Magnetic force drops significantly with every subsequent millimeter of distance. Keep in mind that even a microscopic distance (e.g., contamination, paint, rust) strongly weakens the grip. Magnets work most effectively at the point of direct contact; air break drastically cuts the power. See how rapidly the parameters fall, when the product does not touch flatly to the metal substrate. When designing the arrangement, avoid redundant distances.

The following data calculates the estimated weight limit needed to start the sliding of the magnet downwards along a upright steel wall (assuming standard friction coefficient). The holding force is a function of the gap size between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 45x35 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	20.69 kg / 45.62 lbs 20694.0 g / 203.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	13.80 kg / 30.41 lbs 13796.0 g / 135.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	6.90 kg / 15.21 lbs 6898.0 g / 67.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	34.49 kg / 76.04 lbs 34490.0 g / 338.3 N

When mounting a magnet on a vertical surface (e.g., a fridge), it will only hold only approx. 1/5 of nominal attraction strength. Gravitational force as well as a low friction coefficient mean that products slide down faster than they pop off the substrate. Planning a hanger? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the magnet will slip down under a significantly smaller load. Application of an anti-slip layer can significantly improve the result.

Table 4: Steel thickness (saturation) - power losses
MW 45x35 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	3%	2.30 kg / 5.07 lbs 2299.3 g / 22.6 N
1 mm	8%	5.75 kg / 12.67 lbs 5748.3 g / 56.4 N
2 mm	17%	11.50 kg / 25.35 lbs 11496.7 g / 112.8 N
3 mm	25%	17.25 kg / 38.02 lbs 17245.0 g / 169.2 N
5 mm	42%	28.74 kg / 63.36 lbs 28741.7 g / 282.0 N
10 mm	83%	57.48 kg / 126.73 lbs 57483.3 g / 563.9 N
11 mm	92%	63.23 kg / 139.40 lbs 63231.7 g / 620.3 N
12 mm	100%	68.98 kg / 152.07 lbs 68980.0 g / 676.7 N

A thin metal plate is incapable of conduct the full magnetic flux, which weakens actual performance of the magnet. Should you install a neodymium to a too thin substrate, the field will pass right through and the holding will be smaller. To utilize the maximum of this neodymium's potential, you need a suitably thick piece of steel. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the holder shows lower pull force. We recommend selecting the steel dimension based on the following data.

Table 5: Thermal resistance (stability) - power drop

100 °C	-28.8%	49.11 kg / 108.28 lbs 49113.8 g / 481.8 N

Standard neodymium magnets change their properties power after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently demagnetize this product. With every degree above norm, the neodymium's power temporarily lowers. Avoid using this product close to ovens higher than its operating temperature limit. Too high temperature will cause destruction of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a wider radius than a neodymium and metal setup. The connection of two magnets creates a more powerful interaction and a further horizon of performance. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is massive. The levitation is a bit weaker than the attraction, but still large.
*Flux density for N-N configuration reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
* Results refer to friction force of a pair of same magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Hazards (implants) - precautionary measures
MW 45x35 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	26.5 cm
Hearing aid	10 Gs (1.0 mT)	20.5 cm
Mechanical watch	20 Gs (2.0 mT)	16.0 cm
Phone / Smartphone	40 Gs (4.0 mT)	12.5 cm
Remote	50 Gs (5.0 mT)	11.5 cm
Payment card	400 Gs (40.0 mT)	5.0 cm
HDD hard drive	600 Gs (60.0 mT)	4.0 cm

A strong magnetic field is a large risk to IT equipment and pacemakers. These NdFeB products produce a flux that destroys function of digital equipment. Notice: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - collision effects
MW 45x35 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	15.46 km/h (4.29 m/s)	3.85 J
30 mm	22.87 km/h (6.35 m/s)	8.42 J
50 mm	29.06 km/h (8.07 m/s)	13.61 J
100 mm	41.00 km/h (11.39 m/s)	27.07 J

Magnetic elements are prone to chipping – a collision with steel causes immediate chipping. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when playing with powerful specimens.

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

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Note: On a vertical surface, the magnet holds merely a fraction of its perpendicular strength.

2. Efficiency vs thickness

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

3. Thermal stability

*For N38 material, 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) = 0.78

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 a very strong cylindrical magnet, produced from advanced NdFeB material, which, with dimensions of Ø45x35 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 68.98 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 676.73 N with a weight of only 417.49 g, this cylindrical magnet is indispensable in miniature devices 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., 45.1 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 durability of the connection.

Magnets N38 are strong enough for the majority of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø45x35), 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 Ø45x35 mm, which, at a weight of 417.49 g, makes it an element with impressive magnetic energy density. The value of 676.73 N means that the magnet is capable of holding a weight many times exceeding its own mass of 417.49 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 35 mm), which means that the N and S poles are located on the flat, circular surfaces. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. 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.

Strengths

Besides their exceptional field intensity, neodymium magnets offer the following advantages:

They have constant strength, and over around ten years their performance decreases symbolically – ~1% (in testing),
Magnets effectively defend themselves against loss of magnetization caused by external fields,
In other words, due to the reflective finish of gold, the element becomes visually attractive,
Magnets are distinguished by impressive magnetic induction on the outer side,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
In view of the ability of accurate forming and customization to unique projects, NdFeB magnets can be modeled in a broad palette of forms and dimensions, which increases their versatility,
Huge importance in advanced technology sectors – they find application in data components, electric drive systems, advanced medical instruments, as well as multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in small systems

Disadvantages

Cons of neodymium magnets and ways of using them

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 extremely resistant to heat
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We recommend casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex forms.
Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

Breakaway force was defined for ideal contact conditions, including:

using a sheet made of mild steel, acting as a magnetic yoke
with a cross-section no less than 10 mm
with an ground contact surface
under conditions of gap-free contact (surface-to-surface)
for force applied at a right angle (in the magnet axis)
at ambient temperature room level

What influences lifting capacity in practice

Bear in mind that the magnet holding may be lower depending on the following factors, in order of importance:

Distance – the presence of foreign body (paint, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Plate material – low-carbon steel attracts best. Alloy admixtures lower magnetic permeability and lifting capacity.
Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Warnings

Medical interference

Patients with a heart stimulator should maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the implant.

Safe distance

Avoid bringing magnets near a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.

Allergy Warning

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness appears, cease working with magnets and wear gloves.

Risk of cracking

Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.

Thermal limits

Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Combustion hazard

Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.

Threat to navigation

Remember: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.

This is not a toy

These products are not toys. Swallowing several magnets can lead to them attracting across intestines, which poses a direct threat to life and requires immediate surgery.

Crushing risk

Big blocks can smash fingers instantly. Never place your hand between two attracting surfaces.

Handling rules

Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Danger! More info about hazards in the article: Magnet Safety Guide.
