Magnetic force decreases sharply with every subsequent millimeter of distance. Remember that even a microscopic distance (e.g., dirt, paint, rust) strongly reduces the pull force. Neodymiums hold most effectively at the point of direct contact; gap kills the power. Analyze how flashily the pull force fall, when the product does not touch directly to the metal substrate. When planning the mounting, eliminate redundant distances.

The following data indicates the approximate force sufficient to cause the shifting of the magnet downwards on a vertical metal surface (assuming typical friction coefficient). This value depends on the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MPL 40x10x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.79 kg / 2793.0 g 27.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.86 kg / 1862.0 g 18.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.93 kg / 931.0 g 9.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.66 kg / 4655.0 g 45.7 N

When placing a element on a vertical surface (e.g., a fridge), it you can count on barely about 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip influence the fact that magnets slip faster than they detach. Want to create a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the element will slip down under a much lighter weight. Application of an anti-slip layer can drastically raise the stability.

Table 4: Material efficiency (saturation) - power losses
MPL 40x10x4 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.93 kg / 931.0 g 9.1 N
1 mm	25%	2.33 kg / 2327.5 g 22.8 N
2 mm	50%	4.66 kg / 4655.0 g 45.7 N
5 mm	100%	9.31 kg / 9310.0 g 91.3 N
10 mm	100%	9.31 kg / 9310.0 g 91.3 N

A thin metal plate is not enough to conduct the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To utilize full efficiency of this magnet's power, you need a suitably thick backing of metal. The saturation phenomenon means that on sheet metal structures (e.g., car bodies), the product holds weaker. We advise picking the steel cross-section from these parameters.

Table 5: Thermal stability (stability) - resistance threshold
MPL 40x10x4 / N38

Ambient temp. (°C)	Power loss	Remaining pull	Status
20 °C	0.0%	9.31 kg / 9310.0 g 91.3 N	OK
40 °C	-2.2%	9.11 kg / 9105.2 g 89.3 N	OK
60 °C	-4.4%	8.90 kg / 8900.4 g 87.3 N
80 °C	-6.6%	8.70 kg / 8695.5 g 85.3 N
100 °C	-28.8%	6.63 kg / 6628.7 g 65.0 N

Ordinary NdFeB products lose strength past the thermal threshold. Avoid high temperatures – high temperature can irreversibly damage this product. With increasing heat, the neodymium's capacity momentarily drops. Do not use this magnet in hot environments higher than its safe range. Ignoring the limit will lead to destruction of magnetism.

*Important note: Thermal stability is determined by both grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures compared to rod magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a much further distance than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the impact force is huge. The levitation is a bit weaker than the connection force, but still significant.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).

Table 7: Hazards (electronics) - warnings

Powerful magnet radiation poses a large risk to electronics and pacemakers. These magnets generate a field that destroys function of digital equipment. Notice: the invisible magnetic field penetrates the body and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Collisions (cracking risk) - collision effects
MPL 40x10x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	28.72 km/h (7.98 m/s)	0.38 J
30 mm	48.67 km/h (13.52 m/s)	1.10 J
50 mm	62.82 km/h (17.45 m/s)	1.83 J
100 mm	88.83 km/h (24.68 m/s)	3.65 J

NdFeB products are prone to chipping – a collision with steel can result in shattering. Pay attention to connection velocity – a magnet released freely turns into a projectile. Impact energy can trigger coating fragments or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear safety glasses when working with powerful specimens.

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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Warning: On a vertical surface, the magnet retains only approx. 20-30% of its nominal pull.

2. Plate thickness effect

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.26

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 a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 40x10x4 mm and a weight of 12 g, guarantees premium class connection. As a magnetic bar with high power (approx. 9.31 kg), this product is available off-the-shelf from our warehouse in Poland. 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. To separate the MPL 40x10x4 / 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 40x10x4 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 9.31 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.

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 40x10x4 / N38 model is magnetized axially (dimension 4 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: 40 mm (length), 10 mm (width), and 4 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 9.31 kg (force ~91.33 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of neodymium magnets.

Benefits

Apart from their superior power, neodymium magnets have these key benefits:

They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (in testing),
Neodymium magnets are extremely resistant to magnetic field loss caused by external interference,
A magnet with a metallic gold surface has better aesthetics,
They show high magnetic induction at the operating surface, which increases their power,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to freedom in constructing and the capacity to customize to unusual requirements,
Significant place in electronics industry – they are used in computer drives, motor assemblies, medical devices, as well as multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Weaknesses

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
Limited possibility of making nuts in the magnet and complicated forms - recommended is a housing - mounting mechanism.
Health risk to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small components of these devices can be problematic in diagnostics medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Highest magnetic holding force – what affects it?

Breakaway force is the result of a measurement for optimal configuration, taking into account:

using a sheet made of low-carbon steel, serving as a ideal flux conductor
with a cross-section minimum 10 mm
with a surface free of scratches
with direct contact (no impurities)
for force applied at a right angle (in the magnet axis)
at standard ambient temperature

Impact of factors on magnetic holding capacity in practice

Real force is influenced by working environment parameters, mainly (from priority):

Gap (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or dirt).
Direction of force – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
Plate thickness – too thin sheet does not close the flux, causing part of the power to be wasted to the other side.
Chemical composition of the base – mild steel gives the best results. Higher carbon content decrease magnetic properties and lifting capacity.
Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Warnings

Dust is flammable

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

Electronic hazard

Device Safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Handling rules

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

Do not give to children

Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Keep away from children and animals.

Crushing risk

Mind your fingers. Two large magnets will snap together immediately with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Phone sensors

A powerful magnetic field interferes with the operation of magnetometers in phones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.

Protective goggles

Neodymium magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.

Heat warning

Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.

Health Danger

Warning for patients: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.

Skin irritation risks

Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands and select versions in plastic housing.

Warning! Learn more about hazards in the article: Magnet Safety Guide.
