Grip strength drops drastically per each millimeter of spacing. Note that even a very thin break (e.g., dirt, paint, rust) strongly reduces the pull force. Neodymiums operate optimally at the point of direct contact; air break kills the force. See how quickly the load capacity fall, when the magnet does not touch tightly to the steel surface. When designing the mounting, eliminate unnecessary gaps.

The following data indicates the approximate holding capacity required to start the slippage of the magnet downwards against a upright steel wall (considering typical friction). This parameter varies with the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
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 holder on a upright plane (e.g., a fridge), it you can count on only about 1/5 of its nominal power. Gravity and a weak degree of grip mean that magnets slide down easier than they pull off. Designing a wall mount? Note that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the magnet will give way down under a much lighter cargo. Utilizing a rubberized pad can drastically improve the result.

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

A thin sheet cannot take in the entire magnetic field, which weakens actual performance of the holder. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To achieve 100% of this neodymium's power, you require a sufficiently solid backing of metal. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the magnet shows lower pull force. We suggest choosing the steel cross-section according to the table below.

Table 5: Working in heat (material behavior) - thermal limit

Ordinary NdFeB products irreversibly lose power above the temperature limit. Protect against heat – heat can irreversibly destroy this product. With increasing heat, the neodymium's force momentarily decreases. Refrain from using this product near heat sources exceeding its operating temperature limit. Ignoring the limit will lead to destruction of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and steel combination. The setup of two magnets creates a more powerful interaction and a larger range of action. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the pinch force is massive. The repulsion force is a bit weaker than the attraction, but still impressive.
*Flux density for N-N configuration reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
* Calculations show sliding force of a pair of same magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a serious hazard to IT equipment and pacemakers. These NdFeB products produce a field that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field passes through tissues and glass. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - 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 strong collision with metal risks their cracking. Control the attraction moment – a neodymium left loose turns into a projectile. Striking energy can trigger coating fragments or injury to fingers. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the magnet. Wear safety glasses when handling with powerful specimens.

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. Wall mount (shear)

*Caution: On a vertical surface, the magnet retains only ~20% of its nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) severely limits the holding force.

3. Thermal stability

*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

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.

MPL 3x3x2 / N38 - lamellar magnet

0.1722 ZŁ brutto / pcs

Model MPL 15x3x6 / N38 features a flat shape and professional pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 1.90 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating protects 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. Watch your fingers! Magnets with a force of 1.90 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 15x3x6 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as fasteners under tiles, wood, or glass. 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 15x3x6 / N38 model is magnetized axially (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 15x3x6 mm, which, at a weight of 2.03 g, makes it an element with impressive energy density. The key parameter here is the holding force amounting to approximately 1.90 kg (force ~18.68 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Pros and cons of rare earth magnets.

Strengths

Besides their immense field intensity, neodymium magnets offer the following advantages:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
They feature excellent resistance to magnetism drop as a result of opposing magnetic fields,
The use of an refined layer of noble metals (nickel, gold, silver) causes the element to look better,
Neodymium magnets achieve maximum magnetic induction on a their surface, which ensures high operational effectiveness,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of accurate shaping and optimizing to specific conditions,
Huge importance in innovative solutions – they are commonly used in computer drives, drive modules, precision medical tools, and industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions

Cons

What to avoid - cons of neodymium magnets: application proposals

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
Neodymium magnets lose 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
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in creating nuts and complex shapes in magnets, we propose using cover - magnetic mount.
Health risk to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Additionally, small elements of these devices are able to 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

Pull force analysis

Highest magnetic holding force – what affects it?

Information about lifting capacity was determined for ideal contact conditions, including:

using a plate made of low-carbon steel, functioning as a ideal flux conductor
possessing a thickness of min. 10 mm to ensure full flux closure
characterized by even structure
with direct contact (no coatings)
under axial force vector (90-degree angle)
in temp. approx. 20°C

What influences lifting capacity in practice

During everyday use, the actual lifting capacity is determined by several key aspects, listed from the most important:

Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
Angle of force application – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel type – low-carbon steel gives the best results. Alloy steels reduce magnetic properties and holding force.
Smoothness – full contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Precautions when working with neodymium magnets

Risk of cracking

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Life threat

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.

Compass and GPS

A strong magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.

Heat sensitivity

Keep cool. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).

Mechanical processing

Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.

Electronic devices

Do not bring magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.

Safe operation

Exercise caution. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can react.

Avoid contact if allergic

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.

Bodily injuries

Big blocks can break fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.

Swallowing risk

These products are not suitable for play. Eating a few magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and requires immediate surgery.
