1. Shear force

*Caution: On a vertical surface, the magnet retains only approx. 20-30% of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely reduces the holding force.

3. Power loss vs temp

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.44

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.

Field Strength

Other products

This product is an incredibly powerful rod magnet, composed of advanced NdFeB material, which, at dimensions of Ø6x2 mm, guarantees maximum efficiency. The MW 6x2 / N38 model boasts an accuracy of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.86 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 8.43 N with a weight of only 0.42 g, this rod is indispensable in electronics and wherever low weight is crucial.
Due to the delicate structure of the ceramic sinter, 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 do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Magnets N38 are suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø6x2), 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 Ø6x2 mm, which, at a weight of 0.42 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 0.86 kg (force ~8.43 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 2 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 diametrically if your project requires it.

Pros and cons of neodymium magnets.

Benefits

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
  • They retain full power for around ten years – the drop is just ~1% (in theory),
  • Magnets perfectly resist against demagnetization caused by external fields,
  • Thanks to the glossy finish, the plating of nickel, gold, or silver-plated gives an clean appearance,
  • Magnets have extremely high magnetic induction on the surface,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • Possibility of custom forming and adapting to defined needs,
  • Universal use in high-tech industry – they are utilized in data components, motor assemblies, advanced medical instruments, as well as industrial machines.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Weaknesses

Characteristics of disadvantages of neodymium magnets: application proposals
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
  • Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Limited ability of making threads in the magnet and complex shapes - preferred is casing - magnetic holder.
  • Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
  • With large orders the cost of neodymium magnets is a challenge,

Lifting parameters

Highest magnetic holding forcewhat affects it?

The force parameter is a measurement result performed under the following configuration:
  • using a sheet made of low-carbon steel, serving as a circuit closing element
  • with a thickness minimum 10 mm
  • with a surface cleaned and smooth
  • without the slightest insulating layer between the magnet and steel
  • during pulling in a direction perpendicular to the mounting surface
  • at ambient temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

During everyday use, the real power is determined by many variables, ranked from the most important:
  • Distance – existence of any layer (paint, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
  • Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
  • Surface finish – ideal contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
  • Temperature influence – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

H&S for magnets
Hand protection

Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Beware of splinters

Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Health Danger

People with a ICD have to maintain an absolute distance from magnets. The magnetic field can disrupt the functioning of the implant.

Keep away from computers

Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.

Do not overheat magnets

Avoid heat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Fire risk

Dust produced during machining of magnets is flammable. Do not drill into magnets unless you are an expert.

Caution required

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

GPS Danger

GPS units and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.

This is not a toy

Strictly store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are very dangerous.

Warning for allergy sufferers

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop working with magnets and wear gloves.

Danger! Learn more about risks in the article: Safety of working with magnets.
