1. Sliding resistance

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

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) significantly limits the holding force.

3. Temperature resistance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.40

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.

Other products

The offered product is an extremely powerful rod magnet, made from durable NdFeB material, which, at dimensions of Ø33x10 mm, guarantees maximum efficiency. This specific item features a tolerance of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 23.67 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is ideal for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 232.15 N with a weight of only 64.15 g, this cylindrical magnet is indispensable in miniature devices 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., 33.1 mm) using two-component epoxy glues. To ensure long-term durability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø33x10), 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 33 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 23.67 kg (force ~232.15 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, 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 33 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.

Pros

Besides their high retention, neodymium magnets are valued for these benefits:
  • They do not lose power, even after approximately ten years – the reduction in power is only ~1% (according to tests),
  • Magnets perfectly resist against loss of magnetization caused by external fields,
  • By covering with a decorative layer of gold, the element acquires an aesthetic look,
  • Magnetic induction on the top side of the magnet turns out to be impressive,
  • 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...
  • Thanks to the ability of free forming and customization to custom requirements, magnetic components can be produced in a variety of shapes and sizes, which increases their versatility,
  • Key role in modern technologies – they are used in mass storage devices, brushless drives, diagnostic systems, and other advanced devices.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Disadvantages

Disadvantages of NdFeB magnets:
  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of making nuts in the magnet and complicated forms - preferred is a housing - mounting mechanism.
  • Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small elements of these devices can complicate diagnosis medical after entering the body.
  • With large orders the cost of neodymium magnets is economically unviable,

Pull force analysis

Best holding force of the magnet in ideal parameterswhat it depends on?

The lifting capacity listed is a measurement result executed under standard conditions:
  • with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
  • with a cross-section no less than 10 mm
  • with a plane cleaned and smooth
  • under conditions of gap-free contact (surface-to-surface)
  • under axial application of breakaway force (90-degree angle)
  • at ambient temperature approx. 20 degrees Celsius

Impact of factors on magnetic holding capacity in practice

Holding efficiency is influenced by working environment parameters, including (from priority):
  • Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
  • Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Material composition – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
  • Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
  • Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Safety rules for work with NdFeB magnets
Conscious usage

Handle magnets with awareness. Their immense force can shock even experienced users. Stay alert and respect their power.

GPS Danger

Remember: rare earth magnets produce a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.

Combustion hazard

Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Warning for heart patients

Individuals with a ICD must keep an absolute distance from magnets. The magnetic field can interfere with the operation of the life-saving device.

Keep away from children

Adult use only. Small elements pose a choking risk, leading to intestinal necrosis. Store out of reach of children and animals.

Crushing risk

Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Use thick gloves.

Magnetic media

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

Heat warning

Avoid heat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).

Risk of cracking

Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.

Metal Allergy

Studies show that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, refrain from direct skin contact or choose encased magnets.
