1. Wall mount (shear)

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

2. Efficiency vs thickness

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.25

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.

Magnetic Induction

Other offers

This product is an extremely powerful rod magnet, produced from advanced NdFeB material, which, at dimensions of Ø6x1 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 0.35 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is ideal for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 3.41 N with a weight of only 0.21 g, this rod is indispensable in electronics and wherever low weight is crucial.
Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Magnets NdFeB grade N38 are strong enough for the majority of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø6x1), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 6 mm and height 1 mm. The value of 3.41 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.21 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, 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 6 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 Nd2Fe14B magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:
  • They retain magnetic properties for nearly ten years – the drop is just ~1% (in theory),
  • They possess excellent resistance to magnetic field loss as a result of external magnetic sources,
  • By covering with a decorative layer of silver, the element gains an aesthetic look,
  • The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Thanks to the ability of free molding and customization to custom needs, magnetic components can be produced in a wide range of forms and dimensions, which expands the range of possible applications,
  • Fundamental importance in innovative solutions – they are commonly used in HDD drives, motor assemblies, medical devices, and technologically advanced constructions.
  • Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Limitations

Drawbacks and weaknesses of neodymium magnets and proposals for their use:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of creating nuts in the magnet and complex shapes - recommended is casing - mounting mechanism.
  • Health risk related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small components of these products can complicate diagnosis medical when they are in the body.
  • With large orders the cost of neodymium magnets can be a barrier,

Holding force characteristics

Maximum magnetic pulling forcewhat affects it?

The lifting capacity listed is a theoretical maximum value conducted under specific, ideal conditions:
  • with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
  • possessing a massiveness of minimum 10 mm to ensure full flux closure
  • with a plane perfectly flat
  • without any insulating layer between the magnet and steel
  • for force acting at a right angle (in the magnet axis)
  • at ambient temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

Holding efficiency impacted by working environment parameters, such as (from most important):
  • Gap between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
  • Load vector – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
  • Material type – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
  • Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
  • Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

H&S for magnets
Bodily injuries

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

Pacemakers

Patients with a pacemaker should keep an safe separation from magnets. The magnetic field can interfere with the functioning of the life-saving device.

Fragile material

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Magnetic interference

A powerful magnetic field disrupts the operation of compasses in phones and GPS navigation. Do not bring magnets close to a device to prevent breaking the sensors.

Dust explosion hazard

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

Electronic hazard

Avoid bringing magnets close to a purse, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.

Power loss in heat

Watch the temperature. Heating the magnet to high heat will ruin its magnetic structure and strength.

Adults only

Always keep magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are life-threatening.

Nickel allergy

Medical facts indicate that the nickel plating (the usual finish) is a common allergen. If you have an allergy, prevent direct skin contact and choose versions in plastic housing.

Powerful field

Use magnets with awareness. Their huge power can surprise even experienced users. Be vigilant and respect their power.
