Magnetic force decreases drastically per each millimeter of spacing. Remember that even a microscopic distance (e.g., contamination, varnish, veneer) significantly weakens the grip. Magnets operate most effectively at the point of direct contact; air break kills the force. Notice how flashily the load capacity fall, when the magnet does not touch flatly to the steel surface. When calculating the assembly, eliminate unnecessary gaps.

The following data presents the theoretical shear load required to start the shifting of the magnet down against a vertical steel wall (assuming typical friction coefficient). The holding force depends on the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MPL 25x10x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.24 kg / 2.74 LBS 1242.0 g / 12.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.83 kg / 1.83 LBS 828.0 g / 8.1 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.07 kg / 4.56 LBS 2070.0 g / 20.3 N

When hanging a element on a upright plane (e.g., a fridge), it will only hold only approx. 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that magnets slide down easier than they detach. Planning a wall mount? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a much lighter weight. Application of an anti-slip pad can significantly raise the stability.

A thin sheet is not enough to absorb the full magnetic flux, which squanders power of the holder. If you install a neodymium to a too thin substrate, the flux will pass right through and the attraction force will be weaker. To achieve the maximum of this magnet's power, you need a suitably thick element of metal. The saturation effect causes that on thin elements (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel cross-section according to the table below.

Ordinary NdFeB products change their properties power past the thermal threshold. Protect against heat – heat can irreversibly damage this magnet. With every degree above norm, the magnet's capacity momentarily decreases. Do not use this product close to heaters exceeding its operating temperature limit. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress compared to rod magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnetic products interact from a significantly greater distance than a magnet and sheet setup. Such a system of two magnets creates a more powerful interaction and a further horizon of performance. Planning to create a powerful holder? Apply two magnets instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the collision energy is huge. The repulsion force is slightly lower than the attraction, but still large.
*Flux density between like poles reaches ~0 Gs in the exact middle between the magnets (due to field cancellation).
* Calculations show shear force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Safety (HSE) (electronics) - precautionary measures

A strong magnetic field is a large risk to electronics as well as pacemakers. These NdFeB products produce a flux that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Table 8: Dynamics (cracking risk) - warning
MPL 25x10x3 / N38

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

100 mm	86.48 km/h (24.02 m/s)	1.62 J

NdFeB products are very brittle – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can trigger coating fragments or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Wear safety glasses when playing with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

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

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) significantly 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) = 0.25

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 an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 25x10x3 mm and a weight of 5.63 g, guarantees the highest quality connection. This magnetic block with a force of 40.56 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating protects 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. Watch your fingers! Magnets with a force of 4.14 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 25x10x3 / 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 hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 25x10x3 / N38, it is best to use strong epoxy glues (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. In practice, this means that this magnet has the greatest attraction force on its main planes (25x10 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 25x10x3 mm, which, at a weight of 5.63 g, makes it an element with impressive energy density. The key parameter here is the holding force amounting to approximately 4.14 kg (force ~40.56 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Pros and cons of Nd₂Fe₁₄B magnets.

Benefits

In addition to their pulling strength, neodymium magnets provide the following advantages:

They retain full power for almost 10 years – the drop is just ~1% (according to analyses),
Neodymium magnets prove to be extremely resistant to demagnetization caused by external magnetic fields,
The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of individual shaping and adjusting to atypical conditions,
Versatile presence in future technologies – they serve a role in mass storage devices, brushless drives, diagnostic systems, also complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in compact constructions

Disadvantages

Characteristics of disadvantages of neodymium magnets: tips and applications.

Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complex forms.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Highest magnetic holding force – what affects it?

The force parameter is a measurement result performed under specific, ideal conditions:

using a sheet made of low-carbon steel, acting as a magnetic yoke
possessing a thickness of minimum 10 mm to ensure full flux closure
with an ideally smooth contact surface
with direct contact (no impurities)
under perpendicular force vector (90-degree angle)
at temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

Please note that the application force will differ influenced by elements below, in order of importance:

Distance (between the magnet and the plate), since even a very small distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
Steel thickness – insufficiently thick plate does not accept the full field, causing part of the power to be wasted to the other side.
Steel grade – ideal substrate is high-permeability steel. Hardened steels may attract less.
Plate texture – ground elements ensure maximum contact, which improves force. Uneven metal weaken the grip.
Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Precautions when working with neodymium magnets

Phone sensors

GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.

Danger to the youngest

Only for adults. Small elements can be swallowed, causing intestinal necrosis. Keep away from kids and pets.

Material brittleness

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

Safe operation

Use magnets consciously. Their huge power can shock even professionals. Be vigilant and do not underestimate their power.

Pinching danger

Danger of trauma: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Avoid contact if allergic

It is widely known that nickel (standard magnet coating) is a strong allergen. If you have an allergy, avoid direct skin contact or opt for coated magnets.

Dust is flammable

Dust generated during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Implant safety

For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or request help to handle the magnets.

Heat warning

Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Protect data

Avoid bringing magnets close to a purse, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.
