Pulling power drops significantly with every subsequent millimeter of distance. Remember that even a very thin break (e.g., contamination, varnish, veneer) noticeably diminishes the holding power. Magnetic products operate optimally at the point of direct contact; distance nullifies the power. Notice how rapidly the parameters plummet, when the magnet does not adhere directly to the steel surface. When designing the assembly, discard redundant distances.

The table below indicates the theoretical shear load needed to start the slippage of the magnet downwards against a upright steel plate (considering typical friction coefficient). The holding force varies with the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 5x7 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.20 kg / 0.44 LBS 201.0 g / 2.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.13 kg / 0.30 LBS 134.0 g / 1.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.15 LBS 67.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.34 kg / 0.74 LBS 335.0 g / 3.3 N

When placing a element on a upright plane (e.g., a fridge), it will only hold only approx. 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that products move down easier than they pull off. Planning a vertical fastening? Consider 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 raise the stability.

12 mm	100%	0.67 kg / 1.48 LBS 670.0 g / 6.6 N

A too thin steel is unable to take in the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To utilize 100% of this neodymium's power, you require a sufficiently solid piece of metal. The saturation effect causes that on delicate walls (e.g., car bodies), the magnet shows lower pull force. We recommend selecting the steel thickness from these parameters.

Standard neodymium magnets lose strength after exceeding the maximum temperature. Avoid high temperatures – heat can permanently demagnetize this magnet. With every degree above norm, the magnet's capacity briefly decreases. Avoid using this magnet close to ovens higher than its safe range. Exceeding the critical threshold will cause permanent loss of magnetism.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod magnets. Warning indicator in the table signals permanent field degradation for this particular item.

Two magnets interact from a much further distance than a neodymium and metal setup. The setup of magnet-to-magnet generates a stronger field and a larger range of operation. Planning to create a strong closure? Apply two magnets instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the pinch force is extreme. The levitation is slightly lower than the connection force, but still significant.
*The magnetic induction in repulsion mode drops to ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Attention: Figures apply to sliding force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a large risk to electronic devices and pacemakers. These NdFeB products generate a field that destroys function of digital equipment. Notice: the invisible magnetic field passes through tissues and housings. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - warning
MW 5x7 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	25.73 km/h (7.15 m/s)	0.03 J
30 mm	44.55 km/h (12.38 m/s)	0.08 J
50 mm	57.52 km/h (15.98 m/s)	0.13 J
100 mm	81.34 km/h (22.59 m/s)	0.26 J

Magnetic elements are prone to chipping – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Kinetic force can destroy the magnet or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when handling with powerful specimens.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

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

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) significantly weakens 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) = 1.05

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.

This product is a very strong cylindrical magnet, composed of modern NdFeB material, which, at dimensions of Ø5x7 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.67 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Additionally, 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 electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 6.60 N with a weight of only 1.03 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure long-term durability in industry, specialized industrial adhesives 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 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 (Ø5x7), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 5 mm and height 7 mm. The key parameter here is the lifting capacity amounting to approximately 0.67 kg (force ~6.60 N), which, with such defined dimensions, proves the high grade of the NdFeB material. 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 7 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.

Strengths and weaknesses of neodymium magnets.

Advantages

Besides their high retention, neodymium magnets are valued for these benefits:

They retain attractive force for nearly 10 years – the drop is just ~1% (in theory),
Magnets perfectly resist against demagnetization caused by foreign field sources,
Thanks to the metallic finish, the plating of nickel, gold, or silver gives an visually attractive appearance,
Magnets have excellent 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 possibility of free forming and customization to specialized requirements, NdFeB magnets can be produced in a variety of shapes and sizes, which increases their versatility,
Wide application in future technologies – they are commonly used in magnetic memories, brushless drives, precision medical tools, also complex engineering applications.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Problematic aspects of neodymium magnets: tips and applications.

Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in creating threads and complex forms in magnets, we propose using casing - magnetic mechanism.
Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical after entering the body.
Due to complex production process, their price exceeds standard values,

Holding force characteristics

Maximum magnetic pulling force – what affects it?

The specified lifting capacity refers to the peak performance, obtained under laboratory conditions, namely:

using a base made of mild steel, functioning as a ideal flux conductor
whose transverse dimension equals approx. 10 mm
with a plane free of scratches
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (in the magnet axis)
at conditions approx. 20°C

Impact of factors on magnetic holding capacity in practice

During everyday use, the real power depends on a number of factors, listed from the most important:

Distance (betwixt the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Chemical composition of the base – mild steel gives the best results. Alloy steels lower magnetic properties and holding force.
Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets

Pacemakers

Warning for patients: Powerful magnets affect electronics. Keep minimum 30 cm distance or request help to handle the magnets.

Skin irritation risks

It is widely known that nickel (the usual finish) is a strong allergen. If you have an allergy, prevent direct skin contact and select coated magnets.

Keep away from computers

Do not bring magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.

Mechanical processing

Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Fragile material

Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.

Threat to navigation

Be aware: neodymium magnets generate a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and GPS.

Permanent damage

Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.

Danger to the youngest

Absolutely store magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are life-threatening.

Serious injuries

Pinching hazard: The pulling power is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.

Safe operation

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
