Grip strength decreases drastically with every subsequent millimeter of spacing. Keep in mind that every additional insulation layer (e.g., contamination, paint, veneer) noticeably weakens the grip. Magnetic products work strongest at the point of direct contact; gap weakens the force. Analyze how flashily the load capacity plummet, when the magnet does not touch flatly to the metal substrate. When calculating the arrangement, avoid redundant distances.

The following data presents the theoretical weight limit sufficient to cause the sliding of the magnet vertically along a vertical steel plate (assuming typical friction coefficient). The holding force is a function of the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces

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

When mounting a holder on a vertical surface (e.g., a board), it will only hold only about 20%-30% of nominal attraction strength. Gravitational force as well as a weak degree of grip mean that holders slip faster than they pop off the substrate. Designing a wall mount? Note that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the holder will slip down under a noticeably lighter cargo. Application of an anti-slip pad can effectively increase the grip.

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

A thin metal plate is not enough to focus the entire magnetic field, which weakens actual performance of the holder. If you mount a strong magnet to a thin surface, the field will pass right through and the holding will be smaller. To utilize full efficiency of this magnet's potential, you require a sufficiently solid backing of metal. The saturation effect causes that on thin elements (e.g., car bodies), the holder works worse. We advise picking the steel thickness from these parameters.

Ordinary NdFeB products change their properties parameters after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly demagnetize this magnet. With every degree above norm, the neodymium's power temporarily decreases. Avoid using this magnet in hot environments higher than its working range. Ignoring the limit will lead to irreversible degradation of magnetism.

*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures than taller cylinders. Warning indicator in the table signals permanent field degradation for this particular item.

Two magnetic products interact from a significantly greater distance than a magnet and sheet combination. The setup of two magnets creates a more powerful interaction and a larger range of operation. Want to build a solid fastener? Apply two magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is extreme. The levitation is a bit weaker than the connection force, but still impressive.
*Flux density between like poles reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Estimates show shear force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a real danger to IT equipment and medical implants. These magnets generate a flux that prevents correct functioning of digital equipment. Remember: the unseen radiation penetrates the body and plastic. Exceptional care must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - collision effects
MW 6x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	42.77 km/h (11.88 m/s)	0.05 J
30 mm	74.05 km/h (20.57 m/s)	0.14 J
50 mm	95.59 km/h (26.55 m/s)	0.23 J
100 mm	135.19 km/h (37.55 m/s)	0.45 J

Neodymium magnets are delicate – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the neodymium. Use safety goggles when playing with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet holds merely approx. 20-30% of its max power.

2. Plate thickness effect

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

3. Heat tolerance

*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 presented product is an extremely powerful cylindrical magnet, composed of advanced NdFeB material, which, at dimensions of Ø6x3 mm, guarantees the highest energy density. The MW 6x3 / N38 model boasts an accuracy of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 1.15 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building generators, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power 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.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen 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 (Ø6x3), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 6 mm and height 3 mm. The key parameter here is the holding force amounting to approximately 1.15 kg (force ~11.23 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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. 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.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:

Their strength remains stable, and after approximately ten years it drops only by ~1% (theoretically),
They maintain their magnetic properties even under external field action,
Thanks to the metallic finish, the layer of nickel, gold, or silver-plated gives an visually attractive appearance,
They show high magnetic induction at the operating surface, which improves attraction properties,
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 accurate creating and adapting to individual requirements,
Versatile presence in modern industrial fields – they are commonly used in computer drives, electromotive mechanisms, medical equipment, and industrial machines.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We recommend cover - magnetic holder, due to difficulties in creating threads inside the magnet and complicated shapes.
Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical when they are in the body.
With mass production the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum holding power of the magnet – what contributes to it?

Magnet power was defined for ideal contact conditions, taking into account:

with the use of a sheet made of special test steel, guaranteeing maximum field concentration
possessing a thickness of minimum 10 mm to ensure full flux closure
characterized by lack of roughness
without any air gap between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at ambient temperature room level

Impact of factors on magnetic holding capacity in practice

In practice, the actual holding force is determined by a number of factors, listed from the most important:

Air gap (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or debris).
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
Base massiveness – insufficiently thick steel does not close the flux, causing part of the flux to be escaped to the other side.
Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
Surface finish – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity was measured with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the holding force.

Safety rules for work with neodymium magnets

Do not give to children

Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Store away from kids and pets.

Cards and drives

Data protection: Neodymium magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Flammability

Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.

Handling rules

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Warning for allergy sufferers

Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness happens, immediately stop working with magnets and wear gloves.

Life threat

Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Bone fractures

Danger of trauma: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.

Magnet fragility

Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Heat warning

Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.

Phone sensors

Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your phone, device, and navigation systems.
