Grip strength decreases drastically per each millimeter of spacing. Keep in mind that even the smallest gap (e.g., contamination, varnish, dust) significantly weakens the grip. Magnets work strongest in perfect adhesion; air break drastically cuts the power. See how flashily the pull force drop, when the magnet does not adhere flatly to the steel surface. When designing the mounting, eliminate additional spacers.

The table below defines the estimated weight limit needed to cause the downward movement of the magnet downwards along a upright steel plate (assuming typical friction). This value varies with the distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 30x10x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.64 kg / 8.02 pounds 3639.0 g / 35.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.43 kg / 5.35 pounds 2426.0 g / 23.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.21 kg / 2.67 pounds 1213.0 g / 11.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	6.07 kg / 13.37 pounds 6065.0 g / 59.5 N

When hanging a holder on a upright surface (e.g., a fridge), it you can count on barely about 20%-30% of its nominal power. Gravity as well as a low friction coefficient mean that holders move down faster than they detach. Planning a vertical fastening? Consider that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will slip down under a significantly smaller load. Utilizing a rubberized layer can significantly increase the grip.

12 mm	100%	12.13 kg / 26.74 pounds 12130.0 g / 119.0 N

A thin sheet is unable to take in the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To utilize 100% of this neodymium's power, you require a sufficiently solid piece of metal. The saturation effect means that on thin elements (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel dimension from these parameters.

Ordinary NdFeB products change their properties power after exceeding the maximum temperature. Watch out for overheating – heat can permanently demagnetize this product. With every degree above norm, the magnet's force briefly drops. Do not use this product close to ovens exceeding its operating temperature limit. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) risk losing magnetic properties under lower heat stress than long magnets. The danger warning in the table signals permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and steel combination. Such a system of two magnets creates a more powerful interaction and a larger range of action. Designing a strong closure? Use a pair of magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the pinch force is huge. The levitation is slightly lower than the connection force, but still significant.
*Field value in repulsion mode reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
Important: Figures apply to shear force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to electronic devices and pacemakers. These neodymiums generate a flux that disrupts operation of sensitive medical devices. Remember: the unseen radiation acts through matter and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can cause material chips or injury to skin. Hold the magnet firmly during mounting so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the magnet. Use safety goggles when handling with powerful specimens.

Corrosion 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. Buoyancy helps in lifting finds.

1. Vertical hold

*Warning: On a vertical surface, the magnet retains merely ~20% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Temperature resistance

*For standard magnets, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.51

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.

1.697 ZŁ brutto / pcs

Component MPL 30x10x8 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 12.13 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. Watch your fingers! Magnets with a force of 12.13 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 30x10x8 / N38 are the foundation for many industrial devices, such as filters catching filings 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.

For mounting flat magnets MPL 30x10x8 / N38, it is best to use strong epoxy glues (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. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 30x10x8 / N38 model is magnetized axially (dimension 8 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. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 30x10x8 mm, which, at a weight of 18 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 12.13 kg (force ~119.04 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Strengths

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (in testing),
They are extremely resistant to demagnetization induced by presence of other magnetic fields,
In other words, due to the glossy surface of silver, the element gains visual value,
Magnets exhibit maximum magnetic induction on the surface,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
Possibility of accurate modeling and adapting to defined applications,
Wide application in future technologies – they are utilized in HDD drives, brushless drives, diagnostic systems, as well as modern systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

What to avoid - cons of neodymium magnets and ways of using them

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets decrease their strength 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 while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
Limited possibility of creating nuts in the magnet and complicated shapes - preferred is cover - magnet mounting.
Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these products can complicate diagnosis medical after entering the body.
With mass production the cost of neodymium magnets is a challenge,

Pull force analysis

Maximum lifting capacity of the magnet – what contributes to it?

The force parameter is a theoretical maximum value executed under specific, ideal conditions:

on a block made of structural steel, perfectly concentrating the magnetic flux
with a thickness of at least 10 mm
characterized by lack of roughness
with total lack of distance (no impurities)
during detachment in a direction perpendicular to the plane
in neutral thermal conditions

Practical aspects of lifting capacity – factors

Holding efficiency impacted by working environment parameters, including (from most important):

Distance – the presence of any layer (rust, tape, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be escaped to the other side.
Steel grade – the best choice is pure iron steel. Hardened steels may attract less.
Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.

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 load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.

Safety rules for work with neodymium magnets

Machining danger

Dust created during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.

Warning for allergy sufferers

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop working with magnets and use protective gear.

Beware of splinters

Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them shattering into shards.

Danger to pacemakers

Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or request help to work with the magnets.

Power loss in heat

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

Swallowing risk

Neodymium magnets are not suitable for play. Swallowing multiple magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates immediate surgery.

GPS Danger

An intense magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Maintain magnets near a device to avoid damaging the sensors.

Protect data

Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.

Crushing force

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

Do not underestimate power

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