1. Sliding resistance

*Warning: On a vertical wall, the magnet holds only a fraction of its perpendicular strength.

2. Steel saturation

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

3. Heat tolerance

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.36

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.

Field Strength

Other offers

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 10x10x3 mm and a weight of 2.25 g, guarantees premium class connection. As a magnetic bar with high power (approx. 2.32 kg), this product is available immediately from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.
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. Watch your fingers! Magnets with a force of 2.32 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
Plate magnets MPL 10x10x3 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. 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.
Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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).
Standardly, the MPL 10x10x3 / N38 model is magnetized axially (dimension 3 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (10x10 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.
The presented product is a neodymium magnet with precisely defined parameters: 10 mm (length), 10 mm (width), and 3 mm (thickness). The key parameter here is the holding force amounting to approximately 2.32 kg (force ~22.77 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of Nd2Fe14B magnets.

Benefits

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • Their power is maintained, and after around 10 years it decreases only by ~1% (theoretically),
  • They possess excellent resistance to magnetic field loss as a result of opposing magnetic fields,
  • A magnet with a metallic gold surface has an effective appearance,
  • Magnetic induction on the working part of the magnet remains impressive,
  • Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
  • Thanks to versatility in shaping and the ability to customize to individual projects,
  • Versatile presence in future technologies – they are utilized in computer drives, motor assemblies, medical equipment, also other advanced devices.
  • Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of neodymium magnets:
  • To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
  • We suggest cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
  • Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, tiny parts 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

Magnetic strength at its maximum – what it depends on?

Holding force of 2.32 kg is a measurement result conducted under specific, ideal conditions:
  • on a base made of mild steel, optimally conducting the magnetic flux
  • with a thickness of at least 10 mm
  • characterized by smoothness
  • without the slightest air gap between the magnet and steel
  • under axial force vector (90-degree angle)
  • at standard ambient temperature

Lifting capacity in real conditions – factors

Please note that the working load may be lower depending on the following factors, in order of importance:
  • Distance (between the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
  • Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be escaped to the other side.
  • Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
  • Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
  • Temperature – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Safety rules for work with neodymium magnets
Respect the power

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

Medical interference

Individuals with a ICD must keep an large gap from magnets. The magnetism can interfere with the operation of the implant.

Heat sensitivity

Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.

Phone sensors

Remember: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.

Flammability

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

Hand protection

Big blocks can crush fingers instantly. Never place your hand between two attracting surfaces.

Safe distance

Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.

Choking Hazard

Product intended for adults. Small elements can be swallowed, causing severe trauma. Keep out of reach of kids and pets.

Shattering risk

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Allergy Warning

Some people experience a sensitization to nickel, which is the standard coating for NdFeB magnets. Frequent touching might lead to an allergic reaction. It is best to use safety gloves.
