1. Wall mount (shear)

*Note: On a vertical surface, the magnet retains merely ~20% of its nominal pull.

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Power loss vs temp

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

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

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

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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.

The presented product is an incredibly powerful rod magnet, composed of advanced NdFeB material, which, with dimensions of Ø6x1 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.35 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
This model is ideal for building generators, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 3.41 N with a weight of only 0.21 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 6.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Magnets N38 are suitable for 90% 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 warehouse.
This model is characterized by dimensions Ø6x1 mm, which, at a weight of 0.21 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 0.35 kg (force ~3.41 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 1 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard 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.

Strengths and weaknesses of neodymium magnets.

Pros

Besides their stability, neodymium magnets are valued for these benefits:
  • Their power is maintained, and after around 10 years it decreases only by ~1% (according to research),
  • Magnets perfectly resist against loss of magnetization caused by ambient magnetic noise,
  • Thanks to the glossy finish, the coating of nickel, gold, or silver gives an elegant appearance,
  • Neodymium magnets create maximum magnetic induction on a contact point, which ensures high operational effectiveness,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to the ability of accurate molding and customization to unique solutions, magnetic components can be created in a wide range of forms and dimensions, which expands the range of possible applications,
  • Fundamental importance in modern technologies – they are used in hard drives, electromotive mechanisms, precision medical tools, also industrial machines.
  • Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Limitations

Problematic aspects of neodymium magnets: weaknesses and usage proposals
  • They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
  • Limited ability of creating nuts in the magnet and complex forms - recommended is casing - mounting mechanism.
  • Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products can be problematic in diagnostics medical when they are in the body.
  • With mass production the cost of neodymium magnets is a challenge,

Holding force characteristics

Maximum lifting capacity of the magnetwhat contributes to it?

Information about lifting capacity was determined for the most favorable conditions, assuming:
  • on a block made of structural steel, optimally conducting the magnetic field
  • with a cross-section of at least 10 mm
  • with an ideally smooth touching surface
  • without any insulating layer between the magnet and steel
  • during detachment in a direction vertical to the plane
  • at temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

It is worth knowing that the magnet holding may be lower depending on the following factors, starting with the most relevant:
  • Clearance – the presence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
  • Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
  • Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was determined by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet and the plate reduces the load capacity.

H&S for magnets
Precision electronics

An intense magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets near a device to avoid damaging the sensors.

Safe operation

Be careful. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can move away.

Flammability

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

Crushing force

Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Operating temperature

Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.

Metal Allergy

Certain individuals experience a hypersensitivity to nickel, which is the common plating for neodymium magnets. Frequent touching can result in skin redness. It is best to wear safety gloves.

Eye protection

Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.

Swallowing risk

Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store away from kids and pets.

Safe distance

Powerful magnetic fields can destroy records on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.

Medical interference

Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
