Engineering modeling of the magnet - data

The following data represent the outcome of a physical simulation. Values were calculated on models for the class Nd₂Fe₁₄B. Actual parameters might slightly differ from theoretical values. Treat these data as a reference point for designers.

Table 1: Static force (pull vs distance) - power drop
MPL 25x10x3 / N38

Distance (mm)	Induction (Gauss) / mT	Pull Force (kg/lbs/g/N)	Risk Status
0 mm	2306 Gs 230.6 mT	4.14 kg / 9.13 lbs 4140.0 g / 40.6 N	strong
1 mm	2050 Gs 205.0 mT	3.27 kg / 7.21 lbs 3272.4 g / 32.1 N	strong
2 mm	1752 Gs 175.2 mT	2.39 kg / 5.27 lbs 2388.9 g / 23.4 N	strong

10 mm	416 Gs 41.6 mT	0.13 kg / 0.30 lbs 134.4 g / 1.3 N	weak grip
15 mm	200 Gs 20.0 mT	0.03 kg / 0.07 lbs 31.0 g / 0.3 N	weak grip
20 mm	108 Gs 10.8 mT	0.01 kg / 0.02 lbs 9.0 g / 0.1 N	weak grip
30 mm	40 Gs 4.0 mT	0.00 kg / 0.00 lbs 1.3 g / 0.0 N	weak grip
50 mm	10 Gs 1.0 mT	0.00 kg / 0.00 lbs 0.1 g / 0.0 N	weak grip

Grip strength decreases significantly per each millimeter of gap. Remember that even a microscopic distance (e.g., dirt, varnish, veneer) significantly diminishes the holding power. Magnetic products operate most effectively in perfect adhesion; distance nullifies the power. Observe how flashily the parameters plummet, when the magnet does not adhere tightly to the metal substrate. When calculating the assembly, eliminate additional spacers.

Table 2: Sliding capacity (wall)
MPL 25x10x3 / N38

Distance (mm)	Friction coefficient	Pull Force (kg/lbs/g/N)
0 mm	Stal (~0.2)	0.83 kg / 1.83 lbs 828.0 g / 8.1 N
1 mm	Stal (~0.2)	0.65 kg / 1.44 lbs 654.0 g / 6.4 N
2 mm	Stal (~0.2)	0.48 kg / 1.05 lbs 478.0 g / 4.7 N
3 mm	Stal (~0.2)	0.33 kg / 0.74 lbs 334.0 g / 3.3 N
5 mm	Stal (~0.2)	0.16 kg / 0.34 lbs 156.0 g / 1.5 N
10 mm	Stal (~0.2)	0.03 kg / 0.06 lbs 26.0 g / 0.3 N
15 mm	Stal (~0.2)	0.01 kg / 0.01 lbs 6.0 g / 0.1 N
20 mm	Stal (~0.2)	0.00 kg / 0.00 lbs 2.0 g / 0.0 N
30 mm	Stal (~0.2)	0.00 kg / 0.00 lbs 0.0 g / 0.0 N
50 mm	Stal (~0.2)	0.00 kg / 0.00 lbs 0.0 g / 0.0 N

This section indicates the approximate holding capacity sufficient to initiate the sliding of the magnet down against a upright steel plate (assuming standard friction). This parameter depends on the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 25x10x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.24 kg / 2.74 lbs 1242.0 g / 12.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.83 kg / 1.83 lbs 828.0 g / 8.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.41 kg / 0.91 lbs 414.0 g / 4.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.07 kg / 4.56 lbs 2070.0 g / 20.3 N

When placing a magnet on a upright plane (e.g., a car body), it will maintain just about 1/5 of its maximum pull force. Gravitational force as well as a low friction coefficient cause that magnets slide down easier than they pull off. Planning a vertical fastening? Remember that the shear force is much weaker than the maximum static pull force. On a slippery surface, the magnet will slip down under a noticeably lighter load. Utilizing a rubberized pad can significantly improve the result.

Table 4: Material efficiency (saturation) - power losses
MPL 25x10x3 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.41 kg / 0.91 lbs 414.0 g / 4.1 N
1 mm	25%	1.04 kg / 2.28 lbs 1035.0 g / 10.2 N
2 mm	50%	2.07 kg / 4.56 lbs 2070.0 g / 20.3 N
3 mm	75%	3.10 kg / 6.85 lbs 3105.0 g / 30.5 N
5 mm	100%	4.14 kg / 9.13 lbs 4140.0 g / 40.6 N
10 mm	100%	4.14 kg / 9.13 lbs 4140.0 g / 40.6 N
11 mm	100%	4.14 kg / 9.13 lbs 4140.0 g / 40.6 N
12 mm	100%	4.14 kg / 9.13 lbs 4140.0 g / 40.6 N

A thin sheet is incapable of focus the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's power, you require a sufficiently solid element of metal. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the holder holds weaker. We advise picking the steel thickness according to the table below.

