1. Shear force

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

2. Efficiency vs thickness

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

3. Temperature resistance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.84

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 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 products

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 10x10x10 mm and a weight of 7.5 g, guarantees premium class connection. This rectangular block with a force of 37.71 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.
Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 3.84 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
Plate magnets MPL 10x10x10 / 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 10x10x10 / N38 model is magnetized through the thickness (dimension 10 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. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.
This model is characterized by dimensions 10x10x10 mm, which, at a weight of 7.5 g, makes it an element with high energy density. It is a magnetic block with dimensions 10x10x10 mm and a self-weight of 7.5 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of rare earth magnets.

Pros

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
  • Their strength is maintained, and after approximately ten years it drops only by ~1% (according to research),
  • They possess excellent resistance to magnetic field loss due to external fields,
  • In other words, due to the shiny layer of gold, the element becomes visually attractive,
  • The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
  • Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
  • Possibility of custom machining and optimizing to specific needs,
  • Universal use in modern technologies – they are commonly used in HDD drives, drive modules, medical devices, also industrial machines.
  • Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Weaknesses

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and 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 suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
  • Limited ability of producing threads in the magnet and complex forms - recommended is cover - magnetic holder.
  • Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these devices are able to complicate diagnosis medical after entering the body.
  • Due to complex production process, their price is higher than average,

Holding force characteristics

Maximum holding power of the magnet – what contributes to it?

The specified lifting capacity represents the limit force, recorded under optimal environment, meaning:
  • using a base made of high-permeability steel, functioning as a magnetic yoke
  • possessing a thickness of min. 10 mm to ensure full flux closure
  • characterized by smoothness
  • under conditions of ideal adhesion (metal-to-metal)
  • during pulling in a direction vertical to the plane
  • at standard ambient temperature

Determinants of practical lifting force of a magnet

Real force impacted by working environment parameters, such as (from priority):
  • Clearance – the presence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
  • Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
  • Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
  • Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
  • Thermal environment – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate lowers the holding force.

Safe handling of NdFeB magnets
Impact on smartphones

Be aware: rare earth magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, device, and GPS.

Dust explosion hazard

Powder produced during machining of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Data carriers

Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Bone fractures

Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!

Do not give to children

Adult use only. Small elements can be swallowed, causing serious injuries. Keep away from children and animals.

Magnets are brittle

Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness occurs, immediately stop handling magnets and wear gloves.

Do not underestimate power

Handle with care. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can move away.

Power loss in heat

Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.

Health Danger

People with a ICD should maintain an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.

Danger! Details about hazards in the article: Safety of working with magnets.
