautions when working with NdFeB magnets

Health Danger

People with a ICD have to maintain an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.

Avoid contact if allergic

It is widely known that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, prevent touching magnets with bare hands and choose versions in plastic housing.

Handling guide

Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.

Dust explosion hazard

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

Electronic devices

Avoid bringing magnets close to a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.

Do not give to children

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

Magnetic interference

Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Risk of cracking

Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Thermal limits

Keep cool. NdFeB magnets are sensitive to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Crushing force

Protect your hands. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
