Magnetic force weakens significantly per each millimeter of distance. Remember that even a microscopic distance (e.g., dirt, paint, rust) significantly reduces the pull force. Magnetic products operate optimally in perfect adhesion; gap weakens the power. Observe how quickly the pull force drop, when the product does not adhere flatly to the steel surface. When designing the mounting, eliminate unnecessary gaps.

This section indicates the theoretical weight limit sufficient to start the slippage of the magnet down against a vertical metal surface (assuming typical friction coefficient). The holding force varies with the distance between the magnet and the surface.

When hanging a holder on a upright plane (e.g., a fridge), it will only hold only approx. 20%-30% of its maximum pull force. Gravitational force as well as a weak degree of grip cause that products slip easier than they detach. Planning a hanger? Remember that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the element will slip down under a much lighter load. Application of an anti-slip pad can significantly raise the stability.

A too thin steel is not enough to focus the full magnetic flux, which squanders power of the magnet. Should you mount a strong magnet to a too thin substrate, the magnetism will penetrate right through and the pull force will drop sharply. To utilize 100% of this neodymium's power, you require a sufficiently solid backing of metal. The saturation effect means that on delicate walls (e.g., thin profiles), the magnet holds weaker. We suggest choosing the steel thickness according to the table below.

Classic neodymiums irreversibly lose strength above the temperature limit. Watch out for overheating – excessive heat can irreversibly demagnetize this product. With increasing heat, the magnet's capacity temporarily drops. Refrain from using this magnet close to ovens higher than its working range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization sooner than long magnets. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a neodymium and metal combination. Such a system of two magnets produces a massive flux and a larger range of operation. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the pinch force is huge. The repulsion force is slightly lower than the connection force, but still impressive.
*Flux density in repulsion mode drops to ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Results demonstrate shear force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field is a real danger to IT equipment and medical implants. These magnets produce a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and plastic. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can cause material chips or painful pinches to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when playing with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Wall mount (shear)

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

2. Efficiency vs thickness

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

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.12

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 rod magnet, composed of durable NdFeB material, which, with dimensions of Ø20x1.5 mm, guarantees maximum efficiency. This specific item boasts a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 0.97 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 9.50 N with a weight of only 3.53 g, this cylindrical magnet is indispensable in electronics 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., 20.1 mm) using epoxy glues. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets N38 are suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø20x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 20 mm and height 1.5 mm. The key parameter here is the lifting capacity amounting to approximately 0.97 kg (force ~9.50 N), which, with such compact dimensions, proves the high grade of the NdFeB material. 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 20 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 diametrically if your project requires it.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Strengths

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

They do not lose strength, even over around 10 years – the drop in power is only ~1% (based on measurements),
They are noted for resistance to demagnetization induced by external field influence,
The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnetic induction on the surface of the magnet is impressive,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
Thanks to the option of precise forming and customization to unique needs, NdFeB magnets can be modeled in a broad palette of forms and dimensions, which expands the range of possible applications,
Huge importance in modern technologies – they find application in hard drives, electromotive mechanisms, precision medical tools, as well as industrial machines.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
We recommend casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated forms.
Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
With large orders the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum holding power of the magnet – what it depends on?

Magnet power was defined for ideal contact conditions, taking into account:

with the use of a sheet made of special test steel, ensuring maximum field concentration
whose transverse dimension equals approx. 10 mm
with an polished touching surface
without any air gap between the magnet and steel
for force acting at a right angle (in the magnet axis)
in stable room temperature

What influences lifting capacity in practice

In practice, the actual lifting capacity is determined by a number of factors, ranked from crucial:

Gap (betwixt the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

Safe handling of neodymium magnets

Swallowing risk

Adult use only. Tiny parts pose a choking risk, causing serious injuries. Keep away from kids and pets.

Finger safety

Pinching hazard: The attraction force is so great that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Immense force

Be careful. Neodymium magnets act from a long distance and connect with huge force, often faster than you can move away.

Precision electronics

A strong magnetic field disrupts the functioning of compasses in phones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.

Allergy Warning

Some people experience a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Frequent touching might lead to an allergic reaction. We suggest use protective gloves.

Permanent damage

Avoid heat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).

Risk of cracking

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets will cause them shattering into small pieces.

Data carriers

Data protection: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, mechanical watches).

Implant safety

For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.

Dust explosion hazard

Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.

Attention! More info about hazards in the article: Safety of working with magnets.
