Pulling power decreases sharply with every mm of distance. Remember that even a very thin break (e.g., contamination, varnish, rust) strongly weakens the grip. Magnetic products operate optimally at the point of direct contact; air break nullifies the power. Observe how flashily the load capacity fall, when the magnet does not adhere flatly to the metal substrate. When designing the assembly, discard additional spacers.

The following data indicates the theoretical shear load required to initiate the shifting of the magnet vertically on a upright steel wall (considering typical friction coefficient). This value depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - 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 lbs 27675.0 g / 271.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	18.45 kg / 40.68 lbs 18450.0 g / 181.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	9.23 kg / 20.34 lbs 9225.0 g / 90.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	46.13 kg / 101.69 lbs 46125.0 g / 452.5 N

When hanging a holder on a vertical plane (e.g., a board), it will only hold barely about 20%-30% of its nominal power. Gravity and a low friction coefficient cause that magnets move down faster than they detach. Want to create a wall mount? Remember that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the element will slide down under a significantly smaller cargo. Using a rubber pad can drastically improve the result.

MW 55x25 / N38

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

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

A too thin steel is not enough to focus the entire magnetic field, which squanders power of the magnet. Should you mount a strong magnet to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this magnet's potential, you need a suitably thick element of steel. The material oversaturation causes that on thin elements (e.g., thin profiles), the product holds weaker. We advise picking the steel cross-section according to the table below.

100 °C	-28.8%	65.68 kg / 144.80 lbs 65682.0 g / 644.3 N

Ordinary NdFeB products irreversibly lose parameters past the thermal threshold. Avoid high temperatures – heat can irreversibly destroy this magnet. With every degree above norm, the neodymium's capacity briefly lowers. Refrain from using this product in hot environments higher than its operating temperature limit. Exceeding the critical threshold will cause destruction of magnetism.

*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) may lose charge permanently at lower temperatures than taller cylinders. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products interact from a wider radius than a magnet and sheet setup. The setup of two magnets produces a massive flux and a wider radius of operation. Want to build a solid fastener? Apply two magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the pinch force is huge. The levitation is slightly lower than the attraction, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Important: Figures refer to friction force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a serious hazard to IT equipment and medical implants. These NdFeB products produce a field that disrupts operation of digital equipment. Notice: the invisible magnetic field passes through tissues and housings. Special caution must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or dangerous crushing to skin. Be sure to control the product during bringing near metal so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when playing with powerful specimens.

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

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. Shear force

*Caution: On a vertical surface, the magnet retains merely approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Power loss vs temp

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

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

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

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 incredibly powerful cylindrical magnet, composed of durable NdFeB material, which, with dimensions of Ø55x25 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 92.25 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects 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 maximum induction on a small surface counts. Thanks to the pull force 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 tolerance of ±0.1mm, 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 automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø55x25), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø55x25 mm, which, at a weight of 445.47 g, makes it an element with high magnetic energy density. 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 protects the surface against external factors, giving it an aesthetic, silvery shine.

This rod magnet 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 through the diameter if your project requires it.

Pros as well as cons of rare earth magnets.

Benefits

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
They possess excellent resistance to weakening of magnetic properties as a result of external fields,
By using a lustrous coating of gold, the element has an nice look,
Magnetic induction on the working layer of the magnet turns out to be impressive,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
Thanks to modularity in forming and the ability to modify to unusual requirements,
Wide application in high-tech industry – they are commonly used in magnetic memories, drive modules, medical equipment, also technologically advanced constructions.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves 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, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing nuts and complex forms in magnets, we recommend using cover - magnetic mount.
Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these products can complicate diagnosis medical when they are in the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Best holding force of the magnet in ideal parameters – what affects it?

Breakaway force is the result of a measurement for optimal configuration, including:

using a base made of mild steel, functioning as a ideal flux conductor
whose transverse dimension is min. 10 mm
with an ideally smooth touching surface
with total lack of distance (no coatings)
under perpendicular force vector (90-degree angle)
at conditions approx. 20°C

What influences lifting capacity in practice

Effective lifting capacity is influenced by specific conditions, such as (from priority):

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
Base massiveness – insufficiently thick sheet does not close the flux, causing part of the flux to be lost into the air.
Chemical composition of the base – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

H&S for magnets

Fire risk

Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.

Nickel coating and allergies

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness happens, immediately stop working with magnets and use protective gear.

Choking Hazard

Adult use only. Tiny parts can be swallowed, leading to serious injuries. Store away from kids and pets.

Shattering risk

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.

Maximum temperature

Keep cool. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).

Implant safety

Warning for patients: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Magnetic interference

A strong magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Keep magnets near a device to prevent breaking the sensors.

Do not underestimate power

Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Think ahead.

Hand protection

Pinching hazard: The pulling power is so great that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.

Magnetic media

Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
