Magnetic force weakens sharply with every subsequent millimeter of spacing. Remember that even a microscopic distance (e.g., dirt, varnish, rust) strongly reduces the pull force. Neodymiums hold most effectively at the point of direct contact; gap nullifies the power. See how quickly the pull force fall, when the magnet does not touch tightly to the metal substrate. When planning the assembly, avoid additional spacers.

The table below defines the theoretical holding capacity sufficient to start the slippage of the magnet vertically on a upright steel plate (assuming typical friction). This value varies with the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.12 kg / 0.26 pounds 120.0 g / 1.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.08 kg / 0.18 pounds 80.0 g / 0.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.09 pounds 40.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.20 kg / 0.44 pounds 200.0 g / 2.0 N

When mounting a holder on a upright surface (e.g., a fridge), it will only hold only approx. 20%-30% of its nominal power. Gravity and a weak degree of grip cause that products slip faster than they detach. Designing a wall mount? Note that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the element will slide down under a significantly smaller weight. Application of an anti-slip layer can drastically raise the stability.

A thin metal plate is incapable of conduct the entire magnetic field, which weakens actual performance of the holder. Should you install a neodymium to a thin surface, the field will penetrate right through and the pull force will drop sharply. To utilize the maximum of this neodymium's power, you require a sufficiently solid backing of metal. The saturation effect causes that on delicate walls (e.g., thin profiles), the holder works worse. We advise picking the steel dimension based on the following data.

Table 5: Thermal resistance (material behavior) - resistance threshold

Classic neodymiums irreversibly lose power after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly demagnetize this magnet. With increasing heat, the neodymium's force momentarily lowers. Do not use this product in hot environments higher than its safe range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Engineering note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) are more susceptible to demagnetization under lower heat stress than long magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and sheet setup. The setup of two magnets creates a more powerful interaction and a larger range of operation. Planning to create a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the pinch force is extreme. The levitation is marginally weaker than the attraction, but still impressive.
*Field value for N-N configuration drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Important: Calculations show sliding force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field poses a large risk to electronics as well as medical implants. These neodymiums generate a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and glass. Exceptional care must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MW 9.5x1 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	27.80 km/h (7.72 m/s)	0.02 J
30 mm	47.99 km/h (13.33 m/s)	0.05 J
50 mm	61.95 km/h (17.21 m/s)	0.08 J
100 mm	87.61 km/h (24.34 m/s)	0.16 J

Magnetic elements are delicate – a collision with steel can result in shattering. Control the attraction moment – a neodymium left loose turns into a projectile. Impact energy can cause material chips or injury to skin. 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. Use safety goggles when working with powerful specimens.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Caution: On a vertical wall, the magnet holds merely a fraction of its max power.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Thermal stability

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.16

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 an exceptionally strong cylinder magnet, composed of modern NdFeB material, which, with dimensions of Ø9.5x1 mm, guarantees optimal power. This specific item features a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 0.40 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 3.96 N with a weight of only 0.53 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets N38 are strong enough for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø9.5x1), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 9.5 mm and height 1 mm. The value of 3.96 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.53 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, 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 9.5 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 through the diameter if your project requires it.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
Magnets very well resist against loss of magnetization caused by external fields,
Thanks to the shimmering finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an modern appearance,
The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
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...
Thanks to versatility in designing and the capacity to adapt to individual projects,
Fundamental importance in innovative solutions – they serve a role in magnetic memories, brushless drives, advanced medical instruments, also technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Limitations

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in creating threads and complex forms in magnets, we propose using cover - magnetic holder.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical in case of swallowing.
With mass production the cost of neodymium magnets is economically unviable,

Holding force characteristics

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

Information about lifting capacity was determined for the most favorable conditions, taking into account:

on a plate made of mild steel, perfectly concentrating the magnetic flux
with a cross-section no less than 10 mm
characterized by smoothness
under conditions of ideal adhesion (metal-to-metal)
under vertical application of breakaway force (90-degree angle)
in stable room temperature

Lifting capacity in practice – influencing factors

During everyday use, the real power is determined by several key aspects, listed from crucial:

Air gap (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, rust or debris).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be lost into the air.
Chemical composition of the base – mild steel gives the best results. Alloy steels lower magnetic permeability and holding force.
Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the holding force.

Precautions when working with neodymium magnets

Threat to navigation

Remember: rare earth magnets produce a field that confuses precision electronics. Keep a separation from your mobile, tablet, and GPS.

Operating temperature

Control the heat. Exposing the magnet to high heat will destroy its properties and strength.

Skin irritation risks

Some people suffer from a contact allergy to nickel, which is the common plating for neodymium magnets. Prolonged contact may cause an allergic reaction. We suggest wear protective gloves.

Do not underestimate power

Handle magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and do not underestimate their force.

Keep away from computers

Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).

This is not a toy

Neodymium magnets are not suitable for play. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and necessitates immediate surgery.

Dust explosion hazard

Machining of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Finger safety

Large magnets can break fingers in a fraction of a second. Never place your hand between two strong magnets.

Medical interference

Individuals with a heart stimulator should maintain an safe separation from magnets. The magnetism can interfere with the operation of the life-saving device.

Risk of cracking

Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
