1. Shear force

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

2. Steel saturation

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

3. Heat tolerance

*For N38 grade, 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.

Other products

This product is an extremely strong 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 block magnet with high power (approx. 1.38 kg), this product is available immediately from our warehouse in Poland. 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. Watch your fingers! Magnets with a force of 1.38 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
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 workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.
For mounting flat magnets MPL 6x6x6 / N38, it is best to use strong epoxy glues (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 roughen and wash 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. In practice, this means that this magnet has the greatest attraction force on its main planes (6x6 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.
This model is characterized by dimensions 6x6x6 mm, which, at a weight of 1.62 g, makes it an element with high energy density. It is a magnetic block with dimensions 6x6x6 mm and a self-weight of 1.62 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros and cons of neodymium magnets.

Benefits

Apart from their superior magnetism, neodymium magnets have these key benefits:
  • They have stable power, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
  • They do not lose their magnetic properties even under close interference source,
  • A magnet with a metallic silver surface is more attractive,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Possibility of individual modeling as well as optimizing to concrete requirements,
  • Huge importance in advanced technology sectors – they are commonly used in data components, motor assemblies, precision medical tools, as well as other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems

Cons

Characteristics of disadvantages of neodymium magnets: application proposals
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • We recommend a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
  • Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical when they are in the body.
  • Due to complex production process, their price exceeds standard values,

Lifting parameters

Maximum lifting capacity of the magnetwhat it depends on?

The declared magnet strength represents the limit force, recorded under ideal test conditions, meaning:
  • on a block made of mild steel, perfectly concentrating the magnetic field
  • with a thickness of at least 10 mm
  • characterized by lack of roughness
  • under conditions of ideal adhesion (metal-to-metal)
  • under perpendicular application of breakaway force (90-degree angle)
  • at standard ambient temperature

What influences lifting capacity in practice

Real force is affected by specific conditions, mainly (from priority):
  • Clearance – the presence of foreign body (paint, dirt, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
  • Base massiveness – too thin sheet does not close the flux, causing part of the power to be escaped into the air.
  • Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
  • Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
  • Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.

Precautions when working with NdFeB magnets
Metal Allergy

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, immediately stop working with magnets and use protective gear.

Magnets are brittle

Neodymium magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them cracking into shards.

Do not underestimate power

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

Flammability

Powder produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Safe distance

Do not bring magnets close to a wallet, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.

Warning for heart patients

Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Do not give to children

These products are not intended for children. Eating several magnets can lead to them pinching intestinal walls, which poses a direct threat to life and requires immediate surgery.

Thermal limits

Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.

GPS and phone interference

Note: neodymium magnets generate a field that confuses precision electronics. Keep a separation from your mobile, tablet, and GPS.

Hand protection

Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
