Pulling power weakens sharply with every subsequent millimeter of gap. Remember that every additional insulation layer (e.g., dirt, paint, dust) strongly diminishes the holding power. Magnets work optimally in perfect adhesion; air break drastically cuts the force. Analyze how flashily the load capacity fall, when the product does not touch directly to the metal substrate. When designing the arrangement, eliminate additional spacers.

The following data defines the theoretical weight limit necessary to cause the shifting of the magnet vertically on a vertical metal surface (considering typical friction). The holding force is relative to the separation distance between the magnet and the metal.

When mounting a holder on a upright wall (e.g., a fridge), it you can count on just approx. 1/5 of its maximum pull force. Gravity as well as a low friction coefficient mean that magnets slip faster than they pull off. Designing a vertical fastening? Consider that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the holder will slide down under a much lighter weight. Using a rubber coating can drastically increase the grip.

A too thin steel is incapable of take in the entire magnetic field, which wastes potential of the holder. If you install a neodymium to a thin surface, the field will penetrate right through and the attraction force will be weaker. To utilize 100% of this magnet's potential, you require a sufficiently solid element of steel. The saturation effect means that on delicate walls (e.g., appliance housings), the magnet works worse. We suggest choosing the steel cross-section based on the following data.

Classic neodymiums irreversibly lose power past the thermal threshold. Protect against heat – excessive heat can irreversibly destroy this product. With increasing heat, the magnet's power temporarily lowers. Do not use this magnet close to heaters exceeding its working range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) are more susceptible to demagnetization at lower temperatures than long magnets. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a wider radius than a magnet and sheet combination. Such a system of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Planning to create a strong closure? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the collision energy is massive. The repulsion force is marginally weaker than the attraction, but still impressive.
*Flux density in repulsion mode drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Estimates demonstrate sliding force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to IT equipment as well as pacemakers. These neodymiums generate a field that prevents correct functioning of digital equipment. Be aware: the unseen radiation acts through matter and plastic. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

NdFeB products are very brittle – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when playing with powerful specimens.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. 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 a fraction of its perpendicular strength.

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Temperature resistance

*For N38 grade, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.49

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. 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 cylinder magnet, manufactured from modern NdFeB material, which, with dimensions of Ø12x50 mm, guarantees optimal power. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 2.62 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 25.73 N with a weight of only 42.41 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

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 automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets N38 are suitable for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø12x50), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 12 mm and height 50 mm. The key parameter here is the holding force amounting to approximately 2.62 kg (force ~25.73 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against oxidation, 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 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.

Pros as well as cons of neodymium magnets.

Benefits

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

They retain attractive force for almost ten years – the drop is just ~1% (in theory),
They retain their magnetic properties even under close interference source,
The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnetic induction on the working layer of the magnet turns out to be extremely intense,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Possibility of exact creating as well as optimizing to concrete applications,
Huge importance in modern technologies – they serve a role in magnetic memories, electromotive mechanisms, precision medical tools, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in miniature devices

Weaknesses

Disadvantages of neodymium magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited ability of producing nuts in the magnet and complex forms - preferred is cover - magnet mounting.
Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, small components of these devices can be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets is a challenge,

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

Information about lifting capacity was defined for optimal configuration, taking into account:

using a sheet made of low-carbon steel, functioning as a magnetic yoke
with a thickness minimum 10 mm
with an ideally smooth touching surface
without the slightest air gap between the magnet and steel
under axial application of breakaway force (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

Effective lifting capacity is influenced by specific conditions, such as (from most important):

Gap (between the magnet and the plate), since even a very small distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
Direction of force – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Chemical composition of the base – mild steel gives the best results. Alloy steels lower magnetic properties and lifting capacity.
Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.

Precautions when working with neodymium magnets

Danger to the youngest

Always keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.

Caution required

Be careful. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can react.

Crushing force

Large magnets can smash fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.

Warning for heart patients

Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Phone sensors

A strong magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Do not bring magnets near a device to prevent damaging the sensors.

Beware of splinters

NdFeB magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets will cause them breaking into shards.

Threat to electronics

Equipment safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

Avoid contact if allergic

A percentage of the population have a contact allergy to nickel, which is the common plating for NdFeB magnets. Frequent touching can result in skin redness. We suggest use safety gloves.

Mechanical processing

Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.

Do not overheat magnets

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