Magnetic force decreases significantly per each millimeter of gap. Keep in mind that even a microscopic distance (e.g., contamination, paint, dust) significantly reduces the pull force. Neodymiums hold strongest during direct contact; distance drastically cuts the force. Observe how quickly the load capacity fall, when the magnet does not touch tightly to the steel surface. When calculating the arrangement, avoid unnecessary gaps.

This section presents the approximate weight limit necessary to start the downward movement of the magnet vertically against a vertical metal surface (considering standard friction coefficient). This value varies with the separation distance between the magnet and the metal.

When placing a magnet on a upright wall (e.g., a board), it will only hold just about 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip mean that holders move down easier than they pull off. Want to create a vertical fastening? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a much lighter weight. Using a rubber pad can effectively raise the stability.

A too thin steel is incapable of focus the full magnetic flux, which weakens actual performance of the magnet. Should you attach a powerful product to a thin surface, the field will pass right through and the holding will be smaller. To utilize the maximum of this magnet's power, you require a sufficiently solid backing of steel. The material oversaturation means that on delicate walls (e.g., thin profiles), the magnet holds weaker. We suggest choosing the steel dimension based on the following data.

Ordinary NdFeB products lose parameters after exceeding the maximum temperature. Avoid high temperatures – heat can permanently damage this magnet. As the temperature rises, the magnet's capacity temporarily lowers. Do not use this product close to heaters exceeding its safe range. Too high temperature will result in destruction of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently sooner than long magnets. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnetic products attract each other 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 action. Designing a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still significant.
*Field value for N-N configuration reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Note: Estimates refer to friction force of dual matching magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a serious hazard to electronics as well as medical implants. These magnets generate a field that disrupts operation of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and glass. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a violent impact against metal risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can cause material chips or dangerous crushing to skin. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear safety glasses when playing with powerful specimens.

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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Note: On a vertical wall, the magnet holds merely ~20% of its perpendicular strength.

2. Steel saturation

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

3. Heat tolerance

*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) = 0.25

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 an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 25x10x3 mm and a weight of 5.63 g, guarantees premium class connection. This magnetic block with a force of 40.56 N is ready for shipment in 24h, allowing for rapid realization of your project. 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. To separate the MPL 25x10x3 / 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. Thanks to the flat surface and high force (approx. 4.14 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.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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 25x10x3 / 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. 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 25x10x3 mm, which, at a weight of 5.63 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 4.14 kg (force ~40.56 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of neodymium magnets.

Benefits

Apart from their strong power, neodymium magnets have these key benefits:

Their power remains stable, and after approximately 10 years it decreases only by ~1% (theoretically),
Neodymium magnets prove to be remarkably resistant to demagnetization caused by external field sources,
By covering with a smooth coating of gold, the element presents an professional look,
The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
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...
Possibility of detailed shaping and optimizing to atypical applications,
Huge importance in high-tech industry – they find application in HDD drives, drive modules, medical equipment, as well as multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 very resistant to heat
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
Due to limitations in creating nuts and complicated shapes in magnets, we propose using a housing - magnetic mount.
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 can be problematic in diagnostics medical after entering the body.
Due to complex production process, their price is higher than average,

Lifting parameters

Maximum magnetic pulling force – what contributes to it?

The specified lifting capacity concerns the maximum value, obtained under optimal environment, specifically:

using a sheet made of mild steel, functioning as a circuit closing element
with a thickness no less than 10 mm
with an ideally smooth contact surface
under conditions of no distance (metal-to-metal)
under perpendicular application of breakaway force (90-degree angle)
at temperature approx. 20 degrees Celsius

Determinants of practical lifting force of a magnet

In real-world applications, the actual lifting capacity is determined by several key aspects, ranked from most significant:

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – note 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.
Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped to the other side.
Chemical composition of the base – mild steel attracts best. Alloy admixtures decrease magnetic properties and holding force.
Plate texture – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.

Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets

Keep away from electronics

GPS units and mobile phones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Safe operation

Handle magnets with awareness. Their immense force can surprise even professionals. Plan your moves and do not underestimate their force.

Medical implants

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Machining danger

Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Fragile material

Neodymium magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets will cause them breaking into small pieces.

Operating temperature

Keep cool. NdFeB magnets are sensitive to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Nickel coating and allergies

Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands and choose versions in plastic housing.

Hand protection

Pinching hazard: The attraction force is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.

Protect data

Do not bring magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.

Swallowing risk

Always keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are fatal.
