Magnetic force decreases sharply with every subsequent millimeter of gap. Note that even the smallest gap (e.g., contamination, paint, dust) significantly reduces the pull force. Magnetic products work most effectively during direct contact; distance drastically cuts the force. See how flashily the parameters drop, when the magnet does not adhere tightly to the steel surface. When calculating the mounting, discard redundant distances.

This section calculates the estimated force required to initiate the slippage of the magnet downwards on a vertical steel plate (assuming standard friction coefficient). The holding force depends on the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MW 50x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	21.03 kg / 46.36 lbs 21030.0 g / 206.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	14.02 kg / 30.91 lbs 14020.0 g / 137.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	7.01 kg / 15.45 lbs 7010.0 g / 68.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	35.05 kg / 77.27 lbs 35050.0 g / 343.8 N

When hanging a element on a upright plane (e.g., a car body), it you can count on just approx. 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip mean that products move down faster than they pull off. Designing a wall mount? Remember that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slide down under a noticeably lighter weight. Utilizing a rubberized coating can significantly raise the stability.

3 mm	25%	17.53 kg / 38.64 lbs 17525.0 g / 171.9 N
5 mm	42%	29.21 kg / 64.39 lbs 29208.3 g / 286.5 N
10 mm	83%	58.42 kg / 128.79 lbs 58416.7 g / 573.1 N
11 mm	92%	64.26 kg / 141.67 lbs 64258.3 g / 630.4 N
12 mm	100%	70.10 kg / 154.54 lbs 70100.0 g / 687.7 N

A thin sheet cannot conduct the full magnetic flux, which wastes potential of the holder. Should you mount a strong magnet to a thin surface, the field will pass right through and the attraction force will be weaker. To squeeze the maximum of this magnet's potential, you need a suitably thick piece of metal. The saturation phenomenon means that on sheet metal structures (e.g., car bodies), the magnet holds weaker. We advise picking the steel cross-section according to the table below.

Ordinary NdFeB products lose strength past the thermal threshold. Avoid high temperatures – high temperature can permanently destroy this product. With every degree above norm, the magnet's capacity momentarily drops. Refrain from using this magnet in hot environments exceeding its working range. Too high temperature will cause destruction of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than long magnets. Warning indicator in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. The setup of magnet-to-magnet produces a massive flux and a larger range of operation. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the collision energy is huge. The levitation is slightly lower than the attraction, but still large.
*Field value between like poles reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
Important: Calculations show sliding force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a large risk to electronics as well as medical implants. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation penetrates the body and housings. Increased vigilance must be taken by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are very brittle – a collision with steel can result in shattering. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can cause material chips or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed means shattering of the neodymium. Wear safety glasses when handling with large magnets.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Vertical hold

*Warning: On a vertical wall, the magnet retains only approx. 20-30% of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) severely reduces the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.50

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 a very strong cylinder magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø50x20 mm, guarantees the highest energy density. This specific item is characterized by high dimensional repeatability and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 70.10 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 687.66 N with a weight of only 294.52 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are suitable for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø50x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø50x20 mm, which, at a weight of 294.52 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 70.10 kg (force ~687.66 N), which, with such compact 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.

This cylinder is magnetized axially (along the height of 20 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 and weaknesses of neodymium magnets.

Advantages

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

Their magnetic field is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
They are noted for resistance to demagnetization induced by presence of other magnetic fields,
Thanks to the metallic finish, the plating of nickel, gold, or silver gives an elegant appearance,
The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to the possibility of flexible forming and adaptation to custom solutions, neodymium magnets can be produced in a broad palette of shapes and sizes, which amplifies use scope,
Fundamental importance in high-tech industry – they are used in magnetic memories, electric motors, advanced medical instruments, and modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength 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 recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
We recommend cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical in case of swallowing.
With mass production the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum lifting capacity of the magnet – what it depends on?

The lifting capacity listed is a result of laboratory testing performed under standard conditions:

using a plate made of high-permeability steel, functioning as a magnetic yoke
possessing a thickness of min. 10 mm to avoid saturation
with a surface free of scratches
without any insulating layer between the magnet and steel
during pulling in a direction vertical to the plane
in temp. approx. 20°C

Practical aspects of lifting capacity – factors

Holding efficiency is affected by specific conditions, such as (from priority):

Distance – the presence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
Base massiveness – too thin plate does not accept the full field, causing part of the flux to be lost to the other side.
Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
Plate texture – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was measured by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.

Warnings

Machining danger

Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.

Physical harm

Pinching hazard: The pulling power is so immense that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Choking Hazard

Absolutely store magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are fatal.

Skin irritation risks

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease handling magnets and wear gloves.

Magnetic interference

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

Life threat

Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.

Safe operation

Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Power loss in heat

Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

Data carriers

Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Shattering risk

Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
