Pulling power decreases sharply per each millimeter of spacing. Keep in mind that even a microscopic distance (e.g., contamination, paint, dust) significantly diminishes the holding power. Neodymiums hold optimally in perfect adhesion; air break weakens the power. Analyze how rapidly the load capacity drop, when the product does not adhere flatly to the steel surface. When planning the assembly, avoid additional spacers.

This section calculates the approximate force sufficient to cause the slippage of the magnet down on a upright steel plate (assuming typical friction coefficient). The holding force is a function of the air gap between the magnet and the surface.

When mounting a holder on a vertical wall (e.g., a board), it will only hold only about 1/5 of its nominal power. Gravity and a weak degree of grip influence the fact that holders slip easier than they detach. Designing a hanger? Note that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the magnet will slip down under a significantly smaller cargo. Application of an anti-slip layer can significantly raise the stability.

A too thin steel is not enough to conduct the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a thin surface, the field will pass right through and the attraction force will be weaker. To utilize 100% of this magnet's power, you require a sufficiently solid backing of metal. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the holder works worse. We suggest choosing the steel dimension from these parameters.

Classic neodymiums lose parameters above the temperature limit. Watch out for overheating – high temperature can permanently demagnetize this magnet. With increasing heat, the neodymium's capacity briefly lowers. Do not use this product close to heaters higher than its working range. Ignoring the limit will result in permanent loss of magnetism.

*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) risk losing magnetic properties at lower temperatures compared to rod magnets. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a wider radius than a magnet and steel combination. Such a system of two magnets creates a more powerful interaction and a larger range of action. Want to build a solid fastener? Use a pair of magnets instead of one magnet and a steel. Remember that when attracting two neodymiums, the pinch force is extreme. The repulsion force is slightly lower than the attraction, but still large.
*Flux density for N-N configuration reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Attention: Estimates demonstrate sliding force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a serious hazard to electronic devices as well as medical implants. These magnets generate a field that disrupts operation of digital equipment. Remember: the invisible magnetic field penetrates the body and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can destroy the magnet or injury to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the magnet. Wear eye protection when handling with powerful specimens.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Note: On a vertical surface, the magnet holds merely a fraction of its nominal pull.

2. Steel thickness impact

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

3. Thermal stability

*For N38 grade, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.39

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 P_c (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 P_c 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 extremely powerful cylindrical magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø70x20 mm, guarantees maximum efficiency. The MW 70x20 / N38 model features a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 99.83 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in typical 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 979.31 N with a weight of only 577.27 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø70x20), 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 Ø70x20 mm, which, at a weight of 577.27 g, makes it an element with high magnetic energy density. The value of 979.31 N means that the magnet is capable of holding a weight many times exceeding its own mass of 577.27 g. The product has a [NiCuNi] coating, which secures it 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 70 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 diametrically if your project requires it.

Pros and cons of Nd₂Fe₁₄B magnets.

Advantages

Besides their high retention, neodymium magnets are valued for these benefits:

They do not lose strength, even over nearly 10 years – the reduction in power is only ~1% (based on measurements),
They possess excellent resistance to magnetic field loss as a result of external fields,
A magnet with a smooth gold surface has an effective appearance,
Magnets have huge magnetic induction on the outer layer,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
Possibility of exact machining and adjusting to individual conditions,
Universal use in innovative solutions – they are commonly used in HDD drives, electric motors, medical equipment, and other advanced devices.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of NdFeB magnets:

At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's 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 rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing threads and complex forms in magnets, we propose using a housing - magnetic holder.
Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Breakaway strength of the magnet in ideal conditions – what contributes to it?

Breakaway force was defined for the most favorable conditions, assuming:

with the contact of a yoke made of low-carbon steel, ensuring maximum field concentration
whose thickness reaches at least 10 mm
with a plane cleaned and smooth
with total lack of distance (no coatings)
during pulling in a direction perpendicular to the mounting surface
in stable room temperature

Determinants of practical lifting force of a magnet

In practice, the actual holding force depends on a number of factors, presented from most significant:

Distance (betwixt the magnet and the plate), because even a very small distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
Base massiveness – too thin sheet does not close the flux, causing part of the power to be wasted into the air.
Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity was measured by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.

Warnings

Cards and drives

Avoid bringing magnets close to a wallet, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.

GPS Danger

A strong magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to prevent breaking the sensors.

Crushing risk

Risk of injury: The pulling power is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.

Caution required

Handle magnets consciously. Their powerful strength can shock even experienced users. Be vigilant and respect their power.

Permanent damage

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

Warning for heart patients

Individuals with a pacemaker must maintain an absolute distance from magnets. The magnetism can interfere with the operation of the life-saving device.

Nickel coating and allergies

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands or opt for versions in plastic housing.

Dust explosion hazard

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

Protective goggles

NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them breaking into shards.

Product not for children

Neodymium magnets are not suitable for play. Swallowing multiple magnets may result in them attracting across intestines, which constitutes a critical condition and necessitates immediate surgery.
