Pulling power drops significantly with every subsequent millimeter of gap. Note that even the smallest gap (e.g., contamination, paint, veneer) strongly diminishes the holding power. Magnets work optimally in perfect adhesion; air break drastically cuts the power. See how flashily the parameters drop, when the product does not touch tightly to the steel surface. When calculating the arrangement, avoid redundant distances.

The following data defines the approximate shear load necessary to start the downward movement of the magnet downwards against a upright steel plate (considering typical friction). This value varies with the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 15x5x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.96 kg / 2.12 pounds 960.0 g / 9.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.64 kg / 1.41 pounds 640.0 g / 6.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.32 kg / 0.71 pounds 320.0 g / 3.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.60 kg / 3.53 pounds 1600.0 g / 15.7 N

When mounting a holder on a upright plane (e.g., a board), it will only hold just approx. 1/5 of its nominal power. Gravity as well as a low friction coefficient cause that holders slip easier than they detach. Planning a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the element will slip down under a noticeably lighter load. Application of an anti-slip layer can significantly improve the result.

A thin metal plate cannot take in the entire magnetic field, which wastes potential of the magnet. If you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To utilize the maximum of this magnet's potential, you need a suitably thick piece of metal. The saturation phenomenon means that on thin elements (e.g., thin profiles), the holder holds weaker. We recommend selecting the steel thickness according to the table below.

Ordinary NdFeB products change their properties strength above the temperature limit. Watch out for overheating – excessive heat can permanently demagnetize this magnet. With every degree above norm, the magnet's power briefly drops. Avoid using this magnet near heat sources exceeding its working range. Too high temperature will cause irreversible degradation of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) risk losing magnetic properties at lower temperatures than taller cylinders. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a much further distance than a magnet and steel setup. The connection of two magnets generates a stronger field and a larger range of operation. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is marginally weaker than the attraction, but still significant.
*Flux density in repulsion mode is approximately ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Important: Figures refer to friction force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a real danger to electronic devices and medical implants. These neodymiums generate a field that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field acts through matter and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Neodymium magnets are delicate – a strong collision with metal risks their cracking. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can cause material chips or dangerous crushing to skin. Always hold the magnet during installation so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when playing 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Note: On a vertical wall, the magnet holds just approx. 20-30% of its max power.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) severely reduces the holding force.

3. Thermal stability

*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) = 0.60

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 plate magnet made of NdFeB material, which, with dimensions of 15x5x5 mm and a weight of 2.81 g, guarantees the highest quality connection. As a block magnet with high power (approx. 3.20 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 block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 15x5x5 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. 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 generators and material handling systems. 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 15x5x5 / N38, we recommend utilizing 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 15x5x5 / N38 model is magnetized through the thickness (dimension 5 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 15x5x5 mm, which, at a weight of 2.81 g, makes it an element with high energy density. It is a magnetic block with dimensions 15x5x5 mm and a self-weight of 2.81 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of neodymium magnets.

Advantages

Apart from their consistent holding force, neodymium magnets have these key benefits:

They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
Neodymium magnets remain highly resistant to demagnetization caused by external magnetic fields,
Thanks to the elegant finish, the plating of nickel, gold-plated, or silver gives an modern appearance,
Neodymium magnets deliver maximum magnetic induction on a their surface, which allows for strong attraction,
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...
Thanks to flexibility in constructing and the ability to customize to specific needs,
Huge importance in innovative solutions – they find application in mass storage devices, drive modules, diagnostic systems, also multitasking production systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated shapes.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Highest magnetic holding force – what contributes to it?

The declared magnet strength concerns the maximum value, recorded under laboratory conditions, specifically:

on a base made of mild steel, effectively closing the magnetic field
with a thickness of at least 10 mm
with an ground touching surface
without the slightest clearance between the magnet and steel
under axial application of breakaway force (90-degree angle)
at ambient temperature room level

Determinants of practical lifting force of a magnet

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

Clearance – the presence of foreign body (paint, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Angle of force application – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Chemical composition of the base – mild steel gives the best results. Higher carbon content decrease magnetic permeability and holding force.
Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Warnings

Avoid contact if allergic

It is widely known that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, avoid direct skin contact or choose encased magnets.

Powerful field

Use magnets consciously. Their huge power can surprise even experienced users. Be vigilant and respect their force.

Mechanical processing

Powder created during machining of magnets is flammable. Do not drill into magnets unless you are an expert.

Keep away from electronics

A powerful magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to avoid damaging the sensors.

Demagnetization risk

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Keep away from computers

Device Safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).

Crushing risk

Big blocks can break fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.

Magnets are brittle

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

ICD Warning

Patients with a ICD should maintain an absolute distance from magnets. The magnetic field can stop the functioning of the implant.

No play value

Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Store away from children and animals.
