Pulling power weakens drastically per each millimeter of gap. Keep in mind that even a microscopic distance (e.g., dirt, varnish, dust) significantly reduces the pull force. Neodymiums operate optimally during direct contact; distance nullifies the power. Notice how flashily the pull force fall, when the magnet does not touch directly to the metal substrate. When designing the assembly, discard redundant distances.

The following data indicates the theoretical holding capacity needed to cause the shifting of the magnet down against a upright steel plate (considering typical friction). This parameter is relative to the distance between the magnet and the surface.

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.52 kg / 1.16 LBS 524.0 g / 5.1 N

When hanging a holder on a vertical wall (e.g., a car body), it will maintain barely about 1/5 of its nominal power. Gravitational force as well as a low friction coefficient mean that products slide down easier than they detach. Planning a hanger? Note that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a noticeably lighter weight. Application of an anti-slip layer can drastically raise the stability.

A thin sheet is not enough to absorb the entire magnetic field, which weakens actual performance of the holder. If you install a neodymium to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To achieve 100% of this magnet's power, you require a sufficiently solid backing of steel. The saturation phenomenon means that on thin elements (e.g., thin profiles), the product shows lower pull force. We advise picking the steel thickness according to the table below.

Ordinary NdFeB products change their properties parameters after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently demagnetize this magnet. With every degree above norm, the magnet's capacity briefly lowers. Avoid using this product in hot environments exceeding its working range. Too high temperature will lead to irreversible degradation of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) are more susceptible to demagnetization at lower temperatures than taller cylinders. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a wider radius than a magnet and steel combination. The connection of magnet-to-magnet produces a massive flux and a further horizon of operation. Planning to create a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is massive. The repulsion force is marginally weaker than the connection force, but still impressive.
*Field value between like poles drops to ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
* Results demonstrate sliding force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to electronic devices and medical implants. These neodymiums produce a field that destroys function of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a strong collision with metal risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or injury to skin. Be sure to control the product 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. Use safety goggles when handling with large magnets.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Caution: On a vertical surface, the magnet retains just a fraction of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely limits the holding force.

3. Temperature resistance

*For standard magnets, 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) = 1.49

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.

The offered product is an extremely powerful cylinder magnet, composed of modern NdFeB material, which, with dimensions of Ø12x50 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 2.62 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a positioning 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 low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. 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 popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need even stronger magnets in the same volume (Ø12x50), 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 12 mm and height 50 mm. The value of 25.73 N means that the magnet is capable of holding a weight many times exceeding its own mass of 42.41 g. 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 12 mm. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. 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

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

They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
Neodymium magnets are distinguished by remarkably resistant to loss of magnetic properties caused by external interference,
In other words, due to the reflective surface of gold, the element gains a professional look,
Magnets are distinguished by maximum magnetic induction on the working surface,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
Considering the possibility of accurate molding and customization to unique solutions, NdFeB magnets can be manufactured in a wide range of geometric configurations, which amplifies use scope,
Versatile presence in innovative solutions – they serve a role in mass storage devices, electric motors, medical equipment, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in small systems

Cons

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength 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
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing threads and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

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

The force parameter is a theoretical maximum value performed under the following configuration:

with the application of a sheet made of special test steel, ensuring maximum field concentration
possessing a thickness of minimum 10 mm to avoid saturation
with a plane free of scratches
without any insulating layer between the magnet and steel
for force applied at a right angle (in the magnet axis)
in stable room temperature

Determinants of practical lifting force of a magnet

Holding efficiency impacted by specific conditions, including (from priority):

Distance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic permeability and lifting capacity.
Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
Heat – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.

Warnings

Keep away from electronics

Note: neodymium magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.

Do not underestimate power

Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Threat to electronics

Do not bring magnets close to a wallet, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.

Fire warning

Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Implant safety

Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.

Material brittleness

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

This is not a toy

Always store magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are tragic.

Operating temperature

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

Allergic reactions

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.

Bone fractures

Pinching hazard: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
