Grip strength weakens sharply per each millimeter of spacing. Remember that every additional insulation layer (e.g., contamination, paint, dust) noticeably reduces the pull force. Magnetic products work most effectively during direct contact; distance drastically cuts the force. See how quickly the parameters drop, when the product does not adhere directly to the metal substrate. When calculating the assembly, eliminate redundant distances.

This section shows the approximate weight limit needed to start the shifting of the magnet vertically along a upright steel wall (considering standard friction). This value depends on the gap size between the magnet and the surface.

When hanging a element on a upright plane (e.g., a car body), it will only hold just about 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that holders slide down easier than they pull off. Planning a wall mount? Note that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the holder will give way down under a significantly smaller weight. Using a rubber coating can significantly raise the stability.

A thin sheet is unable to focus the full magnetic flux, which weakens actual performance of the holder. If you install a neodymium to a weak sheet, the field will pass right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's power, you need a suitably thick backing of steel. The saturation effect means that on delicate walls (e.g., appliance housings), the holder works worse. We advise picking the steel thickness according to the table below.

Ordinary NdFeB products change their properties strength above the temperature limit. Protect against heat – high temperature can irreversibly damage this product. As the temperature rises, the magnet's force briefly lowers. Avoid using this magnet in hot environments exceeding its safe range. Too high temperature will lead to permanent loss of magnetism.
*Technical advisory: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) are more susceptible to demagnetization sooner than long magnets. Red status in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. The connection of two magnets generates a stronger field and a larger range of performance. Designing a strong closure? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the impact force is massive. The repulsion force is slightly lower than the attraction, but still significant.
*Flux density between like poles is approximately ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Important: Figures apply to shear force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronic devices as well as medical implants. These neodymiums generate a field that destroys function of sensitive medical devices. Remember: the unseen radiation passes through tissues and glass. Exceptional care must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Magnetic elements are prone to chipping – a violent impact against 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 with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear safety glasses when working 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!
The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.
1. Sliding resistance

*Caution: On a vertical surface, the magnet holds just ~20% of its max power.

2. Efficiency vs thickness

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

3. Thermal stability

*For N38 material, the safety limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.21

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 Pc (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 Pc 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 extremely powerful cylinder magnet, produced from advanced NdFeB material, which, with dimensions of Ø5x10 mm, guarantees the highest energy density. The MW 5x10 / N38 model is characterized by high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.56 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its triple-layer 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 DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 5.45 N with a weight of only 1.47 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 automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø5x10), 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 5 mm and height 10 mm. The key parameter here is the lifting capacity amounting to approximately 0.56 kg (force ~5.45 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.
Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 5 mm. 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 neodymium magnets.

Pros

Besides their tremendous strength, neodymium magnets offer the following advantages:
  • They do not lose power, even over nearly 10 years – the reduction in lifting capacity is only ~1% (according to tests),
  • They maintain their magnetic properties even under close interference source,
  • A magnet with a metallic nickel surface is more attractive,
  • Magnetic induction on the working layer of the magnet remains exceptional,
  • 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 molding and adaptation to unique requirements, magnetic components can be modeled in a broad palette of forms and dimensions, which increases their versatility,
  • Huge importance in modern technologies – they are commonly used in hard drives, electric drive systems, advanced medical instruments, as well as other advanced devices.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
  • When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
  • We suggest casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
  • Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these products are able to complicate diagnosis medical when they are in the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting force for a neodymium magnet – what contributes to it?

The force parameter is a measurement result conducted under the following configuration:
  • on a base made of structural steel, effectively closing the magnetic field
  • with a cross-section minimum 10 mm
  • with an ideally smooth contact surface
  • without any clearance between the magnet and steel
  • for force applied at a right angle (in the magnet axis)
  • in neutral thermal conditions

Determinants of lifting force in real conditions

Bear in mind that the magnet holding will differ depending on the following factors, starting with the most relevant:
  • Gap between magnet and steel – 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.
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, 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 passes through the material instead of generating force.
  • Metal type – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
  • Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal weaken the grip.
  • Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.

H&S for magnets
Operating temperature

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

Magnetic media

Data protection: Strong magnets can damage payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).

Pacemakers

Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

GPS Danger

A strong magnetic field interferes with the operation of compasses in smartphones and navigation systems. Do not bring magnets close to a smartphone to prevent breaking the sensors.

Bodily injuries

Big blocks can break fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.

Handling rules

Use magnets with awareness. Their immense force can shock even experienced users. Be vigilant and do not underestimate their power.

Allergy Warning

A percentage of the population have a sensitization to nickel, which is the typical protective layer for neodymium magnets. Extended handling can result in dermatitis. We suggest wear safety gloves.

Combustion hazard
