Magnetic force weakens drastically per each millimeter of spacing. Note that even a microscopic distance (e.g., contamination, varnish, rust) strongly weakens the grip. Neodymiums hold optimally at the point of direct contact; distance drastically cuts the power. See how quickly the parameters plummet, when the magnet does not touch directly to the metal substrate. When calculating the assembly, avoid additional spacers.

The table below calculates the theoretical holding capacity necessary to initiate the downward movement of the magnet vertically against a upright steel wall (considering standard friction). This parameter is a function of the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 70x60 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	49.18 kg / 108.42 lbs 49179.0 g / 482.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	32.79 kg / 72.28 lbs 32786.0 g / 321.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	16.39 kg / 36.14 lbs 16393.0 g / 160.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	81.97 kg / 180.70 lbs 81965.0 g / 804.1 N

When placing a magnet on a vertical wall (e.g., a board), it you can count on barely approx. 1/5 of its nominal power. Gravitational force and a low friction coefficient mean that magnets slide down easier than they pop off the substrate. Designing a hanger? Remember that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the holder will give way down under a significantly smaller load. Utilizing a rubberized coating can significantly improve the result.

5 mm	42%	68.30 kg / 150.58 lbs 68304.2 g / 670.1 N
10 mm	83%	136.61 kg / 301.17 lbs 136608.3 g / 1340.1 N
11 mm	92%	150.27 kg / 331.29 lbs 150269.2 g / 1474.1 N
12 mm	100%	163.93 kg / 361.40 lbs 163930.0 g / 1608.2 N

A too thin steel is not enough to focus the full magnetic flux, which weakens actual performance of the magnet. If you install a neodymium to a thin surface, the field will pass right through and the pull force will drop sharply. To utilize 100% of this magnet's potential, you require a sufficiently solid backing of steel. The saturation effect causes that on thin elements (e.g., thin profiles), the magnet shows lower pull force. We recommend selecting the steel dimension based on the following data.

100 °C	-28.8%	116.72 kg / 257.32 lbs 116718.2 g / 1145.0 N

Standard neodymium magnets irreversibly lose power above the temperature limit. Watch out for overheating – high temperature can permanently damage this magnet. As the temperature rises, the magnet's power momentarily drops. Do not use this magnet near heat sources higher than its working range. Exceeding the critical threshold will lead to irreversible degradation of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low Pc) may lose charge permanently sooner compared to rod magnets. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal setup. The connection of two magnets generates a stronger field and a further horizon of action. Designing a solid fastener? Apply two magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the impact force is huge. The repulsion force is marginally weaker than the connection force, but still large.
*Field value between like poles drops to ~0 Gs at the midpoint between the magnets (due to field cancellation).
Attention: Results demonstrate shear force of a pair of matching magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Safety (HSE) (implants) - precautionary measures
MW 70x60 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	42.0 cm
Hearing aid	10 Gs (1.0 mT)	33.0 cm

Powerful magnet radiation is a real danger to electronics and pacemakers. These magnets generate a flux that destroys function of digital equipment. Notice: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Dynamics (kinetic energy) - 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

NdFeB products are prone to chipping – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can trigger coating fragments or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when working with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

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

2. Plate thickness effect

*Thin steel (e.g. computer case) severely weakens the holding force.

3. Power loss vs temp

*For N38 material, 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

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.

8.35 ZŁ brutto / pcs

The presented product is an exceptionally strong rod magnet, composed of advanced NdFeB material, which, at dimensions of Ø70x60 mm, guarantees maximum efficiency. The MW 70x60 / N38 model is characterized by high dimensional repeatability and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 163.93 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 1608.16 N with a weight of only 1731.8 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., 70.1 mm) using epoxy glues. To ensure long-term durability in industry, 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 excessive miniaturization with maximum force is not required. If you need even stronger 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 store.

This model is characterized by dimensions Ø70x60 mm, which, at a weight of 1731.8 g, makes it an element with impressive 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 secures it against oxidation, 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 70 mm. 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 through the diameter if your project requires it.

Advantages and disadvantages of rare earth magnets.

Advantages

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

They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
They maintain their magnetic properties even under external field action,
In other words, due to the smooth layer of gold, the element gains a professional look,
The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Thanks to versatility in designing and the capacity to modify to individual projects,
Fundamental importance in modern technologies – they are commonly used in magnetic memories, drive modules, precision medical tools, and industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in miniature devices

Weaknesses

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
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 stability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Limited ability of creating threads in the magnet and complex shapes - recommended is a housing - mounting mechanism.
Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

The declared magnet strength concerns the peak performance, recorded under optimal environment, namely:

using a base made of mild steel, acting as a circuit closing element
with a thickness of at least 10 mm
with an polished contact surface
without any insulating layer between the magnet and steel
during detachment in a direction vertical to the mounting surface
at ambient temperature room level

Determinants of practical lifting force of a magnet

In practice, the actual lifting capacity is determined by several key aspects, presented from most significant:

Distance (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
Steel type – low-carbon steel attracts best. Higher carbon content decrease magnetic properties and holding force.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Rough surfaces weaken the grip.
Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the holding force.

Do not overheat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Product not for children

Always store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are tragic.

Safe operation

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Risk of cracking

NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets will cause them breaking into shards.

Medical implants

Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Finger safety

Large magnets can break fingers instantly. Under no circumstances place your hand between two strong magnets.

Avoid contact if allergic

Certain individuals suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Prolonged contact might lead to a rash. It is best to wear protective gloves.

Protect data

Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.

Threat to navigation

A powerful magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a smartphone to avoid breaking the sensors.

Do not drill into magnets

Dust created during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
