Technical modeling of the magnet - technical parameters

The following data represent the result of a mathematical calculation. Results were calculated on models for the class Nd₂Fe₁₄B. Operational performance may differ. Use these calculations as a reference point when designing systems.

Table 1: Static pull force (pull vs distance) - interaction chart
MP 20x10x5 / N38

Distance (mm)	Induction (Gauss) / mT	Pull Force (kg/lbs/g/N)	Risk Status
0 mm	5917 Gs 591.7 mT	5.20 kg / 11.46 pounds 5200.0 g / 51.0 N	medium risk

15 mm	907 Gs 90.7 mT	0.12 kg / 0.27 pounds 122.3 g / 1.2 N	weak grip

50 mm	75 Gs 7.5 mT	0.00 kg / 0.00 pounds 0.8 g / 0.0 N	weak grip

Pulling power drops significantly with every subsequent millimeter of distance. Note that even a very thin break (e.g., contamination, paint, veneer) significantly weakens the grip. Magnets hold strongest during direct contact; distance weakens the power. Analyze how flashily the load capacity plummet, when the magnet does not adhere flatly to the metal substrate. When calculating the arrangement, avoid additional spacers.

The following data presents the approximate weight limit needed to start the downward movement of the magnet vertically against a vertical steel plate (considering standard friction). The holding force is a function of the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MP 20x10x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.56 kg / 3.44 pounds 1560.0 g / 15.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.04 kg / 2.29 pounds 1040.0 g / 10.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.52 kg / 1.15 pounds 520.0 g / 5.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.60 kg / 5.73 pounds 2600.0 g / 25.5 N

When placing a magnet on a upright plane (e.g., a board), it will only hold only about 20%-30% of its maximum pull force. Gravitational force as well as a low friction coefficient influence the fact that products move down faster than they pop off the substrate. Designing a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will give way down under a much lighter weight. Using a rubber coating can significantly raise the stability.

Table 4: Steel thickness (saturation) - sheet metal selection
MP 20x10x5 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.52 kg / 1.15 pounds 520.0 g / 5.1 N
1 mm	25%	1.30 kg / 2.87 pounds 1300.0 g / 12.8 N
2 mm	50%	2.60 kg / 5.73 pounds 2600.0 g / 25.5 N
3 mm	75%	3.90 kg / 8.60 pounds 3900.0 g / 38.3 N
5 mm	100%	5.20 kg / 11.46 pounds 5200.0 g / 51.0 N
10 mm	100%	5.20 kg / 11.46 pounds 5200.0 g / 51.0 N
11 mm	100%	5.20 kg / 11.46 pounds 5200.0 g / 51.0 N
12 mm	100%	5.20 kg / 11.46 pounds 5200.0 g / 51.0 N

A too thin steel is unable to take in the entire magnetic field, which weakens actual performance of the magnet. Should you mount a strong magnet to a too thin substrate, the magnetism will pass right through and the holding will be smaller. To achieve 100% of this magnet's potential, you require a sufficiently solid piece of steel. The material oversaturation means that on thin elements (e.g., car bodies), the product holds weaker. We suggest choosing the steel thickness based on the following data.

Table 5: Thermal resistance (material behavior) - power drop
MP 20x10x5 / N38

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

40 °C	-2.2%	5.09 kg / 11.21 pounds 5085.6 g / 49.9 N	OK
60 °C	-4.4%	4.97 kg / 10.96 pounds 4971.2 g / 48.8 N	OK

100 °C	-28.8%	3.70 kg / 8.16 pounds 3702.4 g / 36.3 N

Ordinary NdFeB products lose power after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently demagnetize this magnet. As the temperature rises, the magnet's capacity briefly lowers. Do not use this magnet near heat sources exceeding its working range. Too high temperature will lead to irreversible degradation of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently under lower heat stress compared to rod magnets. The danger warning in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and steel setup. The setup of two magnets produces a massive flux and a larger range of performance. Designing a strong closure? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when bringing together two magnets, the pinch force is extreme. The levitation is a bit weaker than the connection force, but still significant.
*The magnetic induction between like poles is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Calculations show shear force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a large risk to electronics and medical implants. These NdFeB products produce a field that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field acts through matter and glass. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - warning
MP 20x10x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	25.62 km/h (7.12 m/s)	0.22 J
30 mm	42.41 km/h (11.78 m/s)	0.61 J
50 mm	54.70 km/h (15.19 m/s)	1.02 J
100 mm	77.35 km/h (21.49 m/s)	2.04 J

Magnetic elements are very brittle – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely turns into a projectile. Kinetic force can cause material chips or painful pinches to skin. Be sure to control the product during mounting so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear safety glasses when playing with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

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

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) significantly limits the holding force.

3. Heat tolerance

*For standard magnets, 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) = 1.13

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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. This product with a force of 5.20 kg works great as a door latch, speaker holder, or mounting element in devices.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. One turn too many can destroy the magnet, so do it slowly. The flat screw head should evenly press the magnet. Remember: cracking during assembly results from material properties, not a product defect.

These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but is not sufficient for rain. In the place of the mounting hole, the coating is thinner and easily scratched when tightening the screw, which will become a corrosion focus. This product is dedicated for inside building use. For outdoor applications, we recommend choosing magnets in hermetic housing or additional protection with varnish.

The inner hole diameter determines the maximum size of the mounting element. If the magnet does not have a chamfer (cone), we recommend using a screw with a flat or cylindrical head, or possibly using a washer. Aesthetic mounting requires selecting the appropriate head size.

It is a magnetic ring with a diameter of 20 mm and thickness 5 mm. The key parameter here is the holding force amounting to approximately 5.20 kg (force ~50.97 N). The mounting hole diameter is precisely 10 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. In the case of connecting two rings, make sure one is turned the right way. We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Advantages and disadvantages of rare earth magnets.

Pros

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (in testing),
They feature excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
By using a shiny coating of nickel, the element has an proper look,
Neodymium magnets achieve maximum magnetic induction on a small surface, which allows for strong attraction,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Due to the ability of flexible shaping and adaptation to custom requirements, magnetic components can be produced in a wide range of forms and dimensions, which increases their versatility,
Significant place in electronics industry – they are utilized in data components, electromotive mechanisms, medical devices, as well as complex engineering applications.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of neodymium magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Due to limitations in realizing threads and complicated forms in magnets, we recommend using a housing - magnetic holder.
Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these products can complicate diagnosis medical when they are in the body.
Due to complex production process, their price is higher than average,

Holding force characteristics

Best holding force of the magnet in ideal parameters – what affects it?

The load parameter shown represents the limit force, recorded under ideal test conditions, namely:

on a plate made of mild steel, optimally conducting the magnetic field
possessing a thickness of minimum 10 mm to avoid saturation
with an polished contact surface
with zero gap (no impurities)
during detachment in a direction vertical to the plane
at standard ambient temperature

Lifting capacity in real conditions – factors

In practice, the actual holding force results from a number of factors, listed from crucial:

Clearance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was measured by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

H&S for magnets

Operating temperature

Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and pulling force.

Precision electronics

A strong magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.

Immense force

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

Sensitization to coating

Medical facts indicate that nickel (the usual finish) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands and choose encased magnets.

Fire warning

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Adults only

Always store magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are life-threatening.

Health Danger

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

Hand protection

Pinching hazard: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.

Fragile material

Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Electronic devices

Device Safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
