Pulling power drops sharply with every subsequent millimeter of distance. Note that even the smallest gap (e.g., contamination, varnish, rust) noticeably diminishes the holding power. Magnets hold strongest at the point of direct contact; gap drastically cuts the power. See how flashily the load capacity drop, when the product does not adhere tightly to the metal substrate. When designing the arrangement, eliminate additional spacers.

The table below defines the approximate force necessary to start the sliding of the magnet down on a vertical metal surface (assuming typical friction coefficient). This parameter depends on the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 14x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.83 kg / 1.83 lbs 828.0 g / 8.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.55 kg / 1.22 lbs 552.0 g / 5.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.28 kg / 0.61 lbs 276.0 g / 2.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.38 kg / 3.04 lbs 1380.0 g / 13.5 N

When hanging a element on a vertical surface (e.g., a board), it will maintain only about 20%-30% of its nominal power. Gravitational force and a low friction coefficient mean that products slip easier than they pull off. Designing a wall mount? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a noticeably lighter load. Using a rubber pad can effectively raise the stability.

12 mm	100%	2.76 kg / 6.08 lbs 2760.0 g / 27.1 N

A too thin steel is not enough to absorb the entire magnetic field, which squanders power of the holder. Should you install a neodymium to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To utilize the maximum of this neodymium's power, you require a sufficiently solid piece of metal. The material oversaturation causes that on delicate walls (e.g., car bodies), the magnet works worse. We advise picking the steel dimension based on the following data.

Ordinary NdFeB products irreversibly lose strength after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly destroy this product. With every degree above norm, the magnet's capacity briefly lowers. Refrain from using this product close to ovens higher than its safe range. Exceeding the critical threshold will result in destruction of magnetic properties.

*Important note: Temperature resistance is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) 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 magnets attract each other 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 operation. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is huge. The levitation is marginally weaker than the attraction, but still impressive.
*Field value for N-N configuration is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Estimates refer to shear force of dual matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a real danger to electronics as well as medical implants. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - collision effects
MW 14x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	28.91 km/h (8.03 m/s)	0.11 J
30 mm	49.34 km/h (13.71 m/s)	0.32 J
50 mm	63.69 km/h (17.69 m/s)	0.54 J
100 mm	90.07 km/h (25.02 m/s)	1.08 J

Neodymium magnets are delicate – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can cause material chips or injury to fingers. 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. Use safety goggles when playing 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!

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

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

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) severely weakens 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) = 0.31

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 offered product is an exceptionally strong cylindrical magnet, composed of durable NdFeB material, which, at dimensions of Ø14x3 mm, guarantees optimal power. The MW 14x3 / N38 component is characterized by high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 2.76 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 27.06 N with a weight of only 3.46 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision 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 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 the strongest magnets in the same volume (Ø14x3), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 14 mm and height 3 mm. The key parameter here is the lifting capacity amounting to approximately 2.76 kg (force ~27.06 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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 14 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 Nd₂Fe₁₄B magnets.

Strengths

Besides their immense magnetic power, neodymium magnets offer the following advantages:

They retain magnetic properties for around ten years – the loss is just ~1% (according to analyses),
Magnets effectively resist against loss of magnetization caused by external fields,
A magnet with a metallic nickel surface looks better,
Magnets exhibit exceptionally strong magnetic induction on the working surface,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
Possibility of detailed forming as well as adjusting to precise needs,
Universal use in future technologies – they are commonly used in HDD drives, motor assemblies, medical equipment, and multitasking production systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting 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 experience a drop in force. 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
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex forms.
Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small elements of these magnets can be problematic in diagnostics medical when they are in the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Maximum lifting force for a neodymium magnet – what affects it?

The lifting capacity listed is a measurement result performed under specific, ideal conditions:

with the contact of a sheet made of special test steel, ensuring maximum field concentration
possessing a thickness of min. 10 mm to avoid saturation
with an ground contact surface
with zero gap (no coatings)
for force applied at a right angle (pull-off, not shear)
in temp. approx. 20°C

Magnet lifting force in use – key factors

In practice, the actual holding force is determined by many variables, ranked from the most important:

Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Angle of force application – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

H&S for magnets

Warning for heart patients

For implant holders: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or request help to work with the magnets.

Do not underestimate power

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

Skin irritation risks

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease handling magnets and wear gloves.

Mechanical processing

Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Eye protection

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

Safe distance

Equipment safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).

Threat to navigation

Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.

Pinching danger

Protect your hands. Two powerful magnets will join immediately with a force of massive weight, crushing anything in their path. Be careful!

Permanent damage

Avoid heat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).

This is not a toy

Only for adults. Tiny parts can be swallowed, leading to serious injuries. Keep away from kids and pets.
