Pulling power drops sharply with every subsequent millimeter of distance. Keep in mind that even a very thin break (e.g., contamination, varnish, rust) significantly diminishes the holding power. Neodymiums work strongest during direct contact; air break kills the force. See how rapidly the load capacity plummet, when the magnet does not adhere directly to the metal substrate. When calculating the mounting, discard additional spacers.

The table below shows the theoretical shear load needed to initiate the slippage of the magnet downwards along a vertical steel wall (considering typical friction coefficient). This parameter is relative to the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 7x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.30 kg / 0.65 lbs 297.0 g / 2.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.20 kg / 0.44 lbs 198.0 g / 1.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.10 kg / 0.22 lbs 99.0 g / 1.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.50 kg / 1.09 lbs 495.0 g / 4.9 N

When placing a magnet on a upright wall (e.g., a fridge), it will only hold only about 1/5 of its maximum pull force. Gravity and a weak degree of grip influence the fact that holders slide down easier than they pop off the substrate. Want to create a hanger? Note that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the holder will give way down under a much lighter cargo. Using a rubber layer can effectively raise the stability.

A thin metal plate is incapable of take in the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a thin surface, the field will pass right through and the pull force will drop sharply. To utilize the maximum of this magnet's potential, you require a sufficiently solid backing of metal. The saturation effect causes that on thin elements (e.g., car bodies), the product shows lower pull force. We recommend selecting the steel cross-section according to the table below.

Standard neodymium magnets lose parameters above the temperature limit. Protect against heat – excessive heat can permanently demagnetize this product. As the temperature rises, the magnet's capacity temporarily decreases. Avoid using this product near heat sources exceeding its working range. Exceeding the critical threshold will cause destruction of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) may lose charge permanently at lower temperatures than taller cylinders. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a magnet and sheet setup. The connection of two magnets creates a more powerful interaction and a further horizon of performance. Want to build a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is massive. The levitation is slightly lower than the attraction, but still significant.
*Field value between like poles is approximately ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Attention: Figures show sliding force of dual same neodymium magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to electronic devices as well as medical implants. These neodymiums generate a flux that destroys function of digital equipment. Be aware: the unseen radiation penetrates the body and glass. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

NdFeB products are very brittle – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Impact energy can trigger coating fragments or painful pinches to skin. Hold the magnet firmly during installation so it doesn't hit violently against the steel surface. A collision at high speed means shattering 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. Sliding resistance

*Warning: On a vertical wall, the magnet retains only ~20% of its perpendicular strength.

2. Steel saturation

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

3. Power loss vs temp

*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) = 0.39

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 cylinder magnet, composed of advanced NdFeB material, which, with dimensions of Ø7x2 mm, guarantees optimal power. The MW 7x2 / N38 component is characterized by a tolerance of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 0.99 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 9.76 N with a weight of only 0.58 g, this rod is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 7.1 mm) using epoxy glues. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø7x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 7 mm and height 2 mm. The value of 9.76 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.58 g. 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 2 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.

Advantages and disadvantages of rare earth magnets.

Strengths

Apart from their notable magnetism, neodymium magnets have these key benefits:

They retain full power for nearly ten years – the loss is just ~1% (in theory),
They do not lose their magnetic properties even under external field action,
In other words, due to the metallic finish of silver, the element looks attractive,
The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
Thanks to freedom in constructing and the capacity to customize to individual projects,
Key role in modern industrial fields – they are utilized in HDD drives, drive modules, medical devices, as well as technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in miniature devices

Limitations

Disadvantages of NdFeB magnets:

At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets decrease their power 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 stability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic holder, due to difficulties in creating threads inside the magnet and complicated shapes.
Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small components of these magnets can be problematic in diagnostics medical when they are in the body.
With mass production the cost of neodymium magnets is a challenge,

Pull force analysis

Magnetic strength at its maximum – what it depends on?

Information about lifting capacity is the result of a measurement for optimal configuration, including:

on a block made of structural steel, perfectly concentrating the magnetic field
with a thickness minimum 10 mm
with an polished touching surface
with direct contact (no paint)
during detachment in a direction vertical to the plane
at standard ambient temperature

Magnet lifting force in use – key factors

In practice, the actual lifting capacity depends on several key aspects, presented from crucial:

Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Angle of force application – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material composition – not every steel reacts the same. Alloy additives weaken the attraction effect.
Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Safety rules for work with NdFeB magnets

GPS Danger

GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.

Powerful field

Handle with care. Neodymium magnets act from a distance and connect with huge force, often faster than you can move away.

Implant safety

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Choking Hazard

Always store magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are tragic.

Electronic hazard

Do not bring magnets close to a purse, computer, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Hand protection

Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!

Shattering risk

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

Maximum temperature

Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. This process is irreversible.

Warning for allergy sufferers

It is widely known that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands and opt for coated magnets.

Mechanical processing

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