Technical analysis of the assembly - technical parameters

Presented values constitute the direct effect of a mathematical analysis. Results are based on models for the material Nd₂Fe₁₄B. Operational performance might slightly deviate from the simulation results. Treat these calculations as a preliminary roadmap for designers.

Pulling power drops sharply with every subsequent millimeter of gap. Keep in mind that even a very thin break (e.g., dirt, varnish, dust) significantly weakens the grip. Magnets operate strongest at the point of direct contact; distance nullifies the power. Notice how quickly the parameters fall, when the product does not adhere flatly to the metal substrate. When designing the arrangement, avoid redundant distances.

This section indicates the approximate holding capacity sufficient to cause the sliding of the magnet downwards along a vertical steel plate (considering standard friction). This parameter is relative to the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 4x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.12 kg / 0.27 LBS 123.0 g / 1.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.08 kg / 0.18 LBS 82.0 g / 0.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.09 LBS 41.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.21 kg / 0.45 LBS 205.0 g / 2.0 N

When hanging a element on a upright surface (e.g., a fridge), it will maintain just approx. 1/5 of its nominal power. Gravitational force and a low friction coefficient influence the fact that holders slide down easier than they pop off the substrate. Planning a hanger? Note that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slide down under a noticeably lighter cargo. Using a rubber pad can significantly improve the result.

A too thin steel cannot focus the full magnetic flux, which weakens actual performance of the magnet. If you mount a strong magnet to a weak sheet, the flux will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's potential, you require a sufficiently solid element of metal. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the product works worse. We suggest choosing the steel dimension based on the following data.

Ordinary NdFeB products irreversibly lose parameters above the temperature limit. Watch out for overheating – heat can permanently demagnetize this magnet. With every degree above norm, the magnet's force temporarily drops. Do not use this product close to ovens exceeding its operating temperature limit. Ignoring the limit will result in destruction of magnetism.

*Engineering note: Temperature resistance is determined by both grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently sooner compared to rod magnets. Red status in the table points to permanent field degradation for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and steel setup. The setup of magnet-to-magnet produces a massive flux and a larger range of performance. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the pinch force is extreme. The levitation is slightly lower than the connection force, but still large.
*Flux density in repulsion mode drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Important: Figures refer to friction force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field is a real danger to IT equipment and medical implants. These magnets generate a field that destroys function of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and housings. Special caution 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, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can cause material chips or injury to skin. Be sure to control the product during bringing near metal so it doesn't hit violently against the metal. A collision at high speed means shattering of the neodymium. Use safety goggles when working 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.

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

1. Sliding resistance

*Warning: On a vertical wall, the magnet retains merely approx. 20-30% of its max power.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) drastically limits the holding force.

3. Heat tolerance

*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) = 1.09

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.

The offered product is an exceptionally strong cylinder magnet, composed of durable NdFeB material, which, with dimensions of Ø4x6 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 0.41 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 4.06 N with a weight of only 0.57 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are strong enough for 90% of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø4x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 4 mm and height 6 mm. The key parameter here is the lifting capacity amounting to approximately 0.41 kg (force ~4.06 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 6 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized diametrically if your project requires it.

Pros and cons of Nd₂Fe₁₄B magnets.

Pros

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

They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
Neodymium magnets are distinguished by extremely resistant to magnetic field loss caused by external field sources,
In other words, due to the smooth surface of gold, the element becomes visually attractive,
The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Possibility of detailed forming as well as adapting to specific applications,
Key role in innovative solutions – they are used in data components, motor assemblies, medical equipment, as well as complex engineering applications.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

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.
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
Limited possibility of making nuts in the magnet and complex shapes - recommended is cover - mounting mechanism.
Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Detachment force of the magnet in optimal conditions – what affects it?

The declared magnet strength refers to the limit force, measured under ideal test conditions, specifically:

on a block made of structural steel, effectively closing the magnetic field
whose thickness equals approx. 10 mm
characterized by even structure
with total lack of distance (no impurities)
for force acting at a right angle (in the magnet axis)
in stable room temperature

Magnet lifting force in use – key factors

Holding efficiency is affected by working environment parameters, including (from priority):

Gap (betwixt the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or dirt).
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Base massiveness – too thin plate does not accept the full field, causing part of the flux to be escaped to the other side.
Material type – ideal substrate is pure iron steel. Stainless steels may attract less.
Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
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).

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Safety rules for work with neodymium magnets

Finger safety

Danger of trauma: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

This is not a toy

Absolutely store magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are tragic.

Medical implants

Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Data carriers

Data protection: Neodymium magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Impact on smartphones

GPS units and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.

Caution required

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

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop handling magnets and use protective gear.

Permanent damage

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Do not drill into magnets

Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Risk of cracking

NdFeB magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets will cause them breaking into small pieces.
