Magnetic force drops drastically per each millimeter of spacing. Remember that every additional insulation layer (e.g., contamination, varnish, veneer) strongly weakens the grip. Magnets operate most effectively at the point of direct contact; gap kills the force. See how quickly the load capacity drop, when the magnet does not touch tightly to the steel surface. When designing the assembly, discard additional spacers.

The following data shows the estimated weight limit sufficient to start the shifting of the magnet vertically against a upright steel wall (considering standard friction). This parameter is relative to the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 2x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.02 kg / 0.05 LBS 21.0 g / 0.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.01 kg / 0.03 LBS 14.0 g / 0.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.01 kg / 0.02 LBS 7.0 g / 0.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.04 kg / 0.08 LBS 35.0 g / 0.3 N

When hanging a element on a vertical wall (e.g., a car body), it will only hold just approx. 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip cause that magnets slide down faster than they detach. Want to create a hanger? Note that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the magnet will slide down under a noticeably lighter load. Application of an anti-slip coating can significantly raise the stability.

A thin metal plate cannot absorb the entire magnetic field, which weakens actual performance of the holder. Should you install a neodymium to a thin surface, the flux will pass right through and the holding will be smaller. To squeeze the maximum of this neodymium's potential, you require a sufficiently solid piece of steel. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the holder shows lower pull force. We advise picking the steel cross-section according to the table below.

Ordinary NdFeB products lose power past the thermal threshold. Watch out for overheating – high temperature can permanently demagnetize this product. With increasing heat, the neodymium's capacity briefly decreases. Do not use this magnet close to heaters higher than its operating temperature limit. Ignoring the limit will lead to destruction of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. Such a system of two magnets produces a massive flux and a further horizon of operation. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when connecting a pair of magnets, the collision energy is extreme. The levitation is a bit weaker than the attraction, but still significant.
*Flux density for N-N configuration drops to ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Note: Estimates show friction force of two matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a large risk to IT equipment as well as pacemakers. These magnets generate a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Magnetic elements are prone to chipping – a collision with steel causes immediate chipping. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can cause material chips or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Use safety goggles when playing 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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Caution: On a vertical surface, the magnet retains merely ~20% of its nominal pull.

2. Steel saturation

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

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.55

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 incredibly powerful cylindrical magnet, produced from durable NdFeB material, which, at dimensions of Ø2x10 mm, guarantees optimal power. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.07 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 0.70 N with a weight of only 0.24 g, this rod is indispensable in miniature devices and wherever every gram matters.

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 stability 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 high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø2x10), 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 2 mm and height 10 mm. The value of 0.70 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.24 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 10 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 through the diameter if your project requires it.

Strengths as well as weaknesses of rare earth magnets.

Strengths

Besides their stability, neodymium magnets are valued for these benefits:

They retain full power for nearly 10 years – the drop is just ~1% (in theory),
They have excellent resistance to magnetic field loss due to opposing magnetic fields,
In other words, due to the smooth surface of nickel, the element is aesthetically pleasing,
Neodymium magnets achieve maximum magnetic induction on a small surface, which ensures high operational effectiveness,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of custom creating as well as modifying to defined conditions,
Universal use in modern industrial fields – they find application in magnetic memories, electric motors, advanced medical instruments, as well as technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of NdFeB magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Due to limitations in realizing threads and complicated shapes in magnets, we propose using cover - magnetic holder.
Health risk to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

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

Magnet power is the result of a measurement for optimal configuration, taking into account:

with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
with a cross-section of at least 10 mm
with an ground contact surface
with direct contact (no impurities)
during pulling in a direction perpendicular to the mounting surface
in temp. approx. 20°C

Practical lifting capacity: influencing factors

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

Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Direction of force – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.

Safe handling of neodymium magnets

Keep away from children

Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Store away from children and animals.

Beware of splinters

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Data carriers

Do not bring magnets close to a wallet, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.

Caution required

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

Allergic reactions

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

ICD Warning

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.

Operating temperature

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

Bone fractures

Pinching hazard: The attraction force is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.

Machining danger

Machining of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Keep away from electronics

A powerful magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Keep magnets close to a device to prevent damaging the sensors.
