Physical modeling of the product - data

The following data constitute the result of a mathematical analysis. Values were calculated on models for the material Nd₂Fe₁₄B. Actual performance may differ. Treat these calculations as a preliminary roadmap when designing systems.

Pulling power decreases drastically per each millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, varnish, dust) strongly reduces the pull force. Magnets hold strongest during direct contact; distance weakens the force. Analyze how quickly the pull force plummet, when the magnet does not adhere tightly to the metal substrate. When designing the assembly, discard unnecessary gaps.

The following data defines the estimated weight limit sufficient to cause the slippage of the magnet vertically against a vertical steel plate (considering typical friction). The holding force is relative to the gap size between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 5x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.17 kg / 0.37 pounds 168.0 g / 1.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.11 kg / 0.25 pounds 112.0 g / 1.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.06 kg / 0.12 pounds 56.0 g / 0.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.28 kg / 0.62 pounds 280.0 g / 2.7 N

When placing a magnet on a upright wall (e.g., a fridge), it you can count on only about 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient influence the fact that magnets slip easier than they pop off the substrate. Want to create a hanger? Consider that the shear force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will give way down under a significantly smaller cargo. Application of an anti-slip pad can effectively increase the grip.

12 mm	100%	0.56 kg / 1.23 pounds 560.0 g / 5.5 N

A thin metal plate is unable to focus the full magnetic flux, which weakens actual performance of the holder. If you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To achieve 100% of this magnet's power, you need a suitably thick backing of metal. The material oversaturation means that on sheet metal structures (e.g., appliance housings), the holder works worse. We suggest choosing the steel dimension based on the following data.

Standard neodymium magnets change their properties power above the temperature limit. Watch out for overheating – heat can irreversibly destroy this product. With every degree above norm, the neodymium's power momentarily drops. Avoid using this magnet in hot environments higher than its safe range. Ignoring the limit will cause irreversible degradation of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a wider radius than a magnet and sheet setup. The setup of two magnets produces a massive flux and a larger range of action. Want to build a powerful holder? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when connecting a pair of magnets, the collision energy is huge. The repulsion force is a bit weaker than the connection force, but still large.
*Field value in repulsion mode is approximately ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Important: Results apply to friction force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to IT equipment and pacemakers. These NdFeB products generate a flux that disrupts operation of digital equipment. Be aware: the unseen radiation passes through tissues and glass. Exceptional care must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the magnet. Use safety goggles when working with large magnets.

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. Buoyancy helps in lifting finds.

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

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

*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) = 1.21

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 presented product is an extremely powerful cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø5x10 mm, guarantees optimal power. The MW 5x10 / N38 component is characterized by an accuracy of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 0.56 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 5.45 N with a weight of only 1.47 g, this rod is indispensable in electronics and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 5.1 mm) using epoxy glues. To ensure long-term durability in automation, 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 90% 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 (Ø5x10), 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 Ø5x10 mm, which, at a weight of 1.47 g, makes it an element with impressive magnetic energy density. The value of 5.45 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.47 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 10 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Strengths as well as weaknesses of rare earth magnets.

Advantages

In addition to their long-term stability, neodymium magnets provide the following advantages:

They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
Neodymium magnets are distinguished by extremely resistant to magnetic field loss caused by external field sources,
The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Thanks to modularity in designing and the capacity to modify to complex applications,
Versatile presence in future technologies – they are used in computer drives, electric motors, medical equipment, also other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Weaknesses

Problematic aspects of neodymium magnets: weaknesses and usage proposals

At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited possibility of producing nuts in the magnet and complex forms - preferred is a housing - magnet mounting.
Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small elements of these products are able to complicate diagnosis medical after entering the body.
Due to expensive raw materials, their price is higher than average,

Holding force characteristics

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

The load parameter shown represents the limit force, recorded under optimal environment, specifically:

on a base made of mild steel, perfectly concentrating the magnetic flux
whose transverse dimension equals approx. 10 mm
characterized by smoothness
with zero gap (without impurities)
for force acting at a right angle (pull-off, not shear)
at room temperature

Key elements affecting lifting force

Bear in mind that the working load may be lower subject to elements below, starting with the most relevant:

Distance (betwixt the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Angle of force application – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
Plate thickness – too thin plate does not accept the full field, causing part of the flux to be lost into the air.
Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.

Precautions when working with neodymium magnets

This is not a toy

Only for adults. Tiny parts can be swallowed, leading to serious injuries. Store away from children and animals.

GPS and phone interference

GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.

Respect the power

Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Nickel allergy

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.

Do not overheat magnets

Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

Risk of cracking

NdFeB magnets are ceramic materials, which means they are very brittle. Clashing of two magnets leads to them shattering into small pieces.

Safe distance

Avoid bringing magnets near a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.

Implant safety

For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Do not drill into magnets

Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Crushing force

Danger of trauma: The pulling power is so great that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.
