Magnetic force drops drastically with every mm of gap. Remember that every additional insulation layer (e.g., contamination, varnish, veneer) noticeably reduces the pull force. Magnetic products operate strongest during direct contact; distance kills the force. Observe how quickly the load capacity drop, when the product does not touch tightly to the steel surface. When planning the assembly, avoid additional spacers.

The following data presents the theoretical holding capacity needed to initiate the downward movement of the magnet downwards along a vertical steel plate (considering standard friction coefficient). This value is relative to the gap size between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 20x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.29 kg / 0.64 lbs 291.0 g / 2.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.19 kg / 0.43 lbs 194.0 g / 1.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.10 kg / 0.21 lbs 97.0 g / 1.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.49 kg / 1.07 lbs 485.0 g / 4.8 N

When mounting a element on a upright plane (e.g., a car body), it will only hold just about 1/5 of its maximum pull force. Gravity and a weak degree of grip cause that magnets move down faster than they pull off. Designing a vertical fastening? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the element will give way down under a significantly smaller cargo. Using a rubber coating can effectively improve the result.

A too thin steel is incapable of absorb the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a thin surface, the field will pass right through and the pull force will drop sharply. To squeeze full efficiency of this magnet's potential, you require a sufficiently solid element of metal. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the holder holds weaker. We recommend selecting the steel dimension according to the table below.

Standard neodymium magnets change their properties strength after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly demagnetize this magnet. With increasing heat, the magnet's force briefly lowers. Refrain from using this magnet close to ovens higher than its operating temperature limit. Ignoring the limit will lead to destruction of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) may lose charge permanently at lower temperatures than taller cylinders. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a neodymium and metal combination. The connection of two magnets creates a more powerful interaction and a larger range of performance. Designing a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Remember that when bringing together two magnets, the collision energy is massive. The repulsion force is marginally weaker than the attraction, but still impressive.
*Flux density between like poles drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Important: Calculations demonstrate shear force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to electronic devices and medical implants. These neodymiums generate a flux that destroys function of digital equipment. Notice: the invisible magnetic field acts through matter and glass. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are very brittle – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or injury to skin. Be sure to control the product during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when handling with powerful specimens.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Shear force

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

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) severely limits the holding force.

3. Heat tolerance

*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) = 0.12

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.

The offered product is an incredibly powerful rod magnet, made from durable NdFeB material, which, at dimensions of Ø20x1.5 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 0.97 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 9.50 N with a weight of only 3.53 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are strong enough for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø20x1.5), 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 Ø20x1.5 mm, which, at a weight of 3.53 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 0.97 kg (force ~9.50 N), which, with such defined dimensions, proves the high power of the NdFeB material. 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 1.5 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 diametrically if your project requires it.

Advantages as well as disadvantages of rare earth magnets.

Advantages

In addition to their pulling strength, neodymium magnets provide the following advantages:

Their magnetic field is durable, and after approximately 10 years it drops only by ~1% (theoretically),
Neodymium magnets are characterized by highly resistant to magnetic field loss caused by magnetic disturbances,
Thanks to the smooth finish, the layer of nickel, gold, or silver-plated gives an modern appearance,
Neodymium magnets create maximum magnetic induction on a small surface, which increases force concentration,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to freedom in forming and the capacity to modify to client solutions,
Huge importance in advanced technology sectors – they find application in computer drives, electric drive systems, diagnostic systems, and industrial machines.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also increases 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
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum magnetic pulling force – what affects it?

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

using a sheet made of mild steel, acting as a circuit closing element
with a cross-section minimum 10 mm
with an ideally smooth contact surface
under conditions of no distance (metal-to-metal)
during detachment in a direction vertical to the plane
at standard ambient temperature

Practical aspects of lifting capacity – factors

Effective lifting capacity impacted by specific conditions, such as (from most important):

Space 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.
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets

Combustion hazard

Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Keep away from electronics

Navigation devices and mobile phones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Respect the power

Handle magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their power.

ICD Warning

For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.

Product not for children

Only for adults. Tiny parts can be swallowed, causing severe trauma. Store out of reach of children and animals.

Thermal limits

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.

Finger safety

Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!

Protective goggles

Neodymium magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them breaking into shards.

Protect data

Data protection: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, timepieces).

Avoid contact if allergic

Studies show that nickel (standard magnet coating) is a strong allergen. If you have an allergy, avoid direct skin contact or select encased magnets.
