Grip strength drops significantly with every mm of distance. Note that every additional insulation layer (e.g., contamination, varnish, veneer) significantly reduces the pull force. Magnets work most effectively during direct contact; distance nullifies the power. Observe how flashily the load capacity drop, when the product does not touch flatly to the steel surface. When calculating the mounting, eliminate redundant distances.

This section defines the estimated force needed to cause the slippage of the magnet down on a upright metal surface (considering typical friction coefficient). The holding force is a function of the distance between the magnet and the metal.

When hanging a element on a vertical wall (e.g., a board), it you can count on just approx. 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that products slip easier than they pull off. Designing a wall mount? Note that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the element will give way down under a significantly smaller cargo. Utilizing a rubberized coating can effectively increase the grip.

A thin sheet cannot conduct the entire magnetic field, which wastes potential of the magnet. Should you mount a strong magnet to a thin surface, the flux will pass right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's potential, you need a suitably thick backing of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the product holds weaker. We recommend selecting the steel cross-section based on the following data.

Ordinary NdFeB products irreversibly lose power after exceeding the maximum temperature. Avoid high temperatures – heat can permanently demagnetize this magnet. As the temperature rises, the neodymium's power briefly drops. Avoid using this magnet close to ovens exceeding its working range. Too high temperature will result in destruction of magnetic properties.

*Important note: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress compared to rod magnets. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and steel setup. Such a system of two magnets generates a stronger field and a further horizon of performance. Want to build a powerful holder? Apply two magnets instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the collision energy is huge. The repulsion force is a bit weaker than the connection force, but still large.
*Field value between like poles reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Important: Results demonstrate sliding force of two same neodymium magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a large risk to electronic devices as well as pacemakers. These NdFeB products generate a flux that disrupts operation of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or injury to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when playing 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. Buoyancy helps in lifting finds.

1. Sliding resistance

*Caution: On a vertical surface, the magnet holds only approx. 20-30% of its max power.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) drastically limits the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.71

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 a very strong cylinder magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø45x30 mm, guarantees the highest energy density. This specific item boasts a tolerance of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 69.46 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 681.39 N with a weight of only 357.85 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, 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, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are suitable for the majority 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 (Ø45x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø45x30 mm, which, at a weight of 357.85 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 69.46 kg (force ~681.39 N), which, with such defined 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.

This cylinder is magnetized axially (along the height of 30 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard 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.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Besides their immense field intensity, neodymium magnets offer the following advantages:

They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
They have excellent resistance to magnetic field loss when exposed to external magnetic sources,
The use of an refined layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnetic induction on the surface of the magnet turns out to be very high,
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 machining and adapting to specific needs,
Huge importance in electronics industry – they are commonly used in HDD drives, motor assemblies, medical devices, as well as modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems

Cons

Disadvantages of neodymium magnets:

At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using cover - magnetic mount.
Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these products can complicate diagnosis medical in case of swallowing.
With mass production the cost of neodymium magnets can be a barrier,

Lifting parameters

Highest magnetic holding force – what it depends on?

Information about lifting capacity is the result of a measurement for optimal configuration, including:

using a plate made of mild steel, functioning as a circuit closing element
whose transverse dimension equals approx. 10 mm
with an polished contact surface
without any clearance between the magnet and steel
during pulling in a direction perpendicular to the mounting surface
in neutral thermal conditions

Determinants of lifting force in real conditions

Please note that the magnet holding will differ influenced by the following factors, in order of importance:

Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Plate material – mild steel gives the best results. Higher carbon content decrease magnetic properties and lifting capacity.
Base smoothness – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet and the plate decreases the load capacity.

H&S for magnets

ICD Warning

For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Handling guide

Be careful. Neodymium magnets attract from a long distance and snap with massive power, often faster than you can move away.

Fire warning

Dust created during machining of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Physical harm

Large magnets can smash fingers in a fraction of a second. Do not place your hand between two strong magnets.

Keep away from computers

Equipment safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).

Always store magnets away from children. Ingestion danger is high, and the effects of magnets clamping inside the body are tragic.

Warning for allergy sufferers

Certain individuals have a sensitization to nickel, which is the standard coating for neodymium magnets. Prolonged contact may cause an allergic reaction. We strongly advise wear protective gloves.

Threat to navigation

Note: rare earth magnets produce a field that disrupts sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.

Fragile material

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

Operating temperature

Avoid heat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Attention! More info about risks in the article: Magnet Safety Guide.
