Pulling power weakens drastically with every subsequent millimeter of distance. Remember that even the smallest gap (e.g., dirt, varnish, veneer) strongly weakens the grip. Magnetic products operate most effectively at the point of direct contact; distance nullifies the force. Analyze how rapidly the pull force drop, when the product does not touch flatly to the steel surface. When designing the arrangement, avoid redundant distances.

The following data shows the theoretical holding capacity needed to cause the shifting of the magnet vertically against a upright metal surface (assuming standard friction). This value is relative to the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MPL 5x5x1.2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.13 kg / 0.29 lbs 132.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.19 lbs 88.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.10 lbs 44.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.22 kg / 0.49 lbs 220.0 g / 2.2 N

When mounting a magnet on a upright plane (e.g., a fridge), it will only hold just approx. 20%-30% of its maximum pull force. Gravity as well as a low friction coefficient cause that holders move down faster than they detach. Planning a vertical fastening? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a noticeably lighter weight. Using a rubber pad can drastically increase the grip.

12 mm	100%	0.44 kg / 0.97 lbs 440.0 g / 4.3 N

A thin sheet cannot conduct the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To achieve 100% of this neodymium's power, you need a suitably thick backing of steel. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the product works worse. We recommend selecting the steel thickness according to the table below.

Table 5: Thermal stability (stability) - resistance threshold
MPL 5x5x1.2 / N38

Standard neodymium magnets change their properties strength after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly destroy this product. As the temperature rises, the magnet's force momentarily lowers. Refrain from using this product near heat sources higher than its working range. Exceeding the critical threshold will cause destruction of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) may lose charge permanently at lower temperatures compared to rod magnets. Red status in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums interact from a much further distance than a magnet and sheet setup. The connection of magnet-to-magnet generates a stronger field and a larger range of operation. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the collision energy is extreme. The repulsion force is marginally weaker than the connection force, but still large.
*Field value between like poles is approximately ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Important: Estimates refer to shear force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to electronics and pacemakers. These neodymiums generate a field that disrupts operation of digital equipment. Remember: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a collision with steel causes immediate chipping. Control the attraction moment – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or painful pinches to skin. Hold the magnet firmly during mounting so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear safety glasses when playing with large magnets.

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. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Steel saturation

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

3. Thermal stability

*For standard magnets, 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) = 0.30

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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 5x5x1.2 mm and a weight of 0.22 g, guarantees the highest quality connection. As a block magnet with high power (approx. 0.44 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.

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 0.44 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 wind generators and material handling systems. They work great as fasteners under tiles, wood, or glass. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 5x5x1.2 / 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 5x5x1.2 / N38 model is magnetized through the thickness (dimension 1.2 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 (5x5 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 5x5x1.2 mm, which, at a weight of 0.22 g, makes it an element with impressive energy density. The key parameter here is the lifting capacity amounting to approximately 0.44 kg (force ~4.28 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:

Their power remains stable, and after approximately ten years it drops only by ~1% (theoretically),
They show high resistance to demagnetization induced by external disturbances,
A magnet with a metallic nickel surface looks better,
Magnets are characterized by huge magnetic induction on the surface,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
In view of the option of accurate forming and adaptation to unique needs, NdFeB magnets can be produced in a wide range of shapes and sizes, which makes them more universal,
Wide application in modern industrial fields – they find application in mass storage devices, drive modules, diagnostic systems, also industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in miniature devices

Cons

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Detachment force of the magnet in optimal conditions – what affects it?

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

using a base made of low-carbon steel, functioning as a circuit closing element
whose transverse dimension is min. 10 mm
with an ideally smooth touching surface
under conditions of ideal adhesion (surface-to-surface)
during pulling in a direction vertical to the mounting surface
in temp. approx. 20°C

Lifting capacity in practice – influencing factors

It is worth knowing that the working load may be lower subject to the following factors, in order of importance:

Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Material composition – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Temperature – temperature increase causes a temporary drop of induction. Check the thermal limit 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 holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.

H&S for magnets

Allergic reactions

Certain individuals suffer from a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Extended handling can result in a rash. We suggest wear protective gloves.

Power loss in heat

Keep cool. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).

Powerful field

Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their force.

Finger safety

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

Keep away from children

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

Machining danger

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

Safe distance

Device Safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).

Compass and GPS

GPS units and mobile phones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Danger to pacemakers

Patients with a ICD have to maintain an absolute distance from magnets. The magnetism can interfere with the operation of the life-saving device.

Risk of cracking

Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.

Danger! More info about hazards in the article: Magnet Safety Guide.
