Technical modeling of the product - report

The following information represent the result of a physical simulation. Values are based on models for the material Nd₂Fe₁₄B. Real-world conditions may differ. Use these calculations as a supplementary guide for designers.

Magnetic force weakens significantly with every mm of gap. Remember that even a microscopic distance (e.g., contamination, varnish, rust) significantly weakens the grip. Magnetic products hold optimally during direct contact; air break weakens the force. Notice how flashily the parameters plummet, when the magnet does not touch directly to the metal substrate. When calculating the mounting, discard redundant distances.

This section indicates the theoretical force required to initiate the slippage of the magnet down against a vertical steel plate (considering standard friction coefficient). This value is a function of the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 8x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.55 kg / 1.22 LBS 552.0 g / 5.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.37 kg / 0.81 LBS 368.0 g / 3.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.18 kg / 0.41 LBS 184.0 g / 1.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.92 kg / 2.03 LBS 920.0 g / 9.0 N

When placing a element on a vertical wall (e.g., a car body), it will maintain barely approx. 1/5 of its nominal power. Gravity as well as a low friction coefficient cause that products slip easier than they pop off the substrate. Designing a vertical fastening? Remember that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the magnet will give way down under a much lighter cargo. Using a rubber layer can drastically increase the grip.

A thin metal plate is incapable of absorb the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To achieve full efficiency of this magnet's power, you need a suitably thick backing of metal. The saturation effect means that on delicate walls (e.g., car bodies), the product works worse. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products irreversibly lose strength after exceeding the maximum temperature. Avoid high temperatures – heat can permanently demagnetize this magnet. With increasing heat, the magnet's force temporarily lowers. Avoid using this product near heat sources higher than its operating temperature limit. Ignoring the limit will cause irreversible degradation of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) may lose charge permanently at lower temperatures than long magnets. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and steel setup. Such a system of two magnets produces a massive flux and a larger range of operation. Want to build a solid fastener? Use a pair of magnets instead of one magnet and a steel. Remember that when connecting a pair of magnets, the collision energy is massive. The repulsion force is a bit weaker than the attraction, but still impressive.
*Flux density in repulsion mode drops to ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Figures show sliding force of two same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a large risk to electronic devices and pacemakers. These magnets produce a field that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and plastic. Special caution must be taken by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely turns into a projectile. Kinetic force can trigger coating fragments or injury to fingers. Always hold the magnet 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. Wear eye protection when working with large magnets.

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Note: On a vertical surface, the magnet retains only ~20% of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) significantly weakens 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) = 1.00

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 presented product is an exceptionally strong cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø8x10 mm, guarantees the highest energy density. The MW 8x10 / N38 model is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 1.84 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 18.00 N with a weight of only 3.77 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using epoxy glues. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are strong enough for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø8x10), 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 8 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 1.84 kg (force ~18.00 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, 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 8 mm. Such an arrangement is standard 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 through the diameter if your project requires it.

Advantages and disadvantages of neodymium magnets.

Benefits

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They do not lose strength, even during approximately ten years – the reduction in strength is only ~1% (based on measurements),
They are noted for resistance to demagnetization induced by external disturbances,
By using a lustrous layer of silver, the element presents an modern look,
The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
Thanks to versatility in constructing and the capacity to adapt to client solutions,
Wide application in electronics industry – they are used in hard drives, electric drive systems, precision medical tools, and other advanced devices.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Weaknesses

Characteristics of disadvantages of neodymium magnets: application proposals

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing threads and complicated shapes in magnets, we recommend using cover - magnetic mount.
Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

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

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

using a base made of mild steel, serving as a ideal flux conductor
with a thickness no less than 10 mm
characterized by even structure
without any air gap between the magnet and steel
for force acting at a right angle (in the magnet axis)
at conditions approx. 20°C

What influences lifting capacity in practice

Please note that the magnet holding will differ depending on elements below, starting with the most relevant:

Gap between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.

Safety rules for work with NdFeB magnets

Allergic reactions

Some people suffer from a contact allergy to nickel, which is the standard coating for NdFeB magnets. Prolonged contact may cause a rash. We strongly advise wear protective gloves.

Safe distance

Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.

Impact on smartphones

Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your phone, tablet, and GPS.

Combustion hazard

Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.

Medical implants

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.

Adults only

NdFeB magnets are not suitable for play. Eating a few magnets can lead to them attracting across intestines, which poses a critical condition and requires immediate surgery.

Permanent damage

Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Protective goggles

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.

Crushing risk

Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!

Caution required

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

Warning! More info about hazards in the article: Safety of working with magnets.
