Grip strength drops drastically with every subsequent millimeter of gap. Keep in mind that even the smallest gap (e.g., dirt, paint, dust) noticeably reduces the pull force. Neodymiums hold most effectively in perfect adhesion; air break drastically cuts the force. Observe how rapidly the load capacity fall, when the magnet does not adhere tightly to the steel surface. When calculating the arrangement, eliminate redundant distances.

When hanging a holder on a upright plane (e.g., a car body), it you can count on barely approx. 1/5 of its nominal power. Gravity and a low friction coefficient mean that magnets move down faster than they pop off the substrate. Planning a vertical fastening? Note that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the magnet will slip down under a much lighter weight. Using a rubber coating can drastically raise the stability.

A too thin steel is incapable of conduct the full magnetic flux, which wastes potential of the magnet. Should you install a neodymium to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To squeeze full efficiency of this neodymium's power, you need a suitably thick piece of metal. The saturation phenomenon means that on delicate walls (e.g., thin profiles), the magnet shows lower pull force. We advise picking the steel cross-section from these parameters.

Standard neodymium magnets irreversibly lose power above the temperature limit. Watch out for overheating – excessive heat can irreversibly demagnetize this magnet. With increasing heat, the neodymium's power momentarily decreases. Avoid using this product close to heaters higher than its operating temperature limit. Exceeding the critical threshold will cause destruction of magnetic properties.
*Engineering note: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) are more susceptible to demagnetization at lower temperatures than taller cylinders. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Designing a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the impact force is massive. The repulsion force is marginally weaker than the attraction, but still large.
*Field value between like poles drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Note: Calculations show friction force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a serious hazard to electronic devices as well as medical implants. These NdFeB products produce a field that disrupts operation of digital equipment. Notice: the invisible magnetic field penetrates the body and plastic. Special caution must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a strong collision with metal can result in shattering. Control the attraction moment – a neodymium left loose turns into a projectile. Impact energy can trigger coating fragments or injury to fingers. Always hold the magnet during mounting so it doesn't slam with momentum against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

1. Vertical hold

*Caution: On a vertical wall, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

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

3. Temperature resistance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.45

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 cylinder magnet, composed of advanced NdFeB material, which, with dimensions of Ø29x10 mm, guarantees maximum efficiency. This specific item features an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 20.82 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 204.22 N with a weight of only 49.54 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
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., 29.1 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 high repeatability of the connection.
Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø29x10), 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 Ø29x10 mm, which, at a weight of 49.54 g, makes it an element with high magnetic energy density. The value of 204.22 N means that the magnet is capable of holding a weight many times exceeding its own mass of 49.54 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 29 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 and weaknesses of rare earth magnets.

Strengths

Apart from their strong magnetic energy, neodymium magnets have these key benefits:
  • They retain magnetic properties for almost 10 years – the loss is just ~1% (based on simulations),
  • They are extremely resistant to demagnetization induced by external disturbances,
  • The use of an refined coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
  • The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • In view of the option of precise molding and adaptation to unique projects, NdFeB magnets can be manufactured in a wide range of forms and dimensions, which makes them more universal,
  • Versatile presence in innovative solutions – they are commonly used in mass storage devices, drive modules, medical devices, and complex engineering applications.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Disadvantages of NdFeB 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 demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Due to limitations in creating threads and complex shapes in magnets, we propose using a housing - magnetic mechanism.
  • Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Additionally, small elements of these magnets are able to complicate diagnosis medical when they are in the body.
  • With large orders the cost of neodymium magnets can be a barrier,

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

Breakaway force was determined for optimal configuration, taking into account:
  • with the application of a sheet made of special test steel, ensuring full magnetic saturation
  • possessing a massiveness of min. 10 mm to ensure full flux closure
  • with a plane perfectly flat
  • under conditions of gap-free contact (metal-to-metal)
  • under vertical application of breakaway force (90-degree angle)
  • at temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

During everyday use, the real power results from a number of factors, presented from crucial:
  • Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
  • Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
  • Plate texture – ground elements ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
  • Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with neodymium magnets
Caution required

Use magnets consciously. Their huge power can surprise even professionals. Stay alert and respect their force.

Sensitization to coating

Studies show that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands or select encased magnets.

Magnet fragility

Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.

Phone sensors

Be aware: neodymium magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.

Electronic devices

Powerful magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.

Warning for heart patients

Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Serious injuries

Large magnets can break fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.

Flammability

Machining of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Maximum temperature

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Adults only

These products are not suitable for play. Swallowing a few magnets can lead to them attracting across intestines, which constitutes a severe health hazard and requires urgent medical intervention.
