Pulling power decreases sharply per each millimeter of gap. Keep in mind that even the smallest gap (e.g., contamination, varnish, dust) strongly diminishes the holding power. Magnets work strongest at the point of direct contact; gap drastically cuts the power. Notice how rapidly the load capacity fall, when the product does not adhere tightly to the steel surface. When designing the mounting, avoid unnecessary gaps.

The following data presents the estimated weight limit necessary to cause the downward movement of the magnet downwards against a vertical steel wall (considering standard friction coefficient). The holding force is a function of the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MW 12x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.26 kg / 0.58 pounds 261.0 g / 2.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.17 kg / 0.38 pounds 174.0 g / 1.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.09 kg / 0.19 pounds 87.0 g / 0.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.44 kg / 0.96 pounds 435.0 g / 4.3 N

When hanging a magnet on a vertical plane (e.g., a fridge), it you can count on only approx. 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip mean that products slide down faster than they detach. Designing a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a significantly smaller load. Utilizing a rubberized pad can drastically improve the result.

12 mm	100%	0.87 kg / 1.92 pounds 870.0 g / 8.5 N

A thin metal plate is unable to take in the entire magnetic field, which wastes potential of the holder. Should you install a neodymium to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To utilize full efficiency of this neodymium's power, you need a suitably thick piece of metal. The material oversaturation means that on thin elements (e.g., thin profiles), the product works worse. We recommend selecting the steel cross-section from these parameters.

Classic neodymiums lose strength above the temperature limit. Protect against heat – high temperature can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's force momentarily drops. Refrain from using this product close to heaters higher than its operating temperature limit. Ignoring the limit will lead to permanent loss of magnetism.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) are more susceptible to demagnetization sooner than long magnets. Red status in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and sheet setup. The connection of two magnets generates a stronger field and a further horizon of action. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is extreme. The repulsion force is marginally weaker than the attraction, but still impressive.
*Field value for N-N configuration is approximately ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Attention: Calculations apply to sliding force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronic devices and pacemakers. These NdFeB products produce a flux that destroys function of sensitive medical devices. Notice: the unseen radiation penetrates the body and housings. Increased vigilance must be taken by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Magnetic elements are delicate – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Impact energy can cause material chips or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Use safety goggles when working with large magnets.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

In water, the magnet feels stronger thanks to Archimedes' principle. 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 wall, the magnet retains merely approx. 20-30% of its max power.

2. Plate thickness effect

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

3. Heat tolerance

*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) = 0.19

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 presented product is an exceptionally strong rod magnet, produced from durable NdFeB material, which, at dimensions of Ø12x1.5 mm, guarantees maximum efficiency. This specific item is characterized by an accuracy of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.87 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 8.51 N with a weight of only 1.27 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 12.1 mm) using epoxy glues. To ensure long-term durability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø12x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø12x1.5 mm, which, at a weight of 1.27 g, makes it an element with impressive magnetic energy density. The value of 8.51 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.27 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 1.5 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized through the diameter if your project requires it.

Advantages as well as disadvantages of rare earth magnets.

Benefits

In addition to their pulling strength, neodymium magnets provide the following advantages:

They retain full power for around ten years – the drop is just ~1% (in theory),
They possess excellent resistance to magnetism drop as a result of external magnetic sources,
The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Neodymium magnets achieve maximum magnetic induction on a contact point, which ensures high operational effectiveness,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Thanks to the potential of free molding and adaptation to individualized needs, neodymium magnets can be produced in a variety of forms and dimensions, which amplifies use scope,
Fundamental importance in advanced technology sectors – they serve a role in hard drives, motor assemblies, diagnostic systems, and technologically advanced constructions.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complex shapes in magnets, we propose using cover - magnetic mount.
Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small elements of these devices can complicate diagnosis medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Best holding force of the magnet in ideal parameters – what affects it?

The lifting capacity listed is a measurement result conducted under the following configuration:

on a block made of mild steel, perfectly concentrating the magnetic field
possessing a massiveness of at least 10 mm to avoid saturation
with an ground contact surface
with zero gap (without paint)
for force applied at a right angle (in the magnet axis)
at ambient temperature room level

Magnet lifting force in use – key factors

Please note that the application force may be lower depending on the following factors, in order of importance:

Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Steel grade – ideal substrate is pure iron steel. Hardened steels may attract less.
Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the load capacity.

Safety rules for work with NdFeB magnets

Medical interference

People with a pacemaker should maintain an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.

Material brittleness

Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.

Do not overheat magnets

Do not overheat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).

Combustion hazard

Powder produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Crushing risk

Watch your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!

This is not a toy

NdFeB magnets are not toys. Swallowing several magnets may result in them attracting across intestines, which constitutes a direct threat to life and necessitates urgent medical intervention.

Magnetic interference

A powerful magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to avoid damaging the sensors.

Electronic devices

Avoid bringing magnets near a wallet, computer, or screen. The magnetism can destroy these devices and wipe information from cards.

Handling rules

Be careful. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can move away.

Skin irritation risks

A percentage of the population experience a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to an allergic reaction. We recommend use protective gloves.
