Magnetic force drops drastically with every subsequent millimeter of gap. Keep in mind that even the smallest gap (e.g., dirt, paint, rust) strongly reduces the pull force. Magnets operate optimally in perfect adhesion; gap drastically cuts the power. Analyze how rapidly the load capacity drop, when the magnet does not adhere flatly to the steel surface. When designing the arrangement, avoid redundant distances.

This section calculates the theoretical force necessary to cause the sliding of the magnet vertically on a upright steel plate (assuming standard friction). The holding force is relative to the distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 12x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.75 kg / 1.65 LBS 747.0 g / 7.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.50 kg / 1.10 LBS 498.0 g / 4.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.25 kg / 0.55 LBS 249.0 g / 2.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.25 kg / 2.74 LBS 1245.0 g / 12.2 N

When hanging a magnet on a upright plane (e.g., a fridge), it you can count on only about 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip cause that magnets slide down easier than they pop off the substrate. Designing a wall mount? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a significantly smaller cargo. Application of an anti-slip layer can significantly improve the result.

A thin sheet is not enough to absorb the entire magnetic field, which squanders power of the magnet. If you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To utilize full efficiency of this neodymium's potential, you need a suitably thick element of metal. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the magnet shows lower pull force. We recommend selecting the steel thickness from these parameters.

Standard neodymium magnets lose parameters above the temperature limit. Avoid high temperatures – excessive heat can irreversibly demagnetize this magnet. As the temperature rises, the magnet's power briefly lowers. Avoid using this magnet close to ovens exceeding its safe range. Too high temperature will lead to permanent loss of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) are more susceptible to demagnetization sooner than taller cylinders. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and sheet setup. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a steel. Remember that when attracting two neodymiums, the pinch force is huge. The repulsion force is marginally weaker than the attraction, but still impressive.
*Flux density between like poles drops to ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Attention: Results demonstrate friction force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a real danger to IT equipment and medical implants. These NdFeB products produce a flux that destroys function of digital equipment. Remember: the unseen radiation acts through matter and glass. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a strong collision with metal risks their cracking. Control the attraction moment – a neodymium left loose turns into a projectile. Kinetic force can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when handling with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Warning: On a vertical surface, the magnet holds merely ~20% of its perpendicular strength.

2. Steel thickness impact

*Thin metal sheet (e.g. computer 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) = 0.35

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.

This product is an incredibly powerful cylindrical magnet, produced from advanced NdFeB material, which, at dimensions of Ø12x3 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 2.49 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 24.43 N with a weight of only 2.54 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 12.1 mm) using epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø12x3), 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 12 mm and height 3 mm. The value of 24.43 N means that the magnet is capable of holding a weight many times exceeding its own mass of 2.54 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 3 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.

Strengths and weaknesses of neodymium magnets.

Advantages

Apart from their strong magnetism, neodymium magnets have these key benefits:

Their power remains stable, and after around ten years it decreases only by ~1% (according to research),
They show high resistance to demagnetization induced by external field influence,
By covering with a reflective coating of gold, the element gains an elegant look,
Magnetic induction on the working layer of the magnet turns out to be maximum,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to the potential of precise forming and customization to specialized needs, neodymium magnets can be produced in a wide range of geometric configurations, which increases their versatility,
Significant place in advanced technology sectors – they are commonly used in magnetic memories, electromotive mechanisms, medical devices, as well as modern systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Weaknesses

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We recommend cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum lifting capacity of the magnet – what it depends on?

Breakaway force was determined for optimal configuration, including:

on a block made of mild steel, effectively closing the magnetic flux
possessing a thickness of min. 10 mm to avoid saturation
characterized by even structure
under conditions of gap-free contact (surface-to-surface)
under vertical force direction (90-degree angle)
in neutral thermal conditions

Lifting capacity in real conditions – factors

Real force is influenced by specific conditions, including (from most important):

Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Direction of force – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the load capacity.

Safety rules for work with neodymium magnets

Medical implants

For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Product not for children

Neodymium magnets are not intended for children. Eating a few magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.

Bone fractures

Large magnets can smash fingers instantly. Under no circumstances put your hand between two strong magnets.

Do not overheat magnets

Do not overheat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).

Fire risk

Fire hazard: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.

Immense force

Handle magnets consciously. Their huge power can shock even professionals. Be vigilant and do not underestimate their force.

Protective goggles

NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets will cause them cracking into shards.

Skin irritation risks

Studies show that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact and opt for versions in plastic housing.

Keep away from electronics

Remember: neodymium magnets produce a field that disrupts precision electronics. Keep a separation from your phone, device, and GPS.

Electronic hazard

Intense magnetic fields can destroy records on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.

Caution! Learn more about risks in the article: Magnet Safety Guide.
