Pulling power weakens drastically with every mm of gap. Keep in mind that even a microscopic distance (e.g., contamination, paint, rust) significantly weakens the grip. Neodymiums work optimally during direct contact; gap weakens the power. Notice how rapidly the parameters fall, when the product does not adhere directly to the steel surface. When designing the mounting, discard unnecessary gaps.

The following data indicates the estimated shear load needed to cause the shifting of the magnet downwards against a vertical metal surface (assuming standard friction coefficient). This parameter depends on the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull

Raw steel	µ = 0.3 30% Nominalnej Siły	6.22 kg / 13.72 LBS 6222.0 g / 61.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.15 kg / 9.14 LBS 4148.0 g / 40.7 N

When mounting a holder on a vertical surface (e.g., a car body), it you can count on only about 1/5 of its nominal power. Gravity as well as a low friction coefficient mean that holders slide down faster than they pop off the substrate. Planning a vertical fastening? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a much lighter cargo. Application of an anti-slip pad can significantly raise the stability.

12 mm	100%	20.74 kg / 45.72 LBS 20740.0 g / 203.5 N

A thin metal plate is not enough to absorb the full magnetic flux, which squanders power of the holder. If you install a neodymium to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To utilize 100% of this magnet's potential, you require a sufficiently solid element of metal. The saturation effect means that on delicate walls (e.g., car bodies), the magnet works worse. We advise picking the steel cross-section according to the table below.

Classic neodymiums lose strength above the temperature limit. Avoid high temperatures – high temperature can irreversibly damage this product. As the temperature rises, the magnet's force temporarily decreases. Refrain from using this magnet in hot environments higher than its safe range. Too high temperature will result in permanent loss of magnetic properties.

*Important note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) may lose charge permanently at lower temperatures than taller cylinders. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnets interact from a significantly greater distance than a magnet and sheet combination. The setup of two magnets generates a stronger field and a wider radius of operation. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Remember that when bringing together two magnets, the collision energy is massive. The repulsion force is a bit weaker than the attraction, but still large.
*Field value between like poles reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Important: Estimates refer to sliding force of a pair of same magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a large risk to IT equipment and medical implants. These magnets produce a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field passes through tissues and housings. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a collision with steel causes immediate chipping. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Use safety goggles when working with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Note: On a vertical surface, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) drastically reduces the holding force.

3. Temperature resistance

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.45

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 extremely powerful rod magnet, composed of modern NdFeB material, which, with dimensions of Ø28.9x10 mm, guarantees the highest energy density. The MW 28.9x10 / N38 component is characterized by an accuracy of ±0.1mm and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 20.74 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 203.46 N with a weight of only 49.2 g, this rod is indispensable in electronics and wherever low weight is crucial.

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 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 (Ø28.9x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 28.9 mm and height 10 mm. The key parameter here is the lifting capacity amounting to approximately 20.74 kg (force ~203.46 N), which, with such defined dimensions, proves the high grade of the NdFeB material. 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 28.9 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 diametrically if your project requires it.

Pros and cons of rare earth magnets.

Strengths

Besides their remarkable field intensity, neodymium magnets offer the following advantages:

They retain full power for nearly ten years – the loss is just ~1% (in theory),
They maintain their magnetic properties even under external field action,
In other words, due to the aesthetic surface of silver, the element gains visual value,
The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Possibility of accurate modeling and adjusting to atypical applications,
Universal use in electronics industry – they are used in hard drives, electric motors, advanced medical instruments, also multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Drawbacks and weaknesses of neodymium magnets and ways of using them

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets experience a drop in force. 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
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated shapes.
Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these devices can be problematic in diagnostics medical when they are in the body.
With mass production the cost of neodymium magnets is a challenge,

Holding force characteristics

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

The specified lifting capacity represents the maximum value, recorded under ideal test conditions, specifically:

on a base made of mild steel, perfectly concentrating the magnetic flux
with a cross-section of at least 10 mm
characterized by even structure
without the slightest insulating layer between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at standard ambient temperature

Impact of factors on magnetic holding capacity in practice

Holding efficiency is influenced by specific conditions, such as (from most important):

Distance – existence of foreign body (paint, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
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 high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Safe handling of neodymium magnets

Beware of splinters

Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.

Caution required

Handle magnets with awareness. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.

Heat sensitivity

Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.

Choking Hazard

NdFeB magnets are not suitable for play. Swallowing several magnets may result in them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.

Medical interference

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Bodily injuries

Large magnets can break fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.

Metal Allergy

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.

Flammability

Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Electronic devices

Avoid bringing magnets near a purse, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.

Impact on smartphones
