Pulling power decreases significantly per each millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, varnish, veneer) strongly weakens the grip. Magnetic products work optimally during direct contact; air break drastically cuts the force. Observe how rapidly the load capacity fall, when the magnet does not adhere flatly to the steel surface. When designing the mounting, avoid redundant distances.

The following data indicates the approximate force required to initiate the downward movement of the magnet downwards along a upright steel wall (considering standard friction coefficient). This parameter depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	51.19 kg / 112.86 LBS 51192.0 g / 502.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	34.13 kg / 75.24 LBS 34128.0 g / 334.8 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	85.32 kg / 188.10 LBS 85320.0 g / 837.0 N

When hanging a holder on a upright plane (e.g., a car body), it will only hold barely about 20%-30% of nominal attraction strength. Gravity and a low friction coefficient mean that products slide down faster than they detach. Designing a hanger? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the magnet will slip down under a much lighter cargo. Using a rubber coating can effectively raise the stability.

A thin metal plate is incapable of conduct the full magnetic flux, which wastes potential of the magnet. Should you attach a powerful product to a weak sheet, the magnetism will pass right through and the pull force will drop sharply. To squeeze 100% of this neodymium's power, you require a sufficiently solid piece of metal. The material oversaturation means that on thin elements (e.g., thin profiles), the product works worse. We suggest choosing the steel dimension from these parameters.

Classic neodymiums change their properties power past the thermal threshold. Avoid high temperatures – heat can irreversibly damage this product. With increasing heat, the magnet's power temporarily drops. Refrain from using this product close to ovens exceeding its safe range. Ignoring the limit will result in irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than long magnets. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and steel setup. The connection of magnet-to-magnet generates a stronger field and a further horizon of performance. Planning to create a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is massive. The levitation is slightly lower than the attraction, but still large.
*The magnetic induction for N-N configuration drops to ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Attention: Estimates refer to shear force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a large risk to IT equipment as well as medical implants. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and housings. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

NdFeB products are delicate – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can cause material chips or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when playing with powerful specimens.

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Shear force

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

2. Steel saturation

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

3. Power loss vs temp

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.48

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 an extremely powerful cylinder magnet, manufactured from durable NdFeB material, which, with dimensions of Ø80x30 mm, guarantees maximum efficiency. The MW 80x30 / N38 component features high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 170.64 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Moreover, its 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 automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 1673.99 N with a weight of only 1130.97 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

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 stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are suitable for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø80x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø80x30 mm, which, at a weight of 1130.97 g, makes it an element with high magnetic energy density. The value of 1673.99 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1130.97 g. The product has a [NiCuNi] coating, which secures it 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 80 mm. 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 diametrically if your project requires it.

Pros and cons of neodymium magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They do not lose power, even over approximately 10 years – the drop in power is only ~1% (based on measurements),
They are resistant to demagnetization induced by external disturbances,
Thanks to the glossy finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to modularity in constructing and the capacity to adapt to specific needs,
Versatile presence in future technologies – they are commonly used in magnetic memories, drive modules, diagnostic systems, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions

Disadvantages

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce their power 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. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Additionally, small elements of these products can be problematic in diagnostics medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Holding force characteristics

Highest magnetic holding force – what contributes to it?

The declared magnet strength concerns the limit force, measured under laboratory conditions, namely:

with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
whose transverse dimension reaches at least 10 mm
with an ideally smooth touching surface
under conditions of ideal adhesion (surface-to-surface)
under vertical force vector (90-degree angle)
at conditions approx. 20°C

Lifting capacity in real conditions – factors

Real force is influenced by specific conditions, such as (from priority):

Gap (betwixt the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

NdFeB magnets are not intended for children. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a critical condition and requires urgent medical intervention.

Powerful field

Handle magnets with awareness. Their immense force can surprise even professionals. Be vigilant and respect their force.

Risk of cracking

Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.

Bodily injuries

Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Data carriers

Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).

Nickel allergy

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and wear gloves.

Danger to pacemakers

Warning for patients: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.

GPS Danger

A strong magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.

Operating temperature

Keep cool. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).

Combustion hazard

Fire warning: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.

Danger! Learn more about hazards in the article: Magnet Safety Guide.
