Pulling power decreases sharply with every subsequent millimeter of spacing. Remember that even the smallest gap (e.g., contamination, paint, dust) strongly diminishes the holding power. Magnets operate strongest in perfect adhesion; air break nullifies the power. Observe how rapidly the pull force drop, when the magnet does not adhere tightly to the steel surface. When designing the assembly, discard additional spacers.

The following data presents the estimated holding capacity needed to initiate the slippage of the magnet downwards against a vertical metal surface (considering standard friction). This parameter varies with the separation distance between the magnet and the surface.

When placing a element on a vertical wall (e.g., a board), it will maintain just about 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip mean that products move down faster than they detach. Planning a wall mount? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a noticeably lighter cargo. Using a rubber layer can drastically raise the stability.

A thin sheet is unable to focus the entire magnetic field, which wastes potential of the holder. If you install a neodymium to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this magnet's power, you need a suitably thick backing of steel. The saturation phenomenon means that on sheet metal structures (e.g., thin profiles), the holder works worse. We advise picking the steel cross-section from these parameters.

Classic neodymiums lose parameters past the thermal threshold. Protect against heat – high temperature can permanently demagnetize this magnet. As the temperature rises, the magnet's capacity momentarily lowers. Do not use this magnet in hot environments exceeding its working range. Ignoring the limit will lead to irreversible degradation of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) may lose charge permanently sooner than long magnets. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two magnets attract each other from a much further distance than a neodymium and metal setup. The connection of two magnets produces a massive flux and a wider radius of action. Want to build a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the collision energy is huge. The levitation is a bit weaker than the connection force, but still impressive.
*Flux density in repulsion mode reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Attention: Figures show sliding force of two matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to electronic devices and medical implants. These magnets generate a field that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field penetrates the body and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Neodymium magnets are very brittle – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Kinetic force can destroy the magnet or injury to fingers. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when handling with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Shear force

*Warning: On a vertical wall, the magnet holds only approx. 20-30% of its nominal pull.

2. Steel thickness impact

*Thin steel (e.g. computer case) significantly weakens the holding force.

3. Thermal stability

*For N38 grade, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.33

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 80x40x15 mm and a weight of 360 g, guarantees premium class connection. As a block magnet with high power (approx. 73.57 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is sliding 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 73.57 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 generators and material handling systems. Thanks to the flat surface and high force (approx. 73.57 kg), they are ideal as closers in furniture making and mounting elements in automation. 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 80x40x15 / N38, we recommend utilizing 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.

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 (80x40 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 80x40x15 mm, which, at a weight of 360 g, makes it an element with high energy density. It is a magnetic block with dimensions 80x40x15 mm and a self-weight of 360 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They do not lose magnetism, even during approximately 10 years – the reduction in power is only ~1% (theoretically),
They have excellent resistance to magnetic field loss when exposed to external fields,
A magnet with a metallic silver surface has an effective appearance,
They feature high magnetic induction at the operating surface, which increases their power,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Thanks to modularity in constructing and the capacity to adapt to specific needs,
Key role in modern technologies – they serve a role in magnetic memories, electric drive systems, medical equipment, also industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions

Disadvantages

Cons of neodymium magnets and ways of using them

At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
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, when using outdoors
We recommend casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex forms.
Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these products can disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

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

The force parameter is a theoretical maximum value performed under the following configuration:

using a plate made of low-carbon steel, acting as a magnetic yoke
possessing a thickness of minimum 10 mm to ensure full flux closure
with a plane free of scratches
under conditions of no distance (metal-to-metal)
under axial force vector (90-degree angle)
in stable room temperature

Key elements affecting lifting force

In real-world applications, the real power is determined by a number of factors, presented from crucial:

Air gap (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
Load vector – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Steel grade – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface structure – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.

Safe handling of NdFeB magnets

Do not overheat magnets

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Keep away from computers

Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.

Respect the power

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

Dust explosion hazard

Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

Material brittleness

Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. We recommend safety glasses.

Implant safety

People with a ICD have to maintain an safe separation from magnets. The magnetism can interfere with the operation of the implant.

Precision electronics

Remember: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your phone, tablet, and GPS.

Allergic reactions

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease working with magnets and use protective gear.

Swallowing risk

Only for adults. Tiny parts pose a choking risk, causing serious injuries. Store away from kids and pets.

Crushing risk

Big blocks can break fingers instantly. Never place your hand betwixt two attracting surfaces.
