Grip strength weakens significantly with every mm of spacing. Note that every additional insulation layer (e.g., contamination, varnish, rust) significantly reduces the pull force. Magnetic products hold most effectively during direct contact; distance weakens the power. Notice how quickly the parameters drop, when the product does not adhere directly to the metal substrate. When planning the mounting, discard unnecessary gaps.

The table below indicates the theoretical force needed to initiate the sliding of the magnet downwards against a vertical steel plate (considering typical friction coefficient). This value varies with the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 8x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.65 kg / 1.44 pounds 651.0 g / 6.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.43 kg / 0.96 pounds 434.0 g / 4.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 0.48 pounds 217.0 g / 2.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.09 kg / 2.39 pounds 1085.0 g / 10.6 N

When mounting a magnet on a vertical wall (e.g., a car body), it will maintain barely approx. 1/5 of its nominal power. Gravitational force and a low friction coefficient influence the fact that products slip faster than they pop off the substrate. Planning a wall mount? Consider that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the element will give way down under a much lighter cargo. Application of an anti-slip pad can effectively increase the grip.

2 mm	50%	1.09 kg / 2.39 pounds 1085.0 g / 10.6 N

11 mm	100%	2.17 kg / 4.78 pounds 2170.0 g / 21.3 N
12 mm	100%	2.17 kg / 4.78 pounds 2170.0 g / 21.3 N

A thin metal plate is incapable of take in the entire magnetic field, which weakens actual performance of the holder. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To utilize 100% of this neodymium's potential, you need a suitably thick piece of metal. The saturation phenomenon causes that on thin elements (e.g., car bodies), the product holds weaker. We suggest choosing the steel thickness based on the following data.

Classic neodymiums lose power past the thermal threshold. Protect against heat – high temperature can permanently destroy this magnet. As the temperature rises, the neodymium's force temporarily decreases. Avoid using this product near heat sources exceeding its operating temperature limit. Ignoring the limit will lead to irreversible degradation of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) are more susceptible to demagnetization sooner than taller cylinders. Red status in the table signals permanent field degradation for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and steel setup. Such a system of two magnets creates a more powerful interaction and a larger range of operation. Designing a solid fastener? Apply two magnets instead of a neodymium and a steel. Remember that when bringing together two magnets, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still impressive.
*Field value in repulsion mode drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Figures apply to friction force of a pair of identical magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a large risk to electronics as well as medical implants. These neodymiums produce a flux that destroys function of sensitive medical devices. Notice: the unseen radiation passes through tissues and glass. Special caution must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Impact energy can destroy the magnet or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear safety glasses when handling with large magnets.

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

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

1. Wall mount (shear)

*Note: On a vertical wall, the magnet retains just approx. 20-30% of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) severely limits 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) = 0.68

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 exceptionally strong rod magnet, composed of advanced NdFeB material, which, at dimensions of Ø8x5 mm, guarantees optimal power. The MW 8x5 / N38 model boasts high dimensional repeatability and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 2.17 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 21.31 N with a weight of only 1.88 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, 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 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 (Ø8x5), 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 8 mm and height 5 mm. The value of 21.31 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.88 g. 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 8 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.

Pros as well as cons of neodymium magnets.

Strengths

Besides their tremendous pulling force, neodymium magnets offer the following advantages:

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
Neodymium magnets remain highly resistant to loss of magnetic properties caused by external magnetic fields,
A magnet with a smooth nickel surface is more attractive,
Magnets possess exceptionally strong magnetic induction on the active area,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to flexibility in designing and the capacity to modify to complex applications,
Universal use in high-tech industry – they find application in hard drives, electric motors, precision medical tools, and industrial machines.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in producing threads and complex forms in magnets, we recommend using a housing - magnetic holder.
Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, small components of these magnets are able to complicate diagnosis medical when they are in the body.
With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what affects it?

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

on a block made of structural steel, effectively closing the magnetic flux
possessing a massiveness of at least 10 mm to ensure full flux closure
characterized by smoothness
under conditions of no distance (metal-to-metal)
under axial force vector (90-degree angle)
in neutral thermal conditions

Magnet lifting force in use – key factors

Holding efficiency is affected by working environment parameters, such as (from most important):

Clearance – existence of any layer (rust, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
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).
Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be escaped into the air.
Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.

Safe handling of NdFeB magnets

Magnetic media

Do not bring magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Crushing force

Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Product not for children

Adult use only. Tiny parts can be swallowed, leading to serious injuries. Keep out of reach of kids and pets.

Pacemakers

For implant holders: Powerful magnets affect electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.

Do not drill into magnets

Machining of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Sensitization to coating

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease handling magnets and use protective gear.

Magnets are brittle

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Phone sensors

An intense magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.

Heat sensitivity

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.

Handling rules

Use magnets consciously. Their powerful strength can surprise even professionals. Stay alert and respect their power.
