Pulling power decreases sharply with every mm of gap. Remember that even a very thin break (e.g., contamination, varnish, dust) noticeably weakens the grip. Magnets work optimally in perfect adhesion; gap drastically cuts the power. Analyze how quickly the load capacity drop, when the magnet does not touch tightly to the metal substrate. When calculating the arrangement, avoid redundant distances.

The following data presents the theoretical holding capacity sufficient to cause the slippage of the magnet down on a upright steel plate (assuming typical friction). This parameter depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MW 55x25 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	27.68 kg / 61.01 pounds 27675.0 g / 271.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	18.45 kg / 40.68 pounds 18450.0 g / 181.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	9.23 kg / 20.34 pounds 9225.0 g / 90.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	46.13 kg / 101.69 pounds 46125.0 g / 452.5 N

When hanging a element on a upright plane (e.g., a fridge), it will only hold only about 20%-30% of its nominal power. Gravitational force and a low friction coefficient cause that products slip faster than they pull off. Planning a hanger? Note that the shear force is much weaker than the maximum static pull force. On a slippery surface, the holder will slip down under a noticeably lighter weight. Application of an anti-slip layer can significantly raise the stability.

3 mm	25%	23.06 kg / 50.84 pounds 23062.5 g / 226.2 N
5 mm	42%	38.44 kg / 84.74 pounds 38437.5 g / 377.1 N
10 mm	83%	76.88 kg / 169.48 pounds 76875.0 g / 754.1 N
11 mm	92%	84.56 kg / 186.43 pounds 84562.5 g / 829.6 N
12 mm	100%	92.25 kg / 203.38 pounds 92250.0 g / 905.0 N

A too thin steel is incapable of take in the full magnetic flux, which squanders power of the magnet. Should you attach a powerful product to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To achieve 100% of this magnet's potential, you require a sufficiently solid backing of metal. The saturation effect means that on delicate walls (e.g., appliance housings), the product works worse. We advise picking the steel dimension from these parameters.

Standard neodymium magnets change their properties power after exceeding the maximum temperature. Avoid high temperatures – heat can permanently damage this product. As the temperature rises, the magnet's power briefly decreases. Do not use this product in hot environments higher than its operating temperature limit. Ignoring the limit will cause permanent loss of magnetism.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low Pc) risk losing magnetic properties sooner than long magnets. Red status in the table points to permanent field degradation for this particular item.

Two magnets attract each other from a wider radius than a neodymium and metal setup. The setup of two magnets generates a stronger field and a wider radius of performance. Planning to create a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the collision energy is massive. The repulsion force is a bit weaker than the connection force, but still significant.
*Field value in repulsion mode drops to ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
* Calculations show shear force of two same neodymium magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a large risk to IT equipment and pacemakers. These magnets generate a field that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and housings. Special caution must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - warning
MW 55x25 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	18.05 km/h (5.01 m/s)	5.60 J
30 mm	25.98 km/h (7.22 m/s)	11.60 J
50 mm	32.63 km/h (9.06 m/s)	18.30 J
100 mm	45.90 km/h (12.75 m/s)	36.21 J

Magnetic elements are delicate – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or injury to skin. Always hold the magnet during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when playing with large magnets.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Warning: On a vertical wall, the magnet holds only approx. 20-30% of its nominal pull.

2. Steel saturation

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

3. Thermal stability

*For standard magnets, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.55

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 a very strong rod magnet, produced from durable NdFeB material, which, with dimensions of Ø55x25 mm, guarantees optimal power. This specific item features high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 92.25 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 904.94 N with a weight of only 445.47 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 55.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø55x25), 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 55 mm and height 25 mm. The value of 904.94 N means that the magnet is capable of holding a weight many times exceeding its own mass of 445.47 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 25 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 diametrically if your project requires it.

Pros and cons of rare earth magnets.

Advantages

Apart from their notable magnetic energy, neodymium magnets have these key benefits:

They do not lose magnetism, even during around 10 years – the drop in power is only ~1% (according to tests),
They show high resistance to demagnetization induced by external magnetic fields,
The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
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...
Thanks to flexibility in designing and the ability to modify to client solutions,
Significant place in high-tech industry – they are used in hard drives, motor assemblies, precision medical tools, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in miniature devices

Weaknesses

Problematic aspects of neodymium magnets and ways of using them

To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited possibility of making threads in the magnet and complicated forms - recommended is a housing - magnet mounting.
Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these products can be problematic in diagnostics medical after entering the body.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

Magnetic strength at its maximum – what affects it?

The specified lifting capacity represents the limit force, recorded under ideal test conditions, meaning:

on a plate made of structural steel, effectively closing the magnetic field
with a cross-section minimum 10 mm
characterized by even structure
with direct contact (no paint)
for force applied at a right angle (in the magnet axis)
in stable room temperature

Determinants of lifting force in real conditions

Effective lifting capacity is influenced by working environment parameters, including (from priority):

Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the holding force.

Safety rules for work with NdFeB magnets

Conscious usage

Exercise caution. Rare earth magnets attract from a long distance and connect with huge force, often quicker than you can move away.

GPS Danger

An intense magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to avoid breaking the sensors.

Data carriers

Do not bring magnets close to a wallet, laptop, or TV. The magnetism can destroy these devices and erase data from cards.

Keep away from children

Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from children and animals.

Risk of cracking

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them breaking into shards.

Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Life threat

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

Dust explosion hazard

Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.

Skin irritation risks

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop handling magnets and wear gloves.

Hand protection

Big blocks can break fingers instantly. Never put your hand between two attracting surfaces.
