Technical modeling of the assembly - data

The following values constitute the direct effect of a mathematical calculation. Values rely on algorithms for the class Nd₂Fe₁₄B. Operational performance might slightly differ. Please consider these calculations as a preliminary roadmap when designing systems.

50 mm	132 Gs 13.2 mT	0.05 kg / 0.12 lbs 52.4 g / 0.5 N	weak grip

Pulling power drops significantly per each millimeter of gap. Remember that even the smallest gap (e.g., contamination, paint, veneer) noticeably weakens the grip. Magnetic products operate strongest during direct contact; gap nullifies the force. Observe how rapidly the pull force drop, when the magnet does not adhere flatly to the steel surface. When planning the mounting, avoid additional spacers.

The following data shows the estimated shear load necessary to cause the shifting of the magnet vertically against a vertical steel plate (considering typical friction). This value is relative to the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 38x12 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	9.84 kg / 21.69 lbs 9837.0 g / 96.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	6.56 kg / 14.46 lbs 6558.0 g / 64.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	3.28 kg / 7.23 lbs 3279.0 g / 32.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	16.40 kg / 36.14 lbs 16395.0 g / 160.8 N

When hanging a holder on a upright wall (e.g., a board), it will only hold just about 1/5 of its nominal power. Gravitational force and a low friction coefficient influence the fact that magnets move down faster than they pull off. Want to create a wall mount? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will slide down under a noticeably lighter cargo. Utilizing a rubberized layer can significantly increase the grip.

A thin sheet is incapable of focus the entire magnetic field, which wastes potential of the magnet. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's potential, you need a suitably thick element of metal. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the magnet works worse. We advise picking the steel thickness according to the table below.

Standard neodymium magnets lose parameters above the temperature limit. Avoid high temperatures – excessive heat can irreversibly demagnetize this magnet. With increasing heat, the magnet's capacity briefly decreases. Avoid using this magnet near heat sources higher than its operating temperature limit. Ignoring the limit will result in destruction of magnetic properties.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) risk losing magnetic properties sooner than taller cylinders. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnets attract each other from a wider radius than a magnet and steel setup. Such a system of magnet-to-magnet generates a stronger field and a wider radius of performance. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the collision energy is massive. The repulsion force is marginally weaker than the connection force, but still significant.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
* Calculations show shear force of two matching magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to IT equipment as well as medical implants. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field acts through matter and housings. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Magnetic elements are delicate – a violent impact against metal risks their cracking. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can cause material chips or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when handling with large magnets.

Rust risk: 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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Caution: On a vertical surface, the magnet holds merely ~20% of its nominal pull.

2. Steel saturation

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

3. Thermal stability

*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) = 0.42

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.

This product is a very strong cylindrical magnet, composed of advanced NdFeB material, which, with dimensions of Ø38x12 mm, guarantees optimal power. This specific item is characterized by a tolerance of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 32.79 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 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 321.71 N with a weight of only 102.07 g, this rod 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., 38.1 mm) using epoxy glues. To ensure stability in automation, 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 frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø38x12), 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 38 mm and height 12 mm. The key parameter here is the lifting capacity amounting to approximately 32.79 kg (force ~321.71 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it 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 38 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.

Strengths and weaknesses of neodymium magnets.

Pros

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

They retain full power for almost 10 years – the loss is just ~1% (in theory),
They show high resistance to demagnetization induced by external disturbances,
Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
They feature high magnetic induction at the operating surface, making them more effective,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
Possibility of precise modeling and modifying to complex requirements,
Versatile presence in advanced technology sectors – they find application in data components, electric motors, advanced medical instruments, also complex engineering applications.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 extremely resistant to heat
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing nuts and complex shapes in magnets, we recommend using a housing - magnetic mount.
Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
Due to complex production process, their price is higher than average,

Lifting parameters

Best holding force of the magnet in ideal parameters – what contributes to it?

Breakaway force was determined for ideal contact conditions, taking into account:

with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
with a cross-section no less than 10 mm
with a plane perfectly flat
without the slightest insulating layer between the magnet and steel
under perpendicular application of breakaway force (90-degree angle)
at room temperature

Lifting capacity in practice – influencing factors

It is worth knowing that the magnet holding will differ subject to elements below, in order of importance:

Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material composition – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

H&S for magnets

Pacemakers

Warning for patients: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or request help to handle the magnets.

Do not give to children

Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets may result in them attracting across intestines, which constitutes a severe health hazard and requires urgent medical intervention.

Fragile material

NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.

Flammability

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

Magnetic interference

Navigation devices and smartphones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Nickel allergy

Studies show that nickel (the usual finish) is a potent allergen. If you have an allergy, avoid direct skin contact and select versions in plastic housing.

Safe distance

Do not bring magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.

Caution required

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Heat warning

Do not overheat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Bodily injuries

Risk of injury: The attraction force is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.

Warning! Learn more about risks in the article: Magnet Safety Guide.
