Grip strength drops drastically per each millimeter of spacing. Note that even a very thin break (e.g., dirt, varnish, veneer) strongly reduces the pull force. Magnetic products hold most effectively at the point of direct contact; gap drastically cuts the power. Notice how rapidly the pull force fall, when the product does not adhere directly to the metal substrate. When calculating the arrangement, eliminate unnecessary gaps.

The following data shows the approximate holding capacity needed to start the slippage of the magnet down along a vertical steel plate (assuming standard friction coefficient). This parameter is relative to the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 15x3x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.57 kg / 1.26 LBS 570.0 g / 5.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.84 LBS 380.0 g / 3.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.42 LBS 190.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.95 kg / 2.09 LBS 950.0 g / 9.3 N

When mounting a magnet on a upright wall (e.g., a car body), it you can count on just approx. 1/5 of its nominal power. Gravity and a weak degree of grip cause that holders slip faster than they detach. Designing a hanger? Remember that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will give way down under a much lighter weight. Utilizing a rubberized pad can significantly increase the grip.

Table 4: Steel thickness (saturation) - sheet metal selection
MPL 15x3x6 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.19 kg / 0.42 LBS 190.0 g / 1.9 N

11 mm	100%	1.90 kg / 4.19 LBS 1900.0 g / 18.6 N
12 mm	100%	1.90 kg / 4.19 LBS 1900.0 g / 18.6 N

A thin sheet is unable to take in the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a too thin substrate, the magnetism will pass right through and the holding will be smaller. To utilize full efficiency of this neodymium's potential, you need a suitably thick element of steel. The saturation effect causes that on thin elements (e.g., appliance housings), the holder shows lower pull force. We recommend selecting the steel thickness according to the table below.

Table 5: Thermal stability (material behavior) - thermal limit
MPL 15x3x6 / N38

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

100 °C	-28.8%	1.35 kg / 2.98 LBS 1352.8 g / 13.3 N

Ordinary NdFeB products change their properties parameters above the temperature limit. Avoid high temperatures – high temperature can permanently damage this magnet. With every degree above norm, the neodymium's force momentarily decreases. Do not use this product in hot environments higher than its working range. Too high temperature will lead to destruction of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) risk losing magnetic properties at lower temperatures than long magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet combination. Such a system of two magnets creates a more powerful interaction and a wider radius of action. Designing a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is slightly lower than the connection force, but still large.
*Flux density for N-N configuration reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Attention: Calculations refer to sliding force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field poses a real danger to electronics as well as pacemakers. These NdFeB products generate a flux that destroys function of digital equipment. Notice: the invisible magnetic field acts through matter and plastic. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Table 8: Dynamics (kinetic energy) - collision effects
MPL 15x3x6 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	30.88 km/h (8.58 m/s)	0.07 J
30 mm	53.44 km/h (14.84 m/s)	0.22 J
50 mm	68.99 km/h (19.16 m/s)	0.37 J
100 mm	97.57 km/h (27.10 m/s)	0.75 J

NdFeB products are delicate – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Impact energy can cause material chips or painful pinches to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Use safety goggles when working with large magnets.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

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

1. Vertical hold

*Caution: On a vertical surface, the magnet holds merely approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly weakens the holding force.

3. Heat tolerance

*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) = 0.79

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.

Model MPL 15x3x6 / N38 features a low profile and professional pulling force, making it an ideal solution for building separators and machines. This rectangular block with a force of 18.68 N is ready for shipment in 24h, allowing for rapid realization of your project. 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. Watch your fingers! Magnets with a force of 1.90 kg can pinch very hard and cause hematomas. 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. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 15x3x6 / N38, we recommend utilizing two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. 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 roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. 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.

This model is characterized by dimensions 15x3x6 mm, which, at a weight of 2.03 g, makes it an element with high energy density. It is a magnetic block with dimensions 15x3x6 mm and a self-weight of 2.03 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Strengths

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

They do not lose power, even over approximately 10 years – the drop in power is only ~1% (according to tests),
They do not lose their magnetic properties even under close interference source,
Thanks to the metallic finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an aesthetic appearance,
Magnetic induction on the working part of the magnet remains impressive,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of accurate creating and adapting to specific requirements,
Universal use in high-tech industry – they serve a role in hard drives, brushless drives, medical equipment, and modern systems.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
Neodymium magnets decrease their power 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 stability even at temperatures up to 230°C
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
Limited possibility of producing threads in the magnet and complex forms - recommended is a housing - mounting mechanism.
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. It is also worth noting that small elements of these products are able to complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

The load parameter shown concerns the limit force, measured under ideal test conditions, specifically:

on a block made of mild steel, optimally conducting the magnetic field
whose transverse dimension reaches at least 10 mm
characterized by smoothness
without the slightest clearance between the magnet and steel
under vertical application of breakaway force (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Determinants of practical lifting force of a magnet

Bear in mind that the magnet holding may be lower depending on the following factors, in order of importance:

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, 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).
Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.

Safe handling of neodymium magnets

Swallowing risk

Always store magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are very dangerous.

Medical implants

For implant holders: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or request help to work with the magnets.

Bodily injuries

Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

GPS Danger

GPS units and mobile phones are highly sensitive to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.

Machining danger

Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.

Do not underestimate power

Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and respect their force.

Protective goggles

Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Protect data

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

Permanent damage

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

Nickel allergy

A percentage of the population experience a sensitization to Ni, which is the common plating for neodymium magnets. Extended handling may cause a rash. We suggest wear protective gloves.
