Pulling power weakens significantly per each millimeter of gap. Remember that even the smallest gap (e.g., dirt, varnish, veneer) noticeably weakens the grip. Magnetic products operate optimally at the point of direct contact; distance kills the power. See how flashily the parameters plummet, when the product does not adhere directly to the steel surface. When planning the arrangement, discard additional spacers.

The table below presents the theoretical weight limit needed to start the downward movement of the magnet downwards against a upright steel wall (assuming standard friction). This parameter is a function of the separation distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
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 placing a magnet on a vertical surface (e.g., a car body), it will only hold just about 20%-30% of nominal attraction strength. Gravity as well as a low friction coefficient influence the fact that magnets slide down faster than they pull off. Planning a hanger? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a significantly smaller cargo. Application of an anti-slip coating can significantly raise the stability.

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

A thin sheet is not enough to absorb the full magnetic flux, which weakens actual performance of the holder. Should you mount a strong magnet to a too thin substrate, the field will pass right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's power, you require a sufficiently solid element of metal. The saturation effect means that on sheet metal structures (e.g., car bodies), the product works worse. We suggest choosing the steel dimension from these parameters.

Ordinary NdFeB products irreversibly lose strength after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently damage this product. As the temperature rises, the neodymium's power momentarily lowers. Refrain from using this product in hot environments exceeding its safe range. Too high temperature will result in destruction of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) are more susceptible to demagnetization sooner than long magnets. Red status in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel combination. Such a system of magnet-to-magnet generates a stronger field and a wider radius of action. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the pinch force is massive. The repulsion force is marginally weaker than the attraction, but still impressive.
*Field value in repulsion mode drops to ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Figures apply to shear force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Safety (HSE) (implants) - warnings

Extremely neodym field is a real danger to electronics as well as pacemakers. These NdFeB products generate a field that destroys function of sensitive medical devices. Remember: the invisible magnetic field acts through matter and glass. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (cracking risk) - collision effects
MW 5x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	32.96 km/h (9.16 m/s)	0.03 J

100 mm	104.20 km/h (28.95 m/s)	0.31 J

Magnetic elements are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can destroy the magnet or painful pinches to skin. Always hold the magnet during installation so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when playing with powerful specimens.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Shear force

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

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) drastically weakens 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) = 0.89

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 exceptionally strong cylindrical magnet, composed of modern NdFeB material, which, at dimensions of Ø5x5 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and professional build quality, making it an ideal solution for the most demanding 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 quick order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects 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 rod is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 5.1 mm) using 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 the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø5x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø5x5 mm, which, at a weight of 0.74 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 0.79 kg (force ~7.76 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it 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.

Strengths and weaknesses of neodymium magnets.

Strengths

Besides their remarkable strength, neodymium magnets offer the following advantages:

They retain magnetic properties for around ten years – the drop is just ~1% (in theory),
They do not lose their magnetic properties even under close interference source,
The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnets are characterized by impressive magnetic induction on the active area,
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...
In view of the potential of flexible forming and customization to custom needs, NdFeB magnets can be created in a variety of forms and dimensions, which expands the range of possible applications,
Universal use in innovative solutions – they are used in mass storage devices, electric motors, medical devices, and multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in miniature devices

Weaknesses

Disadvantages of neodymium magnets:

To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
Neodymium magnets lose their force 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 durability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
Due to limitations in producing nuts and complicated shapes in magnets, we recommend using casing - magnetic holder.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
Due to neodymium price, their price exceeds standard values,

Lifting parameters

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

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

with the contact of a sheet made of low-carbon steel, guaranteeing maximum field concentration
possessing a massiveness of at least 10 mm to avoid saturation
with an ideally smooth contact surface
with direct contact (without coatings)
for force applied at a right angle (in the magnet axis)
at room temperature

Lifting capacity in real conditions – factors

Real force impacted by specific conditions, mainly (from most important):

Gap (between the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Material type – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets

Protective goggles

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Medical implants

Patients with a ICD have to maintain an large gap from magnets. The magnetic field can disrupt the operation of the implant.

Heat sensitivity

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

Dust is flammable

Machining of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Keep away from computers

Intense magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Impact on smartphones

A strong magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a smartphone to prevent damaging the sensors.

Metal Allergy

Certain individuals suffer from a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause an allergic reaction. We suggest use protective gloves.

Serious injuries

Big blocks can crush fingers instantly. Do not put your hand between two attracting surfaces.

Swallowing risk

Absolutely keep magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are fatal.

Caution required

Handle with care. Rare earth magnets act from a long distance and snap with huge force, often faster than you can react.

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