Pulling power drops significantly with every subsequent millimeter of distance. Remember that even a very thin break (e.g., contamination, paint, dust) strongly weakens the grip. Neodymiums operate optimally at the point of direct contact; air break kills the force. See how quickly the pull force plummet, when the magnet does not adhere directly to the steel surface. When planning the assembly, eliminate redundant distances.

The table below defines the estimated holding capacity needed to start the sliding of the magnet down against a upright steel plate (considering typical friction). This value is relative to the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 20x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.08 kg / 4.58 pounds 2079.0 g / 20.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.39 kg / 3.06 pounds 1386.0 g / 13.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.69 kg / 1.53 pounds 693.0 g / 6.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.47 kg / 7.64 pounds 3465.0 g / 34.0 N

When mounting a holder on a upright surface (e.g., a fridge), it will maintain barely approx. 1/5 of its maximum pull force. Gravity and a weak degree of grip mean that products slip faster than they pull off. Planning a hanger? Note that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the element will slip down under a much lighter weight. Utilizing a rubberized pad can effectively increase the grip.

12 mm	100%	6.93 kg / 15.28 pounds 6930.0 g / 68.0 N

A thin metal plate is not enough to focus the full magnetic flux, which squanders power of the magnet. If you install a neodymium to a thin surface, the flux will pass right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you require a sufficiently solid element of steel. The saturation phenomenon means that on delicate walls (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel cross-section according to the table below.

Ordinary NdFeB products change their properties strength past the thermal threshold. Protect against heat – heat can irreversibly demagnetize this product. With every degree above norm, the magnet's capacity momentarily drops. Do not use this product in hot environments exceeding its safe range. Too high temperature will cause permanent loss of magnetism.

*Important note: Thermal stability is determined by both grade, but also on the magnet's shape. Flat magnets (pancake types) may lose charge permanently sooner than taller cylinders. The danger warning in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums interact from a wider radius than a magnet and sheet combination. Such a system of two magnets creates a more powerful interaction and a larger range of operation. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the collision energy is extreme. The levitation is slightly lower than the connection force, but still large.
*The magnetic induction between like poles is approximately ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Attention: Calculations demonstrate friction force of dual same magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a large risk to electronic devices as well as medical implants. These NdFeB products generate a field that destroys function of digital equipment. Notice: the invisible magnetic field penetrates the body and glass. Exceptional care must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - collision effects
MW 20x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	25.63 km/h (7.12 m/s)	0.30 J
30 mm	42.39 km/h (11.77 m/s)	0.82 J
50 mm	54.70 km/h (15.19 m/s)	1.36 J
100 mm	77.35 km/h (21.49 m/s)	2.72 J

NdFeB products are delicate – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Impact energy can cause material chips or painful pinches to skin. Be sure to control the product during mounting so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Use safety goggles when playing with large magnets.

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

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Note: On a vertical wall, the magnet holds merely ~20% of its nominal pull.

2. Efficiency vs thickness

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

3. Thermal stability

*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) = 0.35

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 a very strong rod magnet, composed of modern NdFeB material, which, at dimensions of Ø20x5 mm, guarantees optimal power. This specific item is characterized by high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 6.93 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 67.95 N with a weight of only 11.78 g, this rod is indispensable in miniature devices 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 long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø20x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø20x5 mm, which, at a weight of 11.78 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 6.93 kg (force ~67.95 N), which, with such defined dimensions, proves the high grade of the NdFeB material. 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 20 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.

Pros as well as cons of neodymium magnets.

Strengths

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

Their power remains stable, and after around ten years it drops only by ~1% (according to research),
They are noted for resistance to demagnetization induced by external disturbances,
In other words, due to the reflective surface of silver, the element gains a professional look,
They are known for high magnetic induction at the operating surface, which improves attraction properties,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of precise machining as well as adapting to atypical applications,
Wide application in modern industrial fields – they find application in hard drives, electric motors, precision medical tools, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in compact constructions

Disadvantages

Disadvantages of NdFeB magnets:

At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited ability of making threads in the magnet and complex shapes - recommended is a housing - magnet mounting.
Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

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

Magnet power was determined for optimal configuration, including:

using a base made of mild steel, acting as a magnetic yoke
whose transverse dimension equals approx. 10 mm
with an ideally smooth touching surface
with total lack of distance (without impurities)
for force applied at a right angle (in the magnet axis)
at ambient temperature room level

Practical aspects of lifting capacity – factors

Bear in mind that the magnet holding will differ subject to elements below, in order of importance:

Gap (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, rust or debris).
Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be wasted to the other side.
Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Thermal factor – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was measured with the use of a polished steel plate of optimal 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 lowers the lifting capacity.

Safe handling of neodymium magnets

Allergy Warning

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness appears, immediately stop working with magnets and use protective gear.

No play value

Absolutely store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.

Finger safety

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

Impact on smartphones

Remember: rare earth magnets generate a field that interferes with precision electronics. Keep a separation from your phone, device, and GPS.

Do not overheat magnets

Do not overheat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Life threat

Patients with a ICD must keep an absolute distance from magnets. The magnetic field can interfere with the functioning of the implant.

Caution required

Handle magnets with awareness. Their powerful strength can shock even experienced users. Plan your moves and do not underestimate their power.

Mechanical processing

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Shattering risk

Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.

Magnetic media

Do not bring magnets near a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
