Technical analysis of the magnet - report

The following values are the direct effect of a mathematical calculation. Values rely on algorithms for the material Nd₂Fe₁₄B. Operational parameters might slightly differ from theoretical values. Please consider these calculations as a preliminary roadmap for designers.

Pulling power drops significantly per each millimeter of distance. Remember that even the smallest gap (e.g., contamination, paint, dust) noticeably diminishes the holding power. Neodymiums work strongest during direct contact; gap kills the force. Observe how quickly the parameters plummet, when the magnet does not adhere tightly to the metal substrate. When designing the assembly, eliminate redundant distances.

Table 2: Slippage capacity (wall)
MW 2x10 / N38

Distance (mm)	Friction coefficient	Pull Force (kg)
0 mm	Stal (~0.2)	0.01 kg / 14.0 g 0.1 N

30 mm	Stal (~0.2)	0.00 kg / 0.0 g 0.0 N
50 mm	Stal (~0.2)	0.00 kg / 0.0 g 0.0 N

The following data indicates the theoretical force sufficient to cause the shifting of the magnet downwards against a vertical steel plate (assuming typical friction). The holding force depends on the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 2x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.02 kg / 21.0 g 0.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.01 kg / 14.0 g 0.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.01 kg / 7.0 g 0.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.04 kg / 35.0 g 0.3 N

When hanging a element on a vertical wall (e.g., a fridge), it you can count on just approx. 20%-30% of nominal attraction strength. Gravity as well as a low friction coefficient influence the fact that magnets slip faster than they pull off. Designing a hanger? Note that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a noticeably lighter cargo. Application of an anti-slip pad can significantly increase the grip.

Table 4: Steel thickness (substrate influence) - sheet metal selection
MW 2x10 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.01 kg / 7.0 g 0.1 N
1 mm	25%	0.02 kg / 17.5 g 0.2 N
2 mm	50%	0.04 kg / 35.0 g 0.3 N
5 mm	100%	0.07 kg / 70.0 g 0.7 N
10 mm	100%	0.07 kg / 70.0 g 0.7 N

A thin metal plate is not enough to absorb the full magnetic flux, which wastes potential of the magnet. If you install a neodymium to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To utilize the maximum of this neodymium's power, you require a sufficiently solid piece of metal. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the product holds weaker. We recommend selecting the steel dimension based on the following data.

Table 5: Working in heat (material behavior) - thermal limit
MW 2x10 / N38

Ambient temp. (°C)	Power loss	Remaining pull	Status
20 °C	0.0%	0.07 kg / 70.0 g 0.7 N	OK
40 °C	-2.2%	0.07 kg / 68.5 g 0.7 N	OK
60 °C	-4.4%	0.07 kg / 66.9 g 0.7 N	OK
80 °C	-6.6%	0.07 kg / 65.4 g 0.6 N
100 °C	-28.8%	0.05 kg / 49.8 g 0.5 N

Ordinary NdFeB products lose power after exceeding the maximum temperature. Avoid high temperatures – heat can permanently demagnetize this magnet. With increasing heat, the neodymium's power briefly drops. Avoid using this product in hot environments exceeding its operating temperature limit. Ignoring the limit will lead to irreversible degradation of magnetic properties.

*Important note: Temperature resistance is determined by both grade, as well as the dimension ratios. Flat magnets (pancake types) are more susceptible to demagnetization at lower temperatures than taller cylinders. The danger warning in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a much further distance than a magnet and sheet setup. The setup of magnet-to-magnet produces a massive flux and a wider radius of operation. Planning to create a strong closure? Use a pair of magnets instead of one magnet and a steel. Be careful that when attracting two neodymiums, the pinch force is huge. The repulsion force is marginally weaker than the attraction, but still large.
*Flux density for N-N configuration is approximately ~0 Gs at the geometric center between the magnets (resulting from vector opposition).

Table 7: Safety (HSE) (implants) - warnings
MW 2x10 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	2.0 cm

Powerful magnet radiation poses a serious hazard to electronics as well as pacemakers. These magnets generate a flux that disrupts operation of digital equipment. Notice: the invisible magnetic field passes through tissues and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - collision effects
MW 2x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	17.22 km/h (4.78 m/s)	0.00 J
30 mm	29.83 km/h (8.29 m/s)	0.01 J
50 mm	38.51 km/h (10.70 m/s)	0.01 J
100 mm	54.47 km/h (15.13 m/s)	0.03 J

NdFeB products are delicate – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can cause material chips or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the neodymium. Use safety goggles when playing with powerful specimens.

Environment	Effective steel pull	Effect
Air (land)	0.07 kg	Standard
Water (riverbed)	0.08 kg (+0.01 kg Buoyancy gain)	+14.5%

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

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Sliding resistance

*Caution: On a vertical surface, the magnet retains merely a fraction of its nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) drastically limits 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) = 1.55

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.

MW 4x4 / N38 - cylindrical magnet

0.406 ZŁ brutto / pcs

The presented product is a very strong cylinder magnet, composed of advanced NdFeB material, which, at dimensions of Ø2x10 mm, guarantees optimal power. The MW 2x10 / N38 model boasts a tolerance 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. 0.07 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 0.70 N with a weight of only 0.24 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. 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.

Magnets N38 are suitable for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø2x10), 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 Ø2x10 mm, which, at a weight of 0.24 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 0.07 kg (force ~0.70 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, 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 2 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.

Strengths as well as weaknesses of rare earth magnets.

Advantages

Besides their immense pulling force, neodymium magnets offer the following advantages:

Their strength is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
They are extremely resistant to demagnetization induced by external field influence,
The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnetic induction on the top side of the magnet remains impressive,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to flexibility in forming and the ability to adapt to complex applications,
Significant place in modern industrial fields – they are commonly used in computer drives, motor assemblies, precision medical tools, also technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems

Disadvantages

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and 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 prevent oxidation and corrosion.
Limited possibility of creating nuts in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
Health risk to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these devices can complicate diagnosis medical in case of swallowing.
Due to neodymium price, their price is relatively high,

Pull force analysis

Maximum holding power of the magnet – what contributes to it?

The lifting capacity listed is a theoretical maximum value conducted under standard conditions:

on a block made of mild steel, optimally conducting the magnetic flux
possessing a thickness of at least 10 mm to ensure full flux closure
with a surface free of scratches
under conditions of gap-free contact (metal-to-metal)
during detachment in a direction vertical to the plane
at conditions approx. 20°C

Determinants of practical lifting force of a magnet

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

Air gap (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Material type – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of neodymium magnets

Implant safety

People with a ICD have to keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the implant.

Physical harm

Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Do not give to children

These products are not suitable for play. Swallowing multiple magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates immediate surgery.

Mechanical processing

Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Material brittleness

Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

GPS Danger

Be aware: rare earth magnets generate a field that confuses sensitive sensors. Keep a separation from your mobile, device, and navigation systems.

Data carriers

Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.

Handling rules

Exercise caution. Neodymium magnets act from a distance and snap with massive power, often quicker than you can move away.

Warning for allergy sufferers

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.

Do not overheat magnets

Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
