Grip strength decreases significantly per each millimeter of gap. Note that even a microscopic distance (e.g., dirt, varnish, dust) significantly diminishes the holding power. Magnetic products work strongest at the point of direct contact; gap drastically cuts the power. Observe how rapidly the parameters drop, when the magnet does not touch flatly to the metal substrate. When planning the arrangement, eliminate unnecessary gaps.

The following data defines the approximate shear load sufficient to start the downward movement of the magnet downwards on a upright steel plate (assuming standard friction). The holding force is relative to the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 4x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.14 kg / 0.30 pounds 138.0 g / 1.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 pounds 92.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 pounds 46.0 g / 0.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.51 pounds 230.0 g / 2.3 N

When hanging a element on a upright plane (e.g., a board), it will maintain just approx. 1/5 of its maximum pull force. Gravitational force and a weak degree of grip mean that products move down easier than they detach. Designing a wall mount? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a noticeably lighter load. Using a rubber layer can drastically improve the result.

2 mm	50%	0.23 kg / 0.51 pounds 230.0 g / 2.3 N
3 mm	75%	0.35 kg / 0.76 pounds 345.0 g / 3.4 N
5 mm	100%	0.46 kg / 1.01 pounds 460.0 g / 4.5 N
10 mm	100%	0.46 kg / 1.01 pounds 460.0 g / 4.5 N

12 mm	100%	0.46 kg / 1.01 pounds 460.0 g / 4.5 N

A thin sheet is incapable of conduct the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's potential, you need a suitably thick piece of metal. The saturation effect causes that on delicate walls (e.g., car bodies), the magnet holds weaker. We advise picking the steel cross-section according to the table below.

Ordinary NdFeB products change their properties power past the thermal threshold. Watch out for overheating – excessive heat can permanently demagnetize this product. With increasing heat, the magnet's capacity temporarily decreases. Avoid using this magnet close to heaters higher than its working range. Ignoring the limit will lead to permanent loss of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) may lose charge permanently at lower temperatures compared to rod magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a magnet and steel combination. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of action. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the impact force is huge. The repulsion force is slightly lower than the connection force, but still significant.
*Field value between like poles reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Note: Results refer to sliding force of two same neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to electronic devices as well as medical implants. These magnets produce a field that disrupts operation of digital equipment. Remember: the unseen radiation passes through tissues and plastic. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when handling with powerful specimens.

Corrosion warning: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

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

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC 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) = 1.00

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 a very strong rod magnet, manufactured from durable NdFeB material, which, with dimensions of Ø4x5 mm, guarantees the highest energy density. This specific item features high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.46 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 4.48 N with a weight of only 0.47 g, this rod 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., 4.1 mm) using epoxy glues. To ensure stability 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 frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need even stronger magnets in the same volume (Ø4x5), 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 4 mm and height 5 mm. The key parameter here is the holding force amounting to approximately 0.46 kg (force ~4.48 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against oxidation, 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 4 mm. Such an arrangement is most desirable 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 diametrically if your project requires it.

Strengths as well as weaknesses of rare earth magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

Their power remains stable, and after around 10 years it drops only by ~1% (according to research),
They do not lose their magnetic properties even under external field action,
A magnet with a smooth silver surface has better aesthetics,
Magnets are distinguished by impressive magnetic induction on the surface,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of accurate machining as well as adjusting to defined applications,
Fundamental importance in advanced technology sectors – they find application in hard drives, drive modules, medical devices, as well as other advanced devices.
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 recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 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, when using outdoors
Due to limitations in producing nuts and complicated shapes in magnets, we recommend using casing - magnetic mount.
Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

Highest magnetic holding force – what contributes to it?

Information about lifting capacity is the result of a measurement for the most favorable conditions, taking into account:

on a plate made of mild steel, optimally conducting the magnetic field
possessing a massiveness of min. 10 mm to ensure full flux closure
characterized by smoothness
with total lack of distance (no paint)
during detachment in a direction vertical to the plane
in neutral thermal conditions

Key elements affecting lifting force

Holding efficiency is affected by specific conditions, mainly (from most important):

Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
Thermal environment – temperature increase results in weakening of force. Check the thermal limit for a given model.

Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the holding force.

Safety rules for work with NdFeB magnets

Magnets are brittle

Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Health Danger

Warning for patients: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.

Precision electronics

Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.

Pinching danger

Danger of trauma: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Flammability

Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Cards and drives

Intense magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Sensitization to coating

Certain individuals have a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in dermatitis. We strongly advise use safety gloves.

Product not for children

Adult use only. Small elements pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.

Handling rules

Use magnets consciously. Their powerful strength can shock even professionals. Stay alert and respect their force.

Demagnetization risk

Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.

Caution! More info about hazards in the article: Magnet Safety Guide.
