Pulling power drops sharply with every subsequent millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, veneer) significantly reduces the pull force. Magnetic products hold strongest at the point of direct contact; air break weakens the power. See how quickly the pull force plummet, when the magnet does not touch flatly to the steel surface. When calculating the arrangement, discard redundant distances.

The table below calculates the theoretical holding capacity required to start the slippage of the magnet down against a upright steel plate (assuming standard friction). This parameter is a function of the air gap between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 10x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.64 kg / 1.42 lbs 645.0 g / 6.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.43 kg / 0.95 lbs 430.0 g / 4.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 0.47 lbs 215.0 g / 2.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.08 kg / 2.37 lbs 1075.0 g / 10.5 N

When placing a holder on a vertical wall (e.g., a car body), it will only hold barely about 1/5 of its maximum pull force. Gravitational force and a low friction coefficient mean that holders slide down easier than they pop off the substrate. Planning a vertical fastening? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the element will slide down under a noticeably lighter weight. Using a rubber layer can drastically raise the stability.

12 mm	100%	2.15 kg / 4.74 lbs 2150.0 g / 21.1 N

A thin sheet is not enough to take in the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a thin surface, the magnetism will pass right through and the holding will be smaller. To squeeze full efficiency of this magnet's power, you require a sufficiently solid piece of steel. The saturation effect causes that on thin elements (e.g., thin profiles), the holder shows lower pull force. We advise picking the steel thickness based on the following data.

Classic neodymiums lose parameters past the thermal threshold. Protect against heat – heat can permanently destroy this product. As the temperature rises, the magnet's capacity temporarily lowers. Avoid using this magnet close to ovens higher than its safe range. Exceeding the critical threshold will cause permanent loss of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Flat 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 significantly greater distance than a magnet and sheet combination. The setup of two magnets generates a stronger field and a further horizon of action. Want to build a strong closure? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the pinch force is huge. The repulsion force is a bit weaker than the attraction, but still significant.
*Field value for N-N configuration reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Important: Estimates show friction force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Hazards (electronics) - warnings
MW 10x3 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	4.5 cm

Extremely neodym field is a serious hazard to electronics as well as pacemakers. These neodymiums produce a field that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field passes through tissues and plastic. Special caution must be taken by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are delicate – a violent impact against metal risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can cause material chips or dangerous crushing to fingers. Always hold the magnet during bringing near metal 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 neodymium. Wear safety glasses when playing with powerful specimens.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Temperature resistance

*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) = 0.40

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 presented product is an extremely powerful cylinder magnet, produced from durable NdFeB material, which, with dimensions of Ø10x3 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 magnetic rod with significant force (approx. 2.15 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 21.04 N with a weight of only 1.77 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

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, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are suitable for 90% of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø10x3), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 3 mm. The value of 21.04 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.77 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 3 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 through the diameter if your project requires it.

Pros as well as cons of rare earth magnets.

Pros

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

They retain full power for around 10 years – the drop is just ~1% (according to analyses),
Magnets perfectly resist against demagnetization caused by external fields,
By using a smooth layer of nickel, the element gains an aesthetic look,
Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
Thanks to flexibility in shaping and the ability to modify to client solutions,
Key role in electronics industry – they serve a role in computer drives, brushless drives, diagnostic systems, as well as technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in miniature devices

Weaknesses

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
We recommend cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

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

Breakaway force was defined for the most favorable conditions, assuming:

with the use of a sheet made of special test steel, ensuring maximum field concentration
whose thickness reaches at least 10 mm
with a plane perfectly flat
under conditions of no distance (metal-to-metal)
for force acting at a right angle (in the magnet axis)
in temp. approx. 20°C

Practical aspects of lifting capacity – factors

Effective lifting capacity is affected by working environment parameters, such as (from priority):

Distance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Load vector – highest force is reached only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
Plate material – mild steel attracts best. Alloy admixtures reduce magnetic properties and lifting capacity.
Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

H&S for magnets

Keep away from electronics

Remember: neodymium magnets produce a field that disrupts precision electronics. Maintain a safe distance from your phone, device, and navigation systems.

Magnets are brittle

Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them cracking into shards.

Dust is flammable

Machining of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Health Danger

Individuals with a ICD have to maintain an safe separation from magnets. The magnetism can stop the functioning of the implant.

Nickel coating and allergies

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands and select versions in plastic housing.

Keep away from children

These products are not toys. Eating a few magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and requires immediate surgery.

Power loss in heat

Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.

Respect the power

Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their force.

Magnetic media

Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.

Finger safety

Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
