Magnetic force decreases drastically per each millimeter of spacing. Note that even a very thin break (e.g., contamination, paint, rust) strongly diminishes the holding power. Magnetic products work most effectively during direct contact; distance drastically cuts the power. Observe how rapidly the pull force fall, when the product does not adhere directly to the steel surface. When designing the arrangement, discard additional spacers.

The table below shows the approximate shear load necessary to initiate the shifting of the magnet downwards along a vertical metal surface (considering standard friction coefficient). This value varies with the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 16x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.33 kg / 2.93 LBS 1329.0 g / 13.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.89 kg / 1.95 LBS 886.0 g / 8.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.44 kg / 0.98 LBS 443.0 g / 4.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.22 kg / 4.88 LBS 2215.0 g / 21.7 N

When placing a magnet on a vertical wall (e.g., a fridge), it you can count on barely approx. 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip influence the fact that products move down faster than they detach. Want to create a vertical fastening? Remember that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the element will slide down under a noticeably lighter weight. Using a rubber layer can effectively increase the grip.

A thin sheet is unable to take in the entire magnetic field, which wastes potential of the holder. Should you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the holding will be smaller. To squeeze 100% of this neodymium's power, you require a sufficiently solid piece of metal. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel cross-section from these parameters.

Classic neodymiums lose strength past the thermal threshold. Protect against heat – heat can permanently demagnetize this product. As the temperature rises, the neodymium's capacity briefly lowers. Avoid using this product close to ovens higher than its safe range. Too high temperature will lead to permanent loss of magnetic properties.

*Technical advisory: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (low Pc) are more susceptible to demagnetization sooner than taller cylinders. Red status in the table points to permanent field degradation for this particular item.

Two magnets interact from a significantly greater distance than a magnet and sheet setup. The connection of magnet-to-magnet produces a massive flux and a further horizon of performance. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when connecting a pair of magnets, the collision energy is extreme. The repulsion force is slightly lower than the connection force, but still large.
*Flux density in repulsion mode drops to ~0 Gs in the exact middle of the gap (due to field cancellation).
* Figures show shear force of two same magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Protective zones (electronics) - warnings
MW 16x4 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	7.0 cm
Hearing aid	10 Gs (1.0 mT)	5.5 cm
Mechanical watch	20 Gs (2.0 mT)	4.5 cm
Mobile device	40 Gs (4.0 mT)	3.5 cm

Payment card	400 Gs (40.0 mT)	1.5 cm
HDD hard drive	600 Gs (60.0 mT)	1.0 cm

A strong magnetic field is a serious hazard to electronic devices as well as pacemakers. These neodymiums generate a field that disrupts operation of sensitive medical devices. Remember: the unseen radiation acts through matter and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - collision effects
MW 16x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	27.98 km/h (7.77 m/s)	0.18 J
30 mm	47.35 km/h (13.15 m/s)	0.52 J
50 mm	61.12 km/h (16.98 m/s)	0.87 J
100 mm	86.44 km/h (24.01 m/s)	1.74 J

Magnetic elements are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or injury to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the magnet. Wear safety glasses when handling with powerful specimens.

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. 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 retains merely a fraction of its max power.

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Heat tolerance

*For N38 grade, 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) = 0.35

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 cylinder magnet, manufactured from durable NdFeB material, which, at dimensions of Ø16x4 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 4.43 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 43.46 N with a weight of only 6.03 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 16.1 mm) using epoxy glues. To ensure stability 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 a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø16x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø16x4 mm, which, at a weight of 6.03 g, makes it an element with high magnetic energy density. The value of 43.46 N means that the magnet is capable of holding a weight many times exceeding its own mass of 6.03 g. 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 4 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Pros as well as cons of rare earth magnets.

Pros

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They do not lose power, even during approximately ten years – the decrease in lifting capacity is only ~1% (theoretically),
Neodymium magnets are characterized by exceptionally resistant to loss of magnetic properties caused by external magnetic fields,
By using a lustrous coating of gold, the element has an proper look,
Magnetic induction on the top side of the magnet turns out to be very high,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Considering the option of free molding and adaptation to unique requirements, neodymium magnets can be created in a variety of shapes and sizes, which expands the range of possible applications,
Wide application in innovative solutions – they serve a role in computer drives, electric drive systems, diagnostic systems, as well as complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems

Weaknesses

Disadvantages of neodymium magnets:

At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
We suggest cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
Health risk to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Additionally, small elements of these devices are able to disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?

Magnet power was defined for the most favorable conditions, including:

on a base made of structural steel, perfectly concentrating the magnetic field
with a cross-section minimum 10 mm
with an polished touching surface
without the slightest air gap between the magnet and steel
during detachment in a direction vertical to the mounting surface
at temperature room level

Key elements affecting lifting force

In real-world applications, the actual holding force is determined by many variables, presented from most significant:

Gap (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, rust or debris).
Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
Plate texture – ground elements guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
Thermal factor – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Safety rules for work with NdFeB magnets

Swallowing risk

These products are not suitable for play. Swallowing multiple magnets can lead to them pinching intestinal walls, which poses a direct threat to life and requires urgent medical intervention.

Conscious usage

Be careful. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can move away.

Keep away from computers

Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.

Heat sensitivity

Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. This process is irreversible.

Protective goggles

Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.

Nickel allergy

Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands and choose coated magnets.

Serious injuries

Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Threat to navigation

An intense magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.

Machining danger

Fire warning: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.

Life threat

Individuals with a ICD should maintain an safe separation from magnets. The magnetism can interfere with the operation of the life-saving device.

Caution! More info about hazards in the article: Safety of working with magnets.
