1. Shear force

*Warning: On a vertical surface, the magnet holds merely ~20% of its max power.

2. Steel saturation

*Thin metal sheet (e.g. computer case) drastically limits 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) = 0.22

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 offers

This product is an exceptionally strong rod magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø10x1.5 mm, guarantees optimal power. This specific item boasts an accuracy of ±0.1mm and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.82 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 8.01 N with a weight of only 0.88 g, this rod is indispensable in electronics and wherever every gram matters.
Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using epoxy glues. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø10x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
This model is characterized by dimensions Ø10x1.5 mm, which, at a weight of 0.88 g, makes it an element with impressive magnetic energy density. The value of 8.01 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.88 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 10 mm. 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 rare earth magnets.

Benefits

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
  • They possess excellent resistance to magnetic field loss when exposed to external fields,
  • In other words, due to the smooth finish of silver, the element gains a professional look,
  • 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...
  • In view of the potential of accurate molding and customization to unique projects, NdFeB magnets can be manufactured in a variety of shapes and sizes, which expands the range of possible applications,
  • Fundamental importance in high-tech industry – they are used in hard drives, electric motors, precision medical tools, also industrial machines.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions

Limitations

Disadvantages of neodymium magnets:
  • To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • Neodymium magnets decrease their force 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 durability even at temperatures up to 230°C
  • Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • Due to limitations in realizing threads and complicated forms in magnets, we recommend using a housing - magnetic mount.
  • Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these devices can disrupt the diagnostic process medical after entering the body.
  • Due to expensive raw materials, their price is higher than average,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what it depends on?

The load parameter shown represents the peak performance, obtained under laboratory conditions, namely:
  • on a block made of mild steel, perfectly concentrating the magnetic flux
  • possessing a thickness of min. 10 mm to avoid saturation
  • with a surface free of scratches
  • with zero gap (without impurities)
  • during detachment in a direction perpendicular to the plane
  • in stable room temperature

Lifting capacity in practice – influencing factors

In practice, the real power is determined by many variables, presented from crucial:
  • Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
  • Load vector – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Material type – ideal substrate is pure iron steel. Cast iron may attract less.
  • Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
  • Thermal environment – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

H&S for magnets
Protective goggles

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

Warning for allergy sufferers

Studies show that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, avoid direct skin contact and opt for versions in plastic housing.

Thermal limits

Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.

Bone fractures

Big blocks can smash fingers in a fraction of a second. Never put your hand between two attracting surfaces.

Product not for children

Strictly keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are very dangerous.

Fire risk

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

Threat to navigation

Be aware: neodymium magnets produce a field that confuses sensitive sensors. Maintain a separation from your mobile, device, and GPS.

Life threat

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

Protect data

Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Conscious usage

Before starting, read the rules. Sudden snapping can break the magnet or injure your hand. Think ahead.