Table 5: Working in heat (stability) - thermal limit
MPL 25x10x3 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	4.14 kg / 9.13 lbs 4140.0 g / 40.6 N	OK
40 °C	-2.2%	4.05 kg / 8.93 lbs 4048.9 g / 39.7 N	OK
60 °C	-4.4%	3.96 kg / 8.73 lbs 3957.8 g / 38.8 N
80 °C	-6.6%	3.87 kg / 8.52 lbs 3866.8 g / 37.9 N
100 °C	-28.8%	2.95 kg / 6.50 lbs 2947.7 g / 28.9 N

Classic neodymiums change their properties parameters above the temperature limit. Avoid high temperatures – high temperature can permanently destroy this product. With increasing heat, the magnet's capacity briefly decreases. Avoid using this product in hot environments exceeding its operating temperature limit. Exceeding the critical threshold will cause destruction of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures than long magnets. Red status in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and steel setup. Such a system of magnet-to-magnet generates a stronger field and a larger range of action. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when bringing together two magnets, the impact force is extreme. The levitation is slightly lower than the connection force, but still impressive.
*Flux density between like poles drops to ~0 Gs in the exact middle of the gap (due to field cancellation).
Attention: Estimates demonstrate shear force of a pair of same neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to electronic devices as well as medical implants. These NdFeB products generate a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and housings. Exceptional care must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - warning
MPL 25x10x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	27.90 km/h (7.75 m/s)	0.17 J
30 mm	47.38 km/h (13.16 m/s)	0.49 J

Neodymium magnets are prone to chipping – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or dangerous crushing to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Wear safety glasses when handling with large magnets.

Water (riverbed)	4.74 kg (+0.60 kg buoyancy gain)	+14.5%

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Wall mount (shear)

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

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) drastically reduces the holding force.

3. Thermal stability

*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) = 0.25

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.

This product is an extremely strong plate magnet made of NdFeB material, which, with dimensions of 25x10x3 mm and a weight of 5.63 g, guarantees premium class connection. As a magnetic bar with high power (approx. 4.14 kg), this product is available immediately from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 25x10x3 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 25x10x3 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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 25x10x3 / N38 model is magnetized through the thickness (dimension 3 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. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 25 mm (length), 10 mm (width), and 3 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 4.14 kg (force ~40.56 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Benefits

Besides their stability, neodymium magnets are valued for these benefits:

They have stable power, and over more than ten years their performance decreases symbolically – ~1% (in testing),
Neodymium magnets are characterized by extremely resistant to demagnetization caused by external interference,
In other words, due to the glossy surface of silver, the element gains visual value,
Magnetic induction on the working layer of the magnet remains maximum,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
Thanks to the potential of accurate forming and customization to unique needs, neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies use scope,
Significant place in modern industrial fields – they are commonly used in computer drives, drive modules, advanced medical instruments, as well as multitasking production systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 advise using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complex shapes.
Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small elements of these products can be problematic in diagnostics medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

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

The declared magnet strength represents the maximum value, measured under ideal test conditions, meaning:

using a plate made of high-permeability steel, serving as a ideal flux conductor
possessing a massiveness of min. 10 mm to avoid saturation
with a plane free of scratches
under conditions of no distance (metal-to-metal)
during detachment in a direction vertical to the plane
at standard ambient temperature

Practical lifting capacity: influencing factors

In practice, the real power depends on a number of factors, ranked from the most important:

Gap (betwixt the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
Steel type – low-carbon steel attracts best. Higher carbon content decrease magnetic properties and lifting capacity.
Plate texture – ground elements ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the load capacity.

Safety rules for work with NdFeB magnets

Skin irritation risks

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.

Hand protection

Big blocks can smash fingers in a fraction of a second. Never place your hand between two strong magnets.

Machining danger

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

Magnet fragility

Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Keep away from computers

Intense magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Health Danger

For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.

GPS Danger

GPS units and mobile phones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.

Respect the power

Be careful. Neodymium magnets attract from a long distance and connect with huge force, often quicker than you can react.

No play value

Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Keep out of reach of children and animals.

Heat sensitivity

Control the heat. Exposing the magnet to high heat will permanently weaken its properties and strength.

Attention! Learn more about risks in the article: Magnet Safety Guide.
