Grip strength drops drastically with every mm of spacing. Remember that every additional insulation layer (e.g., contamination, varnish, veneer) significantly reduces the pull force. Magnets work optimally during direct contact; distance nullifies the power. See how quickly the parameters plummet, when the product does not adhere flatly to the metal substrate. When planning the assembly, discard redundant distances.

The table below calculates the theoretical holding capacity sufficient to initiate the sliding of the magnet vertically against a upright metal surface (assuming standard friction coefficient). The holding force varies with the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 38x3.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.53 kg / 3.37 pounds 1527.0 g / 15.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.02 kg / 2.24 pounds 1018.0 g / 10.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.51 kg / 1.12 pounds 509.0 g / 5.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.55 kg / 5.61 pounds 2545.0 g / 25.0 N

When placing a magnet on a vertical surface (e.g., a board), it will maintain just about 1/5 of its nominal power. Gravitational force and a weak degree of grip cause that products slide down easier than they detach. Planning a vertical fastening? Note that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the element will slide down under a much lighter cargo. Utilizing a rubberized pad can significantly increase the grip.

12 mm	100%	5.09 kg / 11.22 pounds 5090.0 g / 49.9 N

A thin metal plate cannot absorb the full magnetic flux, which wastes potential of the magnet. Should you attach a powerful product to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To utilize 100% of this magnet's power, you require a sufficiently solid backing of steel. The material oversaturation means that on delicate walls (e.g., car bodies), the holder holds weaker. We suggest choosing the steel dimension based on the following data.

Standard neodymium magnets change their properties power above the temperature limit. Avoid high temperatures – high temperature can permanently damage this magnet. With every degree above norm, the magnet's force briefly decreases. Refrain from using this magnet close to heaters higher than its working range. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) are more susceptible to demagnetization sooner than long magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a much further distance than a neodymium and metal combination. The setup of two magnets generates a stronger field and a further horizon of action. Planning to create a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the impact force is huge. The levitation is marginally weaker than the connection force, but still significant.
*Flux density between like poles is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Note: Figures apply to shear force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to electronic devices and pacemakers. These NdFeB products generate a flux that destroys function of sensitive medical devices. Remember: the unseen radiation 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, HDD media, or precise measuring instruments.

Magnetic elements are prone to chipping – a collision with steel can result in shattering. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when working with large magnets.

Rust risk: 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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Note: On a vertical wall, the magnet holds merely ~20% of its max power.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.14

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 exceptionally strong rod magnet, produced from durable NdFeB material, which, at dimensions of Ø38x3.5 mm, guarantees the highest energy density. This specific item features high dimensional repeatability and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 5.09 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 49.91 N with a weight of only 29.77 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 38.1 mm) using epoxy glues. To ensure long-term durability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø38x3.5), 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 Ø38x3.5 mm, which, at a weight of 29.77 g, makes it an element with impressive magnetic energy density. The value of 49.91 N means that the magnet is capable of holding a weight many times exceeding its own mass of 29.77 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 38 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 and weaknesses of neodymium magnets.

Benefits

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

They retain magnetic properties for nearly 10 years – the loss is just ~1% (based on simulations),
They show high resistance to demagnetization induced by external magnetic fields,
In other words, due to the metallic layer of silver, the element gains visual value,
Magnetic induction on the top side of the magnet turns out to be exceptional,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Due to the potential of precise molding and customization to specialized needs, magnetic components can be modeled in a broad palette of forms and dimensions, which makes them more universal,
Key role in future technologies – they are utilized in data components, motor assemblies, precision medical tools, as well as modern systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in compact constructions

Cons

Disadvantages of neodymium magnets:

At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can reduce 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 magnets in rubber or plastics, which secure oxidation and corrosion.
We suggest cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex shapes.
Possible danger related to microscopic parts of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these devices are able to complicate diagnosis medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Maximum holding power of the magnet – what affects it?

Holding force of 5.09 kg is a theoretical maximum value executed under standard conditions:

with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
possessing a massiveness of min. 10 mm to ensure full flux closure
with an ideally smooth contact surface
under conditions of ideal adhesion (surface-to-surface)
for force acting at a right angle (in the magnet axis)
in temp. approx. 20°C

Practical aspects of lifting capacity – factors

In real-world applications, the actual holding force depends on a number of factors, listed from crucial:

Distance – existence of any layer (paint, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Base massiveness – too thin plate does not close the flux, causing part of the flux to be lost into the air.
Material composition – not every steel reacts the same. Alloy additives weaken the attraction effect.
Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.

Warnings

Life threat

Warning for patients: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.

Demagnetization risk

Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.

Safe operation

Handle with care. Rare earth magnets act from a long distance and snap with massive power, often faster than you can move away.

Allergy Warning

A percentage of the population suffer from a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in an allergic reaction. We strongly advise wear safety gloves.

Impact on smartphones

A strong magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Do not bring magnets near a smartphone to prevent damaging the sensors.

Flammability

Powder created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Crushing risk

Large magnets can smash fingers instantly. Under no circumstances put your hand between two attracting surfaces.

Danger to the youngest

Strictly store magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are very dangerous.

Magnets are brittle

Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Safe distance

Intense magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
