Grip strength drops significantly with every mm of distance. Note that every additional insulation layer (e.g., contamination, paint, rust) significantly reduces the pull force. Magnets work strongest in perfect adhesion; air break weakens the power. Analyze how quickly the load capacity plummet, when the product does not adhere flatly to the metal substrate. When calculating the mounting, avoid unnecessary gaps.

The table below calculates the theoretical weight limit necessary to cause the slippage of the magnet vertically along a vertical steel wall (considering standard friction). This value varies with the air gap between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 6x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.35 kg / 0.76 pounds 345.0 g / 3.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.23 kg / 0.51 pounds 230.0 g / 2.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.11 kg / 0.25 pounds 115.0 g / 1.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.58 kg / 1.27 pounds 575.0 g / 5.6 N

When hanging a element on a vertical surface (e.g., a board), it will maintain barely about 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip influence the fact that holders slip easier than they pop off the substrate. Want to create a hanger? Consider that the sliding force is much weaker than the maximum static pull force. On a painted metal, the magnet will slide down under a significantly smaller cargo. Using a rubber coating can significantly raise the stability.

2 mm	50%	0.58 kg / 1.27 pounds 575.0 g / 5.6 N
3 mm	75%	0.86 kg / 1.90 pounds 862.5 g / 8.5 N

12 mm	100%	1.15 kg / 2.54 pounds 1150.0 g / 11.3 N

A thin sheet is unable to absorb the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To achieve full efficiency of this neodymium's power, you require a sufficiently solid element of metal. The material oversaturation means that on delicate walls (e.g., appliance housings), the product holds weaker. We suggest choosing the steel dimension based on the following data.

Table 5: Working in heat (material behavior) - thermal limit

100 °C	-28.8%	0.82 kg / 1.81 pounds 818.8 g / 8.0 N

Standard neodymium magnets change their properties power past the thermal threshold. Watch out for overheating – heat can irreversibly destroy this magnet. With increasing heat, the neodymium's force momentarily lowers. Avoid using this magnet near heat sources higher than its safe range. Too high temperature will lead to permanent loss of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) risk losing magnetic properties at lower temperatures than taller cylinders. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a much further distance than a magnet and sheet setup. Such a system of magnet-to-magnet generates a stronger field and a larger range of operation. Planning to create a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the collision energy is massive. The repulsion force is a bit weaker than the connection force, but still significant.
*The magnetic induction for N-N configuration reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
* Estimates show friction force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Protective zones (implants) - warnings
MW 6x3 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	3.5 cm

A strong magnetic field is a large risk to electronic devices as well as pacemakers. These magnets generate a field that disrupts operation of digital equipment. Notice: the unseen radiation passes through tissues and plastic. Exceptional care must be exercised by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can cause material chips or painful pinches to fingers. Always hold the magnet during installation so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the magnet. Use safety goggles when handling with powerful specimens.

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Note: On a vertical surface, the magnet holds merely ~20% of its perpendicular strength.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) drastically reduces the holding force.

3. Power loss vs temp

*For N38 material, 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) = 0.59

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 offered product is an extremely powerful rod magnet, made from modern NdFeB material, which, at dimensions of Ø6x3 mm, guarantees maximum efficiency. The MW 6x3 / N38 model is characterized by high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 1.15 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 11.23 N with a weight of only 0.64 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 6.1 mm) using epoxy glues. To ensure long-term durability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are strong enough for the majority 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 (Ø6x3), 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 Ø6x3 mm, which, at a weight of 0.64 g, makes it an element with impressive magnetic energy density. The value of 11.23 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.64 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.

Strengths and weaknesses of neodymium magnets.

Benefits

Apart from their superior magnetism, neodymium magnets have these key benefits:

They do not lose magnetism, even over approximately 10 years – the decrease in strength is only ~1% (theoretically),
They retain their magnetic properties even under external field action,
By covering with a lustrous layer of gold, the element has an professional look,
Magnets are distinguished by extremely high magnetic induction on the outer side,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of exact modeling and optimizing to atypical needs,
Huge importance in advanced technology sectors – they are commonly used in data components, electric motors, medical devices, as well as modern systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Limitations

What to avoid - cons of neodymium magnets and ways of using them

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power 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
Due to limitations in realizing nuts and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical after entering the body.
With large orders the cost of neodymium magnets is a challenge,

Pull force analysis

Best holding force of the magnet in ideal parameters – what it depends on?

The specified lifting capacity represents the maximum value, recorded under laboratory conditions, namely:

with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
with a cross-section no less than 10 mm
with a plane perfectly flat
without the slightest clearance between the magnet and steel
for force acting at a right angle (pull-off, not shear)
at temperature room level

Practical aspects of lifting capacity – factors

Bear in mind that the magnet holding will differ subject to elements below, in order of importance:

Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped to the other side.
Steel type – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and holding force.
Surface quality – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
Temperature – heating the magnet results in weakening of force. Check the thermal limit for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate lowers the holding force.

Safe handling of NdFeB magnets

Finger safety

Mind your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying anything in their path. Be careful!

Handling guide

Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

ICD Warning

For implant holders: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Threat to electronics

Do not bring magnets near a wallet, laptop, or TV. The magnetism can destroy these devices and erase data from cards.

Dust explosion hazard

Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Impact on smartphones

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

Skin irritation risks

It is widely known that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, refrain from direct skin contact or choose encased magnets.

Adults only

Always store magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are tragic.

Fragile material

Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Thermal limits

Avoid heat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
