Technical analysis of the product - report

The following data are the direct effect of a engineering calculation. Values were calculated on models for the material Nd₂Fe₁₄B. Actual conditions may deviate from the simulation results. Treat these data as a reference point for designers.

Table 1: Static force (force vs gap) - power drop
MW 16x9 / N38

Distance (mm)	Induction (Gauss) / mT	Pull Force (kg/lbs/g/N)	Risk Status
0 mm	4628 Gs 462.8 mT	8.53 kg / 18.81 pounds 8530.0 g / 83.7 N	strong

10 mm	873 Gs 87.3 mT	0.30 kg / 0.67 pounds 303.3 g / 3.0 N	weak grip
15 mm	411 Gs 41.1 mT	0.07 kg / 0.15 pounds 67.3 g / 0.7 N	weak grip
20 mm	220 Gs 22.0 mT	0.02 kg / 0.04 pounds 19.3 g / 0.2 N	weak grip

50 mm	22 Gs 2.2 mT	0.00 kg / 0.00 pounds 0.2 g / 0.0 N	weak grip

Magnetic force weakens sharply with every mm of gap. Remember that every additional insulation layer (e.g., dirt, varnish, dust) significantly weakens the grip. Neodymiums operate optimally in perfect adhesion; air break weakens the power. Notice how quickly the load capacity fall, when the magnet does not touch flatly to the steel surface. When planning the assembly, avoid redundant distances.

The following data indicates the estimated shear load necessary to cause the sliding of the magnet down along a upright steel plate (considering typical friction coefficient). This parameter depends on the gap size between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 16x9 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.56 kg / 5.64 pounds 2559.0 g / 25.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.71 kg / 3.76 pounds 1706.0 g / 16.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.85 kg / 1.88 pounds 853.0 g / 8.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.27 kg / 9.40 pounds 4265.0 g / 41.8 N

When placing a magnet on a vertical plane (e.g., a fridge), it will maintain only about 1/5 of its nominal power. Gravitational force and a weak degree of grip mean that holders move down faster than they detach. Designing a hanger? Note that the shear force is significantly lower than the maximum static pull force. On a painted metal, the holder will slide down under a noticeably lighter weight. Utilizing a rubberized pad can significantly raise the stability.

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.85 kg / 1.88 pounds 853.0 g / 8.4 N

2 mm	50%	4.27 kg / 9.40 pounds 4265.0 g / 41.8 N
3 mm	75%	6.40 kg / 14.10 pounds 6397.5 g / 62.8 N
5 mm	100%	8.53 kg / 18.81 pounds 8530.0 g / 83.7 N

11 mm	100%	8.53 kg / 18.81 pounds 8530.0 g / 83.7 N
12 mm	100%	8.53 kg / 18.81 pounds 8530.0 g / 83.7 N

A thin sheet is not enough to focus the entire magnetic field, which weakens actual performance of the holder. If you attach a powerful product to a too thin substrate, the field will pass right through and the holding will be smaller. To utilize 100% of this neodymium's potential, you need a suitably thick piece of metal. The saturation effect causes that on delicate walls (e.g., thin profiles), the magnet works worse. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose strength past the thermal threshold. Protect against heat – excessive heat can permanently demagnetize this product. With every degree above norm, the neodymium's capacity briefly lowers. Avoid using this magnet near heat sources higher than its working range. Too high temperature will result in irreversible degradation of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) are more susceptible to demagnetization sooner than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a much further distance than a neodymium and metal combination. The setup of magnet-to-magnet produces a massive flux and a further horizon of action. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the impact force is massive. The levitation is a bit weaker than the attraction, but still large.
*Flux density between like poles is approximately ~0 Gs at the geometric center of the gap (due to field cancellation).
* Results demonstrate sliding force of two same neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to electronics and pacemakers. These neodymiums produce a field that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field acts through matter and glass. Exceptional care must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Magnetic elements are very brittle – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can cause material chips or injury to fingers. Be sure to control the product during mounting 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 safety glasses when handling 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.

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

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

2. Steel saturation

*Thin metal sheet (e.g. computer case) drastically weakens 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) = 0.63

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 a very strong cylinder magnet, made from durable NdFeB material, which, at dimensions of Ø16x9 mm, guarantees maximum efficiency. The MW 16x9 / N38 component features high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 8.53 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 successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 83.64 N with a weight of only 13.57 g, this cylindrical magnet is indispensable in miniature devices 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., 16.1 mm) using epoxy glues. To ensure stability in automation, anaerobic resins 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 modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø16x9), 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 Ø16x9 mm, which, at a weight of 13.57 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 8.53 kg (force ~83.64 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 9 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 neodymium magnets.

Pros

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

They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
They feature excellent resistance to weakening of magnetic properties when exposed to external fields,
In other words, due to the shiny finish of nickel, the element gains a professional look,
Neodymium magnets create maximum magnetic induction on a contact point, which increases force concentration,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
In view of the possibility of flexible molding and adaptation to custom projects, magnetic components can be manufactured in a variety of shapes and sizes, which makes them more universal,
Wide application in electronics industry – they are used in computer drives, electric drive systems, medical equipment, as well as modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of neodymium magnets:

To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
Limited ability of producing threads in the magnet and complicated forms - preferred is a housing - mounting mechanism.
Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?

The specified lifting capacity represents the maximum value, measured under ideal test conditions, namely:

with the use of a yoke made of special test steel, ensuring full magnetic saturation
whose transverse dimension equals approx. 10 mm
with a surface cleaned and smooth
with direct contact (without impurities)
for force acting at a right angle (pull-off, not shear)
at ambient temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

It is worth knowing that the application force may be lower depending on elements below, starting with the most relevant:

Clearance – existence of any layer (rust, dirt, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
Material composition – different alloys attracts identically. Alloy additives worsen the attraction effect.
Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

H&S for magnets

Conscious usage

Handle magnets with awareness. Their huge power can surprise even professionals. Plan your moves and do not underestimate their force.

Swallowing risk

Always store magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are tragic.

Fire warning

Dust created during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Magnets are brittle

Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Danger to pacemakers

Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.

Bodily injuries

Large magnets can crush fingers in a fraction of a second. Never put your hand between two strong magnets.

Nickel coating and allergies

A percentage of the population experience a hypersensitivity to nickel, which is the standard coating for neodymium magnets. Prolonged contact can result in an allergic reaction. We recommend use protective gloves.

Permanent damage

Do not overheat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Threat to navigation

GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Magnetic media

Equipment safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
