Magnetic force drops sharply with every subsequent millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, veneer) strongly diminishes the holding power. Magnets work most effectively in perfect adhesion; gap drastically cuts the force. Observe how flashily the load capacity drop, when the product does not adhere directly to the steel surface. When calculating the mounting, eliminate additional spacers.

The table below presents the theoretical weight limit sufficient to initiate the sliding of the magnet vertically against a vertical steel plate (assuming typical friction coefficient). This parameter depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 3x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.06 kg / 0.13 pounds 60.0 g / 0.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.04 kg / 0.09 pounds 40.0 g / 0.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.02 kg / 0.04 pounds 20.0 g / 0.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.10 kg / 0.22 pounds 100.0 g / 1.0 N

When placing a magnet on a upright wall (e.g., a fridge), it you can count on only approx. 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip influence the fact that products slip faster than they pull off. Designing a wall mount? Remember that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slip down under a noticeably lighter weight. Using a rubber pad can drastically improve the result.

MW 3x6 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.02 kg / 0.04 pounds 20.0 g / 0.2 N

2 mm	50%	0.10 kg / 0.22 pounds 100.0 g / 1.0 N
3 mm	75%	0.15 kg / 0.33 pounds 150.0 g / 1.5 N
5 mm	100%	0.20 kg / 0.44 pounds 200.0 g / 2.0 N
10 mm	100%	0.20 kg / 0.44 pounds 200.0 g / 2.0 N
11 mm	100%	0.20 kg / 0.44 pounds 200.0 g / 2.0 N
12 mm	100%	0.20 kg / 0.44 pounds 200.0 g / 2.0 N

A too thin steel is incapable of take in the entire magnetic field, which weakens actual performance of the magnet. Should you attach a powerful product to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To utilize full efficiency of this neodymium's power, you require a sufficiently solid piece of steel. The material oversaturation means that on delicate walls (e.g., thin profiles), the holder shows lower pull force. We advise picking the steel dimension according to the table below.

Table 5: Thermal stability (material behavior) - resistance threshold
MW 3x6 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	0.20 kg / 0.44 pounds 200.0 g / 2.0 N	OK
40 °C	-2.2%	0.20 kg / 0.43 pounds 195.6 g / 1.9 N	OK
60 °C	-4.4%	0.19 kg / 0.42 pounds 191.2 g / 1.9 N	OK
80 °C	-6.6%	0.19 kg / 0.41 pounds 186.8 g / 1.8 N
100 °C	-28.8%	0.14 kg / 0.31 pounds 142.4 g / 1.4 N

Standard neodymium magnets change their properties power above the temperature limit. Watch out for overheating – high temperature can irreversibly damage this product. With increasing heat, the magnet's capacity briefly drops. Avoid using this magnet near heat sources exceeding its working range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization sooner than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a wider radius than a magnet and steel setup. The setup of two magnets creates a more powerful interaction and a larger range of operation. Want to build a powerful holder? Use a pair of magnets instead of one magnet and a steel. Remember that when bringing together two magnets, the pinch force is huge. The levitation is slightly lower than the attraction, but still significant.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
* Estimates demonstrate sliding force of two identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - precautionary measures
MW 3x6 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	2.5 cm
Hearing aid	10 Gs (1.0 mT)	2.0 cm
Mechanical watch	20 Gs (2.0 mT)	1.5 cm

A strong magnetic field poses a real danger to IT equipment and pacemakers. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field acts through matter and glass. Special caution must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - collision effects
MW 3x6 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	25.21 km/h (7.00 m/s)	0.01 J
30 mm	43.67 km/h (12.13 m/s)	0.02 J
50 mm	56.38 km/h (15.66 m/s)	0.04 J
100 mm	79.73 km/h (22.15 m/s)	0.08 J

Magnetic elements are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Kinetic force can cause material chips or injury to skin. Be sure to control the product during installation so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the magnet. Wear safety glasses when handling 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. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet retains only approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

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

3. Temperature resistance

*For N38 material, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.21

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 extremely powerful rod magnet, produced from advanced NdFeB material, which, with dimensions of Ø3x6 mm, guarantees optimal power. This specific item boasts 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. 0.20 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 1.95 N with a weight of only 0.32 g, this rod is indispensable in electronics and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need even stronger magnets in the same volume (Ø3x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø3x6 mm, which, at a weight of 0.32 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 0.20 kg (force ~1.95 N), which, with such defined 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.

This rod magnet is magnetized axially (along the height of 6 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized through the diameter if your project requires it.

Pros as well as cons of neodymium magnets.

Strengths

Apart from their consistent magnetic energy, neodymium magnets have these key benefits:

They have stable power, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
They are noted for resistance to demagnetization induced by external magnetic fields,
The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnetic induction on the top side of the magnet remains impressive,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to the potential of accurate forming and adaptation to individualized projects, neodymium magnets can be created in a broad palette of geometric configurations, which amplifies use scope,
Fundamental importance in advanced technology sectors – they serve a role in computer drives, brushless drives, advanced medical instruments, as well as multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Weaknesses

Problematic aspects of neodymium magnets and proposals for their use:

Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Limited ability of creating threads in the magnet and complex forms - preferred is casing - mounting mechanism.
Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets can 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 hinders application in large quantities

Pull force analysis

Magnetic strength at its maximum – what affects it?

The force parameter is a result of laboratory testing conducted under specific, ideal conditions:

using a plate made of low-carbon steel, serving as a ideal flux conductor
with a cross-section no less than 10 mm
characterized by lack of roughness
with total lack of distance (without impurities)
for force acting at a right angle (in the magnet axis)
in neutral thermal conditions

Magnet lifting force in use – key factors

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

Distance (between the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
Base massiveness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped into the air.
Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets

Product not for children

Always keep magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.

Fragile material

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.

Avoid contact if allergic

A percentage of the population suffer from a sensitization to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact may cause an allergic reaction. We recommend use protective gloves.

Implant safety

Patients with a ICD should keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Phone sensors

An intense magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Maintain magnets close to a smartphone to prevent damaging the sensors.

Demagnetization risk

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

Dust is flammable

Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.

Powerful field

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.

Finger safety

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

Protect data

Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
