1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains merely approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

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

3. Heat tolerance

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.35

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 35x35x10 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 263.71 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 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. To separate the MPL 35x35x10 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
Plate magnets MPL 35x35x10 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 26.88 kg), they are ideal as hidden locks 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 35x35x10 / N38, we recommend utilizing strong epoxy glues (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. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.
The presented product is a neodymium magnet with precisely defined parameters: 35 mm (length), 35 mm (width), and 10 mm (thickness). It is a magnetic block with dimensions 35x35x10 mm and a self-weight of 91.88 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros and cons of Nd2Fe14B magnets.

Pros

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose power, even during approximately ten years – the reduction in lifting capacity is only ~1% (theoretically),
  • Neodymium magnets prove to be extremely resistant to demagnetization caused by external interference,
  • In other words, due to the glossy layer of gold, the element gains a professional look,
  • They feature high magnetic induction at the operating surface, which affects their effectiveness,
  • 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...
  • Considering the possibility of flexible shaping and adaptation to specialized solutions, neodymium magnets can be produced in a broad palette of geometric configurations, which increases their versatility,
  • Wide application in future technologies – they are used in magnetic memories, drive modules, precision medical tools, as well as industrial machines.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Drawbacks and weaknesses of neodymium magnets and ways of using them
  • They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
  • Neodymium magnets lose their strength 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 stability even at temperatures up to 230°C
  • Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Limited possibility of producing nuts in the magnet and complicated shapes - preferred is cover - magnetic holder.
  • Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
  • With budget limitations the cost of neodymium magnets can be a barrier,

Holding force characteristics

Highest magnetic holding forcewhat it depends on?

The declared magnet strength refers to the limit force, obtained under optimal environment, namely:
  • on a block made of mild steel, optimally conducting the magnetic field
  • with a cross-section minimum 10 mm
  • with an ideally smooth touching surface
  • with total lack of distance (without coatings)
  • under vertical force direction (90-degree angle)
  • in stable room temperature

Magnet lifting force in use – key factors

In practice, the actual lifting capacity is determined by several key aspects, presented from crucial:
  • Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Load vector – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
  • Plate thickness – too thin sheet does not accept the full field, causing part of the power to be wasted into the air.
  • Steel grade – ideal substrate is pure iron steel. Cast iron may attract less.
  • Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the holding force.

Precautions when working with NdFeB magnets
Phone sensors

An intense magnetic field disrupts the operation of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to avoid damaging the sensors.

Threat to electronics

Avoid bringing magnets close to a purse, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.

Sensitization to coating

Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands and select coated magnets.

Fire warning

Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

No play value

Product intended for adults. Tiny parts pose a choking risk, leading to severe trauma. Store away from children and animals.

Conscious usage

Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Medical implants

Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Shattering risk

Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.

Crushing force

Big blocks can crush fingers in a fraction of a second. Never place your hand between two strong magnets.

Power loss in heat

Do not overheat. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
