1. Shear force

*Warning: On a vertical wall, the magnet holds merely a fraction of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) drastically limits the holding force.

3. Temperature resistance

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

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

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

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.

Other proposals

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 6x6x6 mm and a weight of 1.62 g, guarantees the highest quality connection. As a magnetic bar with high power (approx. 1.38 kg), this product is available off-the-shelf from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.
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 6x6x6 / 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. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.
Plate magnets MPL 6x6x6 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.
For mounting flat magnets MPL 6x6x6 / N38, it is best to use two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. 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 6x6x6 / N38 model is magnetized through the thickness (dimension 6 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.
The presented product is a neodymium magnet with precisely defined parameters: 6 mm (length), 6 mm (width), and 6 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 1.38 kg (force ~13.54 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of Nd2Fe14B magnets.

Benefits

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
  • Their magnetic field is durable, and after approximately ten years it drops only by ~1% (theoretically),
  • They possess excellent resistance to weakening of magnetic properties as a result of external fields,
  • A magnet with a shiny silver surface has better aesthetics,
  • They are known for high magnetic induction at the operating surface, which improves attraction properties,
  • Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
  • Possibility of individual shaping as well as optimizing to concrete conditions,
  • Fundamental importance in future technologies – they are used in hard drives, brushless drives, diagnostic systems, also other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems

Disadvantages

Disadvantages of NdFeB magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
  • NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and 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
  • They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of producing threads in the magnet and complicated forms - preferred is a housing - mounting mechanism.
  • Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets are able to complicate diagnosis medical when they are in the body.
  • Due to neodymium price, their price exceeds standard values,

Pull force analysis

Highest magnetic holding forcewhat affects it?

Magnet power is the result of a measurement for ideal contact conditions, assuming:
  • with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
  • possessing a massiveness of minimum 10 mm to ensure full flux closure
  • with an ground touching surface
  • under conditions of ideal adhesion (metal-to-metal)
  • under axial force direction (90-degree angle)
  • at standard ambient temperature

Lifting capacity in real conditions – factors

In practice, the actual holding force is determined by several key aspects, listed from the most important:
  • Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
  • Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
  • Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
  • Plate material – low-carbon steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
  • Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
  • Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of neodymium magnets
Electronic hazard

Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Nickel coating and allergies

Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness happens, immediately stop working with magnets and wear gloves.

Warning for heart patients

People with a pacemaker should maintain an safe separation from magnets. The magnetism can disrupt the operation of the implant.

Demagnetization risk

Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. This process is irreversible.

Conscious usage

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

GPS Danger

An intense magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Keep magnets close to a smartphone to prevent damaging the sensors.

Finger safety

Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.

Keep away from children

Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Store away from kids and pets.

Flammability

Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Risk of cracking

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets will cause them shattering into shards.
