Technical analysis of the magnet - technical parameters

The following values represent the direct effect of a mathematical simulation. Results were calculated on algorithms for the class Nd₂Fe₁₄B. Actual performance may differ. Use these calculations as a preliminary roadmap during assembly planning.

Table 1: Static pull force (pull vs distance) - characteristics
MW 10x10 / N38

Distance (mm)	Induction (Gauss) / mT	Pull Force (kg/lbs/g/N)	Risk Status
0 mm	5534 Gs 553.4 mT	3.18 kg / 7.01 lbs 3180.0 g / 31.2 N	strong

50 mm	9 Gs 0.9 mT	0.00 kg / 0.00 lbs 0.0 g / 0.0 N	weak grip

Grip strength drops drastically per each millimeter of distance. Keep in mind that even a microscopic distance (e.g., dirt, paint, dust) strongly reduces the pull force. Magnetic products work optimally during direct contact; distance drastically cuts the force. Notice how flashily the parameters drop, when the product does not touch tightly to the steel surface. When calculating the arrangement, eliminate redundant distances.

Table 2: Slippage capacity (vertical surface)
MW 10x10 / N38

Distance (mm)	Friction coefficient	Pull Force (kg/lbs/g/N)
0 mm	Stal (~0.2)	0.64 kg / 1.40 lbs 636.0 g / 6.2 N

50 mm	Stal (~0.2)	0.00 kg / 0.00 lbs 0.0 g / 0.0 N

The table below defines the estimated holding capacity needed to start the slippage of the magnet vertically against a vertical steel plate (considering typical friction). This value depends on the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 10x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.95 kg / 2.10 lbs 954.0 g / 9.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.64 kg / 1.40 lbs 636.0 g / 6.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.32 kg / 0.70 lbs 318.0 g / 3.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.59 kg / 3.51 lbs 1590.0 g / 15.6 N

When placing a element on a vertical plane (e.g., a board), it will only hold only approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip cause that products move down faster than they detach. Designing a vertical fastening? Remember that the shear force is significantly lower than the maximum static pull force. On a painted metal, the element will slide down under a noticeably lighter cargo. Application of an anti-slip layer can significantly raise the stability.

3 mm	75%	2.39 kg / 5.26 lbs 2385.0 g / 23.4 N
5 mm	100%	3.18 kg / 7.01 lbs 3180.0 g / 31.2 N
10 mm	100%	3.18 kg / 7.01 lbs 3180.0 g / 31.2 N
11 mm	100%	3.18 kg / 7.01 lbs 3180.0 g / 31.2 N
12 mm	100%	3.18 kg / 7.01 lbs 3180.0 g / 31.2 N

A thin sheet is unable to absorb the full magnetic flux, which weakens actual performance of the holder. If you install a neodymium to a weak sheet, the field will pass right through and the attraction force will be weaker. To achieve 100% of this magnet's potential, you require a sufficiently solid backing of steel. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the product shows lower pull force. We suggest choosing the steel thickness from these parameters.

Classic neodymiums change their properties power after exceeding the maximum temperature. Watch out for overheating – heat can permanently demagnetize this product. With increasing heat, the magnet's force briefly drops. Do not use this magnet in hot environments higher than its working range. Ignoring the limit will result in irreversible degradation of magnetic properties.

*Technical advisory: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) risk losing magnetic properties sooner than long magnets. Warning indicator in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a much further distance than a magnet and sheet setup. Such a system of two magnets generates a stronger field and a larger range of performance. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the impact force is huge. The levitation is marginally weaker than the attraction, but still large.
*Field value in repulsion mode reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Note: Figures refer to sliding force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Protective zones (implants) - precautionary measures
MW 10x10 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	6.5 cm
Hearing aid	10 Gs (1.0 mT)	5.0 cm
Timepiece	20 Gs (2.0 mT)	4.0 cm

Powerful magnet radiation is a real danger to IT equipment and pacemakers. These magnets generate a flux that prevents correct functioning of digital equipment. Remember: the unseen radiation penetrates the body and plastic. Exceptional care must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - warning

100 mm	74.10 km/h (20.58 m/s)	1.25 J

Magnetic elements are prone to chipping – a violent impact against metal risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when handling with large magnets.

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

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Caution: On a vertical surface, the magnet retains only approx. 20-30% of its max power.

2. Steel saturation

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

3. Heat tolerance

*For N38 material, 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) = 0.89

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, made from modern NdFeB material, which, at dimensions of Ø10x10 mm, guarantees the highest energy density. The MW 10x10 / N38 component features a tolerance 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. 3.18 kg), this product is available off-the-shelf 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 successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 31.15 N with a weight of only 5.89 g, this cylindrical magnet 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 professional component. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are strong enough for the majority 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 (Ø10x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 10 mm. The key parameter here is the lifting capacity amounting to approximately 3.18 kg (force ~31.15 N), which, with such defined dimensions, proves the high power of the NdFeB material. 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 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 through the diameter if your project requires it.

Strengths and weaknesses of rare earth magnets.

Benefits

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

They retain full power for nearly 10 years – the drop is just ~1% (according to analyses),
They do not lose their magnetic properties even under strong external field,
In other words, due to the glossy finish of silver, the element gains a professional look,
Neodymium magnets deliver maximum magnetic induction on a small area, which increases force concentration,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of detailed forming and adapting to complex requirements,
Huge importance in innovative solutions – they serve a role in data components, drive modules, precision medical tools, also multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of neodymium magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets suffer a drop in power. 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
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
Due to limitations in realizing nuts and complicated forms in magnets, we propose using a housing - magnetic holder.
Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these products can be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Highest magnetic holding force – what affects it?

The load parameter shown refers to the limit force, recorded under ideal test conditions, namely:

with the application of a sheet made of special test steel, ensuring full magnetic saturation
whose transverse dimension is min. 10 mm
with an ground contact surface
without the slightest clearance between the magnet and steel
during detachment in a direction vertical to the mounting surface
in neutral thermal conditions

Magnet lifting force in use – key factors

Effective lifting capacity impacted by specific conditions, including (from most important):

Air gap (between the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Load vector – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Material type – ideal substrate is high-permeability steel. Hardened steels may attract less.
Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.

Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.

Safety rules for work with neodymium magnets

Protect data

Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).

Life threat

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Dust is flammable

Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.

Finger safety

Big blocks can crush fingers in a fraction of a second. Do not place your hand between two strong magnets.

Skin irritation risks

It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, avoid touching magnets with bare hands or opt for versions in plastic housing.

Material brittleness

Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.

Impact on smartphones

Be aware: neodymium magnets generate a field that interferes with precision electronics. Maintain a separation from your mobile, tablet, and GPS.

Conscious usage

Exercise caution. Neodymium magnets act from a distance and connect with massive power, often faster than you can react.

Swallowing risk

Neodymium magnets are not toys. Accidental ingestion of multiple magnets may result in them attracting across intestines, which constitutes a critical condition and requires immediate surgery.

Heat sensitivity

Watch the temperature. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
