Engineering modeling of the magnet - report

The following information constitute the result of a mathematical calculation. Results were calculated on algorithms for the class Nd₂Fe₁₄B. Operational conditions might slightly deviate from the simulation results. Please consider these calculations as a supplementary guide during assembly planning.

Grip strength drops drastically with every mm of spacing. Remember that even a microscopic distance (e.g., dirt, paint, veneer) significantly reduces the pull force. Magnets hold optimally at the point of direct contact; distance nullifies the force. Notice how rapidly the pull force fall, when the product does not adhere flatly to the steel surface. When designing the assembly, discard unnecessary gaps.

The following data indicates the theoretical weight limit necessary to cause the downward movement of the magnet downwards along a upright steel plate (assuming typical friction). The holding force depends on the air gap between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 8x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.61 kg / 1.34 LBS 609.0 g / 6.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.41 kg / 0.90 LBS 406.0 g / 4.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.20 kg / 0.45 LBS 203.0 g / 2.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.02 kg / 2.24 LBS 1015.0 g / 10.0 N

When placing a magnet on a upright plane (e.g., a fridge), it will maintain barely approx. 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip mean that magnets slip faster than they pull off. Designing a vertical fastening? Note that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will slide down under a much lighter load. Utilizing a rubberized coating can significantly improve the result.

A too thin steel is not enough to take in the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To achieve 100% of this magnet's potential, you need a suitably thick element of steel. The saturation phenomenon causes that on thin elements (e.g., appliance housings), the magnet shows lower pull force. We advise picking the steel thickness based on the following data.

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently destroy this product. As the temperature rises, the magnet's force briefly lowers. Refrain from using this magnet close to heaters higher than its safe range. Exceeding the critical threshold will result in permanent loss of magnetism.

*Important note: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) may lose charge permanently under lower heat stress than taller cylinders. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnets attract each other from a much further distance than a magnet and steel combination. The connection of two magnets generates a stronger field and a further horizon of action. Want to build a strong closure? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the impact force is huge. The repulsion force is marginally weaker than the connection force, but still significant.
*Field value in repulsion mode drops to ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Attention: Estimates demonstrate shear force of a pair of same neodymium magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field poses a serious hazard to IT equipment as well as medical implants. These NdFeB products generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and housings. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - collision effects
MW 8x8 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	26.19 km/h (7.28 m/s)	0.08 J
30 mm	45.29 km/h (12.58 m/s)	0.24 J
50 mm	58.47 km/h (16.24 m/s)	0.40 J
100 mm	82.68 km/h (22.97 m/s)	0.80 J

NdFeB products are very brittle – a strong collision with metal risks their cracking. Control the attraction moment – a neodymium left loose speeds with massive force. Kinetic force can destroy the magnet or injury to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear safety glasses when handling with large magnets.

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

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

1. Vertical hold

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

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

3. Temperature resistance

*For N38 material, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.89

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.

The offered product is a very strong rod magnet, composed of durable NdFeB material, which, with dimensions of Ø8x8 mm, guarantees optimal power. The MW 8x8 / N38 component features an accuracy of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 2.03 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 19.92 N with a weight of only 3.02 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel 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 the strongest magnets in the same volume (Ø8x8), 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 Ø8x8 mm, which, at a weight of 3.02 g, makes it an element with impressive magnetic energy density. The value of 19.92 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.02 g. 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 8 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 diametrically if your project requires it.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

Besides their immense field intensity, neodymium magnets offer the following advantages:

Their strength remains stable, and after approximately 10 years it drops only by ~1% (according to research),
Neodymium magnets are exceptionally resistant to magnetic field loss caused by external magnetic fields,
In other words, due to the reflective finish of nickel, the element gains visual value,
They show high magnetic induction at the operating surface, which increases their power,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
Thanks to versatility in shaping and the capacity to adapt to individual projects,
Versatile presence in electronics industry – they find application in mass storage devices, electric drive systems, medical equipment, and multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions

Cons

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
We recommend casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these devices are able to be problematic in diagnostics medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum magnetic pulling force – what affects it?

The declared magnet strength concerns the maximum value, obtained under ideal test conditions, namely:

with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
with a cross-section minimum 10 mm
with an polished touching surface
under conditions of no distance (surface-to-surface)
under vertical application of breakaway force (90-degree angle)
at room temperature

Lifting capacity in practice – influencing factors

Please note that the magnet holding will differ subject to the following factors, in order of importance:

Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Steel type – mild steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
Surface quality – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.

H&S for magnets

Electronic devices

Data protection: Strong magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).

Product not for children

Neodymium magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which poses a critical condition and necessitates immediate surgery.

Beware of splinters

Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.

Physical harm

Large magnets can crush fingers instantly. Do not place your hand between two attracting surfaces.

Combustion hazard

Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.

Powerful field

Exercise caution. Rare earth magnets act from a long distance and snap with massive power, often faster than you can react.

GPS Danger

An intense magnetic field disrupts the operation of compasses in phones and GPS navigation. Maintain magnets near a smartphone to avoid damaging the sensors.

Medical interference

Warning for patients: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Heat warning

Monitor thermal conditions. Heating the magnet to high heat will ruin its properties and strength.

Skin irritation risks

A percentage of the population have a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Extended handling can result in skin redness. We recommend use protective gloves.
