Physical analysis of the product - report

The following values constitute the outcome of a physical simulation. Values were calculated on algorithms for the class Nd₂Fe₁₄B. Operational conditions might slightly differ. Treat these calculations as a reference point when designing systems.

50 mm	11 Gs 1.1 mT	0.00 kg / 0.00 LBS 0.1 g / 0.0 N	weak grip

Grip strength weakens significantly with every subsequent millimeter of distance. Remember that even a microscopic distance (e.g., dirt, varnish, dust) significantly diminishes the holding power. Magnetic products work optimally at the point of direct contact; gap drastically cuts the power. See how quickly the pull force plummet, when the magnet does not adhere tightly to the steel surface. When designing the mounting, discard redundant distances.

This section shows the estimated shear load required to initiate the shifting of the magnet down along a upright metal surface (assuming standard friction). This parameter is a function of the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 16x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.33 kg / 2.93 LBS 1329.0 g / 13.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.89 kg / 1.95 LBS 886.0 g / 8.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.44 kg / 0.98 LBS 443.0 g / 4.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.22 kg / 4.88 LBS 2215.0 g / 21.7 N

When placing a element on a upright plane (e.g., a board), it will maintain just approx. 20%-30% of nominal attraction strength. Gravitational force as well as a weak degree of grip mean that products slide down easier than they detach. Designing a vertical fastening? Note that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the element will slip down under a much lighter weight. Using a rubber coating can significantly raise the stability.

12 mm	100%	4.43 kg / 9.77 LBS 4430.0 g / 43.5 N

A thin sheet is not enough to take in the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a thin surface, the flux will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this magnet's power, you need a suitably thick element of steel. The saturation phenomenon causes that on thin elements (e.g., car bodies), the product works worse. We advise picking the steel dimension according to the table below.

Table 5: Thermal resistance (stability) - thermal limit

Ordinary NdFeB products irreversibly lose strength above the temperature limit. Watch out for overheating – excessive heat can permanently demagnetize this product. As the temperature rises, the magnet's power momentarily decreases. Avoid using this magnet close to heaters exceeding its safe range. Ignoring the limit will lead to destruction of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) may lose charge permanently at lower temperatures than taller cylinders. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums interact from a wider radius than a magnet and steel setup. The connection of two magnets creates a more powerful interaction and a wider radius of performance. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when connecting a pair of magnets, the pinch force is huge. The levitation is slightly lower than the attraction, but still impressive.
*Flux density for N-N configuration reaches ~0 Gs at the midpoint between the magnets (due to field cancellation).
Note: Results apply to sliding force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field is a real danger to electronic devices and pacemakers. These magnets generate a field that destroys function of digital equipment. Be aware: the invisible magnetic field passes through tissues and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - warning
MW 16x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	27.98 km/h (7.77 m/s)	0.18 J

50 mm	61.12 km/h (16.98 m/s)	0.87 J
100 mm	86.44 km/h (24.01 m/s)	1.74 J

NdFeB products are delicate – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or dangerous crushing to fingers. Always hold the magnet during mounting so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the magnet. Use safety goggles when playing with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds just ~20% of its perpendicular strength.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) severely weakens 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) = 0.35

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.

This product is an incredibly powerful rod magnet, composed of modern NdFeB material, which, with dimensions of Ø16x4 mm, guarantees maximum efficiency. This specific item boasts a tolerance of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 4.43 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 43.46 N with a weight of only 6.03 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

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., 16.1 mm) using epoxy glues. To ensure long-term durability in automation, 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 professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø16x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø16x4 mm, which, at a weight of 6.03 g, makes it an element with impressive magnetic energy density. The value of 43.46 N means that the magnet is capable of holding a weight many times exceeding its own mass of 6.03 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 4 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.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Pros

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

They do not lose strength, even after nearly ten years – the decrease in power is only ~1% (based on measurements),
Neodymium magnets are remarkably resistant to magnetic field loss caused by external field sources,
The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnetic induction on the working layer of the magnet is maximum,
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...
In view of the potential of precise forming and adaptation to custom projects, neodymium magnets can be manufactured in a variety of forms and dimensions, which expands the range of possible applications,
Universal use in modern industrial fields – they are utilized in HDD drives, drive modules, advanced medical instruments, as well as technologically advanced constructions.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

What to avoid - cons of neodymium magnets: tips and applications.

At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated shapes.
Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Maximum holding power of the magnet – what it depends on?

The specified lifting capacity refers to the peak performance, measured under laboratory conditions, namely:

on a base made of structural steel, perfectly concentrating the magnetic flux
whose thickness equals approx. 10 mm
with a surface cleaned and smooth
with zero gap (without coatings)
under axial force direction (90-degree angle)
in stable room temperature

What influences lifting capacity in practice

Please note that the application force may be lower depending on elements below, in order of importance:

Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Steel thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be lost to the other side.
Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.

H&S for magnets

Keep away from computers

Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Powerful field

Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.

Impact on smartphones

Remember: neodymium magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, device, and navigation systems.

Mechanical processing

Dust generated during machining of magnets is combustible. Do not drill into magnets unless you are an expert.

Allergy Warning

Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, prevent direct skin contact and select coated magnets.

No play value

Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Keep away from kids and pets.

Health Danger

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

Hand protection

Protect your hands. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!

Risk of cracking

Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Demagnetization risk

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
