Pulling power decreases sharply with every subsequent millimeter of distance. Note that every additional insulation layer (e.g., contamination, varnish, rust) strongly diminishes the holding power. Neodymiums hold strongest during direct contact; distance kills the power. See how flashily the load capacity plummet, when the product does not touch tightly to the steel surface. When designing the mounting, discard unnecessary gaps.

This section defines the approximate force required to start the shifting of the magnet vertically along a upright steel plate (considering standard friction coefficient). The holding force is a function of the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 40x15x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	4.26 kg / 9.40 lbs 4263.0 g / 41.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.84 kg / 6.27 lbs 2842.0 g / 27.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.42 kg / 3.13 lbs 1421.0 g / 13.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	7.11 kg / 15.66 lbs 7105.0 g / 69.7 N

When placing a element on a upright surface (e.g., a fridge), it will only hold only about 1/5 of its nominal power. Gravitational force and a low friction coefficient influence the fact that holders slip faster than they detach. Want to create a vertical fastening? Note that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a much lighter weight. Application of an anti-slip layer can effectively improve the result.

3 mm	38%	5.33 kg / 11.75 lbs 5328.8 g / 52.3 N
5 mm	63%	8.88 kg / 19.58 lbs 8881.3 g / 87.1 N

12 mm	100%	14.21 kg / 31.33 lbs 14210.0 g / 139.4 N

A thin sheet is not enough to conduct the full magnetic flux, which wastes potential of the magnet. If you install a neodymium to a weak sheet, the field will pass right through and the holding will be smaller. To squeeze full efficiency of this neodymium's power, you require a sufficiently solid element of steel. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the holder shows lower pull force. We advise picking the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose power after exceeding the maximum temperature. Avoid high temperatures – high temperature can irreversibly damage this magnet. As the temperature rises, the magnet's capacity temporarily lowers. Refrain from using this product near heat sources exceeding its working range. Exceeding the critical threshold will cause permanent loss of magnetism.

*Important note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) may lose charge permanently under lower heat stress than long magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and steel combination. The setup of two magnets creates a more powerful interaction and a further horizon of action. Designing a strong closure? Utilize two neodymiums instead of one magnet and a steel. Remember that when bringing together two magnets, the impact force is huge. The levitation is marginally weaker than the connection force, but still impressive.
*Flux density for N-N configuration is approximately ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Figures show sliding force of two identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to IT equipment as well as pacemakers. These neodymiums produce a flux that disrupts operation of digital equipment. Be aware: the unseen radiation penetrates the body and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - warning
MPL 40x15x6 / N38

Start from (mm)	Speed (km/h)	Energy (J)

100 mm	73.16 km/h (20.32 m/s)	5.58 J

Magnetic elements are prone to chipping – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely becomes dangerous. Striking energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when playing 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!

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

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

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) severely reduces the holding force.

3. Heat tolerance

*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) = 0.31

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 plate magnet made of NdFeB material, which, with dimensions of 40x15x6 mm and a weight of 27 g, guarantees premium class connection. This magnetic block with a force of 139.45 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.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 40x15x6 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 40x15x6 / 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. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

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. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 40x15x6 / 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.

This model is characterized by dimensions 40x15x6 mm, which, at a weight of 27 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 14.21 kg (force ~139.45 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of neodymium magnets.

Pros

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
They retain their magnetic properties even under external field action,
By applying a smooth coating of gold, the element acquires an elegant look,
Magnetic induction on the working part of the magnet is maximum,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
Due to the ability of accurate molding and customization to unique requirements, NdFeB magnets can be modeled in a broad palette of shapes and sizes, which amplifies use scope,
Key role in modern industrial fields – they are utilized in HDD drives, drive modules, advanced medical instruments, also industrial machines.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
NdFeB 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
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
We suggest cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these products can be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Highest magnetic holding force – what contributes to it?

Information about lifting capacity was determined for the most favorable conditions, assuming:

with the use of a sheet made of special test steel, ensuring maximum field concentration
with a cross-section of at least 10 mm
with a plane perfectly flat
without the slightest clearance between the magnet and steel
for force applied at a right angle (in the magnet axis)
at room temperature

Impact of factors on magnetic holding capacity in practice

In real-world applications, the actual holding force is determined by several key aspects, ranked from crucial:

Distance (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Load vector – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel grade – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.

Precautions when working with NdFeB magnets

Crushing force

Large magnets can crush fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.

Threat to electronics

Equipment safety: Strong magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).

Do not underestimate power

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Magnets are brittle

NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them breaking into shards.

Warning for heart patients

Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Dust explosion hazard

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

GPS and phone interference

An intense magnetic field negatively affects the functioning of compasses in phones and navigation systems. Do not bring magnets near a smartphone to prevent breaking the sensors.

Power loss in heat

Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.

Swallowing risk

Adult use only. Small elements can be swallowed, causing serious injuries. Keep away from kids and pets.

Metal Allergy

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands and opt for encased magnets.
