1. Vertical hold

*Note: On a vertical wall, the magnet retains only ~20% of its max power.

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.

Other deals

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 magnetic bar 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.
Separating strong flat 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 1.38 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.
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.
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).
The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. 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 impressive 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.

Pros

Apart from their notable magnetic energy, neodymium magnets have these key benefits:
  • They retain magnetic properties for nearly ten years – the drop is just ~1% (based on simulations),
  • Neodymium magnets are exceptionally resistant to magnetic field loss caused by external interference,
  • A magnet with a metallic silver surface is more attractive,
  • Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
  • 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 detailed forming and adapting to individual needs,
  • Fundamental importance in high-tech industry – they are used in hard drives, brushless drives, precision medical tools, and modern systems.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:
  • To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
  • Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of producing threads in the magnet and complex forms - preferred is a housing - magnet mounting.
  • Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets can be problematic in diagnostics medical after entering the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Maximum lifting force for a neodymium magnet – what affects it?

The lifting capacity listed is a measurement result performed under standard conditions:
  • using a sheet made of low-carbon steel, acting as a magnetic yoke
  • whose thickness is min. 10 mm
  • with an ideally smooth touching surface
  • without the slightest insulating layer between the magnet and steel
  • during pulling in a direction perpendicular to the plane
  • at conditions approx. 20°C

Lifting capacity in real conditions – factors

In real-world applications, the actual lifting capacity is determined by many variables, presented from the most important:
  • Clearance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of maximum force).
  • Steel thickness – too thin plate does not close the flux, causing part of the flux to be escaped to the other side.
  • Chemical composition of the base – low-carbon steel attracts best. Alloy steels reduce magnetic properties and lifting capacity.
  • Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
  • Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets
Bone fractures

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

Allergic reactions

It is widely known that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or select coated magnets.

Data carriers

Do not bring magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.

Power loss in heat

Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

GPS and phone interference

A powerful magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a device to avoid damaging the sensors.

Eye protection

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into shards.

Life threat

Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.

Danger to the youngest

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

Caution required

Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Flammability

Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.

Caution! Details about hazards in the article: Magnet Safety Guide.
