Magnetic force weakens drastically per each millimeter of distance. Keep in mind that even the smallest gap (e.g., dirt, varnish, dust) strongly diminishes the holding power. Neodymiums hold most effectively in perfect adhesion; air break drastically cuts the power. Analyze how quickly the load capacity plummet, when the product does not touch flatly to the steel surface. When planning the mounting, eliminate unnecessary gaps.

This section shows the estimated holding capacity needed to initiate the sliding of the magnet vertically against a upright metal surface (considering typical friction coefficient). This parameter varies with the air gap between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MW 6x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.34 kg / 342.0 g 3.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.23 kg / 228.0 g 2.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.11 kg / 114.0 g 1.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.57 kg / 570.0 g 5.6 N

When mounting a element on a upright plane (e.g., a board), it you can count on only approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip cause that magnets slide down faster than they pull off. Planning a hanger? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a significantly smaller weight. Utilizing a rubberized pad can effectively raise the stability.

Table 4: Material efficiency (substrate influence) - power losses
MW 6x6 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.11 kg / 114.0 g 1.1 N
1 mm	25%	0.29 kg / 285.0 g 2.8 N
2 mm	50%	0.57 kg / 570.0 g 5.6 N
5 mm	100%	1.14 kg / 1140.0 g 11.2 N
10 mm	100%	1.14 kg / 1140.0 g 11.2 N

A too thin steel is not enough to focus the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a too thin substrate, the field will pass right through and the pull force will drop sharply. To utilize full efficiency of this magnet's potential, you require a sufficiently solid element of metal. The saturation phenomenon causes that on thin elements (e.g., car bodies), the holder holds weaker. We advise picking the steel thickness from these parameters.

Table 5: Thermal stability (material behavior) - power drop
MW 6x6 / N38

Ambient temp. (°C)	Power loss	Remaining pull	Status
20 °C	0.0%	1.14 kg / 1140.0 g 11.2 N	OK
40 °C	-2.2%	1.11 kg / 1114.9 g 10.9 N	OK
60 °C	-4.4%	1.09 kg / 1089.8 g 10.7 N	OK
80 °C	-6.6%	1.06 kg / 1064.8 g 10.4 N
100 °C	-28.8%	0.81 kg / 811.7 g 8.0 N

Standard neodymium magnets change their properties strength past the thermal threshold. Protect against heat – heat can permanently destroy this product. As the temperature rises, the magnet's force briefly lowers. Avoid using this product in hot environments higher than its operating temperature limit. Ignoring the limit will lead to permanent loss of magnetic properties.

*Important note: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (pancake types) may lose charge permanently sooner compared to rod magnets. The danger warning in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a wider radius than a neodymium and metal setup. The setup of magnet-to-magnet generates a stronger field and a larger range of performance. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is huge. The repulsion force is slightly lower than the attraction, but still impressive.
*Field value between like poles drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).

A strong magnetic field poses a large risk to electronics and pacemakers. These magnets generate a field that prevents correct functioning of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and glass. Exceptional care must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the magnet. Wear eye protection when handling 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.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Note: On a vertical surface, the magnet retains merely a fraction of its nominal pull.

2. Steel saturation

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

3. Heat tolerance

*For standard magnets, the safety limit is 80°C.

The presented product is a very strong rod magnet, manufactured from durable NdFeB material, which, with dimensions of Ø6x6 mm, guarantees optimal power. This specific item boasts high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 1.14 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures 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 fastening or actuating element. Thanks to the high power of 11.18 N with a weight of only 1.27 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular 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 (Ø6x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 6 mm and height 6 mm. The key parameter here is the lifting capacity amounting to approximately 1.14 kg (force ~11.18 N), which, with such compact 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 6 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.

Advantages and disadvantages of rare earth magnets.

Pros

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

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
Neodymium magnets remain extremely resistant to loss of magnetic properties caused by magnetic disturbances,
Thanks to the elegant finish, the layer of nickel, gold, or silver gives an modern appearance,
Magnetic induction on the working part of the magnet is exceptional,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
Thanks to versatility in constructing and the ability to adapt to client solutions,
Significant place in electronics industry – they serve a role in mass storage devices, motor assemblies, advanced medical instruments, and complex engineering applications.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
When exposed to high temperature, neodymium magnets experience a drop in strength. 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
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Limited ability of making threads in the magnet and complex forms - recommended is a housing - mounting mechanism.
Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what it depends on?

Breakaway force is the result of a measurement for the most favorable conditions, assuming:

on a base made of mild steel, effectively closing the magnetic flux
possessing a massiveness of at least 10 mm to avoid saturation
with an ideally smooth touching surface
under conditions of no distance (surface-to-surface)
under axial force direction (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

Please note that the application force will differ subject to the following factors, starting with the most relevant:

Air gap (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.

Safe handling of NdFeB magnets

Machining danger

Dust produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Powerful field

Use magnets consciously. Their immense force can surprise even experienced users. Be vigilant and respect their power.

Electronic devices

Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Sensitization to coating

Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness happens, immediately stop working with magnets and wear gloves.

Magnetic interference

A strong magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to prevent damaging the sensors.

Bodily injuries

Danger of trauma: The pulling power is so immense that it can cause hematomas, pinching, and broken bones. Use thick gloves.

Magnet fragility

NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets will cause them breaking into small pieces.

Permanent damage

Do not overheat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, inquire about HT versions (H, SH, UH).

Pacemakers

Patients with a ICD have to maintain an absolute distance from magnets. The magnetic field can stop the functioning of the life-saving device.

Keep away from children

These products are not toys. Swallowing multiple magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
