Magnetic force drops significantly with every mm of distance. Remember that every additional insulation layer (e.g., dirt, paint, rust) noticeably weakens the grip. Magnets operate optimally during direct contact; gap nullifies the power. Notice how rapidly the pull force drop, when the product does not adhere directly to the metal substrate. When planning the arrangement, eliminate redundant distances.

The table below indicates the estimated holding capacity required to initiate the sliding of the magnet down on a vertical metal surface (considering standard friction coefficient). This parameter is relative to the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 8x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.65 kg / 1.44 LBS 651.0 g / 6.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.43 kg / 0.96 LBS 434.0 g / 4.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 0.48 LBS 217.0 g / 2.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.09 kg / 2.39 LBS 1085.0 g / 10.6 N

When hanging a magnet on a upright plane (e.g., a car body), it you can count on just about 1/5 of its maximum pull force. Gravity and a weak degree of grip cause that products move down easier than they pop off the substrate. Want to create a wall mount? Note that the shear force is much weaker than the maximum static pull force. On a painted metal, the element will give way down under a significantly smaller cargo. Utilizing a rubberized coating can drastically improve the result.

A thin metal plate is unable to focus the full magnetic flux, which wastes potential of the magnet. 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 magnet's power, you need a suitably thick piece of steel. The saturation phenomenon means that on sheet metal structures (e.g., car bodies), the product shows lower pull force. We recommend selecting the steel thickness from these parameters.

Classic neodymiums lose strength after exceeding the maximum temperature. Avoid high temperatures – heat can irreversibly destroy this magnet. As the temperature rises, the neodymium's capacity momentarily lowers. Refrain from using this product close to ovens exceeding its working range. Ignoring the limit will lead to permanent loss of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) risk losing magnetic properties sooner compared to rod magnets. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a much further distance than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Designing a strong closure? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Important: Results apply to shear force of two identical magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a real danger to electronics as well as medical implants. These magnets generate a flux that prevents correct functioning of digital equipment. Notice: the unseen radiation acts through matter and housings. Special caution must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Striking energy can cause material chips or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when working with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Note: On a vertical wall, the magnet retains only a fraction of its perpendicular strength.

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly limits the holding force.

3. Power loss vs temp

*For standard magnets, 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) = 0.68

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 exceptionally strong cylindrical magnet, produced from modern NdFeB material, which, with dimensions of Ø8x5 mm, guarantees the highest energy density. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 2.17 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 21.31 N with a weight of only 1.88 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø8x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø8x5 mm, which, at a weight of 1.88 g, makes it an element with impressive magnetic energy density. The value of 21.31 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.88 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 5 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 diametrically if your project requires it.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

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

They retain attractive force for around ten years – the drop is just ~1% (based on simulations),

By covering with a shiny layer of gold, the element has an aesthetic look,
Magnetic induction on the working part of the magnet is strong,
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 custom forming and adapting to precise needs,
Versatile presence in modern technologies – they find application in computer drives, drive modules, medical devices, and other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Limitations

Drawbacks and weaknesses of neodymium magnets and ways of using them

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their 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
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing threads and complicated forms in magnets, we recommend using cover - magnetic mechanism.
Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Magnetic strength at its maximum – what affects it?

Breakaway force is the result of a measurement for optimal configuration, taking into account:

using a base made of low-carbon steel, serving as a magnetic yoke
possessing a thickness of at least 10 mm to avoid saturation
with a plane free of scratches
without the slightest insulating layer between the magnet and steel
during detachment in a direction vertical to the plane
at temperature room level

What influences lifting capacity in practice

Holding efficiency impacted by working environment parameters, including (from priority):

Gap (between the magnet and the plate), since even a very small distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Safety rules for work with neodymium magnets

Do not overheat magnets

Control the heat. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.

Handling guide

Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Think ahead.

Data carriers

Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.

Pinching danger

Big blocks can break fingers instantly. Do not place your hand betwixt two attracting surfaces.

Adults only

Only for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep out of reach of children and animals.

Keep away from electronics

Remember: rare earth magnets generate a field that disrupts precision electronics. Maintain a safe distance from your mobile, device, and GPS.

Implant safety

People with a heart stimulator must maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the implant.

Beware of splinters

Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them breaking into small pieces.

Nickel allergy

Certain individuals experience a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Frequent touching may cause an allergic reaction. We strongly advise wear safety gloves.

Do not drill into magnets

Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
