Magnetic force drops significantly with every subsequent millimeter of gap. Remember that even a very thin break (e.g., dirt, varnish, veneer) noticeably diminishes the holding power. Magnetic products operate most effectively in perfect adhesion; gap weakens the force. Observe how flashily the pull force fall, when the product does not touch flatly to the steel surface. When designing the assembly, avoid unnecessary gaps.

The table below calculates the theoretical weight limit sufficient to cause the downward movement of the magnet vertically on a vertical metal surface (considering standard friction). This value varies with the distance between the magnet and the metal.

When hanging a magnet on a vertical wall (e.g., a fridge), it you can count on barely about 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip cause that products move down faster than they pull off. Planning a vertical fastening? Note that the shear force is much weaker than the maximum static pull force. On a smooth steel, the magnet will give way down under a noticeably lighter load. Utilizing a rubberized coating can significantly increase the grip.

A thin metal plate is unable to take in the entire magnetic field, which wastes potential of the magnet. If you mount a strong magnet to a weak sheet, the flux will pass right through and the attraction force will be weaker. To utilize full efficiency of this magnet's power, you need a suitably thick element of metal. The saturation effect causes that on thin elements (e.g., thin profiles), the product holds weaker. We recommend selecting the steel dimension according to the table below.

Standard neodymium magnets irreversibly lose parameters after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly demagnetize this magnet. As the temperature rises, the magnet's power briefly decreases. Refrain from using this product in hot environments exceeding its working range. Too high temperature will lead to irreversible degradation of magnetism.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) may lose charge permanently sooner than taller cylinders. The danger warning in the table points to a risk of irreversible loss 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 creates a more powerful interaction and a larger range of operation. Planning to create a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the pinch force is extreme. The levitation is slightly lower than the attraction, but still large.
*The magnetic induction in repulsion mode drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
Note: Estimates refer to shear force of two same neodymium magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a serious hazard to IT equipment and pacemakers. These magnets produce a field that destroys function of digital equipment. Be aware: the invisible magnetic field passes through tissues and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

NdFeB products are prone to chipping – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Impact energy can destroy the magnet or injury to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when playing with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Note: On a vertical surface, the magnet holds only approx. 20-30% of its perpendicular strength.

2. Steel saturation

*Thin steel (e.g. computer case) drastically weakens the holding force.

3. Heat tolerance

*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) = 0.16

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.

The presented product is an extremely powerful rod magnet, produced from advanced NdFeB material, which, at dimensions of Ø100x10 mm, guarantees the highest energy density. The MW 100x10 / N38 component is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 40.86 kg), this product is in stock 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, guaranteeing an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 400.80 N with a weight of only 589.05 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for 90% of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø100x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 100 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 40.86 kg (force ~400.80 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it 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 100 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.

Strengths as well as weaknesses of rare earth magnets.

Pros

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

Their magnetic field is durable, and after approximately ten years it drops only by ~1% (theoretically),
They are noted for resistance to demagnetization induced by external field influence,
A magnet with a smooth nickel surface has better aesthetics,
Magnets have exceptionally strong magnetic induction on the active area,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
Possibility of detailed machining as well as modifying to defined needs,
Significant place in high-tech industry – they are utilized in magnetic memories, electric motors, medical equipment, also industrial machines.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in creating threads and complex forms in magnets, we recommend using a housing - magnetic holder.
Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Pull force analysis

Best holding force of the magnet in ideal parameters – what it depends on?

Breakaway force was determined for optimal configuration, assuming:

on a base made of structural steel, perfectly concentrating the magnetic flux
possessing a massiveness of minimum 10 mm to avoid saturation
characterized by lack of roughness
without the slightest clearance between the magnet and steel
for force applied at a right angle (in the magnet axis)
at ambient temperature room level

What influences lifting capacity in practice

In real-world applications, the actual holding force results from many variables, listed from crucial:

Clearance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.

H&S for magnets

Bodily injuries

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

Do not overheat magnets

Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.

Product not for children

Absolutely store magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are fatal.

Risk of cracking

Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.

Safe distance

Data protection: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Warning for allergy sufferers

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, cease working with magnets and wear gloves.

Pacemakers

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

Handling rules

Handle with care. Neodymium magnets act from a long distance and connect with massive power, often quicker than you can move away.

Phone sensors

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

Fire risk

Powder created during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Important! More info about risks in the article: Magnet Safety Guide.
