Grip strength drops drastically per each millimeter of gap. Keep in mind that every additional insulation layer (e.g., dirt, paint, veneer) strongly diminishes the holding power. Neodymiums hold strongest at the point of direct contact; air break nullifies the power. See how quickly the parameters plummet, when the product does not touch directly to the metal substrate. When designing the mounting, eliminate unnecessary gaps.

This section indicates the approximate holding capacity sufficient to cause the sliding of the magnet vertically along a upright steel plate (considering standard friction coefficient). The holding force depends on the distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MW 8x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.65 kg / 1.44 pounds 651.0 g / 6.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.43 kg / 0.96 pounds 434.0 g / 4.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 0.48 pounds 217.0 g / 2.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.09 kg / 2.39 pounds 1085.0 g / 10.6 N

When hanging a holder on a vertical wall (e.g., a fridge), it will only hold only about 1/5 of its maximum pull force. Gravitational force and a low friction coefficient cause that magnets slide down easier than they pull off. Want to create a vertical fastening? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a much lighter weight. Application of an anti-slip coating can drastically increase the grip.

A too thin steel cannot take in the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To squeeze full efficiency of this magnet's potential, you need a suitably thick piece of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the holder holds weaker. We advise picking the steel cross-section based on the following data.

Ordinary NdFeB products change their properties strength past the thermal threshold. Avoid high temperatures – high temperature can permanently destroy this product. With increasing heat, the neodymium's capacity briefly drops. Do not use this product close to heaters exceeding its working range. Too high temperature will lead to destruction of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) risk losing magnetic properties under lower heat stress than long magnets. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two magnetic products interact from a wider radius than a magnet and steel setup. The setup of two magnets generates a stronger field and a wider radius of performance. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the impact force is huge. The levitation is a bit weaker than the attraction, but still significant.
*Field value between like poles reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Important: Estimates demonstrate friction force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Protective zones (electronics) - warnings

Powerful magnet radiation poses a large risk to IT equipment and pacemakers. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation acts through matter and glass. Special caution must be taken by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - warning
MW 8x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	34.31 km/h (9.53 m/s)	0.09 J
30 mm	59.35 km/h (16.49 m/s)	0.26 J
50 mm	76.62 km/h (21.28 m/s)	0.43 J
100 mm	108.35 km/h (30.10 m/s)	0.85 J

Magnetic elements are delicate – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can cause material chips or injury to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when working with large magnets.

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 holds only approx. 20-30% of its max power.

2. Efficiency vs thickness

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.68

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 extremely powerful cylindrical magnet, composed of advanced NdFeB material, which, with dimensions of Ø8x5 mm, guarantees optimal power. This specific item boasts high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 2.17 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 21.31 N with a weight of only 1.88 g, this cylindrical magnet is indispensable in electronics 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 professional component. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are suitable for the majority 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 (Ø8x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 8 mm and height 5 mm. The key parameter here is the lifting capacity amounting to approximately 2.17 kg (force ~21.31 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 8 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.

Advantages as well as disadvantages of rare earth magnets.

Strengths

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

They do not lose power, even over around ten years – the reduction in power is only ~1% (based on measurements),
They possess excellent resistance to magnetism drop due to opposing magnetic fields,
Thanks to the metallic finish, the layer of nickel, gold-plated, or silver-plated gives an elegant appearance,
They are known for high magnetic induction at the operating surface, which increases their power,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
In view of the ability of precise shaping and customization to unique requirements, neodymium magnets can be produced in a broad palette of geometric configurations, which makes them more universal,
Versatile presence in future technologies – they serve a role in computer drives, drive modules, medical equipment, also modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Limitations

Problematic aspects of neodymium magnets: weaknesses and usage proposals

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as 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 corrode. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in creating nuts and complex shapes in magnets, we recommend using cover - magnetic holder.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products can disrupt the diagnostic process medical when they are in the body.
With budget limitations the cost of neodymium magnets is economically unviable,

Pull force analysis

Highest magnetic holding force – what it depends on?

The specified lifting capacity represents the limit force, recorded under laboratory conditions, meaning:

on a base made of mild steel, effectively closing the magnetic field
whose transverse dimension equals approx. 10 mm
with an ground contact surface
with direct contact (no impurities)
during pulling in a direction perpendicular to the mounting surface
at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

Real force is affected by specific conditions, including (from most important):

Distance (between the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
Chemical composition of the base – mild steel gives the best results. Alloy steels lower magnetic permeability and holding force.
Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Safe handling of NdFeB magnets

Permanent damage

Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.

Electronic devices

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

Danger to the youngest

These products are not intended for children. Accidental ingestion of a few magnets may result in them attracting across intestines, which poses a critical condition and requires immediate surgery.

Handling rules

Be careful. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can move away.

Medical implants

Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Allergic reactions

Studies show that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from direct skin contact and select coated magnets.

Bone fractures

Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Compass and GPS

Navigation devices and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Shattering risk

Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them breaking into shards.

Dust explosion hazard

Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.

Danger! More info about hazards in the article: Magnet Safety Guide.
