Pulling power decreases significantly per each millimeter of distance. Keep in mind that even the smallest gap (e.g., dirt, varnish, dust) strongly weakens the grip. Magnetic products work strongest at the point of direct contact; air break nullifies the power. Notice how quickly the pull force drop, when the product does not touch directly to the metal substrate. When calculating the assembly, discard redundant distances.

The following data indicates the theoretical holding capacity needed to start the slippage of the magnet downwards along a upright steel plate (assuming standard friction). The holding force depends on the air gap between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MPL 10x4x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.26 kg / 0.58 lbs 264.0 g / 2.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.18 kg / 0.39 lbs 176.0 g / 1.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.09 kg / 0.19 lbs 88.0 g / 0.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.44 kg / 0.97 lbs 440.0 g / 4.3 N

When placing a holder on a upright surface (e.g., a board), it will only hold barely approx. 1/5 of its maximum pull force. Gravity as well as a low friction coefficient cause that products move down easier than they pull off. Designing a wall mount? Remember that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the magnet will slip down under a significantly smaller cargo. Application of an anti-slip pad can drastically raise the stability.

12 mm	100%	0.88 kg / 1.94 lbs 880.0 g / 8.6 N

A too thin steel is unable to conduct the entire magnetic field, which weakens actual performance of the holder. If you mount a strong magnet to a thin surface, the flux will pass right through and the holding will be smaller. To squeeze full efficiency of this neodymium's power, you require a sufficiently solid backing of metal. The material oversaturation causes that on delicate walls (e.g., thin profiles), the holder shows lower pull force. We recommend selecting the steel cross-section from these parameters.

Ordinary NdFeB products change their properties strength past the thermal threshold. Protect against heat – excessive heat can irreversibly damage this magnet. As the temperature rises, the magnet's force momentarily lowers. Avoid using this product in hot environments exceeding its safe range. Too high temperature will result in permanent loss of magnetism.

*Technical advisory: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of operation. Want to build a powerful holder? Apply two magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the collision energy is extreme. The levitation is a bit weaker than the attraction, but still impressive.
*The magnetic induction between like poles is approximately ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Important: Estimates demonstrate sliding force of two identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a serious hazard to electronic devices and medical implants. These neodymiums generate a field that prevents correct functioning of digital equipment. Remember: the unseen radiation passes through tissues and housings. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can cause material chips or painful pinches to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the metal. A collision at high speed means shattering of the neodymium. Wear safety glasses when playing with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

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

2. Plate thickness effect

*Thin steel (e.g. computer case) severely limits 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) = 0.30

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.

Component MPL 10x4x1.5 / N38 features a low profile and professional pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 0.88 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.

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 10x4x1.5 / 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. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 0.88 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 10x4x1.5 / N38 model is magnetized axially (dimension 1.5 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (10x4 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 10x4x1.5 mm, which, at a weight of 0.45 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 10x4x1.5 mm and a self-weight of 0.45 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of neodymium magnets.

Pros

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

They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
They feature excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an aesthetic appearance,
Neodymium magnets deliver maximum magnetic induction on a small area, which increases force concentration,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Thanks to the option of flexible forming and adaptation to custom projects, NdFeB magnets can be modeled in a variety of geometric configurations, which makes them more universal,
Versatile presence in future technologies – they are utilized in magnetic memories, motor assemblies, advanced medical instruments, and industrial machines.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in compact constructions

Cons

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complicated forms in magnets, we propose using a housing - magnetic mount.
Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products can complicate diagnosis medical in case of swallowing.
Due to complex production process, their price exceeds standard values,

Lifting parameters

Maximum magnetic pulling force – what it depends on?

The load parameter shown concerns the peak performance, obtained under laboratory conditions, specifically:

with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
possessing a thickness of min. 10 mm to avoid saturation
characterized by smoothness
under conditions of ideal adhesion (metal-to-metal)
during pulling in a direction perpendicular to the plane
at ambient temperature approx. 20 degrees Celsius

Key elements affecting lifting force

During everyday use, the real power is determined by a number of factors, ranked from crucial:

Distance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Safe handling of neodymium magnets

Safe operation

Be careful. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can move away.

Safe distance

Very strong magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.

Phone sensors

Note: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and navigation systems.

Bodily injuries

Danger of trauma: The pulling power is so great that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.

Avoid contact if allergic

It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, refrain from direct skin contact and choose versions in plastic housing.

Flammability

Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Adults only

Absolutely store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are very dangerous.

Pacemakers

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

Permanent damage

Avoid heat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Risk of cracking

NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets will cause them shattering into shards.
