Magnetic force drops significantly per each millimeter of spacing. Remember that even a very thin break (e.g., contamination, varnish, dust) significantly reduces the pull force. Neodymiums hold most effectively at the point of direct contact; gap kills the force. Analyze how flashily the pull force fall, when the magnet does not adhere tightly to the steel surface. When designing the arrangement, discard additional spacers.

The following data calculates the approximate force necessary to initiate the sliding of the magnet down against a upright steel wall (assuming typical friction coefficient). This value is relative to the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MW 9x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.58 kg / 1.28 LBS 582.0 g / 5.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.39 kg / 0.86 LBS 388.0 g / 3.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.43 LBS 194.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.97 kg / 2.14 LBS 970.0 g / 9.5 N

When hanging a holder on a upright surface (e.g., a fridge), it you can count on barely about 1/5 of its nominal power. Gravity as well as a low friction coefficient influence the fact that magnets slide down faster than they pull off. Planning a wall mount? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the holder will slide down under a significantly smaller weight. Using a rubber layer can effectively improve the result.

A thin metal plate is incapable of take in the full magnetic flux, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To squeeze full efficiency of this magnet's power, you need a suitably thick piece of metal. The saturation phenomenon causes that on sheet metal structures (e.g., appliance housings), the magnet works worse. We suggest choosing the steel dimension according to the table below.

Ordinary NdFeB products irreversibly lose parameters after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly demagnetize this product. With every degree above norm, the neodymium's power momentarily lowers. Refrain from using this product near heat sources exceeding its working range. Too high temperature will result in destruction of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) may lose charge permanently under lower heat stress than long magnets. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnets attract each other from a much further distance than a neodymium and metal setup. The connection of magnet-to-magnet produces a massive flux and a wider radius of action. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the impact force is extreme. The levitation is slightly lower than the connection force, but still impressive.
*The magnetic induction between like poles reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Figures apply to sliding force of two same magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to IT equipment and medical implants. These magnets generate a field that destroys function of digital equipment. Be aware: the unseen radiation penetrates the body and glass. Exceptional care must be exercised by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or injury to fingers. 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 ends with a crack of the magnet. Wear eye protection when playing with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Note: On a vertical surface, the magnet retains just a fraction of its max power.

2. Plate thickness effect

*Thin steel (e.g. computer case) drastically limits the holding force.

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.44

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 incredibly powerful cylindrical magnet, manufactured from modern NdFeB material, which, at dimensions of Ø9x3 mm, guarantees the highest energy density. The MW 9x3 / 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. 1.94 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical 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 high power of 18.99 N with a weight of only 1.43 g, this rod is indispensable in electronics 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 professional 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 strong enough for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø9x3), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø9x3 mm, which, at a weight of 1.43 g, makes it an element with high magnetic energy density. The value of 18.99 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.43 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 9 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.

Advantages as well as disadvantages of rare earth magnets.

Advantages

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

They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
They do not lose their magnetic properties even under external field action,
By applying a reflective coating of nickel, the element acquires an aesthetic look,
Magnets have extremely high magnetic induction on the outer layer,
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 the potential of flexible molding and customization to individualized solutions, NdFeB magnets can be created in a wide range of forms and dimensions, which expands the range of possible applications,
Key role in electronics industry – they find application in HDD drives, motor assemblies, diagnostic systems, as well as multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Limited ability of producing threads in the magnet and complex forms - recommended is casing - mounting mechanism.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices are able to be problematic in diagnostics medical in case of swallowing.
With budget limitations the cost of neodymium magnets is economically unviable,

Lifting parameters

Highest magnetic holding force – what affects it?

Information about lifting capacity was determined for optimal configuration, assuming:

with the use of a yoke made of special test steel, guaranteeing maximum field concentration
possessing a massiveness of min. 10 mm to avoid saturation
characterized by even structure
under conditions of ideal adhesion (metal-to-metal)
under axial force direction (90-degree angle)
in temp. approx. 20°C

Determinants of lifting force in real conditions

In real-world applications, the actual holding force depends on several key aspects, listed from the most important:

Distance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Steel type – mild steel attracts best. Alloy steels reduce magnetic permeability and lifting capacity.
Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Thermal conditions – NdFeB sinters 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 measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Warnings

Maximum temperature

Control the heat. Heating the magnet to high heat will destroy its properties and strength.

Sensitization to coating

Medical facts indicate that nickel (the usual finish) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands or select coated magnets.

Keep away from computers

Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.

Dust is flammable

Fire warning: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.

Magnetic interference

GPS units and smartphones are highly susceptible to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.

Crushing force

Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!

Warning for heart patients

For implant holders: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.

Respect the power

Use magnets consciously. Their huge power can surprise even professionals. Stay alert and do not underestimate their force.

Adults only

Only for adults. Small elements can be swallowed, causing intestinal necrosis. Keep away from children and animals.

Beware of splinters

NdFeB magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets leads to them cracking into small pieces.
