Magnetic force decreases sharply with every mm of distance. Keep in mind that even a microscopic distance (e.g., dirt, paint, veneer) strongly weakens the grip. Magnets work most effectively at the point of direct contact; gap kills the force. Observe how flashily the load capacity fall, when the magnet does not adhere flatly to the metal substrate. When planning the assembly, avoid redundant distances.

This section shows the approximate shear load sufficient to start the downward movement of the magnet vertically along a vertical metal surface (considering standard friction coefficient). This value depends on the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MW 5x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.24 kg / 0.52 pounds 237.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.16 kg / 0.35 pounds 158.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 pounds 79.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.40 kg / 0.87 pounds 395.0 g / 3.9 N

When hanging a element on a upright wall (e.g., a board), it you can count on only about 1/5 of its nominal power. Gravity and a low friction coefficient mean that magnets slip easier than they pop off the substrate. Designing a vertical fastening? Consider that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the element will slide down under a noticeably lighter load. Utilizing a rubberized layer can effectively raise the stability.

12 mm	100%	0.79 kg / 1.74 pounds 790.0 g / 7.7 N

A thin sheet cannot focus the entire magnetic field, which squanders power of the magnet. If you mount a strong magnet to a thin surface, the flux will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this magnet's potential, you require a sufficiently solid backing of metal. The material oversaturation causes that on sheet metal structures (e.g., thin profiles), the holder shows lower pull force. We advise picking the steel dimension according to the table below.

Standard neodymium magnets irreversibly lose parameters past the thermal threshold. Protect against heat – excessive heat can irreversibly damage this magnet. As the temperature rises, the neodymium's capacity momentarily lowers. Do not use this product in hot environments higher than its operating temperature limit. Ignoring the limit will lead to permanent loss of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, but also on the magnet's shape. Flat magnets (pancake types) may lose charge permanently sooner compared to rod magnets. Red status in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal combination. Such a system of two magnets generates a stronger field and a further horizon of action. Designing a strong closure? Use a pair of magnets instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the collision energy is massive. The levitation is marginally weaker than the attraction, but still significant.
*Flux density between like poles reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Note: Results show sliding force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to IT equipment as well as medical implants. These neodymiums produce a flux that destroys function of digital equipment. Remember: the unseen radiation acts through matter and plastic. Special caution must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Impact energy can cause material chips or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the magnet. Use safety goggles when handling with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet retains merely ~20% of its max power.

2. Plate thickness effect

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

3. Temperature resistance

*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) = 0.89

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.

This product is an exceptionally strong cylinder magnet, produced from durable NdFeB material, which, at dimensions of Ø5x5 mm, guarantees optimal power. This specific item boasts an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.79 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 7.76 N with a weight of only 0.74 g, this cylindrical magnet is indispensable in electronics 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., 5.1 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 high repeatability of the connection.

Magnets N38 are strong enough for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø5x5), 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 5 mm and height 5 mm. The key parameter here is the holding force amounting to approximately 0.79 kg (force ~7.76 N), which, with such compact 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 5 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.

Advantages and disadvantages of neodymium magnets.

Pros

Besides their immense magnetic power, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
They do not lose their magnetic properties even under close interference source,
In other words, due to the aesthetic layer of silver, the element gains visual value,
Magnetic induction on the working layer of the magnet remains very high,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Possibility of custom modeling as well as adapting to specific needs,
Wide application in advanced technology sectors – they are utilized in mass storage devices, electric motors, medical devices, also other advanced devices.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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 stable to moisture, in case of application outdoors
Due to limitations in creating threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these devices are able to be problematic in diagnostics medical after entering the body.
Due to expensive raw materials, their price is higher than average,

Lifting parameters

Detachment force of the magnet in optimal conditions – what it depends on?

The load parameter shown represents the peak performance, measured under laboratory conditions, namely:

using a sheet made of mild steel, acting as a magnetic yoke
whose thickness equals approx. 10 mm
characterized by even structure
with total lack of distance (without impurities)
for force acting at a right angle (in the magnet axis)
at temperature room level

What influences lifting capacity in practice

Holding efficiency is affected by specific conditions, such as (from priority):

Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Load vector – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Stainless steels may attract less.
Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
Thermal environment – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Safe handling of neodymium magnets

Nickel coating and allergies

Medical facts indicate that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact or select coated magnets.

ICD Warning

Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Keep away from computers

Avoid bringing magnets near a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.

Phone sensors

Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Risk of cracking

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them shattering into shards.

Bone fractures

Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Thermal limits

Do not overheat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Do not underestimate power

Handle magnets with awareness. Their immense force can surprise even experienced users. Stay alert and do not underestimate their power.

Mechanical processing

Dust created during machining of magnets is flammable. Do not drill into magnets unless you are an expert.

Choking Hazard

Adult use only. Small elements can be swallowed, causing severe trauma. Keep out of reach of kids and pets.

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