Pulling power drops sharply with every subsequent millimeter of spacing. Keep in mind that every additional insulation layer (e.g., contamination, varnish, veneer) noticeably diminishes the holding power. Neodymiums hold optimally at the point of direct contact; gap drastically cuts the force. Observe how flashily the parameters fall, when the product does not adhere directly to the steel surface. When designing the assembly, discard additional spacers.

The table below presents the approximate shear load required to initiate the sliding of the magnet vertically along a vertical metal surface (assuming typical friction coefficient). This parameter is relative to the air gap between the magnet and the surface.

When hanging a holder on a upright plane (e.g., a fridge), it will only hold just approx. 20%-30% of nominal attraction strength. Gravitational force as well as a weak degree of grip cause that magnets move down easier than they detach. Designing a hanger? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will give way down under a noticeably lighter cargo. Utilizing a rubberized layer can significantly increase the grip.

A too thin steel is incapable of take in the entire magnetic field, which wastes potential of the magnet. If you install a neodymium to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To squeeze the maximum of this neodymium's potential, you need a suitably thick element of steel. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the magnet holds weaker. We suggest choosing the steel thickness based on the following data.

Classic neodymiums lose parameters past the thermal threshold. Watch out for overheating – high temperature can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's force briefly drops. Refrain from using this magnet close to ovens exceeding its working range. Too high temperature will result in irreversible degradation of magnetism.

*Technical advisory: Thermal stability is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) risk losing magnetic properties 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 interact from a much further distance than a magnet and sheet setup. The connection of magnet-to-magnet produces a massive flux and a larger range of operation. Want to build a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the pinch force is huge. The repulsion force is slightly lower than the connection force, but still large.
*Field value between like poles drops to ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Attention: Results demonstrate sliding force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (implants) - precautionary measures

Extremely neodym field poses a real danger to electronics as well as pacemakers. These magnets produce a flux that prevents correct functioning of digital equipment. Notice: the invisible magnetic field acts through matter and housings. Special caution must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

NdFeB products are very brittle – a violent impact against metal can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or painful pinches to skin. Hold the magnet firmly during installation so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when handling with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Note: On a vertical surface, the magnet retains merely approx. 20-30% of its max power.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly reduces 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) = 0.71

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 an exceptionally strong cylindrical magnet, composed of advanced NdFeB material, which, at dimensions of Ø12x8 mm, guarantees optimal power. The MW 12x8 / N38 component is characterized by an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 4.93 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 48.32 N with a weight of only 6.79 g, this rod is indispensable in electronics 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 two-component epoxy glues. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel 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 even stronger magnets in the same volume (Ø12x8), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø12x8 mm, which, at a weight of 6.79 g, makes it an element with impressive magnetic energy density. 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.

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 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 and weaknesses of neodymium magnets.

Advantages

Apart from their strong power, neodymium magnets have these key benefits:

They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
They are extremely resistant to demagnetization induced by external disturbances,
By applying a smooth coating of silver, the element gains an aesthetic look,
Magnets possess extremely high magnetic induction on the working surface,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Considering the ability of free shaping and adaptation to unique needs, magnetic components can be produced in a broad palette of geometric configurations, which makes them more universal,
Wide application in electronics industry – they are used in mass storage devices, motor assemblies, medical devices, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions

Weaknesses

Cons of neodymium magnets: tips and applications.

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
We warn that neodymium magnets can reduce their strength 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 rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
We suggest a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
Health risk resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these devices are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what affects it?

The force parameter is a result of laboratory testing conducted under standard conditions:

on a plate made of structural steel, perfectly concentrating the magnetic field
with a cross-section no less than 10 mm
characterized by even structure
with zero gap (without coatings)
during detachment in a direction perpendicular to the plane
at conditions approx. 20°C

Lifting capacity in practice – influencing factors

Real force is influenced by working environment parameters, mainly (from most important):

Clearance – existence of foreign body (rust, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
Direction of force – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Safe handling of neodymium magnets

GPS Danger

GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.

Risk of cracking

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

Skin irritation risks

It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, avoid direct skin contact and opt for coated magnets.

Safe operation

Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and respect their force.

Danger to pacemakers

Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Power loss in heat

Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.

Bodily injuries

Watch your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Machining danger

Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Danger to the youngest

Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Store out of reach of children and animals.

Threat to electronics

Device Safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
