Physical simulation of the product - report

The following data are the direct effect of a mathematical calculation. Results were calculated on models for the material Nd₂Fe₁₄B. Real-world conditions may differ from theoretical values. Treat these calculations as a reference point when designing systems.

Grip strength drops significantly with every mm of distance. Remember that even the smallest gap (e.g., contamination, paint, veneer) significantly reduces the pull force. Magnets operate optimally during direct contact; distance kills the power. Analyze how flashily the load capacity drop, when the magnet does not touch directly to the metal substrate. When planning the arrangement, eliminate unnecessary gaps.

This section indicates the estimated shear load necessary to cause the shifting of the magnet down against a upright steel plate (considering typical friction). This parameter is relative to the air gap between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 29x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	6.25 kg / 13.77 pounds 6246.0 g / 61.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.16 kg / 9.18 pounds 4164.0 g / 40.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.08 kg / 4.59 pounds 2082.0 g / 20.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	10.41 kg / 22.95 pounds 10410.0 g / 102.1 N

When mounting a magnet on a vertical wall (e.g., a fridge), it you can count on barely approx. 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient cause that magnets slide down faster than they detach. Want to create a vertical fastening? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the element will slide down under a noticeably lighter load. Application of an anti-slip layer can effectively increase the grip.

12 mm	100%	20.82 kg / 45.90 pounds 20820.0 g / 204.2 N

A too thin steel is incapable of take in the entire magnetic field, which squanders power of the holder. Should you attach a powerful product to a too thin substrate, the magnetism will pass right through and the holding will be smaller. To achieve the maximum of this neodymium's potential, you need a suitably thick piece of steel. The saturation phenomenon causes that on sheet metal structures (e.g., appliance housings), the magnet shows lower pull force. We suggest choosing the steel dimension from these parameters.

Classic neodymiums lose strength above the temperature limit. Watch out for overheating – heat can irreversibly damage this magnet. With every degree above norm, the magnet's power momentarily lowers. Avoid using this product close to ovens exceeding its operating temperature limit. Ignoring the limit will result in destruction of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (pancake types) risk losing magnetic properties under lower heat stress compared to rod magnets. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a much further distance than a magnet and steel setup. Such a system of magnet-to-magnet produces a massive flux and a further horizon of performance. Planning to create a strong closure? Apply two magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the collision energy is huge. The repulsion force is slightly lower than the connection force, but still impressive.
*Flux density between like poles is approximately ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Results apply to shear force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Hazards (electronics) - precautionary measures
MW 29x10 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	13.5 cm

Powerful magnet radiation is a large risk to electronic devices as well as pacemakers. These magnets produce a flux that disrupts operation of digital equipment. Notice: the unseen radiation acts through matter and housings. Increased vigilance must be taken by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - collision effects
MW 29x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	22.90 km/h (6.36 m/s)	1.00 J
30 mm	35.92 km/h (9.98 m/s)	2.47 J
50 mm	46.24 km/h (12.85 m/s)	4.09 J
100 mm	65.38 km/h (18.16 m/s)	8.17 J

NdFeB products are delicate – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when working with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet retains merely approx. 20-30% of its nominal pull.

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) significantly limits the holding force.

3. Power loss vs temp

*For N38 grade, 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) = 0.45

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 5x15 / N38 - cylindrical magnet

1.107 ZŁ brutto / pcs

This product is an exceptionally strong cylinder magnet, composed of modern NdFeB material, which, at dimensions of Ø29x10 mm, guarantees maximum efficiency. The MW 29x10 / N38 model is characterized by an accuracy of ±0.1mm and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 20.82 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 204.22 N with a weight of only 49.54 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability 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 the strongest magnets in the same volume (Ø29x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 29 mm and height 10 mm. The key parameter here is the lifting capacity amounting to approximately 20.82 kg (force ~204.22 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 10 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 through the diameter if your project requires it.

Pros and cons of Nd₂Fe₁₄B magnets.

Benefits

Besides their remarkable magnetic power, neodymium magnets offer the following advantages:

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
They are resistant to demagnetization induced by external field influence,
Thanks to the glossy finish, the coating of nickel, gold, or silver gives an professional appearance,
Neodymium magnets ensure maximum magnetic induction on a their surface, which ensures high operational effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
Possibility of exact creating as well as adapting to complex conditions,
Huge importance in modern industrial fields – they are commonly used in computer drives, motor assemblies, medical devices, and industrial machines.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

They are prone to damage upon heavy 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
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
We suggest cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small components of these magnets can disrupt the diagnostic process medical when they are in the body.
With large orders the cost of neodymium magnets can be a barrier,

Lifting parameters

Magnetic strength at its maximum – what it depends on?

Magnet power is the result of a measurement for optimal configuration, assuming:

using a plate made of high-permeability steel, serving as a circuit closing element
possessing a massiveness of min. 10 mm to avoid saturation
with an polished contact surface
under conditions of ideal adhesion (metal-to-metal)
for force acting at a right angle (in the magnet axis)
at standard ambient temperature

What influences lifting capacity in practice

Bear in mind that the magnet holding may be lower depending on elements below, in order of importance:

Air gap (betwixt the magnet and the metal), as even a tiny clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.

Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.

H&S for magnets

Electronic devices

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

Metal Allergy

A percentage of the population suffer from a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Extended handling may cause dermatitis. We strongly advise use protective gloves.

Permanent damage

Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Dust explosion hazard

Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.

Hand protection

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

Powerful field

Use magnets with awareness. Their immense force can surprise even professionals. Be vigilant and do not underestimate their power.

Risk of cracking

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

Danger to pacemakers

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

Keep away from electronics

Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
