Physical analysis of the product - report

The following data represent the direct effect of a engineering simulation. Values rely on algorithms for the material Nd₂Fe₁₄B. Actual conditions may differ from theoretical values. Please consider these data as a preliminary roadmap for designers.

Pulling power drops significantly with every subsequent millimeter of distance. Note that even a microscopic distance (e.g., contamination, varnish, dust) noticeably reduces the pull force. Magnets operate optimally in perfect adhesion; air break drastically cuts the force. See how flashily the load capacity plummet, when the magnet does not touch flatly to the steel surface. When designing the assembly, avoid redundant distances.

The following data shows the approximate holding capacity needed to start the downward movement of the magnet down against a upright steel wall (considering standard friction). The holding force is relative to the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 15x3x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.57 kg / 1.26 lbs 570.0 g / 5.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.84 lbs 380.0 g / 3.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.42 lbs 190.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.95 kg / 2.09 lbs 950.0 g / 9.3 N

When placing a magnet on a vertical wall (e.g., a car body), it you can count on just approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip influence the fact that holders move down easier than they pop off the substrate. Designing a hanger? Remember that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slide down under a noticeably lighter load. Application of an anti-slip coating can significantly raise the stability.

12 mm	100%	1.90 kg / 4.19 lbs 1900.0 g / 18.6 N

A too thin steel is unable to take in the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a thin surface, the flux will penetrate right through and the holding will be smaller. To utilize the maximum of this magnet's potential, you require a sufficiently solid backing of metal. The saturation effect causes that on sheet metal structures (e.g., car bodies), the magnet shows lower pull force. We recommend selecting the steel cross-section based on the following data.

Table 5: Thermal stability (material behavior) - thermal limit
MPL 15x3x6 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

Classic neodymiums irreversibly lose power above the temperature limit. Protect against heat – excessive heat can permanently damage this product. As the temperature rises, the neodymium's power briefly lowers. Refrain from using this magnet in hot environments higher than its operating temperature limit. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) are more susceptible to demagnetization at lower temperatures compared to rod magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two magnetic products attract each other from a much further distance than a neodymium and metal setup. The setup of two magnets produces a massive flux and a larger range of action. Planning to create a powerful holder? Apply two magnets instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the pinch force is massive. The levitation is a bit weaker than the attraction, but still significant.
*Flux density between like poles reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Calculations apply to friction force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Hazards (implants) - precautionary measures
MPL 15x3x6 / N38

Object / Device	Limit (Gauss) / mT	Safe distance

Powerful magnet radiation is a serious hazard to electronic devices and pacemakers. These neodymiums produce a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - collision effects
MPL 15x3x6 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	30.88 km/h (8.58 m/s)	0.07 J
30 mm	53.44 km/h (14.84 m/s)	0.22 J
50 mm	68.99 km/h (19.16 m/s)	0.37 J
100 mm	97.57 km/h (27.10 m/s)	0.75 J

NdFeB products are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can trigger coating fragments or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear eye protection when handling 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. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds just approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly reduces the holding force.

3. Temperature resistance

*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) = 0.79

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.

Model MPL 15x3x6 / N38 features a flat shape and industrial pulling force, making it an ideal solution for building separators and machines. This rectangular block with a force of 18.68 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is shifting the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. Watch your fingers! Magnets with a force of 1.90 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 15x3x6 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 1.90 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 15x3x6 / N38, it is best to use two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 15x3x6 / N38 model is magnetized through the thickness (dimension 6 mm), which means that the N and S poles are located on its largest, flat surfaces. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. This is the most popular configuration for block magnets used in separators and holders.

The presented product is a neodymium magnet with precisely defined parameters: 15 mm (length), 3 mm (width), and 6 mm (thickness). It is a magnetic block with dimensions 15x3x6 mm and a self-weight of 2.03 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of rare earth magnets.

Strengths

Apart from their consistent holding force, neodymium magnets have these key benefits:

Their magnetic field is durable, and after approximately ten years it drops only by ~1% (theoretically),
They possess excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
By using a shiny layer of nickel, the element presents an nice look,
Magnets have exceptionally strong magnetic induction on the outer layer,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
Possibility of precise modeling and modifying to individual applications,
Versatile presence in innovative solutions – they are commonly used in data components, electromotive mechanisms, medical equipment, also modern systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing nuts and complicated shapes in magnets, we propose using a housing - magnetic mount.
Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting capacity of the magnet – what affects it?

Breakaway force was defined for optimal configuration, assuming:

on a block made of mild steel, effectively closing the magnetic flux
with a thickness no less than 10 mm
with a surface cleaned and smooth
with direct contact (no coatings)
for force applied at a right angle (in the magnet axis)
at temperature room level

Determinants of practical lifting force of a magnet

Effective lifting capacity is influenced by specific conditions, including (from priority):

Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
Surface finish – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was determined using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Warnings

Power loss in heat

Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.

Caution required

Be careful. Neodymium magnets attract from a distance and connect with massive power, often faster than you can move away.

Phone sensors

GPS units and mobile phones are highly sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.

Mechanical processing

Dust produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Fragile material

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.

Avoid contact if allergic

Certain individuals have a sensitization to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to dermatitis. We suggest wear protective gloves.

This is not a toy

Always store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are very dangerous.

Hand protection

Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Pacemakers

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

Data carriers

Device Safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).
