Magnetic force drops sharply with every subsequent millimeter of spacing. Remember that even a very thin break (e.g., contamination, varnish, veneer) strongly diminishes the holding power. Magnetic products hold most effectively at the point of direct contact; distance kills the power. See how rapidly the parameters drop, when the product does not adhere directly to the metal substrate. When calculating the arrangement, eliminate unnecessary gaps.

The table below indicates the approximate weight limit required to cause the shifting of the magnet vertically on a upright metal surface (assuming standard friction coefficient). This value is relative to the air gap between the magnet and the metal.

When hanging a holder on a vertical plane (e.g., a board), it will only hold only approx. 20%-30% of its maximum pull force. Gravity and a low friction coefficient influence the fact that holders slip faster than they detach. Planning a hanger? Note that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the holder will slide down under a much lighter weight. Application of an anti-slip pad can effectively raise the stability.

A too thin steel is incapable of focus the entire magnetic field, which wastes potential of the holder. Should you attach a powerful product to a too thin substrate, the field will pass right through and the pull force will drop sharply. To utilize 100% of this magnet's potential, you need a suitably thick backing of steel. The saturation effect means that on delicate walls (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel dimension from these parameters.

Ordinary NdFeB products lose strength past the thermal threshold. Protect against heat – heat can irreversibly damage this magnet. With increasing heat, the magnet's power momentarily drops. Refrain from using this product close to heaters higher than its operating temperature limit. Too high temperature will result in irreversible degradation of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) risk losing magnetic properties sooner than long magnets. The danger warning in the table signals permanent field degradation for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and steel combination. Such a system of magnet-to-magnet generates a stronger field and a further horizon of performance. Want to build a strong closure? Apply two magnets instead of one magnet and a steel. Be careful that when connecting a pair of magnets, the pinch force is huge. The levitation is a bit weaker than the attraction, but still impressive.
*Flux density for N-N configuration is approximately ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Attention: Results refer to friction force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to electronics and medical implants. These magnets produce a flux that destroys function of sensitive medical devices. Be aware: the invisible magnetic field passes through tissues and glass. Special caution must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are very brittle – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can destroy the magnet or painful pinches to fingers. Always hold the magnet during installation so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when handling with powerful specimens.

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. Shear force

*Warning: On a vertical wall, the magnet holds only ~20% of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) severely reduces the holding force.

3. Heat tolerance

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.38

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 extremely powerful cylinder magnet, composed of modern NdFeB material, which, at dimensions of Ø10x30 mm, guarantees the highest energy density. The MW 10x30 / N38 model features high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.92 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the high power of 18.79 N with a weight of only 17.67 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using epoxy glues. To ensure long-term durability in automation, anaerobic resins 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 professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø10x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 30 mm. The value of 18.79 N means that the magnet is capable of holding a weight many times exceeding its own mass of 17.67 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 30 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable 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.

Strengths and weaknesses of rare earth magnets.

Pros

Besides their exceptional magnetic power, neodymium magnets offer the following advantages:

Their power remains stable, and after approximately ten years it decreases only by ~1% (theoretically),
Neodymium magnets are distinguished by extremely resistant to loss of magnetic properties caused by magnetic disturbances,
In other words, due to the glossy layer of silver, the element looks attractive,
The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
Possibility of exact machining and adapting to specific applications,
Huge importance in innovative solutions – they serve a role in mass storage devices, electromotive mechanisms, diagnostic systems, as well as multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets experience 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
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
Due to limitations in creating threads and complex forms in magnets, we propose using cover - magnetic mechanism.
Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

Information about lifting capacity is the result of a measurement for ideal contact conditions, including:

with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
whose transverse dimension is min. 10 mm
characterized by smoothness
with total lack of distance (no coatings)
for force applied at a right angle (pull-off, not shear)
at room temperature

Determinants of practical lifting force of a magnet

Real force impacted by working environment parameters, such as (from priority):

Distance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Load vector – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Material composition – not every steel reacts the same. High carbon content weaken the attraction effect.
Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet and the plate lowers the load capacity.

Safe handling of NdFeB magnets

Nickel allergy

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop working with magnets and use protective gear.

Crushing force

Danger of trauma: The attraction force is so great that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Fire risk

Powder generated during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Heat sensitivity

Control the heat. Heating the magnet to high heat will destroy its properties and strength.

Electronic devices

Intense magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.

Warning for heart patients

Individuals with a ICD have to maintain an large gap from magnets. The magnetic field can interfere with the functioning of the implant.

Magnets are brittle

NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them shattering into shards.

Product not for children

Absolutely store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.

Do not underestimate power

Use magnets with awareness. Their immense force can shock even experienced users. Be vigilant and respect their power.

Precision electronics

Remember: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
