1. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains just ~20% of its perpendicular strength.

2. Steel thickness impact

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

3. Heat tolerance

*For N38 grade, 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.

Other products

The offered product is an extremely powerful cylindrical magnet, composed of durable NdFeB material, which, with dimensions of Ø10x6 mm, guarantees the highest energy density. This specific item features a tolerance of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 3.38 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is ideal for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration 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 miniature devices and wherever every gram matters.
Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using two-component epoxy glues. To ensure stability 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 90% of applications in modeling and machine building, where extreme 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 warehouse.
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 secures it 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. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized through the diameter if your project requires it.

Strengths as well as weaknesses of neodymium magnets.

Pros

Besides their exceptional field intensity, neodymium magnets offer the following advantages:
  • They do not lose power, even after around ten years – the reduction in power is only ~1% (theoretically),
  • They have excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
  • A magnet with a smooth silver surface has an effective appearance,
  • Neodymium magnets generate maximum magnetic induction on a small surface, which ensures high operational effectiveness,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • In view of the potential of precise molding and customization to individualized solutions, magnetic components can be produced in a variety of geometric configurations, which amplifies use scope,
  • Huge importance in innovative solutions – they are utilized in hard drives, electric motors, medical devices, and multitasking production systems.
  • Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Limitations

Characteristics of disadvantages of neodymium magnets and proposals for their use:
  • They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
  • When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and 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 immune to moisture, when using outdoors
  • We suggest a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated forms.
  • Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Detachment force of the magnet in optimal conditionswhat affects it?

The declared magnet strength refers to the limit force, recorded under laboratory conditions, meaning:
  • on a block made of structural steel, optimally conducting the magnetic flux
  • possessing a thickness of min. 10 mm to avoid saturation
  • with an polished touching surface
  • with zero gap (no paint)
  • for force applied at a right angle (pull-off, not shear)
  • at standard ambient temperature

Magnet lifting force in use – key factors

During everyday use, the real power results from many variables, presented from most significant:
  • Gap (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
  • Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
  • Metal type – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
  • Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal environment – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with neodymium magnets
Bodily injuries

Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Pacemakers

Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Warning for allergy sufferers

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, immediately stop working with magnets and use protective gear.

Dust is flammable

Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Keep away from electronics

Remember: neodymium magnets produce a field that confuses sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.

Magnets are brittle

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

Safe distance

Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Do not underestimate power

Handle with care. Rare earth magnets act from a distance and connect with huge force, often faster than you can move away.

Choking Hazard

Always store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are life-threatening.

Operating temperature

Keep cool. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
