Pulling power drops significantly with every subsequent millimeter of distance. Keep in mind that even a very thin break (e.g., contamination, paint, dust) significantly diminishes the holding power. Magnetic products hold most effectively at the point of direct contact; gap nullifies the force. Notice how rapidly the pull force fall, when the magnet does not touch flatly to the steel surface. When planning the assembly, eliminate redundant distances.

The table below defines the estimated holding capacity necessary to start the shifting of the magnet vertically on a upright metal surface (considering typical friction coefficient). This parameter is a function of the gap size between the magnet and the surface.

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 pounds 150.0 g / 1.5 N

When hanging a holder on a upright wall (e.g., a fridge), it you can count on only approx. 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip cause that products slip faster than they detach. Planning a vertical fastening? Note that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the element will slip down under a significantly smaller weight. Application of an anti-slip pad can effectively increase the grip.

A thin sheet is incapable of conduct the full magnetic flux, which weakens actual performance of the holder. If you attach a powerful product to a too thin substrate, the magnetism will pass right through and the pull force will drop sharply. To utilize the maximum of this magnet's power, you need a suitably thick element of metal. The material oversaturation causes that on sheet metal structures (e.g., appliance housings), the holder holds weaker. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products lose power after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently damage this magnet. With every degree above norm, the neodymium's capacity briefly lowers. Do not use this magnet close to ovens higher than its safe range. Too high temperature will result in destruction of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures compared to rod magnets. Red status in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums interact from a wider radius than a neodymium and metal setup. Such a system of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is massive. The repulsion force is slightly lower than the attraction, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (due to field cancellation).
Important: Figures apply to shear force of dual matching magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a serious hazard to electronic devices as well as medical implants. These NdFeB products generate a field that destroys function of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Magnetic elements are prone to chipping – a collision with steel can result in shattering. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can destroy the magnet or dangerous crushing to fingers. Be sure to control the product during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when handling with powerful specimens.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

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

2. Steel thickness impact

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

3. Thermal stability

*For N38 material, 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) = 0.83

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 ring-shaped magnet MP 5x2.7/1.2x5 C / N38 is created for permanent mounting, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. This product with a force of 0.75 kg works great as a cabinet closure, speaker holder, or mounting element in devices.

This is a crucial issue when working with model MP 5x2.7/1.2x5 C / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable and inelastic. When tightening the screw, you must maintain great sensitivity. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force will cause the ring to crack. It's a good idea to use a rubber spacer 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 does not ensure full waterproofing. In the place of the mounting hole, the coating is thinner and can be damaged when tightening the screw, which will become a corrosion focus. If you must use it outside, paint it with anti-corrosion paint after mounting.

The inner hole diameter determines the maximum size of the mounting element. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Aesthetic mounting requires selecting the appropriate head size.

This model is characterized by dimensions Ø5x5 mm and a weight of 0.69 g. The pulling force of this model is an impressive 0.75 kg, which translates to 7.31 N in newtons. The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 2.7/1.2 mm.

The poles are located on the planes with holes, not on the sides of the ring. In the case of connecting two rings, make sure one is turned the right way. When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Pros

Besides their immense strength, neodymium magnets offer the following advantages:

Their magnetic field remains stable, and after approximately 10 years it drops only by ~1% (theoretically),
Magnets effectively resist against loss of magnetization caused by foreign field sources,
Thanks to the shimmering finish, the surface of Ni-Cu-Ni, gold, or silver gives an modern appearance,
Neodymium magnets create maximum magnetic induction on a small surface, which ensures high operational effectiveness,
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...
Possibility of detailed forming as well as optimizing to specific requirements,
Huge importance in advanced technology sectors – they are utilized in computer drives, electromotive mechanisms, precision medical tools, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in small systems

Weaknesses

Disadvantages of neodymium magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength 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
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in producing nuts and complicated shapes in magnets, we recommend using cover - magnetic holder.
Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small components of these devices are able to be problematic in diagnostics medical after entering the body.
Due to neodymium price, their price is relatively high,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

The declared magnet strength represents the maximum value, obtained under ideal test conditions, namely:

on a block made of structural steel, effectively closing the magnetic flux
possessing a thickness of minimum 10 mm to ensure full flux closure
characterized by smoothness
under conditions of gap-free contact (surface-to-surface)
for force applied at a right angle (pull-off, not shear)
at temperature room level

Key elements affecting lifting force

Effective lifting capacity is influenced by working environment parameters, including (from most important):

Distance (betwixt the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, 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.
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
Steel type – mild steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal environment – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.

Lifting capacity was assessed using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the holding force.

Safe handling of neodymium magnets

Do not drill into magnets

Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.

GPS and phone interference

Be aware: neodymium magnets produce a field that confuses precision electronics. Keep a safe distance from your mobile, device, and navigation systems.

Eye protection

Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.

Data carriers

Avoid bringing magnets near a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Sensitization to coating

Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness happens, cease handling magnets and use protective gear.

Warning for heart patients

Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Thermal limits

Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).

Product not for children

Always store magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are life-threatening.

Hand protection

Pinching hazard: The pulling power is so great that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Powerful field

Handle magnets with awareness. Their huge power can surprise even professionals. Be vigilant and do not underestimate their force.
