Pulling power weakens sharply with every subsequent millimeter of gap. Note that every additional insulation layer (e.g., dirt, paint, dust) noticeably weakens the grip. Magnetic products hold optimally in perfect adhesion; air break nullifies the power. Analyze how quickly the load capacity fall, when the magnet does not adhere directly to the metal substrate. When designing the mounting, discard unnecessary gaps.

The following data indicates the estimated weight limit sufficient to initiate the slippage of the magnet vertically along a vertical metal surface (assuming typical friction). This value depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MW 10x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.01 kg / 2.24 pounds 1014.0 g / 9.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.68 kg / 1.49 pounds 676.0 g / 6.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.34 kg / 0.75 pounds 338.0 g / 3.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.69 kg / 3.73 pounds 1690.0 g / 16.6 N

When placing a magnet on a vertical surface (e.g., a car body), it will maintain just approx. 1/5 of nominal attraction strength. Gravitational force as well as a low friction coefficient mean that products slip easier than they pop off the substrate. Planning a vertical fastening? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a significantly smaller load. Using a rubber layer can drastically raise the stability.

A thin metal plate is incapable of take in the full magnetic flux, which weakens actual performance of the magnet. Should you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze 100% of this neodymium's potential, you require a sufficiently solid backing of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the magnet works worse. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products change their properties parameters past the thermal threshold. Protect against heat – heat can irreversibly damage this magnet. With every degree above norm, the magnet's capacity temporarily lowers. Do not use this magnet close to ovens exceeding its operating temperature limit. Ignoring the limit will lead to destruction of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low Pc) may lose charge permanently under lower heat stress compared to rod magnets. Red status in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a much further distance than a magnet and sheet combination. The connection of two magnets generates a stronger field and a further horizon of performance. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the collision energy is huge. The repulsion force is a bit weaker than the connection force, but still impressive.
*Field value for N-N configuration drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Attention: Figures show friction force of dual identical magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a large risk to electronic devices as well as pacemakers. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and housings. Increased vigilance must be taken by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose becomes dangerous. Impact energy can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when playing with powerful specimens.

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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Note: On a vertical wall, the magnet holds merely a fraction of its perpendicular strength.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) significantly reduces 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) = 0.79

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.

The presented product is an exceptionally strong cylindrical magnet, manufactured from modern NdFeB material, which, at dimensions of Ø10x8 mm, guarantees the highest energy density. This specific item features high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 3.38 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 33.16 N with a weight of only 4.71 g, this rod is indispensable in miniature devices 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., 10.1 mm) using two-component 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.

Grade N38 is the most popular 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 (Ø10x8), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø10x8 mm, which, at a weight of 4.71 g, makes it an element with high magnetic energy density. The value of 33.16 N means that the magnet is capable of holding a weight many times exceeding its own mass of 4.71 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 8 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.

Advantages as well as disadvantages of rare earth magnets.

Strengths

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

They do not lose strength, even during nearly 10 years – the drop in strength is only ~1% (according to tests),
Magnets effectively resist against loss of magnetization caused by external fields,
In other words, due to the glossy layer of nickel, the element is aesthetically pleasing,
Magnetic induction on the working layer of the magnet is very high,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Thanks to flexibility in designing and the capacity to modify to unusual requirements,
Versatile presence in future technologies – they find application in HDD drives, motor assemblies, medical equipment, also other advanced devices.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Drawbacks and weaknesses of neodymium magnets: application proposals

At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complicated forms in magnets, we propose using a housing - magnetic holder.
Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small elements of these devices can be problematic in diagnostics medical in case of swallowing.
Due to neodymium price, their price is relatively high,

Lifting parameters

Detachment force of the magnet in optimal conditions – what contributes to it?

The force parameter is a measurement result executed under the following configuration:

using a base made of high-permeability steel, functioning as a circuit closing element
whose transverse dimension is min. 10 mm
with an polished contact surface
under conditions of no distance (metal-to-metal)
for force applied at a right angle (pull-off, not shear)
in stable room temperature

Determinants of lifting force in real conditions

In real-world applications, the actual holding force depends on many variables, ranked from most significant:

Gap (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
Metal type – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
Operating temperature – neodymium magnets 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 was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Warnings

Impact on smartphones

Be aware: neodymium magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.

Protective goggles

Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.

Do not overheat magnets

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

Life threat

Individuals with a pacemaker should maintain an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.

Product not for children

Adult use only. Small elements can be swallowed, causing severe trauma. Store out of reach of children and animals.

Conscious usage

Use magnets consciously. Their huge power can shock even experienced users. Plan your moves and do not underestimate their power.

Finger safety

Large magnets can smash fingers in a fraction of a second. Do not put your hand between two strong magnets.

Nickel allergy

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, prevent touching magnets with bare hands or choose versions in plastic housing.

Protect data

Data protection: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).

Fire warning

Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
