Magnetic force decreases sharply with every mm of gap. Keep in mind that every additional insulation layer (e.g., dirt, paint, dust) significantly diminishes the holding power. Neodymiums hold strongest during direct contact; gap drastically cuts the power. Notice how flashily the pull force drop, when the magnet does not adhere flatly to the metal substrate. When calculating the assembly, discard redundant distances.

When mounting a holder on a vertical wall (e.g., a fridge), it you can count on only approx. 1/5 of its nominal power. Gravitational force and a weak degree of grip cause that products slide down easier than they pull off. Want to create a wall mount? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a much lighter weight. Utilizing a rubberized layer can effectively improve the result.

A too thin steel is not enough to focus the full magnetic flux, which wastes potential of the magnet. If you attach a powerful product to a weak sheet, the field will penetrate right through and the holding will be smaller. To achieve the maximum of this magnet's power, you need a suitably thick piece of steel. The saturation phenomenon means that on sheet metal structures (e.g., thin profiles), the holder works worse. We suggest choosing the steel cross-section according to the table below.

Ordinary NdFeB products irreversibly lose power above the temperature limit. Protect against heat – excessive heat can irreversibly demagnetize this product. With every degree above norm, the neodymium's force briefly decreases. Do not use this product near heat sources exceeding its safe range. Ignoring the limit will lead to irreversible degradation of magnetism.
*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low Pc) may lose charge permanently at lower temperatures than long magnets. Red status in the table signals a risk of irreversible loss for this specific geometry.

Two magnets interact from a much further distance than a magnet and steel combination. Such a system of magnet-to-magnet creates a more powerful interaction and a wider radius of operation. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when bringing together two magnets, the impact force is huge. The repulsion force is marginally weaker than the attraction, but still significant.
*Flux density in repulsion mode drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
Attention: Estimates apply to sliding force of two same magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a real danger to IT equipment as well as medical implants. These NdFeB products generate a field that disrupts operation of digital equipment. Remember: the unseen radiation penetrates the body and plastic. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Neodymium magnets are delicate – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or painful pinches to skin. Be sure to control the product during installation so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the magnet. Use safety goggles when playing with powerful specimens.

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.
1. Vertical hold

*Caution: On a vertical surface, the magnet holds just ~20% of its nominal pull.

2. Efficiency vs thickness

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

3. Temperature resistance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.31

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 Pc (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 Pc 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.

Model MPL 40x10x5 / N38 features a low profile and professional pulling force, making it an ideal solution for building separators and machines. This magnetic block with a force of 116.27 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.
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. To separate the MPL 40x10x5 / 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 wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. 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 40x10x5 / N38, we recommend utilizing two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).
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 (40x10 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 40x10x5 mm, which, at a weight of 15 g, makes it an element with impressive energy density. The key parameter here is the lifting capacity amounting to approximately 11.85 kg (force ~116.27 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of neodymium magnets.

Pros

Besides their durability, neodymium magnets are valued for these benefits:
  • They retain attractive force for around 10 years – the drop is just ~1% (according to analyses),
  • They possess excellent resistance to magnetic field loss as a result of external magnetic sources,
  • By covering with a smooth layer of silver, the element gains an nice look,
  • Neodymium magnets deliver maximum magnetic induction on a small surface, which allows for strong attraction,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Possibility of accurate forming and adapting to individual requirements,
  • Wide application in high-tech industry – they are commonly used in mass storage devices, brushless drives, diagnostic systems, and modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions

Cons

Disadvantages of neodymium magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
  • NdFeB magnets demagnetize 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 extremely resistant to heat
  • Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • Limited possibility of making threads in the magnet and complex forms - preferred is cover - magnet mounting.
  • Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
  • With large orders the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum lifting force for a neodymium magnet – what contributes to it?

The load parameter shown represents the maximum value, measured under optimal environment, specifically:
  • using a base made of mild steel, functioning as a circuit closing element
  • possessing a thickness of min. 10 mm to avoid saturation
  • characterized by lack of roughness
  • with total lack of distance (no paint)
  • during pulling in a direction perpendicular to the mounting surface
  • at temperature room level

Magnet lifting force in use – key factors

It is worth knowing that the working load will differ subject to the following factors, in order of importance:
  • Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
  • Direction of force – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
  • Base massiveness – insufficiently thick plate causes magnetic saturation, causing part of the power to be wasted to the other side.
  • Chemical composition of the base – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and holding force.
  • Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
  • Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity was measured using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

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

Do not drill into magnets

Dust created during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Medical interference

Individuals with a ICD must keep an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Electronic devices

Data protection: Strong magnets can damage data carriers and delicate electronics (heart implants, medical aids, timepieces).

Eye protection

Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.

Sensitization to coating

Medical facts indicate that nickel (the usual finish) is a potent allergen. For allergy sufferers, refrain from touching magnets with bare hands and opt for versions in plastic housing.

Adults only

Adult use only. Small elements can be swallowed, causing intestinal necrosis. Store out of reach of children and animals.

Operating temperature

Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Conscious usage

Be careful. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.

Hand protection

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