Magnetic force decreases drastically with every mm of gap. Remember that every additional insulation layer (e.g., dirt, varnish, dust) significantly reduces the pull force. Magnetic products operate most effectively at the point of direct contact; gap weakens the force. See how quickly the parameters fall, when the product does not touch directly to the metal substrate. When designing the mounting, eliminate redundant distances.

This section indicates the estimated weight limit sufficient to start the sliding of the magnet vertically along a vertical metal surface (assuming standard friction coefficient). This value depends on the gap size between the magnet and the surface.

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.60 kg / 3.52 pounds 1596.0 g / 15.7 N

When hanging a magnet on a vertical surface (e.g., a fridge), it will maintain just approx. 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip cause that magnets slide down easier than they pop off the substrate. Designing a vertical fastening? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a significantly smaller load. Using a rubber coating can effectively raise the stability.

A thin sheet is not enough to take in the entire magnetic field, which wastes potential of the magnet. Should you mount a strong magnet to a weak sheet, the flux will penetrate right through and the pull force will drop sharply. To achieve 100% of this magnet's power, you require a sufficiently solid backing of metal. The saturation effect causes that on sheet metal structures (e.g., car bodies), the holder holds weaker. We recommend selecting the steel dimension based on the following data.

Standard neodymium magnets change their properties strength after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly damage this magnet. With increasing heat, the magnet's capacity temporarily lowers. Do not use this magnet in hot environments exceeding its operating temperature limit. Ignoring the limit will result in destruction of magnetic properties.

*Important note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) may lose charge permanently at lower temperatures than taller cylinders. Red status in the table signals permanent field degradation for this particular item.

Two strong neodymiums attract each other from a much further distance than a magnet and sheet combination. The connection of two magnets produces a massive flux and a wider radius of operation. Want to build a solid fastener? Apply two magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is extreme. The levitation is marginally weaker than the attraction, but still significant.
*Flux density between like poles is approximately ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Figures apply to sliding force of dual matching magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to electronic devices and medical implants. These NdFeB products produce a flux that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field penetrates the body and housings. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MW 25x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	22.87 km/h (6.35 m/s)	0.37 J
30 mm	36.43 km/h (10.12 m/s)	0.94 J
50 mm	46.96 km/h (13.04 m/s)	1.57 J
100 mm	66.40 km/h (18.44 m/s)	3.13 J

Neodymium magnets are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Impact energy can cause material chips or injury to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear eye protection when handling with powerful specimens.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. 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 ~20% of its max power.

2. Steel thickness impact

*Thin steel (e.g. computer case) significantly reduces 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) = 0.29

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.

This product is a very strong cylinder magnet, composed of modern NdFeB material, which, with dimensions of Ø25x5 mm, guarantees the highest energy density. This specific item features an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 7.98 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 78.25 N with a weight of only 18.41 g, this rod is indispensable in miniature devices 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 chipping the coating of this precision component. To ensure long-term durability in automation, anaerobic resins 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 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø25x5), 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 Ø25x5 mm, which, at a weight of 18.41 g, makes it an element with high magnetic energy density. The value of 78.25 N means that the magnet is capable of holding a weight many times exceeding its own mass of 18.41 g. 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 25 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.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Advantages

Apart from their notable power, neodymium magnets have these key benefits:

Their magnetic field is maintained, and after around ten years it drops only by ~1% (according to research),
They retain their magnetic properties even under strong external field,
In other words, due to the aesthetic layer of gold, the element gains visual value,
The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Considering the ability of free forming and customization to individualized projects, neodymium magnets can be manufactured in a broad palette of shapes and sizes, which makes them more universal,
Key role in modern industrial fields – they are commonly used in data components, brushless drives, medical equipment, as well as modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Drawbacks and weaknesses of neodymium magnets and proposals for their use:

At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We suggest a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated shapes.
Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small components of these devices are able to complicate diagnosis medical when they are in the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

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

Breakaway force is the result of a measurement for the most favorable conditions, including:

with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
with a cross-section of at least 10 mm
with a plane free of scratches
under conditions of no distance (metal-to-metal)
during pulling in a direction perpendicular to the mounting surface
in temp. approx. 20°C

Practical lifting capacity: influencing factors

During everyday use, the actual lifting capacity results from many variables, listed from most significant:

Clearance – existence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Material type – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Precautions when working with NdFeB magnets

Do not drill into magnets

Fire warning: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

This is not a toy

Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Keep out of reach of kids and pets.

ICD Warning

People with a heart stimulator have to keep an large gap from magnets. The magnetism can disrupt the operation of the life-saving device.

Pinching danger

Risk of injury: The attraction force is so great that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.

Permanent damage

Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.

Beware of splinters

Neodymium magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them cracking into shards.

Impact on smartphones

A strong magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a smartphone to prevent breaking the sensors.

Cards and drives

Powerful magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Nickel allergy

A percentage of the population have a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Extended handling may cause skin redness. We strongly advise use protective gloves.

Handling rules

Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
