Magnetic force drops sharply with every mm of distance. Note that even a microscopic distance (e.g., dirt, paint, veneer) strongly diminishes the holding power. Magnets operate most effectively in perfect adhesion; gap drastically cuts the force. Notice how quickly the load capacity plummet, when the product does not touch flatly to the metal substrate. When calculating the assembly, discard unnecessary gaps.

The following data shows the estimated shear load necessary to initiate the downward movement of the magnet down along a upright steel wall (assuming standard friction coefficient). This value depends on the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 6x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.35 kg / 0.76 lbs 345.0 g / 3.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.23 kg / 0.51 lbs 230.0 g / 2.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.11 kg / 0.25 lbs 115.0 g / 1.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.58 kg / 1.27 lbs 575.0 g / 5.6 N

When hanging a magnet on a vertical plane (e.g., a car body), it you can count on barely approx. 1/5 of its nominal power. Gravitational force and a low friction coefficient mean that magnets move down easier than they detach. Want to create a hanger? Remember that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slip down under a significantly smaller cargo. Application of an anti-slip pad can effectively increase the grip.

12 mm	100%	1.15 kg / 2.54 lbs 1150.0 g / 11.3 N

A too thin steel is unable to absorb the entire magnetic field, which squanders power of the magnet. Should you mount a strong magnet to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you need a suitably thick backing of steel. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the product holds weaker. We suggest choosing the steel cross-section according to the table below.

100 °C	-28.8%	0.82 kg / 1.81 lbs 818.8 g / 8.0 N

Classic neodymiums irreversibly lose power past the thermal threshold. Protect against heat – excessive heat can permanently damage this magnet. As the temperature rises, the neodymium's force temporarily drops. Refrain from using this magnet in hot environments exceeding its operating temperature limit. Ignoring the limit will cause permanent loss of magnetism.

*Important note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) may lose charge permanently sooner compared to rod magnets. Red status in the table signals permanent field degradation for this particular item.

Two strong neodymiums interact from a much further distance than a magnet and steel setup. The setup of two magnets creates a more powerful interaction and a wider radius of action. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is extreme. The levitation is a bit weaker than the attraction, but still significant.
*Flux density between like poles drops to ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Estimates demonstrate friction force of two same magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to electronic devices as well as pacemakers. These magnets produce a flux that destroys function of sensitive medical devices. Notice: the unseen radiation acts through matter and glass. Exceptional care must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Kinetic force can trigger coating fragments or painful pinches to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the neodymium. Use safety goggles when working with powerful specimens.

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. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

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

2. Steel saturation

*Thin steel (e.g. computer case) severely reduces the holding force.

3. Power loss vs temp

*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) = 0.59

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.

This product is an extremely powerful cylinder magnet, composed of advanced NdFeB material, which, at dimensions of Ø6x3 mm, guarantees maximum efficiency. The MW 6x3 / N38 component boasts high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.15 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 11.23 N with a weight of only 0.64 g, this rod is indispensable in electronics 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 stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø6x3), 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 Ø6x3 mm, which, at a weight of 0.64 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 1.15 kg (force ~11.23 N), which, with such compact dimensions, proves the high grade of the NdFeB material. 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 6 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 through the diameter if your project requires it.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Benefits

Besides their immense strength, neodymium magnets offer the following advantages:

They do not lose strength, even over around 10 years – the reduction in power is only ~1% (based on measurements),
They feature excellent resistance to weakening of magnetic properties due to external fields,
In other words, due to the shiny finish of silver, the element becomes visually attractive,
Neodymium magnets ensure maximum magnetic induction on a contact point, which allows for strong attraction,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Thanks to freedom in forming and the capacity to adapt to client solutions,
Huge importance in advanced technology sectors – they find application in data components, electromotive mechanisms, advanced medical instruments, and technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Limitations

What to avoid - cons of neodymium magnets: weaknesses and usage proposals

At very 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.
When exposed to high temperature, neodymium magnets suffer 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 - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small components of these products can be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Highest magnetic holding force – what contributes to it?

The force parameter is a result of laboratory testing conducted under the following configuration:

using a sheet made of high-permeability steel, serving as a ideal flux conductor
possessing a massiveness of minimum 10 mm to ensure full flux closure
with an ground touching surface
without the slightest clearance between the magnet and steel
under vertical force direction (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

It is worth knowing that the magnet holding will differ subject to elements below, in order of importance:

Gap (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
Steel type – mild steel attracts best. Alloy steels decrease magnetic permeability and holding force.
Surface quality – the more even 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 they can be stronger (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.

Safe handling of NdFeB magnets

Eye protection

Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Phone sensors

Be aware: rare earth magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.

Conscious usage

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

Heat sensitivity

Control the heat. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.

This is not a toy

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

Medical interference

Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Finger safety

Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Data carriers

Device Safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).

Dust explosion hazard

Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

Sensitization to coating

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop working with magnets and use protective gear.
