Technical analysis of the assembly - data

The following data are the outcome of a engineering simulation. Values are based on models for the class Nd₂Fe₁₄B. Real-world performance may differ from theoretical values. Please consider these data as a supplementary guide during assembly planning.

50 mm	5 Gs 0.5 mT	0.00 kg / 0.00 lbs 0.0 g / 0.0 N	weak grip

Pulling power decreases drastically per each millimeter of spacing. Note that even the smallest gap (e.g., contamination, varnish, veneer) noticeably reduces the pull force. Neodymiums operate strongest at the point of direct contact; gap nullifies the force. Observe how rapidly the parameters drop, when the product does not adhere directly to the metal substrate. When calculating the assembly, eliminate redundant distances.

Table 2: Slippage load (wall)
MW 5x30 / N38

50 mm	Stal (~0.2)	0.00 kg / 0.00 lbs 0.0 g / 0.0 N

The table below shows the approximate shear load needed to cause the slippage of the magnet vertically against a upright steel wall (considering typical friction coefficient). This parameter is relative to the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MW 5x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.14 kg / 0.30 lbs 135.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 lbs 90.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 lbs 45.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.50 lbs 225.0 g / 2.2 N

When placing a magnet on a upright plane (e.g., a board), it you can count on barely approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip cause that magnets move down faster than they pull off. Want to create a hanger? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will give way down under a noticeably lighter weight. Utilizing a rubberized coating can significantly increase the grip.

2 mm	50%	0.23 kg / 0.50 lbs 225.0 g / 2.2 N
3 mm	75%	0.34 kg / 0.74 lbs 337.5 g / 3.3 N
5 mm	100%	0.45 kg / 0.99 lbs 450.0 g / 4.4 N
10 mm	100%	0.45 kg / 0.99 lbs 450.0 g / 4.4 N
11 mm	100%	0.45 kg / 0.99 lbs 450.0 g / 4.4 N
12 mm	100%	0.45 kg / 0.99 lbs 450.0 g / 4.4 N

A thin metal plate is not enough to absorb the entire magnetic field, which squanders power of the magnet. If you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To utilize 100% of this neodymium's potential, you need a suitably thick backing of metal. The material oversaturation means that on sheet metal structures (e.g., appliance housings), the product shows lower pull force. We advise picking the steel thickness based on the following data.

Table 5: Thermal stability (stability) - resistance threshold
MW 5x30 / N38

20 °C	0.0%	0.45 kg / 0.99 lbs 450.0 g / 4.4 N	OK
40 °C	-2.2%	0.44 kg / 0.97 lbs 440.1 g / 4.3 N	OK

Ordinary NdFeB products change their properties power above the temperature limit. Watch out for overheating – high temperature can permanently demagnetize this magnet. As the temperature rises, the magnet's power briefly lowers. Do not use this product in hot environments exceeding its operating temperature limit. Too high temperature will cause irreversible degradation of magnetism.

*Technical advisory: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Red status in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and sheet combination. The connection of two magnets creates a more powerful interaction and a further horizon of action. Want to build a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Remember that when connecting a pair of magnets, the pinch force is extreme. The levitation is slightly lower than the attraction, but still impressive.
*Flux density in repulsion mode reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Results apply to friction force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to IT equipment as well as pacemakers. These magnets produce a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field acts through matter and housings. Special caution must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when playing with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Wall mount (shear)

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

2. Steel thickness impact

*Thin steel (e.g. computer case) drastically limits 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) = 1.59

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 an extremely powerful cylindrical magnet, composed of modern NdFeB material, which, at dimensions of Ø5x30 mm, guarantees maximum efficiency. The MW 5x30 / N38 model boasts a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 0.45 kg), this product is available off-the-shelf from our European logistics center, 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.

This model is ideal for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 4.40 N with a weight of only 4.42 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 5.1 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.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø5x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø5x30 mm, which, at a weight of 4.42 g, makes it an element with high magnetic energy density. The value of 4.40 N means that the magnet is capable of holding a weight many times exceeding its own mass of 4.42 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 5 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.

Pros and cons of Nd₂Fe₁₄B magnets.

Pros

Apart from their consistent power, neodymium magnets have these key benefits:

They do not lose strength, even during nearly 10 years – the reduction in power is only ~1% (based on measurements),
Magnets effectively resist against loss of magnetization caused by foreign field sources,
In other words, due to the smooth finish of gold, the element gains a professional look,
Magnets have very high magnetic induction on the working surface,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Possibility of custom shaping as well as modifying to individual requirements,
Huge importance in high-tech industry – they are used in data components, electric drive systems, advanced medical instruments, and technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Limitations

Cons of neodymium magnets: weaknesses and usage proposals

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
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.
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing threads and complicated shapes in magnets, we propose using a housing - magnetic holder.
Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, small components of these products are able to complicate diagnosis medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

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

Magnet power was defined for the most favorable conditions, assuming:

on a plate made of structural steel, effectively closing the magnetic flux
possessing a massiveness of at least 10 mm to ensure full flux closure
with a surface perfectly flat
with total lack of distance (without coatings)
for force applied at a right angle (in the magnet axis)
at room temperature

Magnet lifting force in use – key factors

Holding efficiency is influenced by working environment parameters, mainly (from most important):

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Base massiveness – too thin steel causes magnetic saturation, causing part of the flux to be lost into the air.
Chemical composition of the base – mild steel attracts best. Alloy steels decrease magnetic properties and lifting capacity.
Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, reducing force.
Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of neodymium magnets

Keep away from electronics

A strong magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.

Dust is flammable

Machining of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Adults only

Neodymium magnets are not suitable for play. Swallowing multiple magnets may result in them attracting across intestines, which constitutes a direct threat to life and necessitates urgent medical intervention.

Shattering risk

Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Finger safety

Protect your hands. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Powerful field

Handle with care. Rare earth magnets act from a distance and snap with huge force, often quicker than you can react.

Life threat

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

Safe distance

Device Safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Operating temperature

Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. This process is irreversible.

Skin irritation risks

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness happens, immediately stop working with magnets and wear gloves.
