Pulling power drops sharply with every mm of gap. Keep in mind that even the smallest gap (e.g., contamination, varnish, veneer) strongly reduces the pull force. Neodymiums operate strongest in perfect adhesion; gap nullifies the force. Analyze how quickly the pull force plummet, when the magnet does not adhere directly to the metal substrate. When planning the assembly, eliminate additional spacers.

This section shows the approximate holding capacity necessary to start the slippage of the magnet downwards along a upright metal surface (considering standard friction). The holding force varies with the separation distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 4x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.11 kg / 0.23 lbs 105.0 g / 1.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.07 kg / 0.15 lbs 70.0 g / 0.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.03 kg / 0.08 lbs 35.0 g / 0.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.18 kg / 0.39 lbs 175.0 g / 1.7 N

When mounting a element on a upright wall (e.g., a board), it will only hold barely about 1/5 of its maximum pull force. Gravitational force and a weak degree of grip influence the fact that products slide down easier than they pop off the substrate. Planning a hanger? Remember that the shear force is much weaker than the maximum static pull force. On a smooth steel, the magnet will give way down under a significantly smaller load. Application of an anti-slip layer can drastically raise the stability.

Table 4: Steel thickness (saturation) - power losses
MW 4x8 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)

2 mm	50%	0.18 kg / 0.39 lbs 175.0 g / 1.7 N
3 mm	75%	0.26 kg / 0.58 lbs 262.5 g / 2.6 N
5 mm	100%	0.35 kg / 0.77 lbs 350.0 g / 3.4 N
10 mm	100%	0.35 kg / 0.77 lbs 350.0 g / 3.4 N
11 mm	100%	0.35 kg / 0.77 lbs 350.0 g / 3.4 N
12 mm	100%	0.35 kg / 0.77 lbs 350.0 g / 3.4 N

A thin metal plate is not enough to focus the entire magnetic field, which squanders power of the holder. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze 100% of this neodymium's power, you need a suitably thick piece of metal. The saturation effect causes that on sheet metal structures (e.g., car bodies), the magnet works worse. We advise picking the steel thickness from these parameters.

Table 5: Working in heat (stability) - resistance threshold
MW 4x8 / N38

20 °C	0.0%	0.35 kg / 0.77 lbs 350.0 g / 3.4 N	OK
40 °C	-2.2%	0.34 kg / 0.75 lbs 342.3 g / 3.4 N	OK

Ordinary NdFeB products irreversibly lose power past the thermal threshold. Protect against heat – heat can irreversibly damage this magnet. As the temperature rises, the neodymium's power temporarily drops. Do not use this magnet in hot environments higher than its safe range. Exceeding the critical threshold will result in permanent loss of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a wider radius than a neodymium and metal setup. The setup of two magnets produces a massive flux and a further horizon of performance. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is massive. The repulsion force is a bit weaker than the attraction, but still impressive.
*The magnetic induction in repulsion mode drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
* Calculations refer to sliding force of dual same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a serious hazard to IT equipment and medical implants. These NdFeB products produce a flux that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation acts through matter and glass. Special caution must be taken by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, car keys, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - collision effects

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	21.79 km/h (6.05 m/s)	0.01 J

100 mm	68.89 km/h (19.14 m/s)	0.14 J

Magnetic elements are very brittle – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when working with large magnets.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet retains only a fraction of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Thermal stability

*For N38 grade, the safety 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.

This product is an exceptionally strong rod magnet, made from advanced NdFeB material, which, at dimensions of Ø4x8 mm, guarantees maximum efficiency. The MW 4x8 / N38 model features high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 0.35 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building generators, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 3.48 N with a weight of only 0.75 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 two-component epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability 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 (Ø4x8), 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 4 mm and height 8 mm. The value of 3.48 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.75 g. 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 4 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 and weaknesses of rare earth magnets.

Pros

Apart from their strong holding force, neodymium magnets have these key benefits:

They do not lose strength, even after approximately ten years – the drop in lifting capacity is only ~1% (according to tests),
Neodymium magnets are characterized by exceptionally resistant to loss of magnetic properties caused by magnetic disturbances,
Thanks to the shiny finish, the plating of nickel, gold-plated, or silver-plated gives an elegant appearance,
The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of custom shaping and modifying to atypical applications,
Wide application in electronics industry – they serve a role in HDD drives, electromotive mechanisms, advanced medical instruments, as well as other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets: tips and applications.

At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing threads and complex forms in magnets, we recommend using a housing - magnetic mechanism.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Highest magnetic holding force – what affects it?

The force parameter is a theoretical maximum value performed under specific, ideal conditions:

on a plate made of structural steel, optimally conducting the magnetic flux
whose thickness is min. 10 mm
with a surface cleaned and smooth
with total lack of distance (no paint)
under vertical application of breakaway force (90-degree angle)
at temperature approx. 20 degrees Celsius

Impact of factors on magnetic holding capacity in practice

Bear in mind that the application force will differ depending on elements below, in order of importance:

Clearance – existence of any layer (rust, dirt, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and lifting capacity.
Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Temperature influence – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

H&S for magnets

Skin irritation risks

A percentage of the population have a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Frequent touching might lead to an allergic reaction. We recommend use protective gloves.

Protect data

Avoid bringing magnets close to a wallet, computer, or screen. The magnetic field can destroy these devices and erase data from cards.

Health Danger

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

Heat warning

Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and strength.

Compass and GPS

Be aware: rare earth magnets produce a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and GPS.

Conscious usage

Handle magnets consciously. Their huge power can shock even professionals. Be vigilant and respect their power.

Product not for children

Neodymium magnets are not intended for children. Eating a few magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.

Protective goggles

Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them breaking into small pieces.

Do not drill into magnets

Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Crushing force

Danger of trauma: The attraction force is so immense that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.

Danger! Learn more about risks in the article: Safety of working with magnets.
