Grip strength drops significantly with every mm of distance. Remember that even a microscopic distance (e.g., contamination, varnish, dust) significantly diminishes the holding power. Neodymiums hold most effectively during direct contact; air break weakens the power. Observe how quickly the pull force fall, when the product does not touch directly to the steel surface. When calculating the assembly, discard unnecessary gaps.

The following data calculates the estimated weight limit sufficient to start the shifting of the magnet vertically on a upright steel wall (assuming typical friction). This value is relative to the distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 10x10x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.70 kg / 1.53 lbs 696.0 g / 6.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.46 kg / 1.02 lbs 464.0 g / 4.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.23 kg / 0.51 lbs 232.0 g / 2.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.16 kg / 2.56 lbs 1160.0 g / 11.4 N

When placing a magnet on a vertical plane (e.g., a board), it will only hold just approx. 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that products slip easier than they detach. Designing a hanger? Remember that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the magnet will slip down under a noticeably lighter load. Utilizing a rubberized pad can drastically improve the result.

Table 4: Material efficiency (saturation) - power losses
MPL 10x10x3 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.23 kg / 0.51 lbs 232.0 g / 2.3 N

2 mm	50%	1.16 kg / 2.56 lbs 1160.0 g / 11.4 N
3 mm	75%	1.74 kg / 3.84 lbs 1740.0 g / 17.1 N
5 mm	100%	2.32 kg / 5.11 lbs 2320.0 g / 22.8 N
10 mm	100%	2.32 kg / 5.11 lbs 2320.0 g / 22.8 N
11 mm	100%	2.32 kg / 5.11 lbs 2320.0 g / 22.8 N
12 mm	100%	2.32 kg / 5.11 lbs 2320.0 g / 22.8 N

A too thin steel cannot absorb the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a thin surface, the field will penetrate right through and the attraction force will be weaker. To achieve 100% of this neodymium's potential, you require a sufficiently solid element of metal. The saturation effect causes that on delicate walls (e.g., appliance housings), the holder shows lower pull force. We suggest choosing the steel thickness based on the following data.

Table 5: Working in heat (stability) - power drop

40 °C	-2.2%	2.27 kg / 5.00 lbs 2269.0 g / 22.3 N	OK

100 °C	-28.8%	1.65 kg / 3.64 lbs 1651.8 g / 16.2 N

Classic neodymiums lose power after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently damage this magnet. With increasing heat, the neodymium's power temporarily lowers. Avoid using this product close to ovens exceeding its operating temperature limit. Exceeding the critical threshold will lead to destruction of magnetism.

*Engineering note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) are more susceptible to demagnetization sooner compared to rod magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a wider radius than a magnet and steel combination. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the impact force is extreme. The repulsion force is marginally weaker than the connection force, but still impressive.
*Field value for N-N configuration reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Note: Figures demonstrate shear force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to electronics and pacemakers. These magnets generate a field that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field acts through matter and glass. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - warning

Neodymium magnets are prone to chipping – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can cause material chips or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Use safety goggles when handling with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

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

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) significantly 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) = 0.36

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.

NCM 20x13.5x5 / N38 - channel magnetic holder

7.29 ZŁ brutto / pcs

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 10x10x3 mm and a weight of 2.25 g, guarantees premium class connection. As a block magnet with high power (approx. 2.32 kg), this product is available off-the-shelf from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

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 2.32 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.

Plate magnets MPL 10x10x3 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 2.32 kg), they are ideal as closers in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 10x10x3 / N38, it is best to use two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 10x10x3 / N38 model is magnetized through the thickness (dimension 3 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 (10x10 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 10x10x3 mm, which, at a weight of 2.25 g, makes it an element with high energy density. It is a magnetic block with dimensions 10x10x3 mm and a self-weight of 2.25 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros as well as cons of rare earth magnets.

Advantages

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

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
Magnets very well resist against demagnetization caused by external fields,
In other words, due to the smooth finish of nickel, the element gains visual value,
The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Due to the ability of free shaping and adaptation to individualized needs, magnetic components can be produced in a variety of shapes and sizes, which makes them more universal,
Versatile presence in modern technologies – they serve a role in hard drives, drive modules, precision medical tools, and multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields 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 drop of power (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 extremely resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Limited possibility of making threads in the magnet and complex shapes - recommended is a housing - magnet mounting.
Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to complicate diagnosis medical when they are in the body.
With mass production the cost of neodymium magnets is a challenge,

Holding force characteristics

Maximum magnetic pulling force – what it depends on?

Information about lifting capacity is the result of a measurement for the most favorable conditions, including:

on a plate made of mild steel, optimally conducting the magnetic flux
with a cross-section of at least 10 mm
with an polished contact surface
under conditions of gap-free contact (metal-to-metal)
for force applied at a right angle (pull-off, not shear)
at conditions approx. 20°C

Impact of factors on magnetic holding capacity in practice

It is worth knowing that the application force will differ influenced by the following factors, in order of importance:

Distance – existence of foreign body (rust, tape, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Angle of force application – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Steel type – mild steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
Surface finish – ideal contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
Thermal environment – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Safe handling of neodymium magnets

Pinching danger

Risk of injury: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.

Do not give to children

These products are not suitable for play. Swallowing a few magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires urgent medical intervention.

Nickel allergy

A percentage of the population suffer from a contact allergy to Ni, which is the common plating for NdFeB magnets. Extended handling might lead to dermatitis. We suggest wear protective gloves.

Health Danger

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Machining danger

Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Heat sensitivity

Keep cool. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Shattering risk

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets will cause them cracking into shards.

Safe distance

Do not bring magnets near a purse, computer, or screen. The magnetism can destroy these devices and erase data from cards.

Keep away from electronics

An intense magnetic field disrupts the operation of compasses in smartphones and navigation systems. Keep magnets near a device to prevent breaking the sensors.

Powerful field

Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
