Pulling power drops significantly with every mm of distance. Note that even a microscopic distance (e.g., dirt, varnish, dust) significantly diminishes the holding power. Neodymiums work strongest during direct contact; air break weakens the power. Analyze how flashily the pull force drop, when the magnet does not touch flatly to the metal substrate. When calculating the assembly, avoid unnecessary gaps.

The table below defines the theoretical holding capacity necessary to initiate the shifting of the magnet downwards on a vertical steel wall (considering standard friction). This value depends on the gap size between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 7x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.21 kg / 0.46 pounds 207.0 g / 2.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.14 kg / 0.30 pounds 138.0 g / 1.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.15 pounds 69.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.35 kg / 0.76 pounds 345.0 g / 3.4 N

When mounting a element on a upright wall (e.g., a fridge), it you can count on only approx. 20%-30% of its nominal power. Gravity and a weak degree of grip mean that holders move down easier than they detach. Designing a wall mount? Remember that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the magnet will give way down under a significantly smaller weight. Using a rubber layer can drastically raise the stability.

12 mm	100%	0.69 kg / 1.52 pounds 690.0 g / 6.8 N

A too thin steel is unable to conduct the entire magnetic field, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the field will penetrate right through and the pull force will drop sharply. To achieve the maximum of this magnet's power, you require a sufficiently solid backing of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the magnet shows lower pull force. We advise picking the steel dimension according to the table below.

Classic neodymiums change their properties strength above the temperature limit. Watch out for overheating – heat can irreversibly destroy this product. With increasing heat, the neodymium's power briefly lowers. Refrain from using this product in hot environments higher than its working range. Ignoring the limit will cause irreversible degradation of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently sooner than long magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two magnets interact from a wider radius than a magnet and steel combination. Such a system of two magnets creates a more powerful interaction and a larger range of performance. Want to build a strong closure? Apply two magnets instead of one magnet and a steel. Exercise caution that when bringing together two magnets, the collision energy is massive. The levitation is a bit weaker than the attraction, but still significant.
*Field value between like poles is approximately ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Attention: Calculations show shear force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Hazards (electronics) - warnings
MW 7x1.5 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	3.0 cm

Extremely neodym field poses a real danger to electronic devices as well as pacemakers. These NdFeB products produce a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field acts through matter and glass. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Table 8: Dynamics (kinetic energy) - warning
MW 7x1.5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	40.43 km/h (11.23 m/s)	0.03 J

50 mm	90.34 km/h (25.09 m/s)	0.14 J
100 mm	127.75 km/h (35.49 m/s)	0.27 J

NdFeB products are prone to chipping – a violent impact against metal risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Kinetic force can cause material chips or injury to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the magnet. Use safety goggles when handling with powerful specimens.

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

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Warning: On a vertical surface, the magnet retains only a fraction of its perpendicular strength.

2. Plate thickness effect

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

3. Temperature resistance

*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) = 0.31

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, at dimensions of Ø7x1.5 mm, guarantees the highest energy density. This specific item features an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 0.69 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 6.75 N with a weight of only 0.43 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade 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 the strongest magnets in the same volume (Ø7x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø7x1.5 mm, which, at a weight of 0.43 g, makes it an element with high magnetic energy density. The value of 6.75 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.43 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 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.

Strengths as well as weaknesses of rare earth magnets.

Strengths

Apart from their consistent power, neodymium magnets have these key benefits:

They retain attractive force for nearly ten years – the drop is just ~1% (in theory),
They possess excellent resistance to magnetic field loss due to external magnetic sources,
A magnet with a smooth gold surface has better aesthetics,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Considering the potential of flexible molding and customization to individualized projects, NdFeB magnets can be manufactured in a variety of forms and dimensions, which expands the range of possible applications,
Universal use in modern technologies – they are utilized in HDD drives, electric motors, medical equipment, also industrial machines.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 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.
Limited ability of creating threads in the magnet and complex shapes - preferred is a housing - mounting mechanism.
Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small components of these magnets are able to be problematic in diagnostics 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

Maximum lifting capacity of the magnet – what it depends on?

The declared magnet strength represents the peak performance, recorded under optimal environment, meaning:

on a plate made of structural steel, optimally conducting the magnetic flux
whose thickness reaches at least 10 mm
with a plane perfectly flat
without the slightest insulating layer between the magnet and steel
during pulling in a direction perpendicular to the mounting surface
at standard ambient temperature

Practical lifting capacity: influencing factors

During everyday use, the real power depends on many variables, presented from crucial:

Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.

Safety rules for work with NdFeB magnets

Data carriers

Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.

Operating temperature

Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Nickel allergy

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop handling magnets and wear gloves.

Shattering risk

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

Life threat

For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.

Immense force

Use magnets consciously. Their huge power can surprise even experienced users. Plan your moves and respect their force.

Fire warning

Dust generated during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Finger safety

Large magnets can break fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.

Choking Hazard

Always store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are very dangerous.

Impact on smartphones

A strong magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.
