Pulling power weakens significantly with every subsequent millimeter of distance. Note that even the smallest gap (e.g., contamination, paint, dust) noticeably reduces the pull force. Neodymiums operate optimally at the point of direct contact; distance nullifies the power. Analyze how quickly the pull force plummet, when the product does not touch flatly to the steel surface. When designing the assembly, avoid unnecessary gaps.

The table below presents the theoretical force needed to initiate the slippage of the magnet downwards along a vertical metal surface (assuming typical friction coefficient). This parameter depends on the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 70x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	29.95 kg / 66.03 pounds 29949.0 g / 293.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	19.97 kg / 44.02 pounds 19966.0 g / 195.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	9.98 kg / 22.01 pounds 9983.0 g / 97.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	49.92 kg / 110.04 pounds 49915.0 g / 489.7 N

When mounting a holder on a upright surface (e.g., a car body), it will maintain only approx. 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that products slide down easier than they pull off. Want to create a hanger? Note that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a much lighter load. Application of an anti-slip layer can effectively increase the grip.

5 mm	42%	41.60 kg / 91.70 pounds 41595.8 g / 408.1 N
10 mm	83%	83.19 kg / 183.41 pounds 83191.7 g / 816.1 N
11 mm	92%	91.51 kg / 201.75 pounds 91510.8 g / 897.7 N
12 mm	100%	99.83 kg / 220.09 pounds 99830.0 g / 979.3 N

A too thin steel is incapable of conduct the full magnetic flux, which wastes potential of the holder. If you attach a powerful product to a weak sheet, the flux will pass right through and the attraction force will be weaker. To achieve the maximum of this magnet's power, you require a sufficiently solid element of metal. The material oversaturation means that on thin elements (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel thickness according to the table below.

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Protect against heat – heat can irreversibly demagnetize this product. With increasing heat, the neodymium's force briefly drops. Avoid using this magnet near heat sources exceeding its working range. Ignoring the limit will result in permanent loss of magnetism.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low Pc) risk losing magnetic properties sooner than long magnets. Warning indicator in the table points to permanent field degradation for this particular item.

Two strong neodymiums interact from a much further distance than a neodymium and metal setup. The setup of magnet-to-magnet produces a massive flux and a larger range of action. Planning to create a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Remember that when connecting a pair of magnets, the collision energy is huge. The levitation is a bit weaker than the connection force, but still impressive.
*The magnetic induction in repulsion mode reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Important: Figures refer to sliding force of two matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - precautionary measures

A strong magnetic field is a large risk to electronics and pacemakers. These NdFeB products produce a flux that prevents correct functioning of sensitive medical devices. Remember: the unseen radiation acts through matter and housings. Special caution must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

MW 70x20 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	17.39 km/h (4.83 m/s)	6.73 J
30 mm	24.57 km/h (6.83 m/s)	13.45 J
50 mm	30.08 km/h (8.36 m/s)	20.15 J
100 mm	41.97 km/h (11.66 m/s)	39.23 J

Neodymium magnets are prone to chipping – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when playing with large magnets.

Corrosion 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. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains just a fraction of its max power.

2. Steel thickness impact

*Thin steel (e.g. computer case) significantly limits 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) = 0.39

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.

MW 8x10 / N38 - cylindrical magnet

1.501 ZŁ brutto / pcs

The presented product is a very strong cylindrical magnet, manufactured from modern NdFeB material, which, at dimensions of Ø70x20 mm, guarantees optimal power. The MW 70x20 / N38 component is characterized by an accuracy of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 99.83 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its triple-layer 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 modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 979.00 N with a weight of only 577.27 g, this cylindrical magnet is indispensable in miniature devices 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 epoxy glues. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø70x20), 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 Ø70x20 mm, which, at a weight of 577.27 g, makes it an element with high magnetic energy density. The value of 979.00 N means that the magnet is capable of holding a weight many times exceeding its own mass of 577.27 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 20 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.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Advantages

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

Their magnetic field remains stable, and after approximately ten years it decreases only by ~1% (according to research),
They retain their magnetic properties even under strong external field,
The use of an aesthetic layer 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 a distinguishing feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Possibility of exact shaping and modifying to specific needs,
Versatile presence in modern industrial fields – they find application in computer drives, electromotive mechanisms, medical equipment, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in small systems

Cons

What to avoid - cons of neodymium magnets and proposals for their use:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in producing nuts and complex shapes in magnets, we recommend using casing - magnetic mount.
Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these devices can complicate diagnosis medical when they are in 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

Breakaway strength of the magnet in ideal conditions – what affects it?

The force parameter is a theoretical maximum value performed under standard conditions:

with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
with a thickness no less than 10 mm
with an polished contact surface
under conditions of ideal adhesion (metal-to-metal)
for force applied at a right angle (pull-off, not shear)
at ambient temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

Bear in mind that the application force will differ influenced by elements below, starting with the most relevant:

Air gap (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of nominal force).
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.

Warnings

Handling rules

Handle with care. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can react.

Power loss in heat

Watch the temperature. Heating the magnet to high heat will destroy its magnetic structure and strength.

Warning for heart patients

For implant holders: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.

Crushing risk

Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!

Impact on smartphones

GPS units and smartphones are highly sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.

Protect data

Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).

Sensitization to coating

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid direct skin contact or choose encased magnets.

No play value

Neodymium magnets are not toys. Swallowing several magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates immediate surgery.

Eye protection

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

Dust is flammable

Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
