1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains just approx. 20-30% of its max power.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) significantly limits the holding force.

3. Temperature resistance

*For N38 material, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.66

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.

Magnet pull force


Magnetic Induction

Other proposals

The offered product is an exceptionally strong cylinder magnet, manufactured from modern NdFeB material, which, with dimensions of Ø10x6 mm, guarantees maximum efficiency. This specific item features high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 3.38 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is created for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 33.12 N with a weight of only 3.53 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Magnets NdFeB grade N38 are strong enough for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø10x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 6 mm. The value of 33.12 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.53 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 10 mm. Such an arrangement is most desirable when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized through the diameter if your project requires it.

Pros and cons of rare earth magnets.

Benefits

Apart from their notable holding force, neodymium magnets have these key benefits:
  • They have stable power, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
  • Neodymium magnets are characterized by extremely resistant to demagnetization caused by external interference,
  • In other words, due to the aesthetic surface of nickel, the element becomes visually attractive,
  • The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to the option of free forming and customization to individualized solutions, magnetic components can be modeled in a broad palette of geometric configurations, which makes them more universal,
  • Wide application in modern industrial fields – they serve a role in magnetic memories, electric drive systems, diagnostic systems, also modern systems.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Weaknesses

Disadvantages of neodymium magnets:
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
  • NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
  • Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • Limited possibility of producing nuts in the magnet and complex shapes - preferred is a housing - magnetic holder.
  • Health risk to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small components of these products can disrupt the diagnostic process medical when they are in the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Optimal lifting capacity of a neodymium magnetwhat contributes to it?

The load parameter shown represents the peak performance, recorded under ideal test conditions, specifically:
  • using a sheet made of low-carbon steel, serving as a ideal flux conductor
  • whose thickness equals approx. 10 mm
  • with an ground contact surface
  • with total lack of distance (without impurities)
  • during detachment in a direction perpendicular to the plane
  • in temp. approx. 20°C

Practical aspects of lifting capacity – factors

Bear in mind that the magnet holding may be lower depending on elements below, starting with the most relevant:
  • Distance – existence of any layer (rust, dirt, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
  • Plate thickness – insufficiently thick sheet does not close the flux, causing part of the flux to be escaped to the other side.
  • Material type – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
  • Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
  • Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.

Safe handling of neodymium magnets
Danger to pacemakers

Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Swallowing risk

Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.

Crushing force

Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.

Magnetic interference

Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.

Nickel allergy

Some people experience a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Extended handling may cause an allergic reaction. We strongly advise wear protective gloves.

Risk of cracking

Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Keep away from computers

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

Machining danger

Drilling and cutting of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Conscious usage

Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their power.

Heat sensitivity

Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.

Caution! Details about risks in the article: Safety of working with magnets.
