Pulling power drops significantly with every mm of distance. Keep in mind that even a very thin break (e.g., dirt, varnish, veneer) significantly diminishes the holding power. Neodymiums operate optimally during direct contact; distance weakens the force. Notice how rapidly the parameters drop, when the magnet does not adhere flatly to the metal substrate. When calculating the mounting, eliminate additional spacers.

The following data defines the approximate holding capacity sufficient to start the shifting of the magnet downwards along a upright metal surface (considering standard friction coefficient). This parameter is relative to the air gap between the magnet and the metal.

When mounting a magnet on a vertical plane (e.g., a car body), it you can count on only approx. 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip mean that magnets move down easier than they detach. Designing a hanger? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will give way down under a much lighter cargo. Using a rubber coating can significantly raise the stability.

A thin metal plate is unable to focus the full magnetic flux, which wastes potential of the holder. If you attach a powerful product to a too thin substrate, the field will pass right through and the attraction force will be weaker. To achieve 100% of this magnet's power, you require a sufficiently solid element of metal. The material oversaturation causes that on sheet metal structures (e.g., car bodies), the product works worse. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products lose power above the temperature limit. Watch out for overheating – excessive heat can permanently destroy this magnet. With every degree above norm, the magnet's force temporarily decreases. Refrain from using this magnet close to heaters higher than its operating temperature limit. Exceeding the critical threshold will lead to irreversible degradation of magnetism.

*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) risk losing magnetic properties under lower heat stress compared to rod magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two magnets interact from a wider radius than a neodymium and metal combination. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of operation. Designing a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the pinch force is huge. The levitation is marginally weaker than the connection force, but still large.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint between the magnets (due to field cancellation).
Note: Calculations show shear force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field is a serious hazard to IT equipment as well as medical implants. These NdFeB products generate a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field penetrates the body and glass. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can cause material chips or painful pinches to skin. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when playing with powerful specimens.

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Efficiency vs thickness

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

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.71

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 offered product is an extremely powerful rod magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø12x8 mm, guarantees optimal power. The MW 12x8 / N38 component boasts high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 4.93 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 48.32 N with a weight of only 6.79 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way 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 industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are strong enough for 90% 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 (Ø12x8), 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 8 mm. The value of 48.32 N means that the magnet is capable of holding a weight many times exceeding its own mass of 6.79 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 8 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Strengths as well as weaknesses of neodymium magnets.

Strengths

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

They retain attractive force for almost 10 years – the loss is just ~1% (in theory),
Neodymium magnets remain exceptionally resistant to demagnetization caused by magnetic disturbances,
By covering with a lustrous layer of nickel, the element has an aesthetic look,
They are known for high magnetic induction at the operating surface, which improves attraction properties,
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...
Possibility of exact machining and adapting to concrete requirements,
Significant place in high-tech industry – they are used in HDD drives, motor assemblies, precision medical tools, and multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions

Weaknesses

Characteristics of disadvantages of neodymium magnets and ways of using them

Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
We recommend a housing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex forms.
Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, small components of these products are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum holding power of the magnet – what contributes to it?

The lifting capacity listed is a result of laboratory testing conducted under standard conditions:

using a sheet made of high-permeability steel, functioning as a circuit closing element
whose thickness reaches at least 10 mm
with an polished contact surface
without the slightest air gap between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at ambient temperature room level

Impact of factors on magnetic holding capacity in practice

Bear in mind that the working load may be lower influenced by the following factors, in order of importance:

Distance (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Chemical composition of the base – mild steel attracts best. Alloy steels decrease magnetic permeability and holding force.
Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Precautions when working with NdFeB magnets

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness happens, immediately stop handling magnets and wear gloves.

Flammability

Dust generated during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Threat to electronics

Powerful magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.

Magnet fragility

Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.

Safe operation

Handle magnets consciously. Their powerful strength can shock even professionals. Stay alert and respect their force.

Magnetic interference

Be aware: neodymium magnets produce a field that confuses precision electronics. Maintain a safe distance from your mobile, tablet, and GPS.

Do not overheat magnets

Monitor thermal conditions. Exposing the magnet to high heat will ruin its properties and pulling force.

This is not a toy

NdFeB magnets are not intended for children. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.

Life threat

Patients with a ICD have to maintain an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.

Bone fractures

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