Grip strength decreases drastically with every mm of gap. Keep in mind that even a microscopic distance (e.g., contamination, varnish, rust) significantly weakens the grip. Magnetic products hold strongest during direct contact; gap weakens the power. Observe how flashily the load capacity plummet, when the product does not adhere directly to the steel surface. When designing the mounting, avoid additional spacers.

The table below calculates the approximate weight limit sufficient to initiate the slippage of the magnet downwards on a vertical steel wall (considering standard friction coefficient). This parameter varies with the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MP 20x8x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.17 kg / 4.78 lbs 2166.0 g / 21.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.44 kg / 3.18 lbs 1444.0 g / 14.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.72 kg / 1.59 lbs 722.0 g / 7.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.61 kg / 7.96 lbs 3610.0 g / 35.4 N

When mounting a element on a upright wall (e.g., a board), it will maintain only approx. 20%-30% of nominal attraction strength. Gravitational force as well as a low friction coefficient influence the fact that holders slide down faster than they detach. Designing a wall mount? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a noticeably lighter cargo. Application of an anti-slip coating can significantly improve the result.

12 mm	100%	7.22 kg / 15.92 lbs 7220.0 g / 70.8 N

A thin metal plate is not enough to absorb the entire magnetic field, which squanders power of the holder. If you install a neodymium to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To utilize 100% of this neodymium's potential, you need a suitably thick piece of steel. The saturation phenomenon means that on delicate walls (e.g., thin profiles), the product shows lower pull force. We advise picking the steel dimension based on the following data.

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly demagnetize this product. As the temperature rises, the neodymium's force momentarily decreases. Avoid using this magnet close to heaters exceeding its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. The danger warning in the table signals permanent field degradation for this particular item.

Two magnetic products interact from a wider radius than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of performance. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a steel. Be careful that when bringing together two magnets, the collision energy is massive. The repulsion force is slightly lower than the connection force, but still large.
*Field value for N-N configuration drops to ~0 Gs at the midpoint between the magnets (due to field cancellation).
Note: Estimates demonstrate friction force of dual same magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a large risk to electronic devices as well as medical implants. These neodymiums generate a flux that destroys function of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and plastic. Special caution must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Kinetic force can cause material chips or injury to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when handling with powerful specimens.

Warning: 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. 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 retains only ~20% of its perpendicular strength.

2. Plate thickness effect

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

3. Thermal stability

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.14

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 ring magnet with a hole MP 20x8x6 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. This product with a force of 7.22 kg works great as a cabinet closure, speaker holder, or mounting element in devices.

This is a crucial issue when working with model MP 20x8x6 / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable and inelastic. One turn too many can destroy the magnet, so do it slowly. It's a good idea to use a flexible washer under the screw head, which will cushion the stresses. Remember: cracking during assembly results from material properties, not a product defect.

These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but is not sufficient for rain. In the place of the mounting hole, the coating is thinner and easily scratched when tightening the screw, which will become a corrosion focus. If you must use it outside, paint it with anti-corrosion paint after mounting.

A screw or bolt with a thread diameter smaller than 8 mm fits this model. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Always check that the screw head is not larger than the outer diameter of the magnet (20 mm), so it doesn't protrude beyond the outline.

It is a magnetic ring with a diameter of 20 mm and thickness 6 mm. The pulling force of this model is an impressive 7.22 kg, which translates to 70.81 N in newtons. The mounting hole diameter is precisely 8 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Benefits

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
They have excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
Thanks to the shiny finish, the layer of nickel, gold-plated, or silver-plated gives an visually attractive appearance,
The surface of neodymium magnets generates a unique magnetic field – this is a key 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...
Thanks to modularity in shaping and the capacity to customize to complex applications,
Significant place in future technologies – they are commonly used in data components, electromotive mechanisms, advanced medical instruments, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices

Weaknesses

Disadvantages of neodymium magnets:

At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
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 as well as corrosion.
We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical in case of swallowing.
With mass production the cost of neodymium magnets can be a barrier,

Lifting parameters

Maximum holding power of the magnet – what it depends on?

The force parameter is a theoretical maximum value executed under the following configuration:

using a sheet made of high-permeability steel, serving as a circuit closing element
with a thickness of at least 10 mm
with an polished contact surface
with direct contact (no impurities)
for force applied at a right angle (pull-off, not shear)
in stable room temperature

Determinants of lifting force in real conditions

During everyday use, the actual holding force results from many variables, presented from crucial:

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Direction of force – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Base massiveness – too thin sheet does not close the flux, causing part of the power to be lost to the other side.
Material type – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
Surface finish – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate reduces the holding force.

Precautions when working with NdFeB magnets

Machining danger

Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.

Magnetic interference

Note: neodymium magnets produce a field that disrupts precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.

Conscious usage

Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Product not for children

Product intended for adults. Tiny parts can be swallowed, leading to severe trauma. Keep away from children and animals.

Allergy Warning

Nickel alert: The nickel-copper-nickel coating contains nickel. If redness happens, cease working with magnets and use protective gear.

Health Danger

People with a ICD should keep an safe separation from magnets. The magnetic field can stop the functioning of the implant.

Material brittleness

Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.

Data carriers

Avoid bringing magnets close to a wallet, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.

Bone fractures

Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.

Heat sensitivity

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
