Grip strength drops sharply with every mm of spacing. Keep in mind that even a very thin break (e.g., dirt, paint, dust) significantly weakens the grip. Magnetic products operate strongest in perfect adhesion; distance kills the force. Analyze how quickly the parameters fall, when the product does not adhere directly to the steel surface. When planning the arrangement, avoid unnecessary gaps.

The table below shows the approximate weight limit required to cause the sliding of the magnet down along a vertical steel plate (assuming standard friction). This value is a function of the distance between the magnet and the metal.

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 mounting a magnet on a upright surface (e.g., a fridge), it will only hold just about 20%-30% of its nominal power. Gravity and a weak degree of grip mean that magnets slip faster than they detach. Want to create a hanger? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will give way down under a significantly smaller load. Using a rubber layer can significantly raise the stability.

A too thin steel is not enough to absorb the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a thin surface, the field will pass right through and the pull force will drop sharply. To utilize full efficiency of this magnet's potential, you need a suitably thick element of metal. The saturation effect means that on thin elements (e.g., appliance housings), the holder holds weaker. We suggest choosing the steel dimension based on the following data.

Standard neodymium magnets change their properties parameters above the temperature limit. Watch out for overheating – heat can permanently demagnetize this magnet. With increasing heat, the neodymium's power momentarily lowers. Refrain from using this magnet near heat sources higher than its operating temperature limit. Too high temperature will cause destruction of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. Warning indicator in the table indicates permanent field degradation for this particular item.

Two strong neodymiums interact from a much further distance than a neodymium and metal setup. Such a system of magnet-to-magnet generates a stronger field and a larger range of action. Designing a solid fastener? Apply two magnets instead of a neodymium and a steel. Remember that when attracting two neodymiums, the collision energy is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*Flux density between like poles is approximately ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Note: Figures refer to shear force of two same magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a large risk to electronic devices as well as medical implants. These neodymiums produce a flux that disrupts operation of digital equipment. Notice: the invisible magnetic field acts through matter and glass. Special caution must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can trigger coating fragments or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Wear safety glasses when handling with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Note: On a vertical wall, the magnet retains only ~20% of its nominal pull.

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) significantly limits the holding force.

3. Power loss vs temp

*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 a very strong cylindrical magnet, composed of durable NdFeB material, which, with dimensions of Ø12x3 mm, guarantees optimal power. This specific item features high dimensional repeatability and industrial build quality, making it an excellent 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 rapid order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 24.43 N with a weight of only 2.54 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability in industry, anaerobic resins 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 frequently chosen standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø12x3), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø12x3 mm, which, at a weight of 2.54 g, makes it an element with impressive magnetic energy density. 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 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 12 mm. 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 diametrically if your project requires it.

Advantages as well as disadvantages of rare earth magnets.

Pros

Besides their high retention, neodymium magnets are valued for these benefits:

They do not lose power, even during nearly 10 years – the decrease in lifting capacity is only ~1% (theoretically),
They are resistant to demagnetization induced by external disturbances,
A magnet with a shiny nickel surface has an effective appearance,
Magnets are characterized by excellent magnetic induction on the working surface,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of detailed modeling as well as adjusting to complex needs,
Wide application in high-tech industry – they are commonly used in magnetic memories, brushless drives, precision medical tools, as well as technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in miniature devices

Limitations

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power 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 resistant to moisture, when using outdoors
Due to limitations in producing nuts and complicated forms in magnets, we propose using casing - magnetic holder.
Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these products are able to complicate diagnosis medical after entering the body.
Due to complex production process, their price is relatively high,

Lifting parameters

Magnetic strength at its maximum – what it depends on?

Magnet power is the result of a measurement for the most favorable conditions, taking into account:

on a base made of mild steel, effectively closing the magnetic field
with a cross-section minimum 10 mm
with an polished contact surface
under conditions of ideal adhesion (metal-to-metal)
under axial force direction (90-degree angle)
in neutral thermal conditions

Impact of factors on magnetic holding capacity in practice

Bear in mind that the working load may be lower depending on elements below, in order of importance:

Clearance – the presence of foreign body (rust, tape, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Angle of force application – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
Steel thickness – too thin sheet does not accept the full field, causing part of the power to be wasted to the other side.
Steel grade – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
Surface quality – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Safety rules for work with neodymium magnets

Swallowing risk

Strictly keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are fatal.

Machining danger

Dust produced during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Health Danger

Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Keep away from electronics

A powerful magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Maintain magnets near a device to avoid damaging the sensors.

Conscious usage

Handle magnets consciously. Their immense force can surprise even experienced users. Be vigilant and respect their force.

Physical harm

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

Protective goggles

Neodymium magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets will cause them cracking into shards.

Safe distance

Intense magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Operating temperature

Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.

Nickel coating and allergies

It is widely known that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, prevent direct skin contact or opt for coated magnets.
