Magnetic force weakens significantly with every subsequent millimeter of spacing. Remember that even the smallest gap (e.g., dirt, varnish, dust) significantly diminishes the holding power. Neodymiums operate strongest in perfect adhesion; gap weakens the force. Observe how flashily the pull force plummet, when the magnet does not touch tightly to the metal substrate. When calculating the assembly, avoid additional spacers.

This section indicates the theoretical force needed to start the slippage of the magnet vertically on a vertical metal surface (assuming standard friction coefficient). This parameter varies with the gap size between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MW 15x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.45 kg / 1.00 pounds 453.0 g / 4.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.30 kg / 0.67 pounds 302.0 g / 3.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.15 kg / 0.33 pounds 151.0 g / 1.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.76 kg / 1.66 pounds 755.0 g / 7.4 N

When hanging a holder on a vertical surface (e.g., a fridge), it will only hold barely approx. 20%-30% of its maximum pull force. Gravitational force as well as a low friction coefficient mean that magnets slip faster than they detach. Want to create a hanger? Note that the shear force is much weaker than the maximum static pull force. On a painted metal, the element will give way down under a much lighter weight. Application of an anti-slip coating can effectively increase the grip.

12 mm	100%	1.51 kg / 3.33 pounds 1510.0 g / 14.8 N

A too thin steel is not enough to absorb the entire magnetic field, which wastes potential of the holder. If you install a neodymium to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To squeeze the maximum of this neodymium's potential, you need a suitably thick piece of metal. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the magnet shows lower pull force. We advise picking the steel cross-section based on the following data.

Standard neodymium magnets lose parameters above the temperature limit. Protect against heat – high temperature can permanently destroy this product. With increasing heat, the neodymium's power briefly decreases. Refrain from using this product near heat sources higher than its safe range. Too high temperature will lead to permanent loss of magnetism.

*Technical advisory: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) are more susceptible to demagnetization under lower heat stress than long magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnets attract each other from a wider radius than a magnet and steel combination. The setup of two magnets creates a more powerful interaction and a further horizon of action. Planning to create a solid fastener? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is extreme. The levitation is marginally weaker than the attraction, but still large.
*Flux density in repulsion mode is approximately ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Results demonstrate shear force of a pair of matching magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (implants) - precautionary measures
MW 15x2 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	5.5 cm

Extremely neodym field is a serious hazard to electronic devices and pacemakers. These magnets generate a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

100 mm	76.13 km/h (21.15 m/s)	0.59 J

Magnetic elements are prone to chipping – a violent impact against metal causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or injury to skin. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when handling with large magnets.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Vertical hold

*Warning: On a vertical surface, the magnet retains just a fraction of its perpendicular strength.

2. Efficiency vs thickness

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

3. Heat tolerance

*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) = 0.20

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 presented product is an incredibly powerful rod magnet, composed of durable NdFeB material, which, with dimensions of Ø15x2 mm, guarantees maximum efficiency. The MW 15x2 / N38 component features high dimensional repeatability and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 1.51 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 14.84 N with a weight of only 2.65 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 15.1 mm) using two-component epoxy glues. 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 NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø15x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 15 mm and height 2 mm. The value of 14.84 N means that the magnet is capable of holding a weight many times exceeding its own mass of 2.65 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 15 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 rare earth magnets.

Advantages

Besides their exceptional pulling force, neodymium magnets offer the following advantages:

They do not lose strength, even over nearly ten years – the reduction in strength is only ~1% (according to tests),
They show high resistance to demagnetization induced by external field influence,
The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to look better,
The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Possibility of detailed creating and adjusting to precise needs,
Versatile presence in high-tech industry – they are used in HDD drives, brushless drives, medical devices, as well as complex engineering applications.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Cons

What to avoid - cons of neodymium magnets: application proposals

At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing threads and complex shapes in magnets, we propose using cover - magnetic holder.
Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Lifting parameters

Maximum lifting force for a neodymium magnet – what contributes to it?

Magnet power was determined for ideal contact conditions, including:

with the application of a sheet made of special test steel, ensuring maximum field concentration
whose thickness reaches at least 10 mm
with a surface free of scratches
under conditions of no distance (metal-to-metal)
during pulling in a direction vertical to the mounting surface
at room temperature

Practical lifting capacity: influencing factors

In real-world applications, the real power is determined by several key aspects, presented from most significant:

Distance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Steel type – mild steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
Surface finish – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the load capacity.

Safety rules for work with neodymium magnets

Do not overheat magnets

Avoid heat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).

Combustion hazard

Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.

This is not a toy

Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are fatal.

Warning for heart patients

For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.

Crushing force

Large magnets can smash fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.

Powerful field

Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can react.

Threat to navigation

Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Warning for allergy sufferers

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.

Protective goggles

Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets leads to them breaking into shards.

Protect data

Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
