Pulling power weakens drastically per each millimeter of gap. Keep in mind that even a very thin break (e.g., dirt, varnish, dust) significantly diminishes the holding power. Magnetic products operate most effectively at the point of direct contact; distance drastically cuts the power. See how quickly the parameters plummet, when the magnet does not touch tightly to the steel surface. When calculating the arrangement, discard redundant distances.

The following data indicates the theoretical force required to start the shifting of the magnet downwards on a vertical metal surface (considering standard friction). This parameter is a function of the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 8x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.22 kg / 0.49 pounds 222.0 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 pounds 148.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.16 pounds 74.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.37 kg / 0.82 pounds 370.0 g / 3.6 N

When hanging a magnet on a upright plane (e.g., a board), it will maintain only about 1/5 of its nominal power. Gravitational force and a weak degree of grip cause that products slip easier than they pop off the substrate. Planning a vertical fastening? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a much lighter load. Utilizing a rubberized coating can effectively increase the grip.

12 mm	100%	0.74 kg / 1.63 pounds 740.0 g / 7.3 N

A thin sheet is not enough to take in the full magnetic flux, which wastes potential of the magnet. Should you install a neodymium to a too thin substrate, the magnetism will pass right through and the pull force will drop sharply. To utilize 100% of this magnet's power, you require a sufficiently solid backing of metal. The material oversaturation means that on delicate walls (e.g., appliance housings), the product holds weaker. We recommend selecting the steel dimension from these parameters.

Ordinary NdFeB products lose power above the temperature limit. Protect against heat – heat can permanently damage this product. With every degree above norm, the magnet's power temporarily lowers. Avoid using this product near heat sources higher than its operating temperature limit. Exceeding the critical threshold will lead to destruction of magnetism.

*Technical advisory: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures than taller cylinders. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel setup. The setup of magnet-to-magnet generates a stronger field and a wider radius of action. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is massive. The levitation is a bit weaker than the attraction, but still impressive.
*Flux density between like poles reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Figures show friction force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronics and pacemakers. These NdFeB products produce a field that disrupts operation of sensitive medical devices. Be aware: the unseen radiation passes through tissues and plastic. Increased vigilance must be taken by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose speeds with massive force. Impact energy can trigger coating fragments or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the neodymium. Use safety goggles when working 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!

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

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains merely ~20% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Thermal stability

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.27

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 an extremely powerful rod magnet, produced from durable NdFeB material, which, with dimensions of Ø8x1.5 mm, guarantees the highest energy density. This specific item is characterized by high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 0.74 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing 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 high power of 7.27 N with a weight of only 0.57 g, this rod is indispensable in electronics and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure long-term durability in industry, anaerobic resins 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 high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø8x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 8 mm and height 1.5 mm. The key parameter here is the lifting capacity amounting to approximately 0.74 kg (force ~7.27 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.

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 8 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 through the diameter if your project requires it.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Besides their tremendous field intensity, neodymium magnets offer the following advantages:

They do not lose strength, even over around 10 years – the decrease in power is only ~1% (theoretically),
They retain their magnetic properties even under external field action,
A magnet with a shiny silver surface looks better,
The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
Thanks to freedom in constructing and the capacity to modify to complex applications,
Wide application in modern technologies – they are utilized in mass storage devices, electric motors, medical devices, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in miniature devices

Limitations

Cons of neodymium magnets: application proposals

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing threads and complicated forms in magnets, we recommend using a housing - magnetic holder.
Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Maximum holding power of the magnet – what contributes to it?

The lifting capacity listed is a theoretical maximum value conducted under the following configuration:

on a base made of structural steel, effectively closing the magnetic flux
whose thickness is min. 10 mm
with a plane cleaned and smooth
under conditions of ideal adhesion (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
in neutral thermal conditions

Practical lifting capacity: influencing factors

Bear in mind that the application force may be lower influenced by elements below, starting with the most relevant:

Gap (betwixt the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Safety rules for work with neodymium magnets

Magnetic media

Device Safety: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Material brittleness

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets will cause them cracking into small pieces.

Immense force

Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.

Fire risk

Powder generated during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.

Metal Allergy

Studies show that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, refrain from direct skin contact and choose versions in plastic housing.

Product not for children

Absolutely keep magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are tragic.

Keep away from electronics

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

Maximum temperature

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

Medical interference

Warning for patients: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Bone fractures

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

Attention! More info about risks in the article: Magnet Safety Guide.
