Magnetic force weakens drastically with every subsequent millimeter of distance. Remember that every additional insulation layer (e.g., contamination, paint, rust) noticeably diminishes the holding power. Magnetic products work strongest at the point of direct contact; air break kills the power. Analyze how quickly the parameters drop, when the product does not touch flatly to the steel surface. When calculating the assembly, eliminate additional spacers.

The table below presents the estimated weight limit required to start the shifting of the magnet downwards along a upright steel plate (assuming standard friction). This parameter is relative to the separation distance between the magnet and the metal.

When hanging a magnet on a vertical wall (e.g., a fridge), it will maintain just about 1/5 of its nominal power. Gravitational force and a weak degree of grip influence the fact that holders slide down easier than they pop off the substrate. Planning a vertical fastening? Consider that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the element will slide down under a significantly smaller load. Utilizing a rubberized coating can effectively increase the grip.

A thin metal plate is not enough to take in the entire magnetic field, which wastes potential of the magnet. Should you install a neodymium to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To achieve 100% of this magnet's power, you need a suitably thick element of steel. The saturation effect means that on sheet metal structures (e.g., car bodies), the magnet works worse. We suggest choosing the steel dimension based on the following data.

Ordinary NdFeB products irreversibly lose power past the thermal threshold. Avoid high temperatures – heat can irreversibly destroy this magnet. As the temperature rises, the neodymium's capacity temporarily lowers. Do not use this product near heat sources exceeding its safe range. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) are more susceptible to demagnetization under lower heat stress than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products interact from a significantly greater distance than a neodymium and metal combination. The connection of magnet-to-magnet produces a massive flux and a wider radius of action. Designing a powerful holder? Apply two magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the collision energy is huge. The repulsion force is marginally weaker than the attraction, but still significant.
*Field value in repulsion mode drops to ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Important: Figures apply to friction force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a large risk to electronic devices and medical implants. These NdFeB products produce a flux that disrupts operation of digital equipment. Remember: the invisible magnetic field passes through tissues and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely turns into a projectile. Impact energy can cause material chips or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the neodymium. Wear safety glasses when working 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. Sliding resistance

*Caution: On a vertical wall, the magnet holds only a fraction of its nominal pull.

2. Steel saturation

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

3. Thermal stability

*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) = 1.55

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 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 offered product is an incredibly powerful cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø5x25 mm, guarantees the highest energy density. The MW 5x25 / N38 model is characterized by an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.45 kg), this product is available off-the-shelf from our European logistics center, ensuring quick 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 created for building generators, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 4.41 N with a weight of only 3.68 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are strong enough for the majority 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 (Ø5x25), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 5 mm and height 25 mm. The key parameter here is the holding force amounting to approximately 0.45 kg (force ~4.41 N), which, with such compact dimensions, proves the high power 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 5 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.

Strengths as well as weaknesses of rare earth magnets.

Pros

Besides their remarkable pulling force, neodymium magnets offer the following advantages:

They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
Neodymium magnets are distinguished by highly resistant to demagnetization caused by magnetic disturbances,
By covering with a decorative coating of gold, the element gains an nice look,
Magnetic induction on the top side of the magnet turns out to be exceptional,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of exact forming and adjusting to precise conditions,
Key role in advanced technology sectors – they find application in computer drives, brushless drives, diagnostic systems, and modern systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
We suggest cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated shapes.
Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these magnets can be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Highest magnetic holding force – what it depends on?

The force parameter is a measurement result performed under specific, ideal conditions:

using a plate made of high-permeability steel, serving as a circuit closing element
with a cross-section no less than 10 mm
with a plane cleaned and smooth
under conditions of ideal adhesion (metal-to-metal)
during detachment in a direction perpendicular to the plane
at room temperature

Determinants of lifting force in real conditions

Effective lifting capacity is influenced by specific conditions, including (from priority):

Air gap (between the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Load vector – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
Steel type – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
Thermal environment – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.

Warnings

Operating temperature

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

Keep away from children

Adult use only. Tiny parts can be swallowed, causing intestinal necrosis. Store away from children and animals.

Crushing risk

Danger of trauma: The attraction force is so great that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.

Powerful field

Handle magnets consciously. Their immense force can surprise even experienced users. Stay alert and respect their power.

Life threat

Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

Fire warning

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

GPS Danger

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

Eye protection

Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them shattering into small pieces.

Magnetic media

Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Sensitization to coating

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease working with magnets and wear gloves.

Caution! More info about risks in the article: Safety of working with magnets.
