Grip strength weakens drastically with every mm of spacing. Note that every additional insulation layer (e.g., contamination, varnish, dust) noticeably weakens the grip. Neodymiums hold optimally at the point of direct contact; air break weakens the power. See how rapidly the pull force plummet, when the magnet does not adhere tightly to the steel surface. When calculating the mounting, discard additional spacers.

This section calculates the estimated force needed to initiate the shifting of the magnet downwards against a upright steel wall (considering typical friction coefficient). This parameter varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 15x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.86 kg / 1.90 LBS 861.0 g / 8.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.57 kg / 1.27 LBS 574.0 g / 5.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.29 kg / 0.63 LBS 287.0 g / 2.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.44 kg / 3.16 LBS 1435.0 g / 14.1 N

When mounting a magnet on a upright wall (e.g., a fridge), it will maintain only about 1/5 of its maximum pull force. Gravitational force as well as a low friction coefficient mean that holders slide down easier than they pull off. Want to create a wall mount? Note that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the element will give way down under a significantly smaller weight. Using a rubber coating can effectively increase the grip.

A too thin steel is incapable of take in the entire magnetic field, which weakens actual performance of the magnet. Should you mount a strong magnet to a too thin substrate, the field will pass right through and the holding will be smaller. To squeeze 100% of this magnet's power, you need a suitably thick piece of metal. The material oversaturation means that on thin elements (e.g., thin profiles), the magnet works worse. We recommend selecting the steel dimension based on the following data.

Classic neodymiums change their properties strength above the temperature limit. Protect against heat – heat can permanently destroy this product. With every degree above norm, the magnet's power temporarily lowers. Do not use this magnet close to heaters exceeding its working range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) are more susceptible to demagnetization sooner compared to rod magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two magnets attract each other from a much further distance than a magnet and steel combination. The connection of two magnets produces a massive flux and a larger range of action. Designing a solid fastener? Use a pair of magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the collision energy is extreme. The levitation is slightly lower than the attraction, but still impressive.
*The magnetic induction between like poles drops to ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Attention: Calculations apply to friction force of two same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a large risk to electronics and medical implants. These neodymiums produce a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and housings. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - collision effects
MW 15x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	27.62 km/h (7.67 m/s)	0.12 J
30 mm	46.91 km/h (13.03 m/s)	0.34 J
50 mm	60.56 km/h (16.82 m/s)	0.56 J
100 mm	85.64 km/h (23.79 m/s)	1.13 J

Magnetic elements are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can trigger coating fragments or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't hit violently against the metal. A collision at high speed means shattering of the neodymium. Wear eye protection when handling with large magnets.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Efficiency vs thickness

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

3. Power loss vs temp

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.29

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 offered product is a very strong cylinder magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø15x3 mm, guarantees the highest energy density. This specific item boasts an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 2.87 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 28.14 N with a weight of only 3.98 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method 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 do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø15x3), 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 Ø15x3 mm, which, at a weight of 3.98 g, makes it an element with high magnetic energy density. The value of 28.14 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.98 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 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 diametrically if your project requires it.

Advantages and disadvantages of neodymium magnets.

Strengths

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

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
Magnets perfectly defend themselves against demagnetization caused by ambient magnetic noise,
In other words, due to the metallic finish of gold, the element looks attractive,
Magnets are characterized by very high magnetic induction on the outer side,
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...
In view of the option of free shaping and adaptation to unique projects, NdFeB magnets can be created in a broad palette of forms and dimensions, which amplifies use scope,
Significant place in high-tech industry – they are utilized in data components, electromotive mechanisms, diagnostic systems, and industrial machines.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Limitations

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing nuts and complex forms in magnets, we propose using cover - magnetic mechanism.
Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that tiny parts of these devices can complicate diagnosis medical after entering the body.
Due to neodymium price, their price exceeds standard values,

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what contributes to it?

The load parameter shown refers to the peak performance, recorded under ideal test conditions, specifically:

on a block made of mild steel, optimally conducting the magnetic flux
possessing a massiveness of at least 10 mm to ensure full flux closure
characterized by smoothness
with total lack of distance (no paint)
during detachment in a direction perpendicular to the plane
in temp. approx. 20°C

Magnet lifting force in use – key factors

Bear in mind that the application force may be lower depending on the following factors, starting with the most relevant:

Air gap (betwixt the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
Material composition – not every steel attracts identically. High carbon content weaken the attraction effect.
Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate lowers the load capacity.

H&S for magnets

Demagnetization risk

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.

Threat to electronics

Equipment safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, timepieces).

Magnets are brittle

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Serious injuries

Protect your hands. Two powerful magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!

Machining danger

Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Do not underestimate power

Exercise caution. Neodymium magnets act from a distance and connect with huge force, often faster than you can react.

Pacemakers

Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Keep away from electronics

An intense magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to prevent breaking the sensors.

Nickel allergy

Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness occurs, immediately stop handling magnets and use protective gear.

This is not a toy

Strictly store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are very dangerous.
