Pulling power drops drastically with every subsequent millimeter of gap. Remember that even a microscopic distance (e.g., contamination, paint, dust) strongly weakens the grip. Magnets work optimally in perfect adhesion; air break drastically cuts the power. Analyze how rapidly the parameters drop, when the magnet does not adhere flatly to the metal substrate. When designing the assembly, eliminate additional spacers.

This section indicates the estimated shear load needed to initiate the downward movement of the magnet downwards along a upright steel wall (assuming standard friction coefficient). This parameter is a function of the air gap between the magnet and the metal.

When mounting a holder on a upright plane (e.g., a car body), it will only hold only about 1/5 of its maximum pull force. Gravitational force and a weak degree of grip cause that holders slide down faster than they pull off. Planning a hanger? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a significantly smaller cargo. Utilizing a rubberized pad can drastically increase the grip.

A too thin steel cannot focus the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a too thin substrate, the flux will pass right through and the attraction force will be weaker. To achieve the maximum of this magnet's power, you need a suitably thick piece of metal. The material oversaturation means that on delicate walls (e.g., thin profiles), the magnet works worse. We suggest choosing the steel dimension according to the table below.

Classic neodymiums irreversibly lose strength past the thermal threshold. Protect against heat – high temperature can permanently destroy this product. As the temperature rises, the neodymium's power temporarily lowers. Do not use this product close to heaters higher than its safe range. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) are more susceptible to demagnetization sooner than taller cylinders. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. The connection of two magnets produces a massive flux and a further horizon of action. Want to build a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the collision energy is massive. The levitation is marginally weaker than the connection force, but still large.
*Field value between like poles is approximately ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Note: Results demonstrate sliding force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a serious hazard to IT equipment as well as pacemakers. These magnets generate a field that disrupts operation of sensitive medical devices. Notice: the unseen radiation penetrates the body and plastic. Exceptional care must be taken by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a strong collision with metal risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or injury to fingers. Be sure to control the product during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when working with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

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

1. Vertical hold

*Warning: On a vertical wall, the magnet holds merely approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

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

3. Thermal stability

*For N38 material, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.31

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 a very strong rod magnet, composed of durable NdFeB material, which, with dimensions of Ø4x10 mm, guarantees the highest energy density. This specific item features high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.32 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 3.16 N with a weight of only 0.94 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. 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 durability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø4x10), 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 Ø4x10 mm, which, at a weight of 0.94 g, makes it an element with impressive magnetic energy density. The value of 3.16 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.94 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 10 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 as well as weaknesses of neodymium magnets.

Strengths

Besides their durability, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
Magnets perfectly resist against loss of magnetization caused by foreign field sources,
By applying a lustrous layer of nickel, the element has an modern look,
The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of exact forming as well as optimizing to concrete needs,
Huge importance in modern technologies – they are used in HDD drives, drive modules, medical devices, and other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in small systems

Cons

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets suffer a drop in power. 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
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in creating nuts and complicated shapes in magnets, we propose using a housing - magnetic mount.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical after entering the body.
With mass production the cost of neodymium magnets can be a barrier,

Holding force characteristics

Maximum holding power of the magnet – what it depends on?

Magnet power was defined for optimal configuration, including:

with the use of a sheet made of special test steel, ensuring full magnetic saturation
with a cross-section no less than 10 mm
characterized by lack of roughness
with total lack of distance (without impurities)
for force acting at a right angle (in the magnet axis)
at conditions approx. 20°C

Impact of factors on magnetic holding capacity in practice

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

Gap (between the magnet and the metal), as even a tiny clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Base massiveness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped to the other side.
Steel grade – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.

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 small distance between the magnet’s surface and the plate reduces the holding force.

Warnings

Hand protection

Large magnets can crush fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.

Nickel allergy

Some people experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Prolonged contact might lead to an allergic reaction. We suggest use protective gloves.

Data carriers

Data protection: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Product not for children

NdFeB magnets are not toys. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates urgent medical intervention.

Flammability

Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.

Heat sensitivity

Avoid heat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Respect the power

Use magnets consciously. Their huge power can shock even experienced users. Be vigilant and respect their force.

Shattering risk

Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Medical implants

Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Impact on smartphones

Be aware: neodymium magnets produce a field that confuses sensitive sensors. Keep a separation from your phone, device, and navigation systems.
