Magnetic force decreases sharply per each millimeter of distance. Remember that even a very thin break (e.g., contamination, paint, rust) strongly reduces the pull force. Magnetic products operate most effectively in perfect adhesion; gap weakens the force. See how rapidly the pull force drop, when the magnet does not adhere directly to the metal substrate. When calculating the mounting, avoid unnecessary gaps.

The table below calculates the approximate shear load required to start the shifting of the magnet down along a upright metal surface (assuming standard friction coefficient). This parameter depends on the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 70x50 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	50.46 kg / 111.25 LBS 50463.0 g / 495.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	33.64 kg / 74.17 LBS 33642.0 g / 330.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	16.82 kg / 37.08 LBS 16821.0 g / 165.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	84.11 kg / 185.42 LBS 84105.0 g / 825.1 N

When hanging a magnet on a vertical surface (e.g., a board), it will only hold only approx. 1/5 of nominal attraction strength. Gravity and a low friction coefficient cause that products slide down easier than they pull off. Want to create a wall mount? Note that the shear force is much weaker than the maximum static pull force. On a slippery surface, the holder will slip down under a significantly smaller load. Utilizing a rubberized coating can significantly increase the grip.

A thin metal plate is incapable of take in the entire magnetic field, which weakens actual performance of the magnet. Should you attach a powerful product to a weak sheet, the flux will penetrate right through and the attraction force will be weaker. To squeeze full efficiency of this neodymium's potential, you need a suitably thick element of steel. The saturation effect means that on delicate walls (e.g., car bodies), the holder holds weaker. We advise picking the steel thickness based on the following data.

Standard neodymium magnets irreversibly lose parameters above the temperature limit. Watch out for overheating – excessive heat can irreversibly destroy this magnet. As the temperature rises, the magnet's power briefly decreases. Refrain from using this product in hot environments exceeding its working range. Too high temperature will cause irreversible degradation of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) are more susceptible to demagnetization under lower heat stress compared to rod magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two magnets attract each other from a significantly greater distance than a neodymium and metal setup. The connection of magnet-to-magnet generates a stronger field and a larger range of performance. Designing a strong closure? Apply two magnets instead of one magnet and a steel. Be careful that when connecting a pair of magnets, the pinch force is massive. The levitation is a bit weaker than the attraction, but still significant.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the midpoint between the magnets (due to field cancellation).
Note: Calculations apply to friction force of two identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Protective zones (implants) - precautionary measures
MW 70x50 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	40.0 cm
Hearing aid	10 Gs (1.0 mT)	31.5 cm

Payment card	400 Gs (40.0 mT)	7.5 cm
HDD hard drive	600 Gs (60.0 mT)	6.0 cm

Powerful magnet radiation is a serious hazard to electronics and pacemakers. These magnets produce a flux that destroys function of sensitive medical devices. Notice: the unseen radiation penetrates the body and plastic. Special caution must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - collision effects
MW 70x50 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	13.97 km/h (3.88 m/s)	10.87 J
30 mm	20.06 km/h (5.57 m/s)	22.40 J
50 mm	24.70 km/h (6.86 m/s)	33.96 J
100 mm	34.46 km/h (9.57 m/s)	66.12 J

Magnetic elements are delicate – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the neodymium. Wear safety glasses when playing with powerful specimens.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Caution: On a vertical surface, the magnet holds only a fraction of its max power.

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) significantly 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 P_c (Permeance Coefficient) = 0.74

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.

The presented product is an exceptionally strong cylindrical magnet, composed of durable NdFeB material, which, with dimensions of Ø70x50 mm, guarantees maximum efficiency. The MW 70x50 / N38 component is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 168.21 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 1650.14 N with a weight of only 1443.17 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are suitable 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 (Ø70x50), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø70x50 mm, which, at a weight of 1443.17 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 168.21 kg (force ~1650.14 N), which, with such compact dimensions, proves the high power of the NdFeB material. 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 diametrically if your project requires it.

Strengths and weaknesses of rare earth magnets.

Strengths

Besides their remarkable field intensity, neodymium magnets offer the following advantages:

Their strength is durable, and after around 10 years it drops only by ~1% (according to research),
Magnets effectively protect themselves against demagnetization caused by ambient magnetic noise,
In other words, due to the reflective surface of nickel, the element becomes visually attractive,
The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
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...
Thanks to versatility in forming and the capacity to modify to unusual requirements,
Versatile presence in modern industrial fields – they are commonly used in data components, drive modules, medical devices, and industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems

Disadvantages

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

To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
Neodymium magnets lose their power 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
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited ability of making threads in the magnet and complex forms - recommended is cover - magnetic holder.
Health risk resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to complicate diagnosis medical after entering the body.
With mass production the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum magnetic pulling force – what contributes to it?

The force parameter is a result of laboratory testing performed under specific, ideal conditions:

on a base made of structural steel, optimally conducting the magnetic field
whose transverse dimension reaches at least 10 mm
characterized by lack of roughness
with total lack of distance (without impurities)
under axial application of breakaway force (90-degree angle)
in stable room temperature

Determinants of practical lifting force of a magnet

In practice, the actual holding force results from a number of factors, ranked from crucial:

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
Surface finish – ideal contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate lowers the holding force.

H&S for magnets

Allergic reactions

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, refrain from direct skin contact and select encased magnets.

Maximum temperature

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Handling guide

Handle magnets consciously. Their huge power can shock even professionals. Be vigilant and respect their force.

Do not drill into magnets

Mechanical processing of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

This is not a toy

Adult use only. Small elements pose a choking risk, leading to serious injuries. Store out of reach of children and animals.

Electronic hazard

Do not bring magnets near a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.

GPS and phone interference

GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.

Pinching danger

Watch your fingers. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!

Material brittleness

Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Danger to pacemakers

For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to work with the magnets.
